Color printing packaging is mainly used as packaging products, and its appearance requirements are relatively high. When using, there will be some influencing factors that lead to the collapse of the packaging. Once the collapse will affect the overall use effect, and the collapse is often related to many factors, the following will teach you how to prevent this phenomenon.

1. When producing color printing packaging, it is necessary to control the moisture content inside the packaging box

The moisture content of paper should not be too high. Everyone knows that too high moisture content will affect the hardness of the product, and then affect the corners of the packaging box after molding.

2. The paper used in the packaging box should be highly adhesive

The adhesive strength is the adhesive force between the corrugated paper and the face paper. If the quality is not enough, after applying the adhesive, it will be found that the opening of the packaging box will cause the reduction of the compression resistance of the packaging box, which will cause the collapse of the packaging box.

3. In color printing packaging production, waterproof varnish and water splashing agent should be properly used, which will solve the problem of waterproof and moisture-proof on the surface of the packaging box.

4. Control the use of base paper

Check the sizing of packaging paper and the water absorption index of base paper surface. If the surface sizing of the base paper is poor, the water absorption will be high, and it is easy to be affected by the cold and humid environment of the hand cold storage, which will lead to moisture regain and softening of the packaging box, and reduce the compressive strength of the finishing.

5. The gap pressure control in the production process should be moderate

In particular, it should be noted that the gap pressure of the paste on the box pasting machine should not be too small, and the gap pressure of the sun wheel on the double-sided machine and die-cutting machine should be controlled within a reasonable range to avoid crushing and affecting the compressive strength of the cardboard packaging box.

The above is the introduction of prevention methods for collapse of color printing packaging. In addition to the control of raw materials during the production of packaging, attention should also be paid to the correct control of methods during the production and processing. Only the correct production and processing can prevent collapse.
