Lining improved type environment-friendly logistics packaging box and manufacturing method and unfolding structure thereof

Abstract

The invention relates to the field of logistics packaging boxes, and specifically relates to a lining improved type environment-friendly logistics packaging box comprising a box body. A lining bag is arranged in the box body in an attached mode, openings are correspondingly formed in the lining bag and the box body, and the four corners of the lining bag are connected with the four corners in the box body in a sealed mode to form four sealing parts. An unfolding structure of the environment-friendly logistics packaging box comprises a box face, a first top cover and a first connecting cover are arranged at the bottom of the box face, a second top cover, a third top cover and a second connecting cover are arranged at the top of the box face, and auxiliary pasting faces are arranged on the first connecting cover and the second connecting cover correspondingly. According to the lining improved type environment-friendly logistics packaging box, a manufacturing method of the lining improved type environment-friendly logistics packaging box and the unfolding structure of the lining improved type environment-friendly logistics packaging box, the leakage rate is decreased through the design of the lining bag, the sealing performance is guaranteed, residues are reduced, the stability during transportation is high, and the box body has the high load bearing capacity, the high anti-falling capacity, the high water resistance, the high moisture resistance, the high oil stain resistance and the like.

Description

technical field [0001] The invention relates to the field of logistics packaging boxes, in particular to an improved inner-lined environmentally friendly logistics packaging box, a manufacturing method and an unfolding structure thereof. Background technique [0002] Cartons are the most widely used packaging products. According to different materials, there are corrugated boxes, single-layer cardboard boxes, etc., with various specifications and models. In modern logistics, cartons have become an indispensable part, bearing important responsibilities for packaging, product protection, and aesthetics. [0003] But at present, in the field of logistics packaging, there are many problems that affect economic benefits. For example, when the volume of the transportation package is too large, the transportation work will become relatively difficult. In particular, when the traditional packaging and transportation industry transports items such as the chemical dangerous goods ind...

AI Technical Summary

Problems solved by technology

[0003] However, in the field of logistics packaging, there are many problems affecting economic benefits.

For example, when the volume of the transportation package is too large, the transportation work will become relatively difficult. In particular, when the traditional packaging and transportation industry transports items such as the chemical dangerous goods industry, there are problems such as packaging difficulties, recycling difficulties, and processing difficulties. , There are also certain limitations in the types of raw materials and cost ranges, and these problems affect the steady development of social productivity

[0004] Some existing solutions are to use plastic barrels, metal barrels or wooden barrels to package and transport different items, but the problems brought about by this are high cost and greatly increased work complexity. Lining is used to package and transport food, dangerous goods and other items, but the problems brought about by this are low strength, poor waterproof and moisture-proof performance
