PLA Window View Film High Gloss & Clarity-Keyful PLA-WV
•Derived from renewable corn, certified for industrial composting.
•Excellent barrier properties: resistant to moisture, water, and oxidation, with fold resistance and high gloss..
•Functionality: Inherent anti-static properties and excellent resistance to oils and grease
•Can be customized according to customer requirements, such as scratch-resistant performance and double-sided anti-fog properties.
PLA-WV combines renewable corn-derived materials with a high-clarity, high-gloss window, offering resistance to water vapor, oxidation, static electricity, and grease. It also supports customization for scratch resistance and anti-fog properties. For folding carton window applications, it can replace PET/plastic window patching, providing a sustainable, environmentally friendly, degradable, high-transparency, and visible window packaging solution.
We focus on the research & development, production, manufacturing, and supply of various flexible, environmentally friendly, and biodegradable packaging films, covering BOPP, BOPET, BOPA, PE, and recyclable single-material films, and are committed to meeting the diverse packaging solution needs of the market.
Keyful PLA-WV is a PLA window film for window packaging, made from renewable corn and certified for industrial composting, meeting compliance procurement needs for biodegradable window film PLA. The film surface boasts high transparency and gloss, combined with water vapor and oxidation barrier properties, enhancing the stability of the window area during humid conditions and transportation.
It also exhibits natural anti-static, oil resistance, and durable folding performance. Supports project-based customization (e.g., improved scratch resistance, double-sided anti-fog) and can replace PET/plastic window patches to create a compostable window film solution for packaging.

Applications
Food Packaging Plants (Bread/Bakery/Deli): Used for carton window patching, allowing consumers to directly see the contents and improve shelf recognition.
Fruit and Refrigerated Fresh Food Box Manufacturers: Provides better anti-oxidation and moisture resistance support in the transparent window area, reducing window fogging.
Gift and E-commerce Packaging Customization Factories: Uses PLA transparent window film for high-transparency appearance and exquisite display, satisfying eco-friendly selling points.
Carton/Folding Box Color Printing and Post-Processing Service Providers: Can customize slitting solutions according to the customer’s pace and specifications before window lamination, improving the consistency of die-cutting and lamination.
