Environment-friendly high-strength composite paperboard tray

Abstract

The invention discloses an environment-friendly high-strength composite paperboard tray, composed of layers of materials, sequentially including a wood-plastic board layer, a honeycomb paperboard layer, a wood-plastic frame layer, a honeycomb-shaped polylactic acid elastic pressboard and an elastic bottom spacer from the top down, wherein the honeycomb-shaped polylactic acid elastic pressboard is formed by mold pressing toughened polylactic acid materials, and has good cushioning and toughness; the elastic bottom spacer and the wood-plastic board layer are good in intensity and elasticity, thus being capable of increasing the intensity of the tray and providing good rebound resilience; the honeycomb paperboard layer can provide good impact resistance; the wood-plastic frame layer includes a square hollow body composed of an upper panel, a lower panel and side boards and a plurality of reinforcing columns arranged between the upper and lower panels, the side boards are provided with fork holes, and the positions of the fork holes and the reinforcing columns are staggered. The wood-plastic frame layer can increase the intensity and impact resistance of the tray. The environment-friendly high-strength composite paperboard tray has excellent intensity, is environment-friendly in material, capable of being used repeatedly, greatly reduced in industrial use cost.

Description

technical field [0001] The invention relates to the field of loading trays, in particular to an environmentally friendly high-strength composite cardboard tray for industrial use that can be fully degraded and has high strength. Background technique [0002] In industry, the amount of loading pallets is huge, and most of the pallets are still made of pure wood. On the one hand, although wood boards are environmentally friendly materials, the use of a large amount of wood and the resulting felling of wood will cause huge environmental hazards. At the same time, wood boards have poor cushioning performance, are easily damaged and cannot be reused. Moreover, the price of planks is more expensive, which also puts pressure on the cost of users. And because wooden pallets are easily damaged, the replacement cost is also very high. Therefore, if a pallet substitute wood with a lower cost can be provided while ensuring its strength and compression resistance, it will undoubtedly h...

Problems solved by technology

In the field of pallet development, most of the pallet development is still focused on the structural design of the pallet, such as a degradable environmental protection flat pallet disclosed by CN104085590A, and a detachable pallet for transportation and storage disclosed by CN104071424A, all adopt special structures The design has reached a higher strength, but the structural design still cannot break through a limit, and this type of tray is still relatively easy to damage

And only from the structural point of view, it is impossible to achieve a greater breakthrough in strength.
