The packing box (such as a carton) is usually used as a wrapper of goods or an outer layer object for protecting goods, the volume of the packing box is changed due to the size of the goods, and the packing box is an indispensable part of modern logistics and bears important responsibility for containing and protecting products.
The main heat-preservation packing boxes in the cold chain market at present are made of petroleum or plastic, are difficult to biodegrade and are not environment-friendly, and particularly comprise the following main materials:
first, the foam box, its main material uses EPS (polystyrene foam), and the foam box is damaged easily in the use, and the box thickness of foam box is big, and is bulky, and is not nimble enough, and the cost of transportation is also high, and simultaneously, the recovery cost of foam box is high, and easily produces a large amount of wastes, pollutes the ecological environment.
As patent application CN201911331130.2 discloses a foam tank of easy change, including foam tank and foam tank lid, the foam tank comprises foam tank body and foam tank curb plate, foam tank body and foam tank curb plate sliding connection, the foam tank body comprises four foam pillars and foam tank bottom plate integrated into one piece, four the foam pillars by the foam tank bottom plate is separated for spout pillar and sill pillar, foam tank body top is equipped with the foam tank lid. The invention can partially replace the foam box when the foam box is damaged, and the replacement process is simple and convenient, but the problems that the adopted materials are difficult to biodegrade and are not environment-friendly still exist.
Secondly, the main material of the cotton clamping box is EPE (high pressure polyethylene, also called pearl wool), the heat preservation effect is not as good as that of the foam box, and meanwhile, the used material is difficult to biodegrade.
As patent application CN201921567929.7 discloses a dampproofing and waterproofing's corrugated box, including box and case lid, the box includes first corrugated sheet, the inboard of first corrugated sheet has the cotton layer of pearl through the sticky gluing of dry-type waterborne compound film, the cotton layer of pearl is kept away from one side of first corrugated sheet and is had the second corrugated sheet through the sticky gluing of dry-type waterborne compound film, the one side that the cotton layer of pearl was kept away from to the second corrugated sheet is pasted and is had EPTFE water proof membrane, one side that the cotton layer of pearl was kept away from to first corrugated sheet is scribbled and is equipped with hydrophobic coating. The utility model discloses a cooperation through hydrophobic coating, wear-resistant coating, the cotton layer of pearl and EPTFE water proof membrane is used, has reached dampproofing and waterproofing's purpose, has solved current corrugated box when using, does not possess dampproofing and waterproofing's function, is drenched easily by the rain or is placed and intake when the moist place of environment to lead to the corrugated paper to be changed the softness by water erosion back deformation, lose the problem of storing function. However, the corrugated case is made of pearl wool, so that the corrugated case still has difficulty in degrading and is not beneficial to environmental protection.
In summary, the problems of the prior art are as follows: the materials adopted by the existing heat-insulating packaging box are not easy to degrade, are not beneficial to recycling and are not beneficial to environmental protection.
