For surface protection, PE film is best for most metal and panel applications (flexible, clean removal, cost-effective), PET film excels in high-temperature and electronics applications, and PVC film suits deep-draw forming and heavy corrosion protection but carries environmental concerns. This comparison helps you choose the right material for your specific application.

| Common uses | Metal sheets, panels, glass, plastics | Deep drawing, corrosion wraps | Electronics, high-temp processes |
PE Film: The General-Purpose Workhorse
PE protective film dominates the metal processing and construction panel industries—and for good reason. It is soft and conformable, laminates easily at room temperature, and removes cleanly with water-based acrylic adhesive systems. Its low cost per square meter makes it economical for high-volume applications like stainless steel coils, aluminum profiles, and APCP (aluminum composite) panels.
Choose PE when: you are protecting metal sheets, coils, glass, painted panels, or plastic sheets at room temperature, and you need clean removal at the lowest cost. This covers roughly 80% of industrial surface protection scenarios.
PVC Film: For Forming and Corrosion Protection
PVC film is thicker and more elastic than PE, which gives it two advantages: it survives deep-draw forming processes (film stretches with the metal without tearing) and it provides superior barrier properties for corrosion protection during ocean shipping. However, PVC contains chlorine, which creates disposal issues and restricts its use in some markets and applications (notably electronics and anything RoHS-relevant).
Choose PVC when: the protected part will be mechanically formed after filming (deep drawing, stamping), or when long-term corrosion protection during harsh shipping is required and environmental regulations allow it.
PET Film: For Heat and Precision
PET film offers the highest tensile strength and temperature resistance of the three. In surface protection, it is used where heat is involved—powder coating lines, hot-forming processes—or where extreme cleanliness matters, such as optical films and electronics manufacturing. Its rigidity and cost limit its use for ordinary metal protection.
Choose PET when: the film must survive high temperatures (above 100°C), the protected surface is high-value electronics or optics, or you need very thin film with high strength.
Decision Guide by Application
| Your Application | Recommended Film | Why |
|---|---|---|
| Stainless steel / aluminum sheets & coils | PE | Clean removal, low cost, right flexibility |
| Glass & acrylic sheets | PE | Low tack prevents residue on smooth surfaces |
| Deep-drawn parts (stamping, forming) | PVC | Stretch without tearing |
| Ocean shipping corrosion protection | PVC | Superior moisture barrier |
| Electronics / display surfaces | PET | Cleanliness, thin profile |
| High-temperature processes (100°C+) | PET | Heat resistance |
| Construction panels (APCP, painted) | PE | Cost-effective, easy lamination |
