PE self-adhesive is a label material based on polyethylene (PE) film, which stands out in terms of performance and effectiveness due to its unique material properties. Its surface is smooth and flexible, featuring excellent water resistance, moisture resistance and chemical corrosion resistance. It can resist the erosion of weak acids, weak alkalis and common solvents, and is scratch-resistant and tear-resistant. It can adapt to damp and slightly frictional environments. In terms of printing adaptability, it supports flexographic printing, screen printing and other processes. The ink has good adhesion, and the pattern colors are long-lasting. At the same time, it can be treated with matte or glossy finish according to requirements to meet different visual effects. In terms of bonding performance, when combined with water-based glue, oil-based glue and other types of adhesives, it can be firmly adhered to the surfaces of paper, plastic, metal, etc. The initial adhesive force and holding force are stable. Some products have a removable feature, and it is not easy to leave any residue after tearing. It is mainly used in scenarios such as packaging of daily chemical products (such as shampoo and body wash labels), food and beverage bottle stickers (waterproof and oil-proof), lubricating oil bucket labels, and simple outdoor labels. It can not only clearly display information but also, due to the flexibility of PE material, is suitable for pasting on curved objects. It is a practical label material that combines waterproofing and economy.
