Keyful Cellulose High-Barrier Metallized Film – CP-BM, derived from renewable wood fibers, is certified for industrial and home composting, making it environmentally friendly while offering excellent barrier properties. It provides superior protection against humidity, moisture, and oxygen, with a high-gloss, wrinkle-resistant surface, making it a premium alternative to PET metallized film.
The film possesses inherent antistatic properties and strong resistance to grease/oil. With an oxygen transmission rate of 3 cc/m²·d and a moisture vapor transmission rate of only 16, it enhances the freshness and stability of food packaging. Its wide range of applications includes use as an intermediate barrier layer in flexible packaging for tea bags, coffee, and other food products. Combining environmental protection with high sealing performance, it is an ideal choice for commercial customers seeking a sustainable supply chain.
Applications
•Flexible Packaging Industry: Used as an intermediate barrier layer in tea bags, coffee packaging, and food packaging.
•Sealing & Temperature Resistance: Stable sealing strength with a sealing temperature range of 120–160°C, suitable for various heat-sealing processes, ensuring consistency in large-scale production.
•Sustainable Supply Chain: The material is derived from renewable fibers, with industrial/home compostability certification, facilitating corporate-level environmental advocacy and compliance commitments.
•Compatibility & Process Friendliness: Exhibits good compatibility with common coating, printing, and lamination processes, facilitating the coordinated optimization of customized thickness, barrier levels, and surface treatment solutions.
