PVC self-adhesive labels are a type of self-adhesive label material made from PVC film as the base material. The backside is coated with pressure-sensitive adhesive (adhesive) and is attached with a release paper (base paper). The base material PVC is a common plastic polymer. By adding additives such as plasticizers and stabilizers, it forms films of different hardness (soft / hard). Combined with the characteristics of the pressure-sensitive adhesive, it can be easily adhered to various surfaces and are widely used in identification, decoration, and information marking scenarios.
Core characteristics of PVC self-adhesive labels
1. Excellent physical properties and high durability
Weather resistance: It has good resistance to ultraviolet rays, high and low temperatures (generally can withstand -10°C to 60°C, special formulations can expand the range), and moisture resistance. It is not prone to fading, cracking or deformation due to sunlight exposure, rain washing or temperature changes, making it suitable for outdoor or humid environments (such as bathroom product labels, outdoor equipment identification).
Tear resistance and abrasion resistance: The PVC film itself has high toughness, with better tensile and tear resistance than ordinary paper self-adhesive labels. The surface is smooth and wear-resistant, and even with frequent contact or slight scratching, the label pattern and text are not easily worn off, suitable for toys, tools and other products that need long-term use.
Chemical resistance is good: It has certain resistance to oils, weak acids and weak bases, and is not easily dissolved or deformed after being soaked by liquids, suitable for scenarios where chemical substances may come into contact (such as cosmetics, detergents, small appliances).
2. Diverse appearance and strong decoration ability
Transparency and rich colors: The base material can be transparent, semi-transparent, matte or colored (such as white, yellow, red, etc.). Transparent PVC self-adhesive labels can blend with the surface of the object being attached, while colored ones can enhance the identification of the sign through bright colors; some products can also be treated with matte or glossy surfaces, meeting different style requirements.
High printing adaptability: The surface is smooth and flat, suitable for various printing processes (such as screen printing, digital printing, offset printing, etc.), with bright and clear printed patterns, clear details, and strong ink adhesion, not prone to color fading. In addition, it can undergo secondary processing such as hot stamping, laminating, and die-cutting to achieve three-dimensional and anti-counterfeiting effects.
3. Excellent flexibility and adhesion
Soft and moldable: Soft PVC self-adhesive labels have good flexibility and can adhere to curved surfaces, arcs (such as plastic bottles, pipes, arc-shaped packaging boxes), without warping or falling off; hard PVC is more rigid and suitable for flat or slightly curved surfaces, maintaining the flatness of the label.
Wide adhesive range: The pressure-sensitive adhesive layer can be selected as general adhesive, strong adhesive or removable adhesive, and can firmly adhere to various material surfaces such as plastic, glass, metal, ceramic, etc., even on slightly rough surfaces (such as some plastic shells) it can maintain stable adhesion.
4. Cost and environmental characteristics
High cost-effectiveness: The raw material cost of PVC is relatively low, and the production process is mature, so the cost of PVC self-adhesive labels is lower than that of PET, aluminum foil and other high-end materials, suitable for mass-produced mid-to-low-end product labels.
Environmental controversy: Traditional PVC contains plasticizers (such as phthalates), which may release harmful substances when exposed to high temperatures or long-term use, and when burned, it produces toxic gases such as hydrogen chloride. Its environmental performance is poor; currently, "environmentally friendly PVC" (without plasticizers or low-toxicity formulations) has been introduced, but the cost is high and the application range is limited.
5. Special functional expansion
Waterproof and moisture-proof: The PVC film itself does not absorb water, even if the adhesive layer comes into contact with a small amount of water, it is not prone to falling off or deforming, suitable for bathroom products, outdoor equipment, etc. humid scenarios.
Flame retardancy (some models): PVC self-adhesive labels with added flame retardants can have certain flame retardant effects, suitable for identification scenarios of electrical appliances, cables, etc. that require fire protection.
