Adopting the blending process of corn starch and food grade PP modification, retaining the environmentally friendly characteristics of bio based low-carbon and biodegradable materials, reducing the proportion of plastic use, and complying with global carbon neutrality and plastic ban policies; At the same time, relying on the support of PP material, the toughness and structural strength of the product are greatly improved, completely solving the problems of low temperature brittleness, compression fracture, and bottom collapse of pure starch dumpling boxes. It balances environmental protection and practical performance, and the comprehensive quality far exceeds ordinary single material packaging. The size of the single cell is suitable for the specifications of conventional dumplings, Wonton, and quick-frozen pasta. It is stored in an independent slot. The food materials are not in contact with each other. The modified composite materials are suitable for ultra-low temperature environment. The temperature resistance range is -40 ℃~120 ℃, and can be used for long-term refrigerator freezing

Paired with a high fit sealed buckle cover, it fits tightly, effectively preventing dust, moisture, and odor, isolating cold chain moisture and bacteria, and ensuring fresh and hygienic ingredients. The box body is equipped with precise stacking card slots, which can be neatly stacked in multiple layers for storage.

Support full dimensional customization: adjustable single grid depth, overall size, box thickness, matte/glossy texture, can print brand logos, product parameters, environmental labels, and support private mold exclusive development. The factory is equipped with a fully automatic vacuum forming production line, with mature mass production, stable quality control, and high shipping efficiency.
