The versatility of industrial roll lamination is largely due to the variety of configurations laminators can achieve. There are two primary types of roll laminating: hot and cold.
- Hot Roll Laminating: This method is known for producing durable goods and can be highly efficient when properly set up. It is ideal for items that can withstand heat during the lamination process.
- Cold Roll Laminating: This method is preferred for goods that are sensitive to heat, as it does not involve high temperatures. Cold roll laminator machine can also be more user-friendly, making them easier to operate.
In a heated roller laminator, melted glue is applied to the film using hot rollers. The process involves two rollers: one positioned on top and the other fixed at the bottom. The glue is in a liquid state when heated and solidifies upon cooling, adhering the film to the material. This type of laminator is highly flexible and commonly used in large-scale production environments, such as printing houses or print finishers, to laminate items like paperback book covers, magazine covers, posters, cards, and postcards. The advantages of heated roller lamination include faster processing speeds, lower costs compared to cold roll lamination, and better quality and durability of the laminated products.
The choice between hot and cold lamination machines depends largely on the types of documents you plan to laminate. Cold lamination is ideal for heat-sensitive materials, such as photos, glossy paper, and inkjet-printed business cards. Unlike hot laminators, cold lamination machines do not use heat, making them suitable for delicate items that could be damaged by high temperatures.
The laminating process is a post-printing surface processing technology, also known as post-printing plastic, post-printing glue, or post-printing film. It involves using a laminating machine to cover the surface of a printed product with a thin transparent plastic film, typically 0.012 to 0.020 mm thick. This process results in a paper-plastic integrated product, offering both protection and decoration.
Laminating is a significant part of post-press processing, widely used to enhance and safeguard printed materials. If you visit a bookstore, you'll notice that most books have laminated covers. This is because the lamination process makes the surface of the printed material smoother, glossier, and more resistant to stains, water, and abrasion. Laminated covers are more vibrant and durable, offering better protection against wear and tear. The process also significantly improves the printed material's resistance to abrasion, folding, tension, and moisture, thereby extending the product's lifespan.
One of the most notable advantages of lamination is its ability to compensate for quality defects in printed products. Many visible flaws that occur during the printing process can be concealed with a film, especially with matte film, making the final product appear more polished and professional.
Durability: Laminated materials are more resistant to damage, extending the lifespan of printed products.
Cost-Effectiveness: For large-scale lamination projects, autofeed roll laminators are more economical compared to other methods.

1. What materials can be laminated?
Most paper-based materials, photos, and even some fabrics can be laminated.
2. How do I choose the right laminating film?
Consider the thickness, finish, and specific application needs when selecting a laminating film.
3. Can laminated documents be recycled?
It depends on the type of film used. Some eco-friendly films are recyclable.
4. What are the common issues with roll laminators?
Common issues include film jams, air bubbles, and uneven lamination.
5. How do I maintain my laminating machine?
Regular cleaning, proper storage of laminating films, and following the manufacturer's maintenance guidelines are key to keeping the machine in good condition.
There are dozens of laminators out there ranging in size, functionality and price. That’s why we’ve put this helpful guide together—so you can make a smart decision.
Pouch laminators are the most commonly used laminator type worldwide. You take your document, put it in a pouch, and the machine does the rest.
Roll laminators excel in speed and flexibility. If you deal with larger volumes, odd sizes and demanding deadlines, it might be your best choice.
No Matter the Type, Consider These Factors
Not all laminators cover every format. And while other aspects are important, document size is critical. If you laminate standard dimensions – like letter-sized documents – a pouch laminator is probably right for you. Roll laminators cover larger sizes, from 27" down to 9", giving you more flexibility.
Laminating pouches are measured in millimeters (mm). They range from 3–10mm and cover all paper sizes. As a general rule, the more the document is handled, the thicker the laminate should be.
For roll laminators, the film ranges from 1.5–3mm and comes with an enhanced glossy finish. We offer two types of roll film – standard roll film and EZload film, available in a variety of lengths.
Tip: Loading the film upside can cause the film to be “glued” to the heat rollers. This is the number one reason we get service calls for laminators. EZload solves this issue.
The number of users has a significant impact on choice. Pouch machines are ideal to keep at your desk or at reception, while a roll laminator is best suited for a shared work space.
Need a laminator that runs as fast as your workspace? Our Ultima 65 laminator comes with an AutoSpeed feature. The machine always runs at the perfect speed, ensuring the best possible lamination output every single time.
Pouch laminators are popular, and are simple to use, but roll laminators can be simple, too. We’ve developed our own film and features, making laminating a quick and painless process.
A laminator is an investment. When choosing, consider its frequency of use and also factor in laminating accessories. These are often overlooked when considering overall cost.
