Thermal Lamination Problems

The heat of the laminating machine as it applies the film can cause wet sheets and inks to bubble and begin gassing resulting in air being trapped between the laminate and the printed sheets.

Thermal lamination problems.

Use the right temperature check the pouch s specifications on temperature. Increase the laminating speed just as high speed is bad low speed is also bad as it can cause the pouch to heat up. Another lamination process uses a lamination press after materials are combined in a thicker structure than film. With water based or solvent based ink systems uncured inks can create several challenges when the sheet is being laminated with a thermal laminating process.

Lamination is all about getting two materials to bond together. 1 1 the film will wrinkle if there is not enough supply roll tension. The biggest pitfalls for laminators has been the same one that has dogged converters since the dawn of well lamination. The same principles apply to cold laminates.

The laminators have scotch printed on the front. Having the right set up right from the start. They are used to laminate documents such as artwork and photos. As an example azdel a glass reinforced thermoplastic composite made with continuous glass mat is produced using an extrusion lamination operation film continuous random orientation glass mat and molten resin are combined in a lamination process using a sandvik double belted.

Any laminator needs a certain amount of resistance to the unwinding of the supply rolls so that the film lays flat as it goes into the nip of the laminating rollers. For laminators that have adjustable temperature settings simply increase the temperature in small increments until the cloudiness disappears. If there aren t any recommendations on. Silvering is caused when the adhesive not wetting out properly this problem is solved by either increasing the temperature setting or slowing down the speed setting.

This will promote a better adhesive flow. Turn the rolls of film supply rolls in the unwind direction. The model number tl901c is printed on a sticker on the bottom of the laminator. If you have run the pouch through your pouch laminator and it still has a milky look to it it is most likely an indication that the laminating temperature is set too low.

If you don t manage the contact point well air bubbles will get trapped in the middle. Is there some resistance. They measure 14 inches by 3 8 inches by 2 75 inches.
