Frequently Asked Questions About Laminating

Laminating Machines are a standard need in all print houses and a popular office machine and they offer many added benefits to printed material as well as protecting important documents. The world of lamination can be a bit confusing with all the different types of laminators available. However, this FAQ will help you understand lamination, and the different types of laminating machines and hopefully ease the stress when it comes to purchasing laminating machines and laminating film.

1. What’s the difference between hot and cold lamination?
   
   When you think of lamination, perhaps the first thing you think of is Thermal lamination. Hot lamination occurs when a document is encased with laminate (often in the form of a laminating pouch) and is then fed through a machine that melts the adhesive on the film, thus bonding the laminate to the printed material. On the other hand, cold lamination is lamination that occurs without heat.Cold roll laminators use a plastic film which is coated with an adhesive and glossy backing which does not adhere to the glue. When the glossy backing is removed, the adhesive is exposed, which then sticks directly onto the item which needs to be laminated.
2. What is Thermal Lamination? 

   Thermal lamination films bond two sides or more with heat-sensitive film, using heat and pressure alongside the adhesive film will combine the layers. This is a versatile process that can be used on a combination of materials, subsequently leaving a product with a high-quality finish. Additionally, thermal laminate films come at a much lower cost than cold lamination.Thermal films include:
   -BOPP / OPP thermal laminating films
   -PET (Polyester) thermal laminating films

   OPP thermal laminating films has had high growth in recent years, with many benefits of excellent transparency, good resistance to water, chemicals and crack resistance.

3. What’s a pouch laminator?A pouch laminator is a very popular kind of laminator and one of the easiest kinds of laminators to use in offices or copy shops. A pouch laminator can laminate all sizes of documents, including tiny ones (such as business cards) and large, poster-sized items. A laminating pouch is simply a piece of laminate folded in half. You slide your document in, put it through your laminator, and you’re done.
4. What’s a roll laminator?Roll laminators are often found in high-volume printing operations and places that laminate high quantities of printed material. This type of laminator uses two rolls to quickly laminate large items such as posters, book covers, and brochures.
5. What kind of printed material can I laminate? 

   The main purpose of lamination is to protect your documents and make them sturdier. That said, almost any item can be laminated. Some obvious choices would be important personal documents, brochures, annual reports, business cards and menus.

6. I keep seeing the term “mic” What’s that?When buying laminating pouches, you’ll need to think about how rigid you want your items to be once they’re laminated. This is where the term “mic” comes in. “Mic” refers to the thickness of a pouch or laminating film (1 Micron = 1000^th of a millimeter). Pouches and laminating film are available in a variety of micron thicknesses. Essentially, the higher the number, the thicker the pouch or laminating film.
