Polyester (PET) Thermal/Hot Lamination

PET hot laminatorswork with rigid film with thicknesses from 30 micron to 250 micron. Polyester laminators involve the use of heat shoes or heated rollers. PET laminators are suitable for a range of documents, including posters or smaller items such as membership cards. The edges produced by a PET hot laminator can be trimmed flush or feature an encapsulated finish. If using synthetic stock, documents trimmed flush are still waterproof, which is perfect for membership cards for pools or gyms. Some companies even make use of low micron PET in packaging due to its heat and water resistance.

A laminator pouch will usually be made of PET. A polyester laminator must use both top and bottom rolls to work properly. The ideal running temperature of a PET laminator is between 110 and 120 degrees. Polyester film can come in gloss or matte finishes.

Polypropylene (BOPP: Bi-Axially Oriented Polypropylene) Thermal/Hot Lamination

This film made of polypropylene is a lot more flexible and can be used on covers, packaging, cards and many more applications. The width of the film can be between 25 and 42 microns and it can be used single or double-sided. It’s a kind of hot lamination as it needs to be used with heated rollers to allow proper adhesion. Various types of film are available to suit the kind of printing process used, either offset or digital. Printing in digital format will require a stronger adhesion on the part of the polypropylene film, and so will need a different kind of film than that used for offset printing. BOPP can be found in finishes such as gloss, matte, anti-scuff and soft-touch.

Cold Film Laminating

Cold film is made of PVC and has a backing that’s pressure sensitive. The process of a cold film laminator involves the use of a roller pressure action. This kind of laminator is perfect for large format print laminating. Cold film can be found on the market in monomeric or polymeric vinyl and cast. Cold film laminators create products that are UV treated and resistant to weather elements.
