0.38mm transparent PET film Food Grade Packaging Material— The Preferred Choice for Food-Grade Thermoformed Eco-Friendly Packaging

This product is a transparent, recyclable RPET (Recycled Polyethylene Terephthalate) rigid sheet with a thickness of 0.4mm. Specifically designed for food-grade thermoformed packaging applications, it is widely utilized in scenarios such as fresh produce trays, bakery boxes, fruit containers, ready-to-eat meal boxes, salad cups, and pre-packaged supermarket containers. Manufactured using post-consumer recycled PET bottles (such as mineral water and beverage bottles) that meet stringent food safety standards, the material undergoes a sophisticated refining process involving deep cleaning, label removal, melt extrusion, and bi-axial calendering. The result is a material that seamlessly combines high transparency and excellent rigidity with sustainable, eco-friendly attributes.

As a food-contact material, this RPET rigid sheet strictly adheres to China's national standard for "Plastic Materials and Articles Intended for Food Contact" and has obtained relevant EU certifications. This ensures it is free from heavy metal residues and odor migration, making it safe for direct contact with a wide variety of dry and moist food products. With a light transmittance exceeding 91% and low haze, the sheet presents a crystal-clear and pristine appearance, effectively showcasing the fresh colors and premium quality of the packaged food to enhance its shelf appeal.

In terms of physical properties, the 0.4mm thickness strikes an optimal balance between providing sufficient stiffness and compressive strength while remaining lightweight and material-efficient—making it ideally suited for high-speed automated thermoforming production lines. The rigid sheet exhibits excellent thermoforming characteristics, featuring uniform heating and low molding shrinkage rates; it accurately replicates intricate mold details, resists edge cracking, and yields finished products with exceptional dimensional stability. Furthermore, the inherent properties of RPET material provide superior barrier performance (offering better resistance to oxygen and moisture vapor than PS or PP), thereby helping to extend the shelf life of food products.

Particularly noteworthy is its environmental value across its entire lifecycle: by incorporating 30%–50% recycled content (with select variants containing 30%–100% Post-Consumer Recycled [PCR] content), it significantly reduces the product's carbon footprint. Moreover, the product is fully recyclable after use, allowing it to re-enter a closed-loop recycling system—a feature that aligns perfectly with the sustainable packaging procurement requirements of global brands. In summary, the 0.4mm transparent, food-grade RPET rigid sheet not only meets high-performance packaging requirements but also assists enterprises in achieving their strategic goals of "plastic reduction, substitution, and recycling," making it an ideal material choice for transitioning toward a green and low-carbon supply chain.
