PU Adhesive Lamination for Flexible Package JP2375/GP2375

This solvent-based two-component polyurethane adhesive is designed for laminating a variety of materials including PET, BOPP, CPP, PE, VMCPP, VMPET, and others. It is compatible with dry laminating machines operating at different speeds, offering versatility in production environments. Known for its fast curing speed, it enables efficient processing and quick turnaround times. The adhesive supports a wide coating concentration range of 25% to 45%, optimizing glue usage and reducing costs.

However, it is not recommended for laminating PE films with high additive content due to potential compatibility challenges. This makes it ideal for applications where rapid curing and cost-effective adhesive performance are critical.

1.Physical Datas:

2.Applicable model:

Wide range of coating concentration (25%~45%) and low adhesive

cost.

Not suitable for composite of PE films with high content of additives.

3.Recommended ratio:

20:4. The actual environmental humidity and printing ink have a significant impact on the laminating effect. Customers should adjust the amount of curing agent appropriately according to the actual situation.

4.Operating conditions:

(1) When diluting, add the solvent to the main agent according to the required solid content, stir it thoroughly,

(2)Then add the curing agent, and stir it evenly before use.

(3) The water content of the solvent ethyl acetate shall not exceed 0.03%, and the alcohol content shall not exceed 0.02%

(4) Working concentration 25%~35%

5.Drying:

The drying device should have sufficient air volume, wind speed and temperature. When the drying system is divided into three sections, the temperature from the membrane inlet to the outlet is controlled between 50~60℃, 60~70℃, and 70~80℃.
