Brief Introduction to Packaging Stretch Film

 

 

Stretch wrap or stretch film, sometimes known as pallet wrap, is a highly stretchable plastic film that is wrapped around items. The elastic recovery keeps the items tightly bound. In contrast, shrink wrap is applied loosely around an item and shrinks tightly with heat. While it is similar to plastic food wrap, it is not usually made of material rated as safe for food contact.
It is frequently used to secure pallet loads to one another but also may be used for bundling smaller items. Types of stretch film include bundling stretch film, hand stretch film, extended core stretch film, machine stretch film and static dissipative film.

 

What are Advantages of Packaging Stretch Film?

Economical
Stretch film is substantially less expensive to use than strapping materials or heat-shrinkable bags. Hand stretch films are capable of stretching in the 25-35% range. Machine-applied stretch film can be stretched anywhere from 75% to more than 200%. This means your roll price of film goes a long, long way.

Strong
An important feature of stretch film is memory; in other words, it wants to go back to its original length, like a rubber band. This means that once the film is stretched, it continues to exert a great deal of holding force on your load — keeping items securely in place, even during rough shipments. Stretch film can be punctured, but tears will not propagate, again keeping your items secured.

Transparent, Tinted or Opaque
The clarity of stretch film is important in many applications, such as when visible inspections are needed. If, however, you want your product to be unseen — for example, to deter theft or for color-coding in storage — tinted or opaque options are available.

Uv-Inhibiting Films

For outside storage and food products, UV protection is crucial, and stretch films with UV additives are readily available to meet the need.

Eco-Friendly

Stretch films are easily recyclable, and some films are manufactured with a percentage of recycled resins. Further, since stretch film stretches so much, relatively little packaging material is needed.

Safe

Strapping, the main alternative to stretch film, can cause injury when being applied or when being taken off a pallet. Stretch film is much safer to use.

Moisture Resistance

Another advantage of stretch film over strapping is a stretch-wrapped load is resistant to moisture — a key consideration for outside storage, shipment on flatbed trailers, etc.

Cast Stretch Film
Cast stretch film is made by applying a comprehensive manufacturing operation called cast extrusion. This action mandates the continual thrusting of a thermoplastic substrate into a flat die and onto a cooled roll.
The film gauge is resolved by how quickly the casting roll drags the plastic away from the die. This treatment causes cast films to boast superior clarity, allowing end users to observe the wrapped objects. This film stretches easier due to the molecules being aligned as they're extruded.
Cast stretch film is exceedingly quiet when removed from the roll and relatively simple to stretch. Cast stretch film also provides two-sided cling that grants wrapped products the ability to remain firmly wrapped during transportation.
While cast stretch film has multiple fantastic attributes, such as a more affordable cost than blown film, it does not hold a candle to blown film in sustaining strength or protection against tearing. Cast stretch film can generally stretch easily but has less robust stretch memory than other films.

 

Blown Stretch Film
Blown stretch film is created through a function called blown extrusion. This operation involves plastic melt being pushed into a circular slit die, resulting in a refined tube.
Next, the air is pushed into the tube, granting the volume of air enclosed to expand the tube to the optimal width. The tube is topped with an air ring which is then blown onto the substrate to chill. Chilling the material provides the blown film with greater strength and flexibility than other wraps.
As blown film is generally more robust than most other stretch wraps, it also boasts excellent resistance to tearing.
This is advantageous when containing loads with pointy edges vulnerable to collapsing thinner films. Blown films provide a high degree of memory when stretched. This means that packages remain secured.
Unfortunately, blown film is more expensive and has poorer transparency than other films. It also produces what some consider an annoying level of noise when compared to other similar substrates.

 

Pre-Stretch Film
Pre-stretched film is expanded near its breaking point before it is wrapped onto rolls. This film does not necessitate as much energy as other stretch films to achieve the same wrapping force.
Pre-stretched film consumption often uses around 50% less than other stretch films, making for potentially extreme cost reductions.

 

Hay Baling Stretch Film
Hay baling stretch film is a multi-layer specialty stretch wrapping substrate made for wrapping baled rolls of hay. It is used primarily in the agricultural and farming industries.
Also known as silage stretch wrap, many types of these wraps feature LDPE (low-density polyethylene) formulations with oxygen barriers to keep your hay bales dry.

 

Hand Stretch Film
Hand stretch film is made exclusively to be wrapped by human labor manually. It is also known as hand film, hand stretch wrap, hand wrap, or manual pallet wrap.
It is commonly used by companies that wrap small volumes of products. Generally speaking, that would be companies that wrap less than 50 pallets per day.
The capabilities of manual stretch film must be continually checked against the various potential improvements that come with switching to a stretch wrapping machine.
Selecting the proper stretch application for your packaging line will improve efficiency and result in a more cost-effective production.

