PE Protective Films

PE protective films are primarily categorized by density (high, medium, and low), viscosity (slightly sticky, low, medium, high, and ultra-high), and color (transparent, blue, black, milky white, and textured). They can also be divided into adhesive-coated and adhesive-free types based on their structure. These films are based on PE plastic film, coated with pressure-sensitive adhesive or achieved through co-extrusion to create a certain degree of adhesion. They are widely used to protect metal, plastic, glass, and other surfaces from contamination and scratches.

Classification by Density :

PE protective films are based on specialty polyethylene (PE) plastic film and can be categorized by density as follows: High-density polyethylene (HDPE) protective film Medium-density polyethylene (MDPE) protective film Low-density polyethylene (LDPE) protective film .

Based on surface peel strength (viscosity), they are categorized as follows: Ultra-low-viscosity protective film (≤5g/cm): Easy to tear, leaving no adhesive residue, suitable for organic sheets, display screens, glass lenses, and more. Low-viscosity protective film (10-20g/cm): Suitable for steel mirror plates, silk screen printing, nameplates, etc.

Light-mist low-viscosity protective film and clear low-viscosity protective film: Suitable for process and end-use surface protection of sheet materials such as PC, PET, PMMA, and glass, and are widely used in the home appliance and optoelectronics industries. Medium-low-viscosity protective film (30-50g/cm): Suitable for stainless steel plates, ceramic tiles, stone, etc. Medium-viscosity protective film (60-80g/cm): Suitable for products requiring high adhesion.

Matte medium-viscosity and clear medium-viscosity protective film: Suitable for processing, molding, and end-use surface protection of PET hardened sheets and PMMA.

High-viscosity protective film (80-100g/cm): Suitable for surfaces requiring higher adhesion.

Ultra-high-viscosity protective film

High-temperature-resistant high-viscosity film: Suitable for surface protection of products requiring high-temperature molding processes such as luggage, helmets, and toys. Color Classification PE protective film comes in a variety of colors and can be customized to meet customer needs.

Common colors include: Semi-transparent or transparent: Most common, with light transmittance adjustable upon request.

Blue or green: Commonly used for electronics and panels.

Black: For light blocking and protection.

Ivory/creamy white: Used to distinguish specific products or provide shielding.
