1.Permanent and removable options

In terms of the performance of adhesives, they can be divided into two categories: permanent adhesives and removable adhesives.(Permanent is generally used in electronic machinery, such as electronic label, typical: mobile phone battery label, removable is generally used in food, personal care, such as: wet wipes label, fruit label, clothing label, etc.)

2.The surface of the attached object

Because labels processed with self-adhesive materials may be labeled on the surface of various materials, such as glass metal cardboard and plastic, and plastic can be further divided into POLYvinyl chloride high density polyethylene.Tests show that different labeling surfaces have the greatest impact on performance (it is best to use glue and materials with the same or similar chemical composition to paste the material).

3.Label the surface structure of the substrate

Intuitively speaking, a rough labeling surface requires a strong glue

4.Label the surface shape of the substrate

The surface of the base material can be flat or curved. If the surface of the base material has a certain radian (for example, the surface of a medicine bottle with a diameter of less than 3cm), the paper with good adhesion or a strong glue may be required.It is also necessary to choose materials with better flexibility and tensile resistance, such as PVC and flat surface of the pasted material, which can adapt to a wider range of labeling materials.

5.Cleaning condition of label surface

Self-adhesive material is most suitable for clean, dry, oil-free and dust-free labeling base material (any labeling, it is necessary to keep the surface of the paste dry, oil-free and dust-free, so as to achieve the best labeling effect)

6.Adverse effect of plastic on glue

Adhesive viscosity needs to be pasted under cold, hot, humid or room temperature conditions.Use the environmental sticker label whether it is exposed to the environment below freezing point, whether it is used outdoors under high temperature, humidity or ultraviolet light, and whether it is close to a high temperature car engine.
