Classification of release paper, release paper and plastic can have no plastic release paper category, you can also press the release agent classification. Silicone release paper and non-silicon release paper.
There are plastic release paper, because the release agent has a certain permeability, if not necessarily a barrier, release agent will penetrate into the paper inside, resulting in poor curing and the amount of release agent is too large (too expensive), and many other adverse factor. So we need to do on paper plastic processing (commonly known as lamination). Domestic general use polyethylene (PE) particles lamination, requires a melt index of about 7, domestic PE particles generally used Yanshan Petrochemical 1C7A. Divided into single and double plastic plastic release paper release paper, no plastic release paper 'main glassine, CCK and other specially treated other release paper.
Selection of release paper
Because the amount of coating directly affect the applicability of the glue. Water gel silicone coating require a lower amount, while higher oil and hot melt adhesive silicone coating amount required. Its larger penetration destructive, are generally high volume coating.
Glue factory generally use a high amount of coating release paper, and composite plants generally use moderate amount of coating release paper, if the thermal compound, it would need to choose a high amount of coating release paper, protective film ( water glue) requires only a low amount of coating release paper can be. Moderate amount of coating release paper for oil plastic protective film, a high amount of coating release paper is not suitable for protective films.
Because of the relationship between climate, the plants die in winter should be chosen emphasis peel force of the release paper, summer should choose lighter peel force of the release liner.
Some of the special needs of the tape, the release paper used in the die-cutting process, the need and the release coating supplier contact. Do depth testing, production activities can be carried out after comparison. Otherwise it will produce a lot of waste.
Garbled paper is not can not be used if it is less demanding place, can still be used, otherwise the country would not have so many garbled paper supplier a.
