What is the difference between coated paper adhesive and PET adhesive?

Coated paper self-adhesive and PET self-adhesive in many aspects there are significant differences, these differences are mainly reflected in the material, performance, application scenarios and cost.

First, the material difference

Coated paper self-adhesive: Coated paper self-adhesive is a self-adhesive produced with coated paper as the backing paper. Coated paper is a common printing paper, with high printability, smooth and delicate surface, suitable for various printing methods. The self-adhesive label is mainly composed of coated paper and coating (adhesive), and the coating can adhere to a variety of surfaces.

PET adhesive: PET adhesive is a self-adhesive label produced with PET (polyethylene terephthalate) film as the base material. PET is a high-strength, high-transparency plastic material with good corrosion resistance, wear resistance and water resistance.

Second, performance differences

Coated paper adhesive:

Advantages: smooth printing color, strong color printing reduction, to meet the high requirements of print quality; Widely used, suitable for all walks of life.

Disadvantages: not waterproof, not oil proof, easy to tear. However, it can be enhanced by coating treatment to enhance its waterproof and oil-proof performance, and it is not easy to tear.

PET adhesive:

Advantages: high transparency, good resistance to water, oil and chemicals; Strong mechanical properties, suitable for long-term use under various environmental conditions.

Disadvantages: Compared with coated paper adhesive, its cost may be slightly higher.

3. Application scenarios

Coated paper adhesive: Because of its good printing effect and low cost, it is widely used in the production of information labels for drugs, food, cooking oil, wine, beverages, electrical appliances, cultural supplies and so on. It is especially suitable for one-time use or frequent replacement occasions, such as food packaging, price labels, etc.

PET adhesive: Due to its excellent heat resistance, weather resistance and chemical stability, PET adhesive labels are commonly found in high-end fields such as electronic products, medical packaging, cosmetics and so on. These areas have high requirements for the durability and texture of the label.

Fourth, cost consideration

In general, the cost of coated paper self-adhesive labels is relatively low, suitable for large-scale production and wide application. The cost of PET sticker may be relatively high due to its superiority in material and performance, but in specific application scenarios, its high added value and long-term durability make this cost reasonable.

In summary, coated paper self-adhesive and PET self-adhesive have significant differences in material, performance, application scenarios and cost. When selecting a self-adhesive label, comprehensive consideration and selection should be made according to the specific needs and scenarios.
