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 covered with a release paper (base paper). PVC film is processed from polyvinyl chloride resin and has the flexibility and chemical stability of plastic. Combined with the convenient sticking feature of self-adhesive, they are widely used in label scenarios that require weather resistance and durability.
Core characteristics of PVC self-adhesive labels
1. Excellent physical properties and high durability
Weather resistance is outstanding:
Waterproof and moisture-proof: The PVC film is a completely waterproof polymer material. Even when exposed to water or high humidity environments (such as bathrooms, kitchens, and outdoors), it will not absorb water and deform or wrinkle, making it suitable for labels on water cups, bathroom products, and outdoor equipment.
Wide temperature range: It can be used stably in the range of -10°C to 60°C (some modified PVC can withstand over 80°C), and it is not prone to cracking or softening under high or low temperatures for a short period, suitable for refrigerated food labels and internal labels of electronic devices, etc.
Anti-aging and corrosion resistance: It has certain resistance to direct sunlight and common chemical reagents (such as alcohol, detergents), and does not fade or become brittle over a long period, ensuring a more durable label pattern and text.
Good flexibility and adhesion:
The PVC film is soft and has strong extensibility, which can adapt to curved surfaces (such as plastic bottles, cosmetic tubes), concave and convex surfaces (such as tool handles), or irregular surfaces. After sticking, it is not likely to rising or falling off； at the same time， its tear resistance is better than that of paper-based substrates， and it is not easily damaged by daily friction or slight collisions.
2. Strong printing adaptability and diverse appearance
Flexible surface treatment： The PVC film can be made transparent， semi-transparent or colored (such as white， gold， or silver)， and the surface can be treated with matte， high gloss or frosted finish to meet different visual needs (such as transparent PVC is suitable for labels on light-colored bottles， with excellent concealment effect； colored PVC can enhance the label's recognition).
Compatible printing processes： It is compatible with offset printing， screen printing， and digital printing， with strong ink adhesion， capable of achieving fine patterns and gradient color printing， and supporting secondary processing such as hot stamping， laser， and local UV， enhancing the label's texture and anti-counterfeiting ability.
3. Controversy over cost and environmental performance
Moderate cost： The production process of PVC film is mature， and the raw material cost is lower than that of high-end plastic substrates such as PET and PP. The overall price is moderate， suitable for scenarios requiring durability but with limited budgets (such as industrial labels and daily-use labels).
Environmental performance is controversial：
Common PVC may contain plasticizers (such as phthalates) and stabilizers (such as lead salts) during production. If used in food contact scenarios (such as directly adhering to food surfaces)， there may be safety concerns (select food-grade PVC is necessary)；
In addition， PVC is difficult to degrade naturally after disposal， and burning may release toxic gases (such as hydrogen chloride). Its environmental performance is not as good as paper or degradable plastic substrates. Some countries and regions have restricted its use in food， children's products， and other fields.
4. Attention to limitations
Limited heat resistance： Although it is better than paper， it may deform or the adhesive may fail in an environment above 60°C (such as high-temperature sterilization cabinets， near engines)；
It is prone to hardening at low temperatures： When the temperature is below -10°C， the PVC film will gradually lose flexibility and may crack or peel off from the surface of the adhered object；
The transparency is slightly inferior to PET： The light transmittance of transparent PVC is usually between 80% and 85%， lower than that of PET's over 90%， making it less suitable for "invisible label" scenarios (such as high-end glass bottles) with extremely high "invisible label" requirements.
