BOPLA Acrylic Adhesive Protective Film (High Gloss & Clarity) — Keyful PLA-AP

-Dérivé de maïs renouvelable, certifié pour le compostage industriel.

•Uniform coating, no wrinkles, tearing, or particles

•High transparency, printable

•Customizable adhesion

•Bubble-free, anti-yellowing, no rebound, no adhesive transfer

Keyful PLA-AP combines the stable adhesion and transparent appearance of compostable-compliant BIO-PLA with BOPLA acrylic adhesive film. The uniform coating minimizes wrinkles and particles, reduces bubbles, and resists yellowing, while emphasizing residue-free removal. It is suitable for die-cutting, slitting, and high-volume protection. Targeted at appearance-sensitive applications in 3C, metal, and home appliance industries, it reduces scratches, contamination, and rework, improving delivery consistency and efficiency.

Nous nous concentrons sur la recherche et le développement, la production, la fabrication et la fourniture de divers films d'emballage flexibles, respectueux de l'environnement et biodégradables, y compris les films BOPP, BOPET, BOPA, PE et les films mono-matériaux recyclables, et nous nous engageons à répondre aux divers besoins du marché en matière de solutions d'emballage.

Keyful PLA-AP is a BOPLA acrylic adhesive film based on a BIO-PLA substrate derived from renewable corn and is industrially compostable certified, making it suitable for customers with compliance and delivery requirements. The coating is uniform, free of wrinkles, tears, and particle interference, and is compatible with die-cutting/slitting continuous production.

The transparent acrylic protective film offers high transparency and a clear appearance, and is printable. Adhesion can be customized to meet requirements, featuring bubble-free application, anti-yellowing properties, low rebound, and no adhesive residue transfer. The material and PSA system are stable within the range of -20 to 80°C, which contributes to the consistency of packaging protection.

Applications

Die-cutting industry: protection for electronic screens, plastics, high-end hardware, metals, and home appliance surfaces.

PC/Plastic Panel & Protective Film Lamination Factories: Used with die-cutting and slitting for secondary protection, reducing rework caused by particles and wrinkles.

High-End Hardware & Metal Manufacturing: Used for masking and protection of metal/plastic component surfaces and as a buffer before subsequent mounting, improving batch appearance consistency.

Appliance Panel & Component Packaging Companies: Provides a transparent protective layer during packaging, handling, and warehousing, facilitating inspection and quality control retention.

    It’s both: As a Transparent acrylic protective film, it prioritizes high transparency while also being printable, making it suitable for processes requiring information presentation on the protective layer (subject to customer ink/parameter testing).

    Customizable adhesion is supported. Because your application scenarios differ (surface material, application time, removal method), the adhesive strength can be selected within a range and verified with samples based on your target.

    This system emphasizes bubble-free application, anti-rebound properties, and controlled no adhesive transfer, designed to reduce adhesive residue and contamination issues after application.

    The product description includes anti-yellowing properties to reduce the risk of appearance degradation during storage and transportation; the final effect is still influenced by storage conditions and packaging structure.

    The temperature range covers -20 ~ 80°C, suitable for common production, storage, and logistics environments; it’s recommended to inform us of special extreme conditions in advance for verification.

    The key is a uniform coating to minimize typical defects such as no wrinkles / no tearing / no particles; the specifics still need to match the die, die layout, and speed parameters.

    This solution includes a transparent PET release film (release layer parameters are provided) to ensure controllable application/peeling; the existing composite/lamination line you have will be the benchmark for confirming the structure during implementation.

    It’s significantly valuable for customers who need environmental compliance narratives, supply chain audits, or labeling requirements. We recommend you provide your end-use and compliance material requirements so we can assist in preparing the necessary project implementation materials and aligning batch documents.
