What are the types of adhesive layers for A4 stickers (such as water-based adhesive, oil-based adhesive, hot melt adhesive, etc.)?

There are various types of adhesive layers for A4 stickers, mainly including the following:

1.Water glue: Water glue is a common type of self-adhesive adhesive layer, which usually has good adhesion and environmental friendliness. Water glue adhesive materials are suitable for various printing and printing methods, such as laser printing, inkjet printing, etc., and are widely used in fields such as product labels and barcode labels.

2.Oil glue: The adhesive layer of oil glue stickers is mainly composed of oily substances, which usually have strong adhesion. Oil glue adhesive material is suitable for occasions that require high viscosity, such as outdoor advertising, car labels, etc. However, it should be noted that oil-based adhesives may not be as environmentally friendly as water-based adhesives.

3.Hot melt adhesive: Hot melt adhesive is a type of adhesive layer that is melted by heating and applied to the back of adhesive materials. It has the characteristics of fast curing and strong adhesion, and is suitable for high-speed labeling on automated production lines. In addition, hot melt adhesive stickers have good water and oil resistance, making them suitable for label applications in some special environments. For example, A4 paper packaging special hot melt adhesive (such as HJ526E) has the characteristics of good adhesion, light odor, and no wire drawing, which is suitable for the bonding needs of A4 paper packaging.

In addition to the three common types of adhesive layers mentioned above, adhesive materials may also use other types of adhesive layers, such as pressure-sensitive adhesives, solvent based adhesives, etc. These adhesive layer types have their own characteristics and are suitable for different application scenarios and needs.

When choosing A4 adhesive, it is necessary to comprehensively consider factors such as specific application scenarios, types of label materials, and printing and printing methods to select the most suitable adhesive layer type. At the same time, attention should also be paid to the environmental friendliness, weather resistance, water resistance and other performance indicators of adhesive materials to ensure the quality and stability of the labels.
