Pet/PE Daily Chemical Products Packaging Polyurethane Laminating Adhesive

Product Description

 

Product Description

This adhesive is a high-performance product designed for multi-layer structures such as nylon/AL, PET/AL, and CPP/AL, which can withstand high temperature steaming and boiling at 135ºC for 40 minutes. It has good compound strength especially for thick base ink. It has the characteristics of short curing time, relatively soft film, no peculiar smell, relatively flat and no decrease in strength after steaming and boiling.

Installation Instructions

1. When preparing the adhesive, it is best not to stir with a wooden stick. First use an electronic scale to accurately weigh the adhesive, hardener and ethyl ester; then add the adhesive to an appropriate amount of ethyl ester and stir into a vortex; then add the hardener and stir, and finally pour in the remaining ethyl ester and stir well. After fully stirring, it can be used after filtering through a 300-mesh filter. The filtered adhesive should be sealed with a lid to avoid moisture contamination.
2. The amount of adhesive applied: the amount of adhesive applied (calculated by the amount of dry adhesive g/m²) is one of the main factors affecting the strength of the composite film. The amount of adhesive should be determined according to different materials, printing conditions and purpose of usage.

3.In general, the larger the amount of adhesive applied, the higher the strength of the composite film. If you want higher strength, try to increase the amount of adhesive applied as much as possible.
 

Our Advantages

Wide Bonding Range: Excellent bonding strength to a variety of substrates (especially BOPP, PET, nylon, aluminum foil, galvanized film, etc.).
Tunable Performance: By adjusting the chemical formula, adhesives with different initial tack, final strength, heat resistance, and chemical resistance (acid resistance, oil resistance, and resistance to contents) can be designed.
High Flexibility: The cured adhesive film is soft and matches the elongation of the plastic film, preventing brittleness due to folding or compression, ensuring the durability of the packaging bag.
Excellent Weather Resistance: High-quality polyurethane adhesives provide good resistance to high and low temperatures (e.g., freezing and retorting conditions).
High Transparency: The cured adhesive layer is clear and transparent, not affecting the appearance of the packaging or printing effects.

Packaging & Shipping
