Film di cellulosa a doppia tenuta - 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.
Ci concentriamo sulla ricerca e lo sviluppo, la produzione, la fabbricazione e la fornitura di vari film da imballaggio flessibili, ecologici e biodegradabili, tra cui BOPP, BOPET, BOPA, PE e film monomateriale riciclabili, e ci impegniamo a soddisfare le diverse esigenze di soluzioni di imballaggio del mercato.
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.
