Aluminum Coated Flexible Package Adhesive JL1172/GL1172

The adhesives offers superior chemical resistance compared to their one-component polyurethane adhesive, making them ideal for applications where exposure to various chemicals is a concern.
They typically provide higher bond strength and better durability, ensuring reliable performance in demanding environments. These pu glue adhesives are versatile enough to be used in plastic-plastic and plastic-aluminum package structures, accommodating a wide range of packaging needs.
Particularly noteworthy is their excellent ability to create strong composite bonds with aluminized products, enhancing the barrier properties and overall integrity of flexible packaging solutions.

2.Applicable model:

Has an excellent composite effect on aluminum coated products.

Suitable for various speeds of dry laminating machines 

3.Recommended ratio:

20:20. 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℃.
