TPU(Thermoplastic polyurethanes) is a thermoplastic polyurethane elastomer rubber. Mainly divided into polyester type and polyether type, it has a wide hardness range (60HA-85HD), wear resistance, oil resistance, transparency, good elasticity, in daily necessities, sporting goods, toys, decorative materials and other fields are widely used, halogen-free flame retardant TPU can also replace soft PVC to meet more and more areas of environmental protection requirements.
The so-called elastomer refers to the glass transition temperature is lower than the room temperature, the elongation at break is >50%, and the resilience is relatively good after the external force is removed.
Polyurethane elastomer is a special category of elastomers, polyurethane elastomer hardness range is very wide, performance range is very wide, so polyurethane elastomer is a class of polymer materials between rubber and plastic. It can be heated plasticized, has no or little cross-linking in chemical structure, and its molecules are basically linear, but there is some physical cross-linking. This type of polyurethane is called TPU.

We will choose packing materials such as wooden boxes, pallets, wooden frames, aviation cases, etc. At the same time, foam bubble film stretching film is used to fill or protect the inside and outside of the goods to prevent unnecessary losses caused by movement of the goods or collision with each other.
At the same time, it is necessary to ensure the waterproof and moisture-proof ability of the packaging, and consider the multi-directional customers to let customers buy peace of mind.
Sea, land and air transport modes to meet the ultimate needs of customers, is bound to bring superior purchasing experience for customers.
At the same time we constantly improve the quality of packaging, improve packaging methods, reasonable choice of means of transport and transport routes, the development of social transport system.
