Multilayer PA/EVOH/PE High Barrier Thermoforming Plastic Roll Film Transparent Packing Materials for Food Grade Wrapping Film
EVOH (Ethylene-Vinyl Alcohol Copolymer) multi-layer barrier film represents a pinnacle in packaging technology. Primarily used as lidding film for various meal containers, its core function is to provide an exceptional barrier against oxygen and aromas. This prevents food oxidation, preserves freshness, and extends shelf life significantly. The multi-layer structure, often combining EVOH with polymers like PP or PET, balances superior barrier performance with necessary mechanical strength and sealability, making it an ideal and reliable sealing solution for modern food packaging.
✔ Unbeatable Freshness Lock - Superior oxygen barrier keeps food tasting fresh for longer.
✔ Aroma Guardian - Prevents flavor transfer and locks in the original taste.
✔ Extends Shelf Life - Significantly slows down spoilage, reducing food waste.
✔ For Hot & Cold Meals - Reliable performance for both microwave reheating and refrigerator storage.

Safety First (Metal Detectable & Food-Grade):
Unlike aluminum foil, our EVOH barrier film passes through metal detectors seamlessly, ensuring 100% food safety compliance on your production line. Made from food-grade materials with BPA-free certification, this high barrier lidding film eliminates contamination risks while maintaining superior protection against oxygen and moisture.
Design Flexibility & Customization:
We offer comprehensive customization for your thermoforming film needs:
Custom logo printing and embossing
Variable thickness (50-150 microns)
Tailored peel strength (easy-peel to permanent seal)
Optical properties (high-clarity or matte finish)
This flexibility ensures optimal performance for every unique meal box application, from simple snack pots to complex multi-compartment trays.
Cost Efficiency & Sustainability:
Being significantly lighter than traditional aluminum and rigid containers, our EVOH film reduces shipping weights by up to 30% and lowers your carbon footprint. The multi-layer structure uses less material while delivering superior barrier performance, making it a cost-effective and eco-friendly choice for modern food packaging.
Superior Barrier Performance:
The EVOH core layer provides exceptional oxygen barrier properties (<1.0 cc/m²/day), dramatically extending shelf life and preventing food oxidation. Combined with excellent aroma retention, this high barrier packaging film keeps your products fresh and flavorful from production to consumption.

Ready-to-Eat Meals:Ideal for sealing microwaveable meal trays, our EVOH lidding film preserves freshness and flavor during storage and reheating. The superior oxygen barrier prevents spoilage in prepared salads, pasta dishes, and protein-rich entrees. Perfect for modified atmosphere packaging (MAP) applications that extend shelf life significantly.
Fresh Produce & Salads:Extends shelf life for chilled food containers by creating an optimal modified atmosphere (MAP) barrier. Our transparent high barrier film maintains product visibility while protecting delicate greens, cut fruits, and vegetables from oxidation and moisture loss. The breathable seal prevents condensation buildup.
Premium Food Delivery:Ensures leak-proof, secure, and quality-preserving seals for gourmet and hot/cold delivery meal boxes. The heat-seal EVOH film withstands transport vibrations and temperature fluctuations, keeping sauces contained and meals presentable from kitchen to customer's door.
Dairy & Deli Containers:Protects sensitive products like yogurt, dips, and sliced meats from oxidation and odor transfer. The aroma barrier properties of our PA/EVOH/PE film prevent cross-contamination of flavors, ensuring each product maintains its distinct taste and freshness profile.
