What adhesive materials should be used for durability labels?
Durability labels refer to labels that remain on objects for a long time without falling off. The surface adhesive material of the label requires good weather resistance and toughness, and the adhesive agent requires high bonding strength and durability. Thin film materials are usually the preferred choice for durability labels
1. PET Adhesive Material
The commonly used thicknesses are 25um and 50um, and the colors include bright white, matte white, transparent, and metalized bright silver, bright gold, matte gold, and matte silver
The characteristics of PET adhesive material are as follows
a. The material has high hardness, tensile strength, and tear resistance
b. Excellent high temperature resistance, capable of withstanding temperatures up to 150 ℃
c. Excellent durability
d. Excellent transparency, opacity, and good metallization properties
e. Good chemical corrosion resistance, suitable for outdoor use, and widely applicable
2. PVC Adhesive Material
It is softer and more stretchable than PET material, with a thickness generally above 80um and 100um. The commonly used colors are white and transparent
The characteristics of PVC adhesive material are as follows
a. Good weather resistance, suitable for outdoor use
b. The application temperature range is between 20~80 ℃, and it is not resistant to high temperatures
c. Very good durability and chemical corrosion resistance
d. Due to its good flexibility, it is suitable for application on various types of surfaces
3. Synthetic paper adhesive material
It is a new type of synthetic material with the common characteristics of film and paper, with a thickness of over 60um and generally only white
The characteristics of synthetic paper adhesive materials are as follows
a. Has excellent tensile and shear strength
b. It has printing adaptability similar to paper and is suitable for printing with various inks
c· Good durability and corrosion resistance, suitable for outdoor use
d. Widely applicable and can replace various metal signs
PVC stickers, self-adhesive stickers
PVC adhesive stickers, also known as synthetic paper, have good chemical corrosion resistance and tear resistance, but their temperature resistance and tensile strength are generally affected by temperature; Widely used in applications such as electronics, machinery, batteries, outdoor stickers, etc. Due to the addition of many toxic additives during the production process of PVC labels, which are non recyclable and have poor biodegradability, they have a negative impact on environmental protection. So currently, the application of this label paper in the market is not as good as PET label paper.
PVC safety warning sticker
PVC safety warning stickers have low strength, average temperature resistance, poor tear resistance, and good transparency. But it has good flexibility, shrinkage, and opacity, good processing and labeling characteristics, can be used outdoors for a long time, and has excellent chemical corrosion resistance. Can be processed into various colors and glossy, matte, and metalized thin films. Generally, no surface treatment is required, suitable for various types of printing, especially for screen printing.
The fabric has important product labels such as transparent, glossy milky white, and matte milky white, which are resistant to water, oil, and chemicals. It is used for information labels of bathroom products, cosmetics, and electrical products, especially for high-tech resistant products;
PVC shrink film: suitable for battery trademark labels;
PVC adhesive material
PVC is the English abbreviation for vinyl. It is also a polymer material. The common colors for PVC label materials are sub white, pearl white, and transparent. The performance of polyvinyl chloride adhesive is similar to that of polyethylene adhesive labels. It has better flexibility and soft feel than polyethylene label paper. Commonly used in high-end occasions such as jewelry, watches, electronics, and metal. However, the degradation of polyvinyl chloride label materials is poor, which has a negative impact on environmental protection. Some developed countries abroad have begun to develop this alternative
PVC adhesive labels are composed of four parts: surface material, adhesive, backing paper, and printing ink. The common color tones include sub white, pearl white, and transparent. PVC adhesive labels have similar performance indicators to PET adhesive labels. They have better flexibility and a soft touch than PET adhesive labels, and are often used in high-end places such as jewelry, accessories, clocks, electronics, and metal materials. However, the solubility of PVC label materials is relatively poor, which has a negative impact on ecological environment protection. PVC adhesive labels are waterproof, moisture-proof, oil resistant, tear resistant, and heat-resistant, and are commonly used in manufacturing industries such as electronic devices, household appliances, automobiles, and chemical plants
PVC has non flammability, high strength, resistance to climate change, and excellent geometric stability. It has strong resistance to oxidants, reducing agents, and strong acids. In addition, due to its excellent flexibility, shrinkage, and opacity, as well as good processing and labeling performance, strong chemical corrosion resistance, and durability, it is suitable for long-term outdoor use

Can PVC adhesive material be paired with hot melt adhesive?
PVC adhesive material can be used in combination with hot melt adhesive
PVC (polyvinyl chloride) adhesive material has good stability and adhesion, while hot melt adhesive is a type of glue that is melted by heating and coated on the material to achieve adhesion
However, whether to choose to use hot melt adhesive combined with PVC adhesive material still needs to consider specific application scenarios and requirements. Here are some factors that may need to be considered:
Adhesive strength requirements:The adhesive strength of hot melt adhesive varies depending on the formula and process.. When choosing hot melt adhesive, it is necessary to ensure that its adhesive strength can meet the application requirements of PVC adhesive materials
Usage environment:Different usage environments have different performance requirements for hot melt adhesive and PVC adhesive materials.. For example, in high temperature or high humidity environments, it is necessary to choose hot melt adhesive and PVC adhesive materials that are resistant to high temperature and humidity
Process compatibility:The coating process of hot melt adhesive needs to be compatible with the processing technology of PVC adhesive material.. For example, if PVC adhesive materials need to be processed through printing, cutting, and other processes, it is necessary to ensure that the application of hot melt adhesive does not have adverse effects on these processes
Cost considerations: The cost of hot melt adhesive and PVC adhesive materials is also a factor to consider. When choosing a combination for use, it is necessary to comprehensively consider cost-effectiveness and practical application needs
