Why do thermal paper stickers fade?

The coating of thermal paper adhesive labels contains specific thermal sensitive components, such as no color dyes (such as crystal violet lactone in the triphenylalkylbenzene phthalein system, fluoranthene management system, etc.) and color developing agents (such as para hydroxybenzoic acid and its esters, salicylic acid, etc.).

When these components are heated, they undergo chemical reactions and produce colors.

However, this color reaction is reversible, meaning that colored products will decompose to varying degrees on their own, causing the color of the handwriting to gradually fade.

Can PET stickers be used as beer labels?

PET stickers can be used as beer labels.

PET adhesive has good hardness and brittleness, can withstand certain high temperatures, resist harsh environments, and resist corrosion from chemicals such as acid and alkali. At the same time, it also has characteristics such as waterproofing, oil resistance, resistance to tearing, and high temperature resistance, which make it particularly suitable for use as a beer label. This is because beer requires label materials that are waterproof, moisture-proof, and resistant to low temperatures during storage and transportation, and have strong adaptability and are not easily detached. In addition, PET adhesive label paper also has good natural biodegradability, which can meet environmental protection requirements, which is particularly important in the context of increasing environmental awareness. In addition, its excellent printing performance also makes it suitable for various printing equipment and can produce various exquisite labels.

Therefore, PET adhesive is a very suitable material for use as beer labels.

The advantages of synthetic paper adhesive labels compared to other labels are mainly reflected in the following aspects

1. Environmental friendliness: Synthetic paper does not require the use of wood or natural textile materials in the production process, greatly reducing the consumption of natural resources. At the same time, synthetic paper is recyclable and has a high reuse rate, which is in line with environmental protection concepts. In contrast, traditional paper labels generate a large amount of waste during the production process, causing pollution to the environment.

2. High strength and wear resistance: Synthetic paper has high strength and wear resistance, and can withstand various harsh environmental tests. In logistics, warehousing and other processes, synthetic paper adhesive labels can maintain clear and complete identification, and are not easily detached or damaged. Traditional paper labels are prone to wear and tear during transportation, which affects the clarity and integrity of the identification.

3. Lightweight and Soft: Synthetic paper adhesive labels use synthetic paper as the substrate, which has a lighter weight and softer texture compared to traditional paper. This makes synthetic paper adhesive labels more flexible when pasting and able to adapt to various curved surfaces.

5. Waterproof and moisture-proof: Synthetic paper adhesive labels have good waterproof and moisture-proof properties, and can maintain good adhesion and durability in humid environments. This makes synthetic paper adhesive labels widely applicable in situations where waterproofing and moisture resistance are required.

6. High temperature resistance: Synthetic paper adhesive labels can withstand high temperatures and are not easily deformed or foamed. This makes synthetic paper adhesive labels have good adaptability in situations where high temperature resistance is required.

In summary, synthetic paper adhesive labels have shown excellent performance in environmental protection, strength, wear resistance, lightweight and soft, waterproof and moisture-proof, and high temperature resistance. Therefore, they have been widely used in various fields such as cable labels, medical, pharmaceutical labels, electronic devices, household appliances, automobiles, chemical industries, and more.
