Description
1. Shaft-less Unwind & Rewind :
-
Dry Lamination
2. Combination Process :
-
The two substrates, one with dry adhesive and the other with liquid adhesive, are brought together and passed through pressure and heat rollers. This activates the adhesives, causing them to bond with the substrates.
3. Enhanced Bonding Strength :
-
By combining both dry and wet adhesive application methods, dry cum wet lamination ensures superior bonding strength between the substrates, even for challenging materials.
4. Customisation Options :
-
Dry cum wet lamination can be tailored to meet specific application requirements, including adhesive type, thickness, and lamination speed.
5. Wet Lamination :
-
Involves applying a liquid adhesive onto the other substrate surface using methods such as rollers or sprayers. The liquid adhesive is typically a solvent-based or water-based adhesive.
6. Versatility :
-
Dry cum wet lamination is suitable for laminating a wide range of substrates including paper, film, foil, and non-woven materials.
7. Improved Product Performance :
-
The lamination process enhances the properties of the laminated materials, such as barrier properties, strength, durability, and appearance.
8. Wide Range of Applications :
-
Dry cum wet lamination is widely used in industries such as packaging, printing, labeling, flexible packaging, and specialty applications where high-performance laminated materials are required.
