Printing on the surface of the film material is often encountered in the label printing industry. Because the film material does not absorb ink, the ink layer is attached to the surface of the film only, so the firmness and scratch resistance of the ink layer are the key factors to ensure the quality of the label printing.

 

In practical application, the ink fastness of the film label is in accordance with the standard, but the problem of scratch resistance of the ink layer is still not solved. For example, some domestic cosmetics customers, the plastic bottles after their labeling are often placed directly into the packing box, and there is no partition or filling between the bottle bodies, and then shipped to all places, which makes the bottle body easily collided and frictional in the process of transportation, and eventually leads to the serious wear and tear of the ink on the surface of the bottle. Goods can not be sold normally.

 

In order to solve the problem of the wear of the ink layer, in addition to the brand business to make changes in the way of product packaging, the printing enterprises usually use three other methods: screen printing directly on the packaging bottle, using the thickness and strength of the ink to improve the wear degree of the ink layer. The composite BOPP film is used to protect the ink layer; the UV polishing process is used to protect the ink layer on the surface of the film material.

 

After a comprehensive comparison, Xiaobing of POF thermal shrink film Co., Ltd. thinks that UV polishing process is the most ideal solution.