 

Color Stretch Film
Color stretch films were created to serve a very specialized niche area of packaging needs that other stretch film types cannot adequately service.
Color stretch film is perfect for warehouse color coding, international transportation, or dating inventory. Color stretch wrap is designed to be resistant to puncture.

 

UVI Stretch Film
Ultraviolet film is a stretch film with special light-discouraging additives that defend it from photographic degeneration in applications where wrapped products are kept outside and exposed to the elements.

 

VCI Stretch Film
VCI, or Vapor Corrosion Inhibitor stretch film, is made specifically for wrapping metal components, so they don't rust. This formulation prevents the oxidation of metals and is commonly used for packaging tools, metal pipes, and other metal products or materials.

 

Reinforced Stretch Film
Reinforced stretch films are thick films with especially strong formulations used to package and protect hefty loads for transportation and shipping. For example, this type of film is commonly used for palletizing and unitizing bricks and cinder blocks.

 

Vented Stretch Film
Vented stretch film is commonly utilized in applications where airflow and oxygen need to be available for packaged products. IE: wrapping pallets of wood, hot bakery items, etc.

 

NO Cling Stretch Film
No cling stretch film is used for packaging products such as carpeting so that the products being packaged can slide on and over each other without getting caught and tearing. There is also a variant of no-cling stretch film that has only one side that clings called one-sided cling stretch film.

 

Specialty Stretch Films
In some cases, specialized wrapping projects require the implementation of performance films with multiple layers with very high stretch capabilities. In addition, gauge reductions can be used, resulting in uncommon thicknesses of stretch films for similar applications.

 

Applications of Packaging Stretch Film
 

Palletized Boxes

This is the most common and widely seen use of stretch film. Boxes of different sizes and weights are stacked on a pallet and wrapped with stretch film to keep them together.

Buckets

Buckets of items such as paint, liquids, and dry goods are commonly wrapped with a heavier gauge stretch film to keep the contents in and from spilling.

Wire Reels

The film can be used to unitize reels together and it can also be used to prevent the wires from unwinding.

Canned Beverages

Another common use is to wrap around beverages. They are often stacked high and they are heavy, using the film keeps them together and from falling over with being stored and delivery purposes.

Furniture

Manufacturers and movers often use stretch film to secure the product, to keep it together, and to keep it from getting damaged while moving.

Feed and Seed

Pallet loads of feed and seed or often very heavy. Depending on the weight of the pallet shrink film can be used to keep it stable.

 

Process of Packaging Stretch Film
 
Stretch Wrap Film
 

Blown

The resin is melted and extruded through an annular die, it is air-cooled. This is a slower process but provides for higher cling quality. Blown film is not a consistent extrusion process, leading to inconsistencies across the film web. The cost of production is also higher due to the quantity that can be produced per hour.

 

Cast

The film is extruded through a slot die, then passed over cooling rollers. This makes the cooling process quick. Cast films are more consistent and have better performance characteristics. The cling quality is not as good as blown but more can be produced in an hour with lower costs.

Stretch Wrap Film
 

 

How to Store Stretch Wrap?
 

Short-Term Storage

Short-term film storage is the practice of storing wrapping film rolls for a short period before their use in the production process. This is a critical step in ensuring that the product remains properly protected during transit and storage, providing an additional level of protection for your valuable goods. Proper short-term film storage helps to keep your wrapping rolls in prime condition for use in the production process, preserving their integrity and minimizing potential waste due to spoilage or damage.


When storing wrapping film rolls, it’s important to ensure that they are stored away from direct sunlight and in a dry environment. Moisture can cause wrappers to degrade over time, leading to deformation and potential wastage. Additionally, the temperature of the storage area should be kept consistent – fluctuating temperatures can lead to premature aging of the roll and affect its performance when used for production. It’s also important to ensure that the storage space is well-ventilated, as this will help to keep the film rolls in good condition.

Long-Term Storage

When it comes to long-term storage, a wrapping film roll must be properly handled and stored. Firstly, the rolls should be inspected for any damage or contamination, which could cause the roll to degrade over time. Secondly, the rolls should be stored in an environment that is dark, dry, and well-ventilated. Exposure to light and moisture can reduce the quality of the film. Thirdly, it is important to ensure that the temperature stays within a range of 55°F and 77°F (13°C to 25°C). Finally, store wrapping film rolls away from chemicals, as this can also affect their performance when in use. With these precautions in mind, you can guarantee that your wrapping film roll will remain intact for long-term storage.

