material (2) viscose (3) the end of paper.Will be able to help us consider the following issues
Apply the correct choice of materials.
1. Viscose and the removal of permanent nature can be divided into
Performance to the performance of viscose, viscose generally can be divided into two categories : permanent and remove sexual viscose.
2. Surface emphasized the significance of labels
Adhesive labels may be used as adhesive materials processing in the surface of various materials, such as glass, metal,cardboard and plastic.And PVC plastics can be further classified into : high-density polyethylene, low density polyethylene, polypropylene.Testing showed that the labels face the greatest impact on the performance of viscose.
3. Labels the surface of the substrate structure
Intuitively that rough surface on the labels need strong viscose viscosity.
4. The surface of the substrate labels
Labels the substrate surface and curved parts, a curvature of the surface if the labels (for example,surface of the bottle is less than 3 cm in diameter) may be required viscosity and soft tissues have a good strong viscose.
5. Label surface cleanliness
Adhesive materials suitable for surface cleaning, drying, non-oil and non-dust labels substrate.
6. Plasticizer on the adverse effects of viscose
PVC plasticizers can be seen frequently in the adhesive, after a certain period of time will reduce the viscosity viscose.
7. Labeling the use of environmental conditions
Stickers conditions - Label need cold, hot, humid conditions adhesive or adhesive under greenhouse conditions.Use of the environment - is not exposed to the freezing point following Label the environment, for outdoor, high temperature,Chao containing wetlands or ultraviolet light, and the possibility of exposure to chemicals such as solvents.
Please note : Adhesive materials identified in the past, the same should be printed labels under the conditions of processing and testing.
