Wide format hot laminating machine

Types of wide format hot laminating machines

A wide format hot laminating machine is an equipment that adds a protective layer of plastic to documents, prints, and other items. Such items are typically placed between two plastic films and heated until laminated. Laminating machines do not laminate on their own; they need to be part of a hot and cold lamination system operated by a wide-format hot and cold lamination machine. Cold adhesive is pressure-sensitive and used to glue something down without heat. Sheet or roll lamination can be done with or without heat.

Using heat and pressure activates hot adhesive, which sometimes requires heat and high pressure to work correctly. Hot adhesive can be used to laminate things like foam boards, duck canvas, fabric, optically clear BOPP, and more. It works better to use heat instead of cold when laminating wide-format things. Another difference between cold and hot laminating machines is that a cold laminating machine does not require heat but can only use pressure to activate adhesive. This means that cold laminating machines can use films that require pressure to activate, which are mostly pressure-sensitive adhesives.

Rotary (or roll) laminators are generally considered cold lamination machines because they pressure rollers to push the film down on top of the graphics. Standard encapsulated films used for cold laminating have pressure-activated glue on the inside that sticks to the graphics when pressed down with the laminating film and roller pressure. On the other hand, hot laminating machines are commonly pouch, belt, and roller transformers that use heat to activate film glue and stick to unlaminated objects.

Users can laminate oversized object parts in the wide-format category, like banners, posters, and other displays. Design details like the type of lamination used are also essential. For large items, encapsulation is preferable to non-encapsulation because the encapsulation film goes over and encases the print all the way around. This allows for a clean and very simple peel from the non-encapsulated film. Non-encapsulated films can also leave a film line around the printed piece when removed.

Specifications and Maintenance

Key specifications to consider when purchasing a wide-format hot laminating machine include the type, roll width, temperature control, and speed.

• The machine's construction determines the type of lamination the item will receive. A pouch laminating machine is suitable for small projects using laminated pouches. Cold and hot laminators are used for various applications and typically utilize different types of films that are activated under heat.
• Hot wide-format laminating machines are available in various roll widths, typically ranging from 160 mm to 1,600 mm. The laminating width needs to be broader than the item being laminated for successful lamination.
• The precision of temperature control is important because different types of laminate films require specific activation temperatures. The wide-format hot laminating machine has an adjustable temperature setting that allows the operator to control the temperature exactly.
• Laminating speed is the rate at which the item is pulled through the machine and laminated. It is measured in mm/min or inch/min. This specification is essential for large-volume projects where efficiency is a priority.

Like any piece of equipment, performing routine maintenance will help the machine operate efficiently and improve its lifespan. The wide format hot laminating machine requires cleaning, oiling, and film replacement.

• Cleaning the machine involves removing dust and debris using a dry or slightly damp cloth. Cleaning rollers with a designated cleaning cloth and solution will remove residue and avoid dirty marks on laminated items. A cleaning card can be used to clean the laminating machine's rollers and internal components.
• Parts of the machine that move and rollers will benefit from a small amount of oil occasionally. Lubricate moving parts sparingly with a suitable lubricant.
• When the film gets jammed or tangled up, or any part of it is worn or damaged, it's time to replace it. Before replacing the film, ensure the film is compatible with the machine.
