What are the characteristics of in-mold labeling?

Nowadays, many friends who need to use labels should have a little understanding of in-mold labeling. This labeling mode is very popular now because it has many features. Let us take a look at the uses of in-mold labeling. characteristics. It can be integrated with the plastic bottle during blow molding. The in-mold label material structure consists of a printing surface, an intermediate layer and an adhesive layer. The function of the printing surface is to accept the oil and form colorful graphics and text: the middle layer supports the printing surface, giving the material sufficient stiffness and transparency, and does not deform under the influence of the printing press and high temperature, ensuring accurate overprinting. The adhesive layer melts under the action of temperature, making the label material and the plastic container integrated to ensure that the label and the plastic bottle are firmly adhered together.

 There are two structures on the surface of the adhesive layer: flat non-textured structure and textured structure. The one without mesh structure is in direct contact with the blank during use and naturally exhausts, which is suitable for small-area labels. The reticulated structure refers to an adhesive layer with a reticulated structure embossed on the surface of the adhesive layer. During labeling, the gas between the label and the bottle is exhausted through the reticulated exhaust channels. The generation of bubbles is reduced, and the glue layer also has antistatic properties.

To prevent double sheets from appearing during printing, the adhesive layer should also have certain sliding properties to ensure smooth separation of labels and smooth printing processing.
