Factors affecting the production of paper boxes

To a large extent, paper boxes promote and beautify commodities with their beautiful shapes and decorations, improving their competitiveness. As the shape and structure design of paper boxes are often determined by the shape of the packaged goods, there are many styles and types, including rectangular, square, polygonal, shaped cartons, cylindrical, and so on. However, the manufacturing process is the same. The raw materials of cartons are generally pulp and corrugated paper, which are mostly used for holding goods and can be recycled.

The following is a list of contents.

Material factors

1, Paper deformation on paper boxes forming the impact of

The paper itself is uneven and curly, after printing, die-cutting, and gluing, it will affect the beauty of the box shape.

2、The impact of paper type on the fastness of the glue box

Different kinds of paper have different effects on the fastness of paper boxes. The printing of wine boxes and medicine boxes mainly uses white cardboard, gray background white cardboard, gold and silver cardboard, and some other special papers. White cardboard has high quantitative grammage, good surface flatness, high flatness, and high tightness. Gray-backed white cardboard has a rougher bottom surface, strong water absorption, and better permeability to adhesives. And gold and silver cardboard surface smoothness, and flatness are higher, but generally have to go through the lamination process.

3、The influence of adhesive on the fastness of the adhesive box

Adhesiveness is one of the important factors affecting the fastness of paper boxes. The adhesive solid content is high, fast drying speed, good bonding performance, high and low temperature, moderate hardness, cold and heat resistance, fast initial adhesion speed, and high-speed bonding can be achieved.

Process factors

1, The impact of surface treatment on the quality of adhesive boxes

The impact of surface treatment is mainly reflected in the printing on the paper boxes and then completely varnished and laminated products. The surface finish of the gluing machine is polished by installing an edge grinding device on the gluing machine, but this is a difficult process.

2、The influence of the die-cutting process on the box shape

The production process of the die-cutting version also has a great influence on the box shape. The manual die-cutting version is crude, with poor specifications, multi-point cutting, and bending. Due to the elasticity of the paper itself, when the two sides of paper boxes are shaped and folded back, the cut of the opening side will expand outward, forming the phenomenon of the opening being opened.

The influence of process parameters on the quality of plastic boxes

The process parameters should be set reasonably to avoid inaccurate lamination, poor lamination, glue release, glue overflow, sticky flowers, and other failures. The general factors to be considered are the characteristics of the paper material, the size of the number of openings, surface treatment, etc. The pressure after gluing is based on the paper boxes sticking firmly and without indentation.
