As the food preservation industry advances toward standardization and sustainability, tray lidding film has become the core packaging format for cooked food, chilled meat and fresh-cut fruits & vegetables. Most modified atmosphere packaging (MAP) lidding films available today use multi-layer dissimilar composite manufacturing, which meets basic preservation needs yet carries inherent technical drawbacks in recyclability, stability and safety. New single-material MAP lidding film overcomes the limitations of traditional products, striking a balance between preservation performance and eco-friendliness.

Conventional MAP Lidding Film — Inherent Drawbacks

Conventional commercial MAP lidding films feature multi-layer composite structures, bonding different polyolefin materials with chemical adhesives. Some variants add barrier coatings and vacuum metallization layers to boost preservation effects. Though this widely adopted manufacturing method is industry-standard, mixed-material construction creates multiple disadvantages. Adhesives and functional coatings cannot be separated, making post-consumer sorting and recycling extremely difficult with minimal recycling value. Furthermore, multi-layer composite production involves cumbersome workflows that raise energy consumption, while introducing risks including solvent residue, interlayer delamination and uneven thickness. Long-term use may lead to degraded sealing performance and shortened shelf life, posing potential food safety risks.

Single-Material Solution — Recyclable & Clean

In contrast to traditional composite processes, Zhejiang Zhongda's self-developed single-material MAP lidding film uses an original integrated molding technology that optimizes film structure at the production source to eliminate core pain points of conventional alternatives. For recycling compliance, its uniform molecular composition enables full recyclability without complex purification or separation steps, compatible with standard plastic recycling systems. Recycled material retains stable performance, lowering environmental pressure from packaging waste and aligning with food manufacturers' ESG compliance and sustainable production targets.
