Raw materials for adhesive labels

The raw materials of self-adhesive labels mainly include facestock, adhesive, and release liner.

The facestock is the visible surface of the label and the part we directly see and touch. The choice of facestock is diverse and can be selected according to actual needs. It usually includes various types of paper (such as coated paper, bond paper, thermal paper, PET, PVC, etc.), or plastic film (such as polyester, polyethylene, polypropylene, vinyl, etc.). These facestocks can meet the printing needs of various labels, such as thermal transfer, thermal printing, laser printing, and can withstand various post-processing, such as lamination, die-cutting, punching, etc.

The adhesive is a crucial component of the self-adhesive label, allowing the label to stick firmly to the product. There are many types of adhesives, including water-based glue, hot melt adhesive, solvent adhesive, silicone adhesive, etc. These adhesives have their advantages and disadvantages, and can be selected according to the purpose of the label, the surface material of the paste, environmental conditions (such as temperature, humidity, etc.), and the specific needs of customers.

The release liner, also known as backing paper, is mainly used to protect the adhesive and plays a crucial role in label printing and labeling process. Commonly used release liner materials include glassine paper, PET film, etc., which have excellent smoothness and stability, and can maintain good operation on various printing equipment.

The choice of raw materials for self-adhesive labels is very important, directly affecting the quality and application effect of the label. Therefore, when choosing raw materials, it is necessary to consider the purpose of the label, the surface material of the paste, environmental conditions, and the specific needs of the customer.

The raw materials of self-adhesive labels need to consider not only their characteristics but also their compatibility with other materials, such as the compatibility of facestock with adhesive, adhesive with release liner, to ensure the overall performance and quality of the label.
