High Temperature CPP Protective Film-Frosted Clear Cast Film for Light Guide Plate Automotive Parts
Our High-Temperature CPP Base Film is a premium cast polypropylene substrate manufactured on advanced imported production lines to deliver superior surface flatness, optical clarity, and robust heat resistance up to 150°C for 1 hour. Engineered for demanding industrial and electronics processing, this high-performance CPP release and protective base film ensures dimensional stability under elevated temperatures.
It is widely applied in the processing and surface protection of PMMA, PC, ABS, and PVC sheets, PET materials, rigid plastic substrates, high-gloss injection-molded plastics, precision electronic components, touchscreens, and optical mirror finishes.

Our industrial-grade high temperature resistant CPP (Cast Polypropylene) protective film is a general-purpose, low-tack, multi-layer protective film featuring stable adhesion and minimal change in tack over time and it is engineered for temporary surface protection of delicate smooth substrates, metal sheets, plastic panels(PVC sheets, PET sheets, acrylic sheets), PC, glass, and electronic components during manufacturing, processing, storage, and transit.
Available in both self-adhesive and non-adhesive options, it provides excellent optical clarity, puncture resistance, and stable dimensional integrity. The CPP film shields sensitive surfaces from scratches, dust, chemical splashes, and abrasion. Formulated for clean removal without leaving adhesive residue or ghosting, it delivers a reliable, cost-effective surface protection solution for global industrial applications.
Features
High optical transparency allowing easy visual inspection of underlying substrates.
Excellent puncture and tear resistance for reliable protection during processing and transport.
Residue-free removal ensures clean surfaces after film stripping.
Controlled, stable peel strength for smooth manual or automated lamination.
Good heat and moisture resistance suitable for diverse manufacturing environments.
Available in both self-adhesive (acrylic/rubber glue) and non-adhesive static/co-extruded options.
Outstanding dimensional stability with minimal elongation under continuous tension.
Environmentally friendly, RoHS-compliant polypropylene material with full recyclability.
Key Applications of CPP Film:
- CPP surface protective film features stable peel strength, excellent weather resistance, and high cleanliness (free of gel particles); As a non-adhesive coated protective film, it leaves no adhesive residue upon removal.
- It is suitable for application onto substrates such as polyester (PET), polycarbonate (PC), or acrylic (PMMA), as well as various composite materials. Applications include barrier materials for new energy vehicle power batteries, touchscreen glass, ITO-sputtered surfaces, and light guide plates.
- It is used in the upstream manufacturing of optical and electronic materials in both roll and sheet formats.

FAQ
Q1: What is the main difference between self-adhesive and non-adhesive CPP protective film?
Self-adhesive CPP film incorporates a solvent or water-based adhesive layer to bond securely with rough or glossy surfaces. Non-adhesive CPP film relies on static electricity or co-extruded self-tack resins, making it ideal for smooth, high-gloss surfaces that require zero risk of chemical or glue transference.
Q2: Does the self-adhesive CPP film leave glue residue after removal?
No. Our self-adhesive CPP film uses high-cohesion acrylic adhesives engineered specifically for temporary protection. It offers stable peel adhesion and removes cleanly without ghosting or leaving residue, even after extended surface contact.
Q3: Can you supply custom widths, roll lengths, and die-cut shapes?
Yes. We offer complete converting services including slitting to exact widths, rewinding to targeted roll lengths, and custom precision die-cutting according to your technical drawings.
Q4: Is the CPP protective film compatible with automated lamination machinery?
Yes. The film features balanced unwinding tension and high tensile strength, ensuring smooth, bubble-free application on high-speed continuous industrial lamination lines.
Q5: Are samples available for testing before bulk production?
Yes. We provide complimentary A4 sheet samples or small test rolls for clients in the USA, Europe, Southeast Asia, and globally to verify adhesion and surface performance.
