There are many kinds of materials for self-adhesive label paper. According to different application scenarios and needs, it is mainly divided into two categories: paper and film. The following are common materials and their characteristics:

1. Paper material
Offset paper: mostly used for information labels and barcode printing, suitable for high-speed laser printing and inkjet printing, and often used for handwritten price labels such as supermarkets and tea.
Coated paper: The surface is smooth and delicate, and the printing color is smooth. It is often used for labels such as medicines, food, wine, electrical appliances, and cultural supplies. The disadvantage is that it is poor in waterproof and oil resistance, but it can be improved after film.
Mirror coated paper: high gloss, suitable for high-end product labels such as medicines, food, edible oil, wine, beverages, and electrical appliances.
Kraft paper: with color, suitable for retro style design, often used for labels such as red wine, cultural supplies, and ethnic style.
Aluminum foil paper: good moisture and oil resistance, suitable for labels such as food, daily chemicals, and cosmetics.
Fragile paper: used for anti-counterfeiting labels, which will break once torn, and is commonly used in electrical appliances, medicines, etc.
Thermal paper: sensitive to temperature, displays information after heating, and is commonly used in supermarket commodity price labels.
2. Film materials
PE (polyethylene film): good flexibility, suitable for pasting on curved surfaces, excellent waterproof and moisture-proof performance, commonly used in bathroom supplies, cosmetics, etc.
PP (polypropylene film): high transparency, chemical corrosion resistance, suitable for labels of cosmetics, beverages, foods, etc.
PET (polyester film): high temperature and chemical corrosion resistance, suitable for outdoor use and high-quality labels, commonly used in electronic products, medical supplies, etc.
PVC (polyvinyl chloride film): soft and easy to shape, good light transmittance, commonly used in electronic products, medical supplies, etc.
OPP (oriented oriented polypropylene): excellent moisture resistance and mechanical properties, commonly used in labels of cosmetics, beverages, foods, etc.
3. Other special materials
Synthetic paper: Environmentally friendly and durable, it has both the printing applicability of paper and the waterproof performance of plastic, and is suitable for high-end product packaging.
Rainbow film: It has a unique rainbow color effect, is waterproof and oil-proof, meets environmental standards, and is suitable for labels with special visual effects.
Summary
The material selection of self-adhesive label paper should be determined according to the specific application scenario, environmental requirements (such as waterproof, high temperature resistance, etc.) and visual effect requirements. For example, PE film is suitable for scenarios with high flexibility requirements, while PET film is more suitable for environments with high temperature resistance and chemical corrosion resistance.