 

The Considerations for Buying

Performance
Selecting a stretch film that provides the right yield strength and performance for the loads being wrapped is crucial. The yield strength denotes the amount of stress a stretch film can withstand without permanently having plastic deformation. Prior to reaching the yield point a stretch film will elastically deform but return to its original shape once the stress is removed.

 

Overlapping
This is a technique for covering the top of your pallet using polythene top sheets. This protects your products and provides a downward force on the pallet load. When overlapping hand applied films, it is recommended users allow up to a 50% overlap. If using machine applied films, users should allow a 50mm overlap, regardless of the film width.

Banding

This refers to applying multiple wraps of stretch film to a particular area of a pallet to reinforce the load or band multiple units together.

Neckdown

This happens when a film loses its dispensing roll width and narrows down while being stretched. Neckdown reduces the coverage each wrap provides thereby making it likely that more wrap rotations and more film will be needed to wrap a load or pallet.

Time, Use and Cost Use

Hand wrapping is best suited for smaller or sporadic stretch film wrapping requirements. For example, if you are moving home or office, hand wrapping with stretch wrap will be more than adequate.
Alternatively, introducing machine wrapping may ultimately save time, resources, and packaging materials.

It is essential for product protection, minimizing losses, enhancing transportation efficiency, and reducing costs.

Q: How To Make Stretch Film?

A: The production of stretch films involves several stages. Here is an overview of how the stretch film is manufactured:
The initial stage is preparing the resin, typically polyethylene (PE).
Resin pellets are meticulously selected based on the stretch film’s desired properties, such as strength, flexibility, and transparency.
Extrusion: The resin pellets are delivered into an extruder machine, which melts and homogenizes them under temperature and pressure control.
The molten resin is then forced through a die to form a thin, continuous extrudate.
 
Cooling and Solidification: The molten resin is rapidly cooled and solidified as the extruded film travels through a cooling system.
This phase determines the film’s dimensions, thickness, and other physical properties.
 
Stretching and Orientation: Following solidification, the film enters a stretching unit consisting of a series of heated rollers or a specialized mechanism for stretching.
The film is stretched in both the machine (lengthwise) and transverse (crosswise) dimensions, which aligns the polymer chains and improves its strength and stretchability.
The stretched film is chilled in order to stabilize its molecular structure and enhance its dimensional stability.
Annealing, a controlled heating and cooling procedure, can also relax the film and improve its properties.
 
Winding and Slitting: The stretch film is wound onto large rolls as the final phase.
The coils’ width, thickness, and length can vary depending on the intended application.
The rolls can be slit into narrower widths if necessary to accommodate specific consumer requirements.

Q: Shrink Film and Stretch Film: What’s the difference?

A: In the packaging supplies world, stretch film and shrink film are two of the most mistakenly interchangeable words used when it comes to products. Although they sound similar, and both are types of plastic film, the difference between the two is actually huge. People often request samples, quotes, and orders of “shrink film” when they really mean stretch film — and it is easy to see why. Because packaging supply companies sell both, it can become confusing for both the client and the company to differentiate.
Also known as stretch wrap, stretch film is the clear plastic wrap applied by hand or machine to contain boxes and products on pallets. It acts as a safety net for pallets during the shipping, storing, and distribution process. Most stretch wrap is clear so the user can see what’s on the pallet for easy identification, scanning, and security, and it comes in many lengths, widths, colors, gauges, and types, depending on the need.
Stretch film is applied by hand (hand film) or by equipment (machine film). Hand film is usually smaller in width so that a person can manually hold the roll and wrap the stretch around the pallet. Hand film can come pre-stretched, which means the wrap has already been stretched to capacity as it sits on the roll. The user would not need to stretch it any further to wrap the pallet. Although this requires less output from the person applying the stretch film to the pallet, it also means that there is less film per roll, and it cannot contain as much as conventional, un-stretched wrap.
Machine film usually runs in a larger width to fit a machine wrapper, which can automatically wrap various pallet loads and sizes in a fraction of the time as a manual application. Some machine wrappers have an “arm” that rotates around the pallet, while others require the pallet to sit on a platform that spins while the stretch film is applied.
Stretch film can also be what’s called “blown” or “cast.” These terms refer to the way the stretch film was manufactured. These differences make a big impact on the usability and price of the film. Cast film is essentially a less expensive and more modern way to produce stretch film, although blown film has a variety of uses still today. Cast is perfectly clear, stretches easily, and does not stick to the hands. However, it can break easily if over-stretched, and does not shrink back to size as easily after stretching. Blown, on the other hand, is not crystal clear and is tacky to the touch, but it has a higher holding power and a greater resistance to tearing or breaking than cast. Use of one or the other depends on the pallet-wrapping needs of the user.
Shrink film is the tight plastic packaging that surrounds consumer goods like water bottles, soda cans, sporting goods, and pharmaceuticals. This film gets its name from the literal shrinking of the plastic film to package a product. It allows for bundles of products to be sold in one package, so you can buy a 24-pack of water bottles instead of 24 individual bottles of water. Shrink film also allows for increased security and protection, because it is easy to tell when a shrink-wrapped package has been tampered with. It can be printed and branded for optimized consumer awareness.
Shrink film typically comes in two types: Polyvinyl Chloride (PVC) and Polyolefin. PVC is considered a more “outdated” form of shrink film, although it is less expensive than its more modern counterpart. PVC is also not great for use with edible/consumable products, so for food and drink, Polyolefin is the way to go. Polyolefin is durable, has excellent clarity, and contains a high ability to shrink quickly and completely when heated.

