Is synthetic paper adhesive resistant to high temperatures?
Synthetic paper adhesive has good high temperature resistance.
Synthetic paper adhesive is a new type of plastic material product, and its temperature resistance range mainly depends on the composition and thickness of the material. Generally speaking, the temperature resistance range of synthetic paper is between -70 ℃ and 230 ℃. This range enables synthetic paper adhesive labels to maintain their stability and clarity in high temperature environments, thus it has been applied in some high-temperature processing and production processes.
In addition, synthetic paper stickers also have various other excellent characteristics, such as light weight, high strength, tear resistance, perforation resistance, wear resistance, folding resistance, moisture resistance, insect resistance, etc. These characteristics have made synthetic paper stickers widely used in fields such as food packaging and pharmaceutical packaging.
In summary, synthetic paper stickers do have good high-temperature resistance and can meet most application needs. When using synthetic paper in high-temperature environments, it is important to avoid contact with metals, keep it dry, avoid excessive stretching, and take protective measures.
Is the UV color changing label reversible?
There are two situations regarding whether the color change of ultraviolet color changing labels is reversible:
Irreversible color change: Many UV color changing labels use coating materials with irreversible color changes.. After this material undergoes a color change under ultraviolet irradiation, even if the ultraviolet disappears, the color cannot be restored to its original state. This type of label is typically used in scenarios that require one-time confirmation of UV exposure, such as UV labels for UV management
Reversible discoloration: Although irreversible discoloration is more common, some UV color changing labels also use reversible discoloration materials. These materials undergo color changes under UV irradiation, and when the UV disappears, the color can be restored. This reversible change is usually based on the principle of photochromism, but it should be noted that not all ultraviolet color changing labels have this characteristic
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.
How to choose materials for daily chemical labels?
The so-called daily chemical label refers to the label used for shampoo, shower gel, facial cleanser, laundry detergent, and toilet cleaner. At present, the labels for daily chemical products in the market are mainly made of PE or PP adhesive materials, so using the same material for thin film adhesive labels is the most suitable: on the one hand, thin film materials are not easily affected by humidity; On the other hand, the film label made of the same material as the packaging bottle has a shrinkage rate that is basically the same as that of the packaging bottle, so it is least likely to have warping problems
But if used as a toilet liquid label, as it belongs to a relatively low-end daily chemical product, using thin film adhesive label material will increase the product cost to a certain extent. Therefore, it is recommended that those who usually use copperplate paper to process such labels for cost considerations, but need to film or polish the labels to reduce the impact of external humidity changes on the label material. Let's briefly discuss the characteristics of these three materials:
1. PE Adhesive Material
PE adhesive is a type of polyethylene film, commonly available in three colors: white, transparent, and bright silver; It has the characteristics of soft material, good bi-directional ductility, resistance to compression, waterproofing, and moisture resistance. Therefore, PE material is preferred for extruded daily chemical products
2. BOPP Adhesive Material
BOPP material is a type of polypropylene film, commonly divided into synthetic paper, pearl film, transparent BOPP, shiny silver BOPP, laser BOPP, etc. It has the characteristics of soft material, smooth and transparent surface, high transparency, temperature resistance, and moisture resistance. Non extruded daily chemical labels can be made of BOPP
3. Copperplate paper adhesive material
Copperplate paper material is a common economical material on the market, which is often chosen for cost saving bottle body daily chemical products. The material itself is not waterproof and has poor moisture resistance, so it is generally used after lamination
Okay, now you know how to choose
