Film for laminate paper, foil and nylon bonding

In the paper and packaging industries, laminating film is applied to surfaces such as paper, cardboard, aluminum foil and biofilm. The purpose of laminating film is to provide food and non-food packaging with barrier properties, improved appearance and haptic properties which contribute to the “feel” of a surface.

Laminating films and applications exist as numerous types each of them suitable for specific processes. BOPP, nylon and PET laminating film applications are the most common. The different lamination film types are generally suitable for wet bonding and thermal lamination film applications.

Lamination: how to laminate paper, meaning and film types

Adhesive lamination is the process of joining two or more flexible webs together assisted by a bonding agent, usually an adhesive. The substrates making up the webs can be paper film, biofilm or aluminum foil. The adhesive is applied to the less absorbent substrate, and the other web is pressed on it to create two layer laminate.

Lamination exists primarily as two different processes which both use special films made for them: wet lamination and thermal lamination. Here we will take a closer look at the wet lamination and thermal laminating films.

PET laminating film – Biaxially oriented polyethylene terephthalate

Another popular, yet little more expensive laminating film is based on biaxially oriented polyethylene terephthalate – PET. The PET laminating films are also known as polyester films. The PET laminating film is generally used for two-sided printing.
