A laminating film is a translucent material made of a thin layer of plastic used for sandwiching documents or cards to seal and preserve their condition (lamination). It is sealed using heat or pressure. It is used with either hot or cold lamination depending on the type of document to be laminated. It is available in different widths and thickness.
Types of Laminating Films
Kinds of Laminating Films include the following:
Standard thermal laminating film
A standard thermal laminating film is a polyester film that bonds between the temperatures of 210 and 240 degrees Fahrenheit.
It consists of polyethylene adhesives commonly used in films and photography.
Liquid film laminating film
This type of laminating film uses liquid coatings such as solvents and aqueous medium.
It requires a special liquid coating machine to sustain the process.
Pressure sensitive laminating film
A pressure sensitive laminating film is made up of polyvinyl chloride or polyester, which has an acrylic adhesive base.
The composition of its adhesive base varies depending on the manufacturer.
It is also called a cold laminating film.
It does not require heat to bond; it only needs sufficient pressure from pressure sensitive techniques.
Low temperature thermal laminating film
This type of laminating film is similar in composition to the standard thermal laminating film, but it also made of polyester with a polyethylene adhesive.
It bonds at low temperature usually between 185 and 210 degrees Fahrenheit.
It is currently being developed to replace the standard thermal laminating film.
Heat assisted laminating film
This type of laminating film is also called a heatset laminating film.
It is a polyvinyl chloride or polyester based film.
It uses a fully thermoplastic adhesive.
It requires a temperature between 170 and 195 degrees Fahrenheit to bond to the substrate during the lamination process.
Choosing Laminating Films (Buying tips)
Size: If you want an inexpensive laminating film, choose a 1.5 mm laminating film, which is ideal for short-term lamination. If you want excellent long-term protection, on the other hand, choose a 3.0 mm laminating film that does not easily curl, wrinkle, or wave.
