Attribute	Description	Reference
Material Composition	Multi-layer co-extruded structure (e.g., PP/EVOH/PP or PET/AL/PE), with an inner heat-sealable layer and EVOH/aluminum barrier for leak prevention.	1 8
Leak-Proof Design	Precision heat-sealing layer (e.g., LLDPE) ensures airtight seals on cup rims, preventing spillage during transport or handling. Compatible with automatic sealers.	1 6
Temperature Resistance	Stable performance across -40°C (freezing) to 80°C (hot-fill), maintaining seal integrity and flexibility without brittleness or delamination.	6 9
Barrier Properties	Ultra-low OTR (≤0.8 cm³/m²day) and WVTR (≤1.5 g/m²day) protect against oxidation and moisture, preserving bubble tea freshness.	8 9
Optical Performance	High transparency (≥90% visible light transmittance) with optional anti-fog coating to maintain clarity in icy beverages.	6 9
Safety Compliance	FDA 21 CFR, EU 10/2011, and LFGB certified for direct food contact; BPA-free and migration-tested for heavy metals.	8 9
Processing Features	Compatible with VFFS machines and automated cup sealers; heat-sealable at 120-160°C with fast curing time (≤2 sec).	1 6
