Choice of water-based adhesive

Application index

Some packaging and printing enterprises reflect that some water-based adhesives will degummy soon after gluing; Viscosity is not stable, sometimes bond firmly, but sometimes not bond; It works well in hot weather, but it doesn't work in cold weather.In fact, this is due to the lack of understanding of water-based adhesive application indicators.

The preparation method and production process of different types of water-based adhesives are different, so their chemical and physical properties are also different, that is, the application index is different.The most important application indexes of water-based adhesives in packaging and printing industry mainly include bond strength, high and low temperature resistance, moisture resistance and stickiness. The defects such as weak bond, degumming and brittle film often occur in practical application are basically caused by the above four application indicators.

High cost performance

Choose water-based adhesive, should be "quality first, price second" as the principle. However, some packaging and printing enterprises view is very one-sided, mistakenly think that the higher the price of water-based adhesive, the better the quality; Otherwise, the quality is worse.

In fact, this is not absolute. When choosing water-based adhesives, we should first understand the characteristics of the processed products and choose the adhesives with higher cost performance, which is a reasonable way to choose and buy.

Different products in different fields of application indicators are different processes, here is only a brief introduction, if you need to know more products in detail, you can contact our technical staff for consultation.
