Today I will tell you about the repair and maintenance of the blister machine. It doesn’t matter if you don’t understand it like this, so let me follow the editor of Shenzhen Yonghengsheng Blister Machine.

 

            The oil printed on white paper or white cardboard can be heated to the melting temperature by the blister machine to blister and coat the plastic film. Paper layer bonding. It is an enlarged schematic diagram of the packaging structure; when the packaging is torn apart, the damaged interface should be inside the paper layer 5. As long as the plastic film sticks the paper layer up, the packaging is considered successful, so coating the whiteboard (card) paper coating The strength must be higher than that of the paper layer to satisfy the functional requirements of the packaging. The factors that cause uneasiness are often because the damaged interface does not occur inside the whiteboard (card) paper layer.

 

            The specific situation requires specific analysis. (1)—When the package is opened, the damaged interface occurs in the oil layer (shown as the peeled plastic film without ink), which indicates that the outer coating of the paper is tightly closed and the oil is difficult to penetrate into the paper layer.

 

            (2) When the blister machine tears open the package, the damaged interface occurs in the ink layer (shown as the peeling of the plastic film with ink, but the peeling of the paper hair is less), indicating that the strength of the paper coating is lower than that of the paper layer, which may be The amount of paint latex is not good, the connection between the base coat and the top coat is not good, and the relocation of the adhesive causes uneven coating strength.

 

            (3) When the package is torn apart, the damaged interface occurs on the surface of the whiteboard (cardboard) paper coating, indicating that the strength of the paper surface coating is low and the coating is tightly closed, and it is difficult for oil to penetrate the paper layer.

 

            (4) When the package is torn apart, the damaged interface occurs at 1/2 and 1/3 of the thickness of the whiteboard (card) paper, which shows an excellent effect.

 

            Based on the above analysis, the factors affecting the effect of water-based oil can be summarized as follows: paper, water-based oil, printing technology, technology, etc.
