What Is a Laminating Film?

Posted by Admin
Laminating films are used to provide a protective barrier to a printed item. This helps protect from damage due to water, stains, and creases. They are available in a variety of styles and thicknesses. A thin film is typically preferred on curved or uneven surfaces.
Most laminating films are made from Polyethylene Terephthalate (PET) plastic. However, some types are also made from nylon and bi-axially oriented polypropylene. These two materials can be recycled.
Thermal laminating is a process that uses special films to create a protective bond. It is applied to a document and then processed through a heated roll laminator. It gives a professional finish and provides a long-lasting bond.
Pressure-sensitive adhesives are often used in the lamination process. The adhesive sticks directly to the surface being laminated. They can be activated by heat, high-pressure, or both.
When selecting a laminating film, it is important to consider the size and width of the machine. Some may only support one type of film. If your machine is too small to accommodate a longer film, you can trim the excess to fit.
Most businesses use a one-inch core for most laminating films. But some laminators can handle varying core sizes.
The thickness of a laminating film plays an important role in how easy it is to laminate. Thin films are best on uneven or curved surfaces, while thicker films are more suitable for flat graphics.
