Laminating machine before use coated inspection | fumo machine has high precision
Ruian Jialite Printing and Packaging Machinery Co., Ltd. specializes in the production of high precision laminating machine, non adhesive laminating machine and other products.
After adjusting the laminating machine, the pretreated printed matter is fed into the paper feeding mechanism for laminating, and the sample is obtained for inspection. Before the film with a small amount of printed matter for inspection, so as not to cause a lot of waste, after inspection, you can carry out mass production. The use method of film covering test is as follows:
1, the film-covered sample film-covered corner to the wide direction of the tear, press and hold the paper, the width of the direction of all tear, in all tear, tear, if print surface text blot with adhesive layer and paper fiber transfer to the film, then print and film bonding is good, qualified products.
2. Put the coated sample into the baking channel, bake at 60~65 degrees Celsius for about 30 minutes, if there is no foaming phenomenon, no delamination, wrinkle-free, qualified products. After baking, tear off the film should not be intact and paper separation.
3, put the sample into cold water soak for 1 hour after taking out, such as plastic film and printed matter is not separated from the qualified product.
4, put the sample on the indentation machine pressure, such as the concave and convex part of the pressure is not delamination is qualified products.
