Laminating paper is produced by using raw paper and PE material. The coated paper has two kinds of hot film and cold laminating. The hot film is thin, the light transmission is good, the storage time is long, the requirements for photo paper are low, printing and printing. Photo paper can be used but relatively high cost, and the film can not be removed once the film fails. Laminating paper is a composite material that coats plastic particles on a paper surface by a casting machine. The main feature is that the composite material can be oil-proof, waterproof (relative), and heat-sealable. The differences between the two are mainly the following:
1. Cleanliness refers to the cleanness and cleanliness of the surface. Because the production environment of the release paper manufacturers is not the same, most of them are not dust-free studios. Due to the cost problem, it is impossible to use a dust-free studio. Generally speaking, it is an ordinary factory building. A little better, there will be many improvements in environmental protection and environment, which will have an impact on cleanliness.
2, the degree of release, refers to the degree of release of the release paper, the correct value at this point, depending on the formula of each manufacturer to decide.
3. Peeling force, peeling force refers to whether it is easy when the product is torn off. Of course, this has strict testing standards.
Laminating paper and coated paper Different uses take different characteristics: When used to package burgers, take their oil-proof properties. McDonald’s is an 80-degree edible vegetable oil that does not leak oil for 10 minutes. When used in coated paper, it is waterproof. When used in automatic packaging machine packaging, take its heat sealing characteristics.
