Tray features: Environmental protection engineering PE material, strong structure, impact resistance, durable. Professional imported material, firm, durable, corrosion resistance. Can be stacked in multiple layers, easy to transport and reduce storage space. (1) Low cost, the same size of the product, the cost of rotoplastic mold is about 1/3 to 1/4 of the cost of blow molding and injection mold. (2) The product is formed once by rotoplastic process, acid and alkali resistance, corrosion resistance, wear resistance, fall resistance, easy to clean, good sealing, and can protect the product contents from damage. (3) The corners of the products formed by the special process are 15%-20% thicker than the surface, and there is almost no material return in the production process, and the rotomizing process has a high material utilization rate. (4) Good air tightness, high toughness, high resilience, to ensure no deformation. (5) Rotoplastic products can be filled with foam materials to achieve thermal insulation and refrigeration. (6) Simple maintenance, long service life, comprehensive use of cost-effective. (7) Positioning foamed plastic buffer damping system, vibration, vibration conditions to ensure the safety and reliability of the carrier.
