Takeout packaging has poor oil resistance and is prone to leakage; retail display packaging lacks environmental labeling, affecting brand image; traditional paper packaging loses strength rapidly after absorbing water, failing to meet the packaging requirements for high-temperature fried foods.
Adopting food-grade waterproof and oil-resistant coating technology (certified according to GB4806.7-2016), combined with a dual drying system to achieve rapid shaping in 180 seconds; developing high-temperature resistant (120℃) pulp molded lunch boxes to meet the direct packaging needs of fried foods; supporting carbon footprint label certification, with each package indicating the source of raw materials, energy consumption data, and degradation cycle.
A chain restaurant brand adopted Chunyang oil-resistant lunch boxes, reducing its annual plastic usage by 3,000 tons and achieving a packaging recycling rate of 95%; tests showed that the packaging for 120℃ fried foods retained 90% of its original strength after 30 minutes, demonstrating three times the oil resistance of traditional paper packaging, and obtaining "Green Catering Packaging Certification".
