Film a doppia tenuta in PLA - Keyful PLA-DS
• Derived from renewable corn, certified for industrialcomposting.
• Printability: Stable surface tension. Compatible with Flexo, Gravure, Offset, Screen, and UV printing. Supports premium hot foil stamping to deliver a sophisticated, high-end aesthetic.
• High transparency and gloss, excellent fold resistance, and strong mechanical properties
•Functionality: Inherent anti-static properties and excellent resistance to oils and grease.
The core value of Keyful PLA-DS lies in its dual-sided heat sealability and its ability to bridge the gap between high-end aesthetics and environmental compliance. For B2B buyers, this compostable heat sealable PLA film reduces the complexity of the supply chain by offering a single-material solution that simplifies the recycling and composting stream. With its 120% elongation at break and consistent coefficient of friction ($0.4/0.45$), it ensures mechanical reliability on high-speed conversion equipment, effectively lowering the total cost of ownership by reducing waste and downtime while significantly enhancing the brand’s sustainable profile.
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 PLA-DS is a high-performance PLA double seal film engineered from renewable corn starch, offering a fully certified industrial composting solution. Unlike standard films, this biodegradable double seal PLA film boasts inherent anti-static properties and superior grease resistance, making it an elite choice for high-speed automated lines. With a robust 40-micron thickness and balanced tensile strength (120 $MN/m^2$ in both MD/TD), it provides the structural integrity required for premium flexible packaging without compromising its eco-friendly DNA.
As a leading double sided heat sealable PLA film manufacturer, we offer a substrate with exceptional surface energy stability. It is optimized for sophisticated B2B branding, supporting Flexo, Gravure, and UV printing, alongside premium hot foil stamping for a high-end aesthetic. This eco-friendly double seal PLA ensures that sustainability doesn’t come at the cost of shelf appeal, providing high gloss and transparency that rivals traditional petroleum-based plastics while maintaining a much lower carbon footprint.
Applicazioni
- Flexible packaging industry: commonly used for mono layer bag making, including bags for garments, vegetables, components, toys, etc.; also suitable as a heat-seal layer in multilayer structures
