HSQY Multi Layer PA/EVOH/PE High Barrier Thermoforming Plastic Roll Film Transparent Packing Materials
The performance stems from advanced co-extrusion technology. Typically, EVOH is sandwiched between outer layers of polyolefins like PP or PE. The outer layers provide durability, puncture resistance, and good heat-seal characteristics, while the internal EVOH layer delivers the barrier. This synergistic structure allows for customization of thickness and properties, tailoring the film for specific meal box materials, contents, and storage conditions.
✔ Crystal Clear Visibility - Showcases your food while protecting it (also available in opaque finishes).
✔ Leak-Resistant Seal - Secure, strong seal prevents spills and leaks in transit.
✔ Customizable Design - Tailored peel strength, layers, and barrier levels for your specific product.
✔ ProductLightweight & Efficient - High performance in a thin, resource-efficient gauge.

Safety First (Metal Detectable):
Passes through metal detectors, ensuring 100% food safety compliance on your production line. Unlike aluminum foil laminates, our EVOH film allows for metal detection, eliminating the risk of metal contamination.
Perfect Seal for PET Substrates:
Our EVOH barrier film is specifically engineered to bond securely with PET Food Tray bases. It provides a hermetic seal that prevents leakage and maximizes the barrier properties of the PET material, ensuring your products stay fresh and secure during transit.
Design Flexibility & Printability:
We offer custom logo printing and high-clarity finishes. The crystal-clear transparency of this film showcases the vibrant colors of your food, enhancing the visual appeal of your PET Food Tray packaging on retail shelves.
Cost Efficiency & Microwave Safety:
Being lighter than traditional aluminum materials, it reduces shipping weights and carbon footprint. Crucially, it is microwave-safe, allowing consumers to reheat meals directly in the pet food storage container (made of PET or PP) without removing the film (depending on venting), offering unmatched convenience.

Ready-to-Eat Meals:Ideal for sealing microwaveable meal trays. The high oxygen barrier of our EVOH sheet dramatically extends shelf life. It is the perfect lidding solution for PET Food Tray containers used in supermarket ready-meal sections.
Fresh Produce & Salads (MAP):Extends shelf life for chilled food containers by creating an optimal modified atmosphere (MAP) barrier. The film maintains the crispness of salads and prevents oxidation, keeping the product fresh inside the pet food storage container (high-clarity PET box) for days longer than standard films.
Premium Food Delivery:Ensures leak-proof, secure, and quality-preserving seals for gourmet and hot/cold delivery meal boxes. The strength of the PA/EVOH/PE structure prevents puncture, making it reliable for delivery services using rigid PET Food Tray packaging.
Dairy & Deli Containers:Protects sensitive products like yogurt, dips, and sliced meats from oxidation and odor transfer. The aroma barrier ensures the original taste is locked in, whether packed in PS cups or pet food storage container formats.
● CPET Lidding Film:
Anti-fog & Easy-peel. Formulated to bond perfectly with CPET trays.
From manual table-top sealers to fully automatic lines.
● Paper Sleeves:
Custom printed branding sleeves for retail display.
Yes. The EVOH barrier layer dramatically reduces oxygen ingress (OTR < 1.0 cc/m²/day), which is the main cause of spoilage. When paired with a rigid base like a PET Food Tray, it creates a high-barrier environment that can double or even triple the shelf life of sensitive products like salads and proteins
