Laminating is one of the easiest and most cost effective ways of preserving and protecting important files. From menus and price listings to posters and children’s art work, laminating has applications in a wide range of businesses and industries. When it comes to laminating film, roll laminating film is the least expensive and most versatile choice, but selecting the right rolls for your device and your specific needs can seem a bit overwhelming. In this post, we’ll take a nearer look at roll lamination film and learn about the various styles available on the market today.
Most roll laminating movie is thermal (requiring heat to achieve a proper seal) and made from polyester, though there are specialty films that utilize other application processes, for example pressure sensitive film, or materials, such as nylon film. When purchasing roll laminating film, there are four important factors to consider: core size, film grade, roll width, and film thickness. There are other variables to keep in mind, such as film finish (including clear plus matte varieties) and roll duration, however these are less critical than the other factors.
Being aware of the important thing variables (core size, film grade, roll width, and film thickness) between different roll laminating films will help you avoid purchasing film that is incompatible with your roll laminating device. The core size corresponds directly to the size of the mandrel that holds the film on the laminator.

You can find three standard core sizes: 1″, 2-1/4″, and 3″. The size of the core often correlates to the entire roll, since a longer roll requires a thicker mandrel to support it.
The particular film grade indicates the quality of the particular adhesive that is used to affix the laminate to the document. Standard film (also called “school film”) is really a low-cost material that is ideal for laminating standard 20lb paper with gentle ink coverage. Pro-grade film is designed for professional use, with a lower burning temperature and more aggressive adhesive which makes it a good choice for digital or offset printing. Additional film grades are available on the market, including low melt (which has a reduced melting temperature), SuperStick (which has an increased adhesion strength), pressure sensitive (which uses non-thermal adhesives), and nylon (which is designed for single-sided applications), however they are significantly more expensive and are not compatible with just about all roll laminators.
The roll width represents the width of the laminating film, and is dictated by the size of the machine itself. Rolls can be found in standard sizes as narrow as 9″ and as wide as 60″. Roll laminators cannot use films that are wider than their specified maximum widths, however they can use progresses that are narrower, which means that you can minimize waste when running smaller paperwork by purchasing appropriately-sized film rolls.
Such as laminating pouches, roll laminating movie is sold in a range of thicknesses, since thin as 1 . 5 mils and as thick as 10 mils. This metric represents the combined thickness of the film and backing that makes up a single layer associated with laminating film. Similar to pouch laminating machines, roll laminators are designed to support specific film thicknesses, so it is essential to use only the film that your machine can handle. Attempting to laminate with movie that is either too thin or as well thick will result in improper adhesion and can potentially damage your machine.
Selecting the Right Film
Roll laminating film is often categorized by film grade and/or core size. Once you’ve navigated to the section that corresponds to the movie you’re looking for, you’ll see that each film move is listed with three dimensions (such as 25 in. by 500 ft. x 1 in. ). The first number represents the roll width, the second number means the roll length, and the final measurement indicates the core dimension. In the case of the example, the move width is 25″, the length is 500′, and it has a 1″ primary size.
Because of all of the variables involved, there are literally thousands of roll laminating films on the market today. Consequently, locating the rolls that work with your machine and are appropriate for the type of laminating that you are doing can seem confusing. Knowing a number of key details, namely the core size, film grade, roll width, and film thickness, will make selecting the proper film much easier. Most of these details is listed in the owner’s manual for your machine, or can be located by doing an internet search using the design number of your laminator. Spending the time to learn about your machine will not only save you time in selecting the right film, but will even help you avoid the costly mistake of purchasing film that is not compatible with your laminator.
