PET packaging combines high oxygen barrier properties with excellent transparency, offering long-lasting performance and environmental durability.
Runpacet PET oxygen barrier/absorber employs a multi-tiered protection system through physical barriers, chemical absorption, and molecular structure modification. The core challenge lies in balancing high barrier performance with optical clarity while ensuring compatibility between long-term effectiveness and environmental resilience. Particularly in applications such as fresh food preservation, high-end electronics moisture protection, and new energy battery encapsulation, high-performance oxygen barrier materials are becoming pivotal for industrial advancement. Concurrently, ongoing attention must be paid to regulatory safety requirements concerning nanomaterials and chemical additives.
Market applications include oxygen-barrier packaging for food, beverages, cosmetics, pharmaceuticals, and personal care products, encompassing containers, films, and sheets. Examples of beverage containers include bottles for juices, sports drinks, and beer, where oxygen can adversely affect flavor, aroma, efficacy (preventing vitamin degradation), and color stability. These can be processed into both single-layer and multi-layer rigid containers.
PET sheets, films, and rigid packaging also include food trays. Examples of food tray applications include dual-purpose oven-safe trays or refrigerated food trays, both of which rely on primary packaging (lids or films) to maintain the freshness of contents by preventing oxygen ingress, thereby preserving product functionality and complying with FDA regulations.
