Introduction
PE (Polyethylene) protective film is a highly versatile, cost-effective material designed to safeguard surfaces during manufacturing, transportation, installation, and storage. Composed of low-density polyethylene (LDPE) or linear low-density polyethylene (LLDPE), this self-adhesive film provides temporary protection against scratches, dust, moisture, and abrasion while maintaining excellent optical clarity and conformability.

PE Release Film Coating employs a plasma-enhanced chemical vapor deposition (PECVD) process to deposit a fluorinated silica-carbon hybrid nanolayer with a surface energy of 18-22 mN/m, achieving ultra-low adhesion (<5g/25mm) and exceptional chemical resistance to isopropyl alcohol (IPA) and PCB flux residues, while PE Release Film for Electronics Industry integrates a conductive carbon black-dispersed PE matrix with a gradient-structured release coating (surface resistivity 10⁶-10⁹ Ω/sq) to enable electrostatic discharge (ESD) protection during SMT component handling and controlled peel strength for flexible printed circuit (FPC) lamination processes, ensuring compatibility with both rigid PCB manufacturing and emerging wearable electronics applications.
