Something about Adhesive Labels Roll Material

At present, there are many kinds of adhesive labels roll materials, mainly from the three components of dry glue, namely: surface materials, pressure sensitive adhesives (adhesives), substrates (commonly known as silicone oil coated detachable substrates). Different fabrics, pressure sensitive adhesives and substrates can be combined with many label materials.

Non-professional users often only pay attention to the selection of fabrics, because they can directly show the design and visual effects. In fact, what is the most important quality adhesive labels roll material is hidden in the "face" under the adhesives and substrates. After all, before the label finished products leave the factory, the quality of the fabrics is easy to be checked in the middle layer of pre-press, printing and finished product inspection, so that the loss of users is small. However, adhesives are susceptible to labeling or use environment (temperature, humidity, etc.). Different properties of the adhesives also have different choices for adhesives. Usually when labeling, or sticking with the object for a period of time, or even a considerable period of time, the adhesive problem will be exposed, causing the greatest loss to users, serious glue overflow will damage the printing equipment; Poor coating of low-grade substrate or silicone oil will also expose the use problems such as cutting and piercing, flying mark, non-marking, paper jam, etc., which will also cause great losses to users.

The main types and characteristics of pressure sensitive adhesives on the market are as follows:
(1) Solvent-based adhesives: Dissolved in solvents, economical, and more suitable for various use environments, but with greater toxicity to the human body. It has been banned in developed countries in Europe and the United States. At present, it is still widely used in wet paper towels, sanitary napkins, daily chemical products and even food labels in China.
(2) Emulsion-type adhesives: soluble in water, environmentally friendly, suitable for most operations;
(3) Hot-melt binder: prefabricated binder;
(4) UV hot melt adhesive: It is a new technology, which can be cured by UV lamp.

Most of the middle and high grade adhesive labels roll materials are made of latex and hot melt adhesive. For printing enterprises, it is not easy to choose among many products. Because different adhesives have different advantages and disadvantages, and correspond to different surfaces and environments, it is the common interests of printing enterprises and suppliers to find the most commonly used products. Because a widely used product is relatively easy to produce and has stable high quality, it also saves time and space for printing enterprises to store label materials for self-adhesive suppliers.
