Integrated Thickened Sealing Edge Mold Design Realizes Long-Time Zero Liquid Penetration

Integrated Thickened Sealing Edge Mold Design Realizes Long-Time Zero Liquid Penetration

Our Leakproof Bagasse Containers adopt self-developed integrated thickened sealing edge one-piece molding technology, which forms a tight fit between the container body and matching lid to block lateral soup and grease overflow. Combined with thickened dense fully biodegradable PLA anti-leak coating on the inner wall, it fundamentally solves the core industry pain point of ordinary thin pulp containers seeping soup and sauce from gaps during transportation. The coating and base material are both fully compostable without microplastic residue, balancing outstanding liquid isolation performance and complete environmental friendliness to meet strict global import compliance standards.
Balanced Heat, Oil & Liquid Resistance Adapts to Multi-Scenario Soup & Oily Food Packaging Demands

Balanced Heat, Oil & Liquid Resistance Adapts to Multi-Scenario Soup & Oily Food Packaging Demands

Every leakproof bagasse container carries out targeted thickened box wall and sealing edge reinforcement design, integrating three core superior performances: stable 104°C high temperature microwave resistance, outstanding heavy oil & soup isolation barrier and solid compressive stack toughness. No liquid overflow, grease penetration or structural collapse accidents occur during multi-layer stacking long-distance takeout transportation of boiling hot soup, hot pot broth and creamy stir-fry, eliminating after-sale complaint losses brought by leakage defective packaging for wholesale merchants. Strict batch-by-batch hot soup long-time immersion aging testing guarantees uniform stable leakproof usability under various high-liquid catering service environments.