Q: How to properly store stretch wrap?

A: To ensure the longevity and effectiveness of your stretch wrap solution, it's important to store it properly. Here are some tips for storing stretch wrap:
Keep it in a cool, dry place: Stretch wrap is made of plastic and can be sensitive to heat and humidity. It's best to store it in a cool, dry place to prevent degradation of the material.
Avoid direct sunlight: Exposure to sunlight can cause the stretch wrap to become brittle and lose its elasticity. To prevent this, store it in a place away from direct sunlight.
Use a stretch wrap dispenser: Using a stretch wrap dispenser can help you use the material more efficiently and prevent damage to the wrap. It also makes it easier to store the wrap neatly.
Keep it away from chemicals: Stretch wrap can be sensitive to chemicals, so it's important to store it away from any chemicals or solvents that could potentially damage it.
By following these tips, you can ensure that your stretch wrap remains in good condition and can be used effectively to protect your items during storage or transport.

Q: What Element In Stretch Film Makes It The Ideal Material For Wrapping?

A: Stretch Film is the highly elastic plastic material used to wrap products and secure them onto pallets. It is made from LLDPE and is the ideal material for wrapping and securing loads because of its flexibility. The film’s ability to stretch around corners of products, boxes, and pallets offers increased puncture and tear resistance as well as greater efficiency when applied appropriately. In order for stretch film to have these capabilities, makers of stretch film must add certain elements. Tackifier is an element used in the manufacturing process to add stickiness of the surface of the stretch film. Stickiness is an important trait in stretch film as it needs to be able to cling tightly to the other layers and maintain its adhesiveness as conditions change.
Stickiness is a great feature to have with stretch film, however most stretch wrappers that pre-stretch film, thin it out. As a result, there is less tackifier holding the film together. When there is not enough tackifier or the film is loaded wrong, the film unwinds from the pallet creating film tails. Film tails tend to drag on the ground, get caught in equipment, and more importantly, they unravel on loads and cause load holding failures. 

Q: Why use stretch films to wrap your goods?

A: Stretch film also known as stretch wrap is a plastic film that is highly stretchable and is used to wrap around items. There are different types of stretch films available in the market to meet the specific requirements of the stretch film wrapping needs based on type, performance, size as well as budget.
 
Stretch film delivers superior item protection
These films keep the product free of moisture, dust and dirt. The shipping damages are minimal. If UVI (Ultra Violet Inhibitor) stretch films are used it protects the item stored outdoors from ultra-violet rays. Apart from concealing the item contents it also reduces the instances of pilferage.
 
Stretch films are cost effective
Stretch film wrapping is a better alternative to strapping or heat shrink film. The machine, stretch wrap equipment, is less expensive compared to the other alternatives and also in terms of an amount of energy consumed.
 
Stretch wrapping is efficient
The item wrapped using stretch films can be easily scanned through optics. Since its easy to wrap, the productivity of the workers increases.
The stretch films can be recycled. There are many types of wrapping films to suit your specific requirements. Here we look at the various types of stretch films.

Q: What items can be packaged with Packaging Stretch Film?

A: Palletized Boxes – Probably the most common and easily recognized use of stretch film.  Boxes of a variety of sizes and weight arePalletized Boxes often palletized and wrapped using stretch film.
Buckets – Buckets of paint, liquids, and dry goods are commonly wrapped with a heavier gauged stretch wrap.
Wire Reels –  Film is used to unitize reels together and can be used to prevent wires from unwinding.
