Description

High strength quadrature corrugated paper tray

Technical Field

The utility model relates to a tray, concretely relates to corrugated paper tray.

Background

According to the material classification of tray, the tray can divide into: the wooden pallet in China accounts for about 90 percent of the total quantity of the pallet. Wooden tray wastes valuable resources, does not accord with the environmental protection requirement, and the plastics substitute also has the problem of polluting the environment, and its manufacturing cost is all higher in addition. Non-wood pallets are mainly used for wood-substitute packaging in developed countries. The development of high-strength corrugated trays will rapidly add to more industries in the future.
