Carton and production process thereof

Abstract

The invention relates to a carton production process, which comprises a film coating process, and the film coating process comprises the following steps: a1, preparing materials, namely preparing a corrugated board, a heat preservation film and an isolation film; a2, conducting film coating, specifically, the surface of the corrugated board is covered with the heat preservation film; a3, punching,specifically, glue containing grooves and glue injection holes are evenly formed in the composite corrugated board and the heat preservation film; a4, conducting glue injection, specifically, fixingglue is injected into the glue injection holes, so that the fixing glue is fixedly poured into the space between a second paperboard and the corrugated paperboard and overflows into the glue containing grooves; and a5, conducting secondary film coating, specifically, the isolation film and the surface, away from the second paperboard, of the heat preservation film are bonded and fixed, and the surface, attached to the heat preservation film, of the isolation film is bonded and fixed to the fixing glue in the glue containing grooves. According to the technology, in the step a5, the isolation film and the heat preservation film are bonded and fixed through the fixing glue in the glue containing grooves, so that the situation that the surface, close to the heat preservation film, of the isolation film is coated with the glue again is avoided, and the film coating process is simple in step and short in period.

Description

technical field [0001] The invention relates to the technical field of carton production, in particular to a carton and its production process. 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. Cartons are commonly used with three layers and five layers, and seven layers are rarely used. Each layer is divided into lining paper, corrugated paper, core paper, and face paper. The color and feel are different, and the paper (color, feel) produced by different manufacturers is also different. With the improvement of people's living standards, people's demand for fresh fruits, flowers and other items is also increasing. However, the preservation and transportation of such items often require a certain heat preservation function. The existing means of transportation for storing such items mainly It is a foam ins...

Problems solved by technology

With the improvement of people's living standards, people's demand for fresh fruits, flowers and other items is also increasing. However, the preservation and transportation of such items often require a certain heat preservation function. The existing means of transportation for storing such items mainly It is a foam insulation box. The foam insulation box is made of integrally formed foam material, which has the effect of heat preservation. However, the foam material outside the foam insulation box is exposed, which is prone to scratches during transportation, causing the foam material to be damaged and dropped, polluting the environment. Moreover, the wall thickness of this type of foam insulation box is very large, and a large amount of foam material is used, and the foam material is difficult to degrade in a natural state, so this type of foam insulation box is not environmentally friendly.

However, most of the existing cartons only stay at the stage of paper boxes with relatively simple structure. Paper materials are easy to degrade and are more environmentally friendly than foam materials. However, cartons do not have the function of heat preservation and are not suitable for storage and storage of fresh fruits and flowers Therefore, there is an urgent need for an environmentally friendly carton with thermal insulation effect to meet the storage and transportation of fresh fruit items.

In addition, the existing carton technology is difficult to meet the manufacture of the carton, it is urgent to improve the existing carton technology
