Cellulose Double Seal Film-Keyful CP-DS

•Eco-Sourcing: Derived from renewable wood pulp. Certified for industrial and home composting.
•By adding a small amount of PVDC to optimize moisture and gas barrier properties, it enables simpler and lighter packaging structures, helping to extend and maintain the shelf life of packaged products.It offers high strength, excellent toughness, high transparency, and strong tear resistance.
•Dual-sided heat-sealable capability.
•Resistant to moisture absorption.

The core value of Keyful CP-DS lies in its exceptional sustainable performance throughout its entire lifecycle and its industrial-grade quality. This material achieves a thickness of 27 ± 2 μm combined with a heat resistance of 139°C. This film not only addresses the common pain points of biodegradable materials, such as being “fragile and difficult to seal,” but also provides wholesale/distributor customers with a balance between simple packaging structures and long shelf life. In the global context of “de-plasticization,” it is not only a compliant choice that meets legal regulations but also a premium solution for enhancing a brand’s green competitiveness.

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 CP-DS series cellulose double seal film utilizes renewable wood pulp as its raw material, perfectly balancing environmental performance with industrial practicality. As a high-performance, compostable double seal cellulose film, it incorporates a precisely proportioned PVDC coating during production. This coating not only significantly optimizes water and oxygen barrier properties but also achieves a reduction in material usage by simplifying the packaging structure. Its high transparency and excellent tear resistance provide products with exceptional visual presentation and physical protection, making it an ideal choice for the modern flexible packaging industry’s transition to eco-friendly double seal cellulose.

As a manufacturer of double-sided heat-sealable cellulose film, we understand the efficiency requirements of automated industrial packaging. This product features double-sided heat-sealing properties, significantly broadening the range of applicable bag-making and wrapping processes. Its excellent moisture resistance ensures physical stability in complex storage environments, and combined with a heat resistance range of $139\pm2$°C, it can be adapted to various high-speed automatic filling production lines. We have set a new benchmark for global suppliers of biodegradable heat-sealable cellulose film, committed to providing brand owners with customized solutions that comply with environmental regulations and enhance shelf life quality.

    Under standard home or industrial composting conditions, our film typically biodegrades within 180 days, ultimately converting into carbon dioxide and water, meeting international standards such as EN 13432.

    Double-sided heat sealing allows for bonding in any direction in folded packaging or complex bag types, effectively reducing downtime for adjustments and is compatible with three-side seal, back seal, and stand-up pouch making processes.

    Our formula is precisely calculated, with a very low PVDC addition, which enhances the water vapor barrier (WVTR of 5g/m²·24h) without compromising the overall compostable certification of the cellulose-based substrate.

    Its MD tensile strength is as high as 200 $MN/m^2$, providing excellent tensile rigidity. By adjusting the coefficient of friction (0.23), smooth film travel on guide rails and forming cylinders is ensured.

    We support slitting into various thicknesses, such as 27 microns, and can provide specialized treatments for printing coatings and surface wet tension (36/38 dyne/cm) to match your printing ink system.

    Although the unit price is slightly higher than traditional BOPP, its compostable premium can help brands enter high-end supermarkets and avoid plastic taxes. Its high yield of 28.6 $m^2/kg$ also optimizes the unit packaging cost.

    Its heat resistance point reaches 139°C, and the heat-sealing layer maintains high sealing performance while exhibiting good cold resistance, making it suitable for multi-temperature zone supply chain logistics.

    Yes, we provide roll stock samples for large flexible packaging factories and dispatch technical teams to assist in debugging heat-sealing pressure and temperature parameters.
