Packaging Adhesive

Packaging adhesive is an adhesive material specially used in packaging manufacturing processes. It is primarily employed for strong, durable bonds between various packaging substrates such as paper and cardboard, coated materials, films and other packaging parts.

Modern Packaging adhesive must have much higher bonding force than traditional bonding materials, and it should have a quick setting time and compatibility with automated production equipment. To satisfy these industrial needs, Adhesive (Shanghai) Co., Ltd. develop the adhesive products with optimized molecular structures.

Our adhesive has excellent initial adhesion and long-term bonding reliability, suitable for manufacturers who need to have stable production and efficient manufacturing.

The product can be customized according to different production environments, such as bonding materials, machine conditions, application temperature and required bonding performance.

Product Performance

Various Packaging

The primary requirement of packaging adhesive is reliable adhesion under different production and transportation conditions. Adhesive (Shanghai) Co. Ltd independently develops high-viscosity hot melt adhesive formulas that provide excellent initial tack and long-lasting bonding strength.

Depending on different packaging materials and application requirements, the bonding strength of our Packaging Adhesive can reach:

• Peel strength: ≥3.5 MPa
• Tensile bonding strength: ≥4.0 MPa
• Adhesion retention rate: ≥99%

This is very good bonding performance which can prevent packaging failure due to vibration, temperature change and long distance transportation.

Fast Setting and High Production Efficiency

Adhesives need to be able to withstand high-speed production lines in modern packaging factories. The typical water-based glues can take longer to dry, impacting production efficiency.
