How to Strengthen the Control of Source Quality of Corrugated Box Products

[China Packaging Network News] strict control of raw materials in order to ensure the quality of carton production. We know that the quality of raw materials directly affects the quality of the carton products. It can be said that raw materials are the source of quality control for carton products and are very important.

Among them, the quality of the binder and the base paper has a great influence on the quality of the cartons.

Adhesive (commonly known as glue) is an important raw material for corrugated cardboard, and its quality is an important part of determining the quality of cardboard products. The main material of the adhesive is starch. The degree of fineness, protein and fat content of the starch will affect the performance of the adhesive. If the use of poor quality starch, for example, when the protein and fat content of starch is too high, and the fineness of the starch is less than 98 mesh, despite the high degree of oxidation during production, but the viscosity of the material is generally only 20 seconds After a few days storage, the glue will become thicker, it will lose its proper fluidity, and the foam will be large when used, which will affect the uniformity and viscosity of glue coating. If such a sticker is used to apply a sticker board, it is likely to cause quality problems such as blistering, degumming, and poor adhesion.

In addition, the technical specifications of the base paper also affect the quality of corrugated board processing. Among them, the corrugated paper, boxboard's ring pressure strength, basis weight, moisture, burst resistance index, folding resistance, and water absorbency directly affect the corrugated box forming process. The intensity of quality.

Therefore, according to the actual situation of the company, it is necessary to purchase some necessary testing equipment and carry out inspection and acceptance according to the quality standards of raw materials. It is worthwhile to carry out effective inspection and control of the incoming raw materials. Through the implementation of inspection and control measures, enterprises can make scientific and accurate testing of the quality of raw materials, fundamentally eliminate unqualified raw materials, ensure the quality of the processing of cartons, and effectively control the source quality of production.
