Film inspection before running the semi-automatic laminating machine

After the semi-automatic laminating machine is adjusted, the pre-processed printed matter is fed into a paper feeding mechanism for lamination, and samples are taken for inspection. Before the film is covered, a small amount of printed matter is used for inspection to avoid a large amount of waste. [  Semi automatic lamination machine  ] After the test is passed, large-scale production can be carried out.


The film inspection method is as follows:
1. 
The semi-automatic laminating machine peels off the corner of the sample film which is completed by the film in the width direction, presses the paper, tears all the width direction, and after all tearing and tearing, if the surface of the printed matter is imprinted with the rubber layer The transfer of the fibers of the paper to the film indicates that the printed matter adheres well to the film and is a qualified product.

2.
Semi-automatic laminating machine put the coated sample into the drying tunnel, baking at 60 ~ 65 degrees Celsius for about 30 minutes, if there is no foaming, no delamination, no wrinkles, is a qualified product. [ Manual Lamination Machine ] The film peeled off after baking should not be separated from the paper.

3. 
The semi-automatic laminating machine takes the sample into cold water for 1 hour and then takes it out. If the plastic film and the printed matter are not separated, it is a good product.

4. 
The semi-automatic laminating machine puts the sample on the creasing machine and presses it. If the concave and convex parts are not delaminated, it is a good product.
