MEFU Roll laminator is an emerging advertising screen laminating machine, that is suitable for finishing all kinds of airbrushes, prints, photographs, banners, and so on.

Difference between cold laminating film and hot laminating film?

Cold film and hot film are laminating materials that need to be used in the laminating machine because the laminating machine is divided into cold laminating machine and hot laminating machine, so there is a difference between the laminating materials.

1.The cold laminating machine adopts cold glue laminating technology, which applies glue on the glue roller, evenly spreads the glue on the laminating material with pressure, and then directly cold presses the laminating material with the printed material.So, the cold glue laminating machine does not require heating during operation, which can save heating time and improve production efficiency.

2.The hot laminating machine adopts hot melt adhesive lamination technology, in which the hot melt adhesive needs to be heated and melted, then coated on the laminating material.The laminating and printing materials are combined on the heated glue roller using pressure and then cut after cooling. This type of machine requires heating during the composite process, so it requires heating time and has relatively low efficiency.

3. Cold lamination is the process of using the pressure of glue and a cold laminating machine to bond photos with film and backing. Hot lamination relies on the high temperature and high pressure of the hot laminating machine to complete the mounting of photos. In contrast, the cost of cold lamination is lower, but the effect of hot lamination is better, and the storage time of photos after lamination is also longer.

Which is better, cold laminated film or hot laminated film?

Cold laminated and hot laminated films are widely used in the market, and there is no distinction between good and bad. When choosing, we only need to choose the one that is more suitable for ourselves according to our own needs.

1. Scope of application

Cold laminator is suitable for laminating prints with thin thickness, including books, banners, posters, and so on. As the glue applied is very thick, the prints after laminating have high waterproof and abrasion resistance.

Hot laminator is suitable for laminating materials such as paper or boxes with large thicknesses, which can improve the gloss and texture of the prints, but the waterproof and abrasion resistance of the prints after lamination is poor.

2. Cost of use

Cold laminating machine consumables are mainly cold glue, you can use the cheaper glue for laminating, the use of relatively low cost, and because there is no need to heat, eliminating the cost of heating.

The hot laminating machine requires hot melt adhesive, in the process of laminating needs to be constantly heated, the cost is relatively high, while heating will also produce a certain amount of waste heat and harmful gases, causing a certain impact on the environment.

3. Use photo lamination as an example

As the back of the film of the hot laminating film is coated with a dry adhesive, when it is laminated with the printed material into the hot press laminating equipment, the adhesive, due to the action of heat, will be posted to the printed material and the film under a certain pressure, and then it will be firmly molded immediately after cooling. Compared with cold laminating, hot laminating equipment is more expensive.

If the paper substrate or ink will be deformed or damaged by the heat pressure, it is necessary to use cold laminating technology. Cold laminating technology is required. Cold lamination has no adhesive on the back of the film and is generally only suitable for one-sided lamination.

Cold lamination needs to be first in the printed surface coated with aqueous adhesive, and then sequentially into the laminating equipment with a roll of film, when the film and the printed surface of the adhesive on the completion of the entire laminating process, but it takes a few days to dry naturally, to be firmly shaped.

Conclusion

In summary, cold laminating machine and hot laminating machine have their advantages and disadvantages and need to be chosen according to specific needs. If you need to laminate thinner prints, you can choose the cold laminating machine, which uses low cost, and high efficiency; if you need to improve the texture of prints with greater thickness, choose the hot laminating machine.

The MF1700 series laminators are capable of laminating at speeds of up to 8 meters per minute using either low or high-temperature cold adhesive or hot laminating films, making them the ideal commercial laminating solution.

MF1700 can be used with either hot or pressure-sensitive cold films to achieve single- or double-sided hot and cold lamination. If you are not sure whether you need a cold or hot laminator, choose the MEFU MF1700 series for your multiple needs!
