Hot melt adhesive mainly has fast curing time, high bonding strength, environmental protection, and can also play a filling role. It is especially suitable for fully automatic production needs. Now is an era of rapid development, time is money, and every second is reduced. It is a profit, so hot melt adhesive is deeply loved by modern industry. Hot melt adhesive usually refers to the solid state at room temperature, heated and melted into a liquid state, coated, wetted the adherend, pressed and cooled, and the adhesive is bonded in a few seconds/minute. Solvent-based adhesive mainly organic solvent as the solvent adhesive, the main feature is high bonding strength, good water resistance, but volatile, pollution, and toxic. Therefore, with the promotion of environmental protection in recent years, people have become more aware of the dangers of solvent-based adhesives. The hot melt adhesive has the advantages of green environmental protection, low odor, low VOC, solvent-free, non-volatile, fast bonding speed, suitable for high-speed automatic operation, simple sizing process, convenient operation, the product itself is solid, easy storage, transportation, etc., so the application of hot melt adhesive is more and more extensive. Although the general printing enterprises know what kind of self-adhesive labels they need, they do not know how to choose the hot melt adhesive, which is very important for the pasting of self-adhesive labels. The following is to introduce some related contents of hot melt adhesive for labels, and provide the selection direction of hot melt adhesive for labels. In terms of the performance of the adhesive, the overall can be divided into two categories: permanent adhesive and removable adhesive. Permanent adhesive is generally used in electronic machinery, such as electronic standard, typical: mobile phone battery standard. Removable adhesives are generally used in food, personal care, etc., such as wet tissue labels, fruit labels, clothing labels, etc. Labeling the surface of an object, the processed label may be labeled on the surface of various materials, such as glass, metal, cardboard and plastic. The test shows that the bonding effect of hot melt adhesive on different pasting surfaces will be different. If you encounter a rough sticker surface you need to use high viscosity hot melt adhesive. In addition, it is necessary to pay attention to the cleanliness of the surface of the label. When any label is applied, it is necessary to keep the surface of the paste dry and free of oil and dust, so as to achieve the best labeling effect.
