A kind of carton and its production line

Abstract

The invention relates to a carton, comprising a corrugated box body, the corrugated box body includes a cardboard, and the cardboard is sequentially provided with a corrugated cardboard, a waterproof layer and a protective layer from the outside to the inside of the corrugated box, and the corrugated cardboard is made of corrugated paper The first cardboard, the corrugated layer and the second cardboard are arranged in sequence from the outside to the inside of the box; the waterproof layer and the protective layer are both made of pvc plastic, and the thickness of the protective layer is only One-third of the above waterproof layer. The carton of the present invention has the effect of waterproofing the inside, prevents the frozen items from wetting the box body and reduces the structural strength of the box body, and is suitable for the transportation of frozen items.

Description

technical field [0001] The invention relates to the technical field of carton production, in particular to a carton and a production line 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. As an indispensable part of modern logistics, packaging cartons bear important responsibilities for packaging, product protection, and aesthetics. The physical performance indicators of packaging cartons become the basis for their quality evaluation. In transportation items, such as frozen food, if the transportation time is too long, the frozen food and other items may melt and generate moisture, which will cause the inner wall of the box used to store such items to become wet. Generally speaking, plastic boxes are used to store frozen food, but compared with cartons, plastic boxes are heavier and inconvenient t...

AI Technical Summary

Problems solved by technology

Generally speaking, plastic boxes are used to store frozen food, but compared with cartons, plastic boxes are heavier and inconvenient to carry, and the noise emitted by plastic boxes during transportation is also greater than that of cartons.

However, most of the existing cartons lack waterproof function, and the structural strength of the carton body will be reduced after the items are wetted, resulting in damage to the carton body.
