What materials are generally recommended for waterproof labels

When choosing waterproof label materials, factors such as the label's usage environment, durability, printing effect, and cost need to be considered. Here are several commonly used waterproof label materials and their characteristics:

1. PET label paper

Features: PET label paper has excellent high temperature resistance, chemical corrosion resistance, good waterproof performance, durability, tensile strength, acid and alkali resistance, scratch resistance, friction resistance and other characteristics. Commonly seen are silver dragon and Asian silver label paper, with various colors such as bright white, matte white, silver, etc.

Application: Widely used in electrical, electric, mechanical equipment and other fields.

Attention: The cost of PET label paper is relatively high, but when combined with resin based carbon tape, the printing effect is better.

2. Synthetic paper (PP adhesive label paper)

Features: Matte white, tough material, good compression resistance, and good moisture and waterproof performance. The cost is lower than PET and it has thermal transfer printing performance.

Application: Widely used in electronic components, daily chemical products, and other applications.

Attention: It can be used in conjunction with mixed and resin based carbon tapes during printing.

3. PVC adhesive stickers

Features: Good chemical corrosion resistance, tear resistance, but average temperature resistance and tensile strength, affected by temperature.

Application: Widely used in electronics, machinery, batteries, outdoor stickers and other applications.

Attention: During the production process of PVC labels, many toxic additives are usually added, which are non recyclable, have poor biodegradability, and have a negative impact on environmental protection. Therefore, the current application of this label paper in the market is not as good as PET label paper.

4. A mixture of PP and PE (polyolefin)

Features: Unidirectional stretching treatment is carried out by machine, which has high tensile strength and tear resistance, low opacity, soft material, and compression resistance. The material can stretch in one direction to form a straight line, but it appears very hard in another direction. This type of material combines softness and stiffness, ensuring smooth labeling and good resistance to compression after labeling.

Application: Widely used in eyeglass care solutions and daily chemical products.

Attention: No special printing or environmental requirements.

5. Multi layer sticker synthetic paper (a type of PP material)

Features: It looks like paper, matte white, and has undergone biaxial stretching treatment. The material is tough and has good resistance to compression. At the same time, it has good thermal transfer printing performance and a hard material texture, suitable for flat or hard surfaces.

Application: It is widely used in electronic components and daily chemical products.

Attention: No special printing or environmental requirements.

6. Other special materials

Features: Special waterproof label materials that turn red or blue when exposed to water. These materials can undergo color changes in specific environments, serving as a warning or warranty reminder.

Application: Suitable for products that require special warnings or warranty reminders.

Attention: Choose suitable special materials according to specific needs.

Choose Suggestions

When choosing waterproof label materials, it is recommended to weigh them according to specific usage scenarios and requirements. Consider factors such as durability, waterproof performance, printing effect, and cost of the label, and choose the most suitable material. At the same time, you can also consult professional label suppliers or manufacturers for more professional advice and solutions.
