In the post-press process of the printing and packaging industry, the film improves the brightness of the printed matter and enhances the water resistance. It provides a beautiful visual effect for people's life. With the continuous emergence of various processes, equipment and glues, there have been some new trends in post-press coating. First, the proportion of water-based coating is increasing, and the oily coating adhesive is close to fading out of the market.

First, the proportion of water-based coating is increasing, and the oily coating adhesive is close to fading out of the market.

When the coating process is initially developed, all solvent-based adhesives are used. Generally, it is a one-component SIS oily adhesive and a two-component polyurethane oily adhesive. With the development of science and technology, water-based laminating adhesives have gradually improved and formed, and people have become more aware of the harm caused by solvent-based laminating adhesives:

A.It is harmful to the operator, because the benzene and ester in the solvent will enter the human body fluid from the human surface, and then enter the human blood, and the long-term large dose of contact causes too much accumulation in the body, resulting in various diseases.

B.Flammable and explosive, high hazard level, domestic and caused heavy losses repeatedly reported.

C.high cost.

D.Increase VOC emissions and pollute the environment.

E.the solvent in the product remains for a long time, endangering later users. The water-based adhesive successfully overcomes the above shortcomings.

Second, with the gradual improvement of the production process of water-based laminated adhesive, the cost performance and special performance are becoming more prominent.

1.The earliest application and popularity of water-based laminating adhesives are VAE laminating adhesives. The adhesive has high brightness, strong capping ability and excellent operating performance. However, it has high cost, poor adhesion and poor low temperature resistance.

2.The successful setting and gradual improvement of acrylate polymer emulsion in the film adhesive ushered in the spring for the large-scale promotion of water-based film adhesive.

Acrylic resin coating adhesive has strong adhesion, high cost performance and strong adaptability, and successfully overcomes the shortcomings of VAE water-based coating adhesive.
