1. The surface structure of the label substrate
Intuitively, a rough label surface requires a more viscous glue.
The surface shape of the label substrate
The surface of the label substrate is divided into flat and curved surfaces. If the surface of the label has a certain curvature (for example, the surface of a medicine bottle with a diameter of less than three centimeters), the tissue paper may be required to have good fit or glue with strong viscosity. It is also necessary to choose materials with better flexibility and stretch resistance, such as PVC. The flat surface of the object to be attached is more suitable for the labeling material.
2. The cleanliness of the label surface
Self-adhesive materials are most suitable for labeling substrates with clean, dry, oil- and dust-free surfaces. (For any labeling, it is necessary to keep the surface of the object dry, free of oil and dust, so as to achieve a better labeling effect)
3. The adverse effect of plasticization on glue
Labeling Condition - Self-adhesive viscosity needs to be pasted in cold, hot, humid or room temperature conditions.
Use environment - whether the self-adhesive label is exposed to the environment below freezing point, whether it is used outdoors, under high temperature, humidity or light containing ultraviolet rays, and whether it is close to the car engine with high temperature.
4. Choice of Sex and Removability
According to the performance of adhesives, they can be divided into two categories: adhesives and removable adhesives. (It is generally used in electronic machinery, such as electronic labels, typical: mobile phone battery labels, removability is generally used in food, personal care, etc., such as: wet tissue labels, fruit labels, labels on clothes, etc.)
5. The surface of the object to be attached
Because labels processed with self-adhesive materials may be labeled on the surface of various materials, such as glass, metal, cardboard and plastic. And plastics can be further divided into: polyvinyl chloride, high density polyethylene. Tests have shown that different decal surfaces have a greater impact on performance.
