What is the Difference Between Adhesive and Extrusion Lamination?
During adhesive lamination, a single film material is coated with adhesive and then laminated onto a second film. Typically, this lamination process is repeated until the films are completely processed, creating a unique flexible packaging lamination in a range of shapes and colors.
Extrusion lamination, on the other hand, binds two films together using a molten resin which then creates the multiple layers. Because of the inaccuracies of this technique, however, Bison Bag does not provide extrusion laminated bags.
Adhesive lamination, using multiple adhesive on multiple layers of film, provides better protection for the products inside the bag, and enables better and more durable flexibility over a longer time, creating a superior product with more cost-effective methods.
What is the Difference Between Lamination and Bonding?
Lamination and bonding are often used interchangeably, but each refers to a unique process of combining materials. Lamination, in this case, refers specifically to the method of layering thin layers of film and adhesive together to ‘bond’ materials together.
While this enhances the durability and flexibility of your packaging, lamination is not the only type of bonding. Bonding often refers to a range of techniques that can include sewing, glueing, and welding. Depending on the materials being used and the use-case of the packaging, lamination is often preferred as it is much more precise and uniform. This is particularly true in industrial applications, such as packaging.
