Keyful cellulose compostable High barrier metallized film manufacturers & supplier, with excellent oxygen/water barrier, anti-static and oil-resistance properties, derived from compostable wood pulp, supporting customized thickness, sealing temperature and barrier levels, helping to build environmentally friendly and efficient flexible packaging solutions.

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 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.

    High barrier properties (oxygen permeability 3 cc/m²·d, water permeability 16), can replace PET metallized film, and is derived from renewable wood pulp, with antistatic and oil-resistance properties, complies with composting certification, and helps improve freshness and packaging stability.

    We can provide customized thickness ± tolerance and corresponding barrier level solutions according to your product line and packaging requirements to ensure compliance with process lines and performance indicators.

    This film has stable sealing strength in the 120–160°C sealing temperature range and is compatible with common heat sealing machine models; if you have specific equipment, please provide the parameters, and we can provide a connection plan.

    Small batch samples are provided for process evaluation, and we can assist in establishing process parameter tables, sealing strength tests, oxygen and water permeation detection, and other data to accelerate prototyping and scale-up.

    The material is certified for industrial and home composting, complies with relevant standards, and can support sustainability claims and compliance requirements for packaging materials.

    Based on production line capacity, transportation distance, and batch level, we can provide material selection, thickness gradient, complete process solutions, and cost-performance trade-off analysis to help achieve cost control and performance compliance.

    After confirming specifications and capacity, a clear production and delivery schedule can usually be provided to support scheduling and delivery commitments for batch orders.

    We provide on-site or remote process training, sealing parameter optimization guidance, quality control solutions, and process improvement suggestions to help customers improve stability and production line efficiency.
