High-Performance High-Barrier Antibacterial Stretch & Laminated Packaging Film
Our High-Barrier Antibacterial Stretch & Laminated Packaging Film is an advanced co-extruded composite material engineered for high-demand food preservation and industrial packaging applications. Combining multi-layer lamination (EVOH/PA/PE) with superior thermoforming stretchability, this film provides an exceptional barrier against oxygen, water vapor, and aroma loss while maintaining maximum mechanical strength.
Infused with food-contact safe antimicrobial technology, it actively suppresses bacterial proliferation on the film surface, extending shelf life for fresh red meat, processed poultry, cheese, and modified atmosphere packaging (MAP).
Key Technical Advantages
- ?️ Ultra-High Oxygen & Moisture Barrier: Incorporates EVOH and Polyamide (PA) barrier layers to achieve low oxygen transmission rates ($OTR < 2.0\text{ cm}^3/\text{m}^2\cdot24\text{h}\cdot\text{atm}$), locking in freshness and preventing lipid oxidation.
- ? Exceptional Thermoforming & Stretchability: Engineered for deep-draw thermoforming and flexible stretch packaging, offering high puncture resistance against sharp bones and hard food edges.
- ? Active Surface Antibacterial Guard: Built-in antimicrobial agents effectively inhibit common spoilage bacteria (such as Listeria, E. coli, and Salmonella), reducing microbial risk in cold-chain logistics.
- ⚡ High Thermal Seal Integrity: Outstanding seal-through-contamination performance ensures hermetic, leak-proof seals on automatic high-speed thermoforming and pouch-making machinery.
- ? Superior Optical Transparency: Crystal-clear clarity and high gloss present your packaged food with premium shelf appeal.
