AI Technical Summary
Existing biodegradable packaging films cannot simultaneously meet the requirements of heat resistance, barrier properties, interlayer bonding strength, and easy-to-open properties under high-temperature cooking conditions of 121℃. Furthermore, traditional petroleum-based plastic packaging materials are difficult to degrade, causing environmental pollution.
The membrane adopts a three-layer co-extruded composite structure, including a heat-resistant layer, a barrier layer, and a heat-sealing layer, which are respectively composed of high heat-resistant polylactic acid, copolyester, and polybutylene succinate-adipate. By introducing rigid benzene rings and ionic groups, the regularity of the molecular chain is improved. Combined with nano-reinforcing agents and reactive compatibilizers, chemical bonds are formed to ensure the stability and ease of peeling of the membrane.
It maintains dimensional stability and mechanical properties under 121℃ cooking conditions, has excellent barrier properties, achieves a clean and easy-to-peel consumer experience, meets food safety standards, and is completely biodegradable with no environmental pollution.
