What are the types of adhesives used for circular colored copperplate label paper?

The types of adhesives used for circular colored copperplate label paper mainly include the following:

1、 Water-based adhesive

Water based adhesive is an environmentally friendly adhesive that does not contain organic solvents and does not pose a threat to the environment or user health. It is suitable for pasting various materials, including copperplate paper labels. However, the bonding strength of water-based adhesives is relatively low and may not be suitable for situations that require long-term adhesion or high stress. In addition, water-based adhesives are prone to moisture, which may affect their bonding effectiveness and durability.

2、 Acrylic adhesive (pressure-sensitive adhesive)

Acrylic adhesive, also known as pressure-sensitive adhesive, has the advantages of strong adhesion, water resistance, heat resistance, corrosion resistance, oil resistance, etc. It is suitable for attaching complex materials, including copperplate paper labels. Acrylic adhesive can provide stable bonding effect and resist moisture and oil erosion to a certain extent. However, its cost is relatively high and may not be suitable for all occasions.

3、 Hot melt adhesive

Hot melt adhesive is a type of adhesive that is melted by heating before use. It is suitable for fast pasting and automated production processes. Hot melt adhesive has a low melting point and heats up quickly, making it possible to quickly attach copperplate paper labels. However, the liquid of hot melt adhesive is relatively viscous, and caution should be taken when using it to avoid spilling. In addition, if it needs to be removed or removed after pasting, it may damage the texture of the cardboard box.

4、 Adhesive glue

Adhesive glue is a specialized adhesive used for making adhesive labels. It usually has good adhesion and can firmly stick copperplate paper labels on various surfaces. There are various types of self-adhesive adhesives, such as water-based adhesive, hot glue, black glue, removable adhesive, oil glue, etc. These adhesive coatings have good adhesion and do not overflow or peel off. They can be stored for a long time and used for a longer period of time. The waterproof performance of adhesive labels is also good, which can resist the erosion of moisture to a certain extent.

In summary, the adhesive types used for circular colored copperplate label paper mainly include water-based adhesive, acrylic adhesive (pressure-sensitive adhesive), hot melt adhesive, and self-adhesive adhesive. When selecting adhesive, it is necessary to choose according to specific usage requirements and environmental conditions to ensure the adhesive effect and durability of the label.
