Problems solved by technology

Many express packages are over-packaged, resulting in a large number of waterproof packaging bags, packaging cartons, tapes and internal fillers being discarded as packaging waste, causing great pollution to the environment and a great waste of resources
Some packaging waste takes hundreds of years to degrade in nature, and cannot be effectively recycled. It is mainly disposed of by incineration and landfill, which has a great impact on the environment

Abstract

The invention discloses an integrated packaging case and a manufacturing method thereof, wherein the integrated packaging case comprises an outer shell and an inner shell. The outer shell is providedwith a first outer surface and a first inner surface, the inner shell is provided with a second outer surface, the first inner surface is connected with the second outer surface, the inner shell is used for wrapping goods, the density of the outer shell is larger than the density of the inner shell, and the outer shell and the inner shell are of integrally formed structures. According to the integrated packaging case, through injection molding processing production, the outer shell and the inner shell are integrally connected closely, the integrated packaging case is made of a single materialand convenient to recycle, and secondary processing can be carried out for cycle use. Main compositions of raw materials are starch or plant fibers which can be rapidly degraded under natural conditions, the degradation rate is high, the starch or the plant fibers is environmentally friendly, and no environmental pollution is caused.

Description

technical field [0001] The invention relates to the field of packaging boxes, in particular to an integrated packaging box and a manufacturing method thereof. Background technique [0002] Now online shopping has become the most common consumption behavior, and the express delivery industry is also developing rapidly. At the same time, the use of express packaging has also shown a blowout growth. Many express packages are over-packaged, resulting in a large number of waterproof packaging bags, packaging cartons, tapes and internal fillers being discarded as packaging waste, causing great pollution to the environment and a great waste of resources. Some packaging waste takes hundreds of years to degrade in nature, and cannot be effectively recycled. It is mainly disposed of by incineration and landfill, which has a great impact on the environment. There is an urgent need for a packaging box that can reduce the use of internal fillers, avoid excessive packaging, facilitate r...
