PP four-layer square lunch box

This PP four-layer square lunch box is a standardized compartmentalized packaging set specially designed by Jiekang Xuepai Plastic Industry for frequent commercial use scenarios such as Chinese fast food, business group meals, chain takeout services, and government and enterprise canteens. It is produced in an ultra-clean 100,000-level standard workshop and equipped with a fully automatic injection molding line. The entire production process strictly follows food contact safety standards, without any odor, impurities, or the addition of recycled waste materials. The material is pure and safe, suitable for long-term use with both hot and cold dishes, oily braised foods, and soup-based foods.

Details

The overall design adopts a thickened base and an integrated molding process, which makes the structure more resilient and resistant to compression, dropping, and deformation. It is suitable for multi-layer stacking storage, long-distance logistics distribution, and batch catering transportation in demanding commercial scenarios, significantly reducing the damage, leakage of soup, and loss of food. The raised sealing cover has a tight fit, with uniform edge sealing, and can still prevent leakage and preserve freshness even during jolting and tilting transportation.

The material supports refrigeration preservation and short-term microwave heating, catering to various usage scenarios such as pre-preparation of meals before meals, storage of leftover meals after meals, and customer re-heating for meals. The complete set of food contact qualifications is complete, and it has passed authoritative third-party testing, compliantly entering various food delivery platforms, supermarkets, and government and enterprise canteen projects. It is a high-performance, stable, and long-term commercial batch purchase preferred choice.

Brand Philosophy: Craft every lunch box with solid workmanship, solving all pain points of takeaway packaging – leakage, deformation, lack of environmental friendliness, and insufficient heat resistance. Factory-direct production eliminates middleman markups, maximizing cost advantages for bulk orders. We hold comprehensive food-contact qualification certificates and have passed national food packaging safety testing.
