Protective Film Adhesion Levels: Which PE Film is Right for Your Material

PE Temporary protective films are categorized by thickness, color, adhesive Strength, and applications, allowing users to select the most suitable type for their products. Below is a guide on the adhesion classifications of PE Temporary protective films:

Adhesion Levels of PE Temporary Protective Film

1. Ultra-Low Adhesion (Static Film)
   • Peel Strength: ≤5g/cm
   • Tensile Strength: >400
   • Features: Easy to apply and remove, leaves no residue.
   • Applications: Suitable for organic panels, instruments, display screens, glass, and plastic lenses. They are commonly referred to as “static film” in the market.
2. Low Adhesion (Static Film)
   • Peel Strength: 10-20g/cm
   • Tensile Strength: >400
   • Features: Stable adhesion, excellent attachment and peel-off performance, residue-free.
   • Applications: It is ideal for steel mirror plates, titanium, smooth plastic plates, silk printing, and nameplates. It is often known on the market as “static film.”
3. Medium-Low Adhesion Protective Film
   • Peel Strength: 30-50g/cm
   • Tensile Strength: >400
   • Features: Stable adhesion, strong attachment, excellent removal properties, leaves no residue.
   • Applications: Used for melamine furniture boards, stainless steel plates, tiles, marble, and synthetic stone.
4. Medium Adhesion Protective Film
   • Peel Strength: 60-80g/cm
   • Tensile Strength: >400
   • Features: Stable adhesion, high attachment strength, excellent peel-off capability, residue-free.
   • Applications: Suitable for fine textured frosted plates and general difficult-to-adhere surfaces.
5. High Adhesion Protective Film
   • Peel Strength: 80-100g/cm
   • Tensile Strength: >400
   • Features: Stable adhesion, strong attachment, excellent removal properties, no adhesive residue.
   • Applications: Commonly used for fine textured frosted boards, aluminum-plastic panels, and challenging plastic plates.
6. Ultra-High Adhesion Protective Film
   • Peel Strength: >100g/cm
   • Tensile Strength: >400
   • Features: Extremely high adhesion, uses water-based acrylic as a pressure-sensitive adhesive, easy to apply and remove but may leave some residue.
   • Applications: Suitable for rough-textured aluminum boards and other hard-to-stick materials.

Each PE temporary protective film category is crafted to meet specific needs, ensuring surfaces remain undamaged and residue-free throughout use.
