Choose from the type of release material

Simple release release material from the film and release paper is divided into two categories.

Introduction and release paper application:

Release paper, also known as silicone paper, release paper. Isolated major role to play with a sticky objects, such as tape. When using the general need to be stripped, discarded; now have a wider application, mainly with Polystyrene carrier tape or, of course, food, health industry applications not described in detail here.

Release paper Category:

Release paper classification, can have plastic and non-plastic release paper release paper classification; press release agent can also be classified silicone release paper and non-silicone release liner.

There are plastic release paper as release agent has a certain permeability, if not necessarily a barrier, release agent will penetrate into the paper inside, resulting in poor curing agent from the type and the amount is too large (too expensive) and many other bad factor. So they need to do on paper, plastic processing (commonly known as lamination), domestic general use polyethylene (PE) particles Laminating, requires a melt index of about seven, domestic PE particles are generally used in Yanshan Petrochemical 1C7A. Divided into single and double plastic plastic release paper release paper; no plastic release paper, mainly glassine, CCK and other specially treated other release liner.

1. Laminating release paper

After lamination paper after the lamination surface coating release agent, derived from the release paper production.

Because the paper surface paper hair and fiber, so Laminating must go to a certain amount, in order to ensure that no infiltration points, in order to ensure the silicone oil will not penetrate into the paper, in order to ensure there will be no adverse peel. Generally coated paper lamination amount of 16 grams per square meter, is said to have done in Wenzhou 11 to 13 grams per square meter, very close Laminating data of foreign advanced equipment. In theory, as long as they ensure the release paper from the tape stripping, and then lower the amount of lamination are permitted.

Laminating release paper is divided into single cream and double cream. Generally sided release paper is a single shower, of course, there are double-sided release paper shower, because from the type of surface is generally thicker lamination 20 grams, leave-surface generally thinner 15 grams, this release paper compares smooth. If the amount is double-sided lamination are 22 grams of coated paper, is more suitable for double-sided release paper. Laminating release paper generally use all wood pulp paper, especially in the electronics industry. If you use grass pulp and paper, at the time you have a lot of die-cut paper scraps and easily broken edges. All wood pulp paper commonly referred to as kraft paper, such as brown kraft (commonly known as: The cow), white kraft paper (commonly known as: white cow), yellow kraft paper (commonly known as: Japanese yellow color cow), blue kraft paper (commonly known as: Indonesian blue color cow). Of course, the whole pulp offset paper is also useful to make paper, and more to do with the photographic paper base paper, and the paper used to make coated paper and paper board, cow cards, milk, paper cards, etc.. As long as lamination of paper and plastic fastness to meet the requirements, as long as there is no penetration point lamination, lamination smooth, and it should say what can be done on paper base paper.

2. Glassine release paper

Glassine paper by overpressure after coating release agent, release paper production derived. Because after super calendered glassine paper firmness good, especially for die-cutting factory use.

Since domestic production glassine only 60 to 80 grams of quantification, and die-cutting factory prefer to use 100 grams or more quantitative, such as 120 g, 140 g. With a certain degree of transparency, good stiffness, cutting performance and good. All rely on imported paper, but due to imports from the quantitative paper is 20 tons per container, and must be scheduled in advance three months, orders to pay the full amount. There are many domestic release coating suppliers do not feel any great significance.

3. CCK release paper

CCK paper is coated with a surface layer of special clay coating after release agent, derived from the release paper production. Because of its high temperature performance is particularly good, is widely used in the carbon fiber industry.

CCK paper clay surface and is easy to destroy organic silicon, so domestic production of CCK release paper can really pass is still a minority.

4. Other release paper

There are also some release paper is widely used in many industries, but also do not use release agents. For example, label printers tend to be in need to have a place away from the layer of varnish on the type, the release will have some ability, of course, to be the glue weak performance. Otherwise, this is from the type of capability is also futile. While others, such as the use of some special glue formula production release paper and the overall market share very little. Currently the electronics industry use genuine paper (through regular factory production, a stable supply of quality assurance and release paper) less, mainly garbled paper (used once abroad, or from a faulty release paper) based . Glue factory is basically using the genuine paper.
