Color printing packaging is light in weight, easy to carry, and the source of raw materials is wide, and it is widely used in food, traditional Chinese medicine, daily necessities and other industries. Do you know what are the common production processes of packaging? First, the film Laminating process is a kind of surface processing process, after printing is completed, this process is also calle...
Water-based adhesives for printing are very common, which mainly include water-based pasting adhesive, laminating adhesive, water-based sealing adhesive and so on. Water-based laminating adhesive Water-based film adhesive has been widely used in recent years for its high brightness, low cost, easy operation and water-based environmental protection. Water-based film adhesive is mainly divided into ...
Coated adhesive is generally used in the field of printing, processing the surface of the printed matter, so as to improve the gloss of the printed matter, and play a certain protective effect on the printed matter, coated adhesive refers to the BOPP film on the paper of a kind of glue. Divided into oil-based laminating glue and water-based laminating glue, water-based laminating glue is widely us...
There are many factors affecting the quality of the film, in addition to paper, ink layer, film, adhesive and so on In addition to the objective factors, it is also affected by subjective factors such as temperature, pressure, speed, and glue amount. If these factors are not handled well, various laminating quality problems will occur. There are snowflakes on the product 1.The amount of glue is to...

1. The effect of membrane material There are dust adsorption, particle impurities, poor plasticization and other crystal points in the film. The moisture absorption on the film surface of the material and the precipitation of additives in the material will cause composite bubbles. The thickness of the film should be as uniform as possible, if the distribution is uneven, it is easy to cause the imb...
As a kind of widely used adhesive, coated adhesive has a variety of processes. Here are some of the common processes used: 1. Hot melt coating: hot melt coating is to place a layer of film on the surface of the print, and then through hot pressing the film and the print together.In this process, the laminating glue is heated to turn it into a liquid, which then forms a uniform coating between the ...
Aluminized film glue is a composite material that binds aluminum film and other materials together by glue. It is usually used in paper packaging to prevent moisture, oxidation, heat insulation and pollution. First of all, the aluminized film glue can effectively prevent the paper from absorbing moisture and oxygen in the air, thereby maintaining the dryness and freshness of the product and extend...
According to the different raw materials and equipment, the coating process can be divided into two kinds of coating process and pre-coating process. That is to say, the film used in the coating process is now coated, and the adhesive used is generally solvent-based and emulsion type, prepared according to need. However, the film used in the pre-coating process is pre-coated, and the adhesive used...
