A kind of carton and its production process

Abstract

The invention relates to a production process of a carton, which includes a film covering process, and the film covering process includes the following steps: A1. Prepare materials, prepare corrugated cardboard, thermal insulation film and isolation film; A2. Cover film, cover the surface of the corrugated cardboard with the thermal insulation film ; A3. Punching holes, evenly opening out glue grooves and glue injection holes on the composite corrugated cardboard and insulation film; A4. and overflow into the glue tank; A5. Secondary lamination, paste and fix the surface of the isolation film and the insulation film away from the second cardboard, and the surface of the isolation film attached to the insulation film is bonded with the fixed glue in the glue tank fixed. In step A5 of this process, the isolation film and the heat preservation film are bonded and fixed by the fixed glue in the glue tank, thereby avoiding the recoating of glue on the surface of the isolation film close to the heat preservation film. The steps of the film coating process are simple and the cycle is short.

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
