Metal PE Printed Protective Film

Material

The base material is polyethylene (PE), usually LDPE (low-density polyethylene) or LLDPE (linear low-density polyethylene), and sometimes co-extruded film. PE has advantages such as softness, transparency (or translucency), non-toxicity, low cost, easy processability, and good chemical resistance.

Function

Its main role is to protect metal surfaces from scratches, abrasions, dust, oil stains, fingerprints, oxidation, and other damages during transportation, storage, processing (such as cutting, bending, stamping), and installation.

Such protective films usually need to have:

Appropriate adhesiveness: It can firmly adhere to metal surfaces (such as stainless steel plates, aluminum plates, galvanized plates, color steel plates, etc.) but can be easily peeled off when needed without leaving residual glue (low or medium adhesiveness is common). The adhesiveness needs to be selected according to the metal surface conditions (smooth, brushed, sandblasted, coated, etc.).

Good weather resistance: Resistant to a certain degree of ultraviolet rays (such as black-white film, milky white film).

Physical protection: A certain thickness and toughness to resist mechanical damage.

Stability: No chemical reaction (such as corrosion) with the metal surface during the protection period.
