The use of a laminating machine, that is, a coating film, not only does not solve many quality problems, but more seriously, it has two major problems that cannot be tolerated.
1 That is, the coating film will cause white pollution. A. The film should not be corroded in the air, and it is difficult to recycle and cause environmental pollution.
B. That is, the film adhesive adheres to harmful objects, which is harmful to human health, and long-term use seriously jeopardizes the worker's body.
2 After the film is coated, it can't be recycled, which wastes resources. Now 80% of the source of papermaking cellulose in China relies on recycling waste paper, including paper edge paper. The amount of paper used in books, magazines, etc. is very large. If we use a large amount of film, especially a film material, and cannot separate the paper from the plastic film, then the paper-covered waste paper and paper edge paper can not be used. Recycling, which will bring immeasurable losses to the country, is actually wasting resources.
That is to say, the contrast between the film and the film can prove that the "heat" of the film should be reduced, and it has reached a level that is not "cold".
