A label material source factory should be responsible for consumers while meeting consumer requirements. Regardless of the development trend, the quality of labels lies in their basic parameters.
Three most common problems of labels are: warping, bubbling and wrinkling. The whole cycle of label production and use involves a number of links, which may be affected by any factors. For example, warping may be caused by too low viscosity of adhesive, insufficient pressure of the labeling machine or too large surface coating tension of labels.
Modified TPE label for household necessity
Substrate: TPE
Substrate thickness (um): 65±5%
Adhesive: Environmentally friendly adhesive
Total thickness (um): 83±5
Substrate: white Glassine backing paper
Initial adhesion (#): 6~10
Wear-resistant steel adhesion(kgf/inch): 8~14
Holding force (H): >18
High heat resistance: -20~90
So, what are the characteristics of daily chemical label materials?
1. High flexibility, suitable for sticking on curved or arced surfaces;
2. Fewer crystal points, smooth and flat surface, suitable for labeling of extruded plastic bottles;
3. High tensile strength, without deformation or tear;
4. Corona-treated surface, high surface energy, suitable for UV rotation, screen, flexography and other printing modes, with good ink adhesion;
5. Environmentally friendly adhesive, conforming to the national and local laws and regulations as well as industrial environmental protection certification standards.
