The selection and application of adhesive materials are crucial for ensuring the adhesion, durability, and visual effect of labels. Adhesive materials are mainly composed of three parts: surface material, pressure-sensitive adhesive, and substrate.
In terms of surface materials, paper materials such as copperplate paper and mirror copperplate paper are suitable for color printing and are commonly used in industries such as pharmaceuticals and food; PE film, PP film, PET film and other film materials have characteristics such as water resistance and oil resistance, and are widely used in daily chemical products and electronic products. The selection of pressure-sensitive adhesive should consider factors such as the surface condition of the object being applied and the labeling environment. Solvent based adhesives are economical but toxic, while emulsion based and hot melt adhesives are more environmentally friendly.
In specific applications, if high gloss labels are required, PET stickers can be chosen; If you need soft and strong adhesive labels, PVC stickers are a good choice. In addition, fragile paper stickers are commonly used for anti-counterfeiting sealing, while thermal paper stickers are suitable for price marking, etc.
In short, when choosing adhesive materials, it is necessary to comprehensively consider the characteristics, cost, environmental friendliness, and required performance of the materials to ensure the best performance of the labels in different application scenarios.
