What is multi-layer adhesive label?
Multi layer adhesive labels are a special type of adhesive label characterized by containing multiple layers of base paper or surface material. This type of label can be divided into multi-layer base paper adhesive labels and multi-layer surface material adhesive labels. In the past, the application scope of multi-layer adhesive labels was not extensive, mainly used for printing anti-counterfeiting labels and product descriptions. However, with the increasing demand from end product users for exquisite product labels and anti-counterfeiting labels, as well as the growing demand for special applications of product labels, the application of multi-layer adhesive labels has become increasingly widespread in recent years.
Multi layer adhesive labels are widely used in business fields such as cosmetics, pharmaceuticals, and food. In the cosmetics industry, multi-layer folded adhesive labels with text and images on both sides are mainly used. These labels are pasted on transparent bottle bodies and have good decorative effects. In addition, some lubricant bottles may also have multiple layers of folded adhesive labels attached to them. In pharmaceutical and food enterprises, the use of multi-layer folded adhesive labels mainly involves printing graphics and text on the surface material, and printing product instructions on the following surface materials. In this way, users can open the multi-layer folding user manual below after removing the layer material, refer to relevant information, and then close the layer material again after reading. The appearance design of the product label remains unchanged. Compared with ordinary instructions, this product label not only has a lower cost, but also has obvious advantages in packaging anti-counterfeiting labeling due to the use of specialized printing machinery and equipment, which has the characteristics of special process and high processing difficulty.
With the development of the market and the improvement of consumer awareness, multi-layer product labels will become a new trend, and the requirements for printing technology will also be further increased.
Can self-adhesive labels be waterproof?
Many people want to know if ordinary adhesive stickers have waterproof properties, and if so, what is the waterproof effect? In fact, there is a type of waterproof adhesive sticker on the market. Below, I will compare it with ordinary daily chemical adhesive stickers using waterproof adhesive stickers
1. Waterproof Adhesive Stickers
Ordinary thin film adhesive stickers are waterproof adhesive stickers. Common waterproof adhesive sticker materials include PP synthetic paper adhesive stickers, milky white PE adhesive stickers, transparent film adhesive stickers and stickers, PET adhesive stickers, and so on, all of which can be waterproof and moisture-proof
So next, let's take copperplate paper stickers as an example for adhesive sticker printing factories: for example, pour some water on a cardboard box and wait for more than ten minutes. Most of the water is basically dry, and the handwriting on the coated paper adhesive stickers is just like at the beginning. Adhesive printing factories will use good water-based adhesives, so the stability of the stickers will be even higher. Not only can they be waterproof and moisture-proof, but there is no need to worry about the stickers falling off
In fact, there are many materials for waterproof and moisture-proof adhesive stickers. Printing companies can select sticker materials that are more suitable based on the material of the adhesive surface layer, the indoor environment in which the stickers are applied, the actual effect that the sticker design needs to achieve, and whether there are special process technologies involved

What are the characteristics of synthetic paper stickers?
Adhesive labels are still quite common in our daily lives, with a wide variety of types. The characteristics and application fields of different types of adhesive labels are different. Therefore, we need to have a better understanding of the characteristics of the adhesive labels we need to use. Synthetic paper adhesive labels are one of them. Today, Xiao Zhang will take you to learn about the characteristics of synthetic paper stickers
Synthetic paper adhesive, also known as Synthetic paper in English, is a new type of plastic material product and an environmentally friendly adhesive. It has the characteristics of light weight, high strength, tear resistance, good printability, light shielding, UV resistance, durability, and economic and environmental protection
1. Environmental Protection: The raw material source and production process of polypropylene synthetic paper will not cause environmental damage. The product can be recycled and reused, and even if it is incinerated, it will not produce toxic gases and cause secondary pollution, which meets the requirements of modern environmental protection
2. Compared to regular paper, synthetic paper has superior performance: it has the characteristics of high strength, tear resistance, perforation resistance, wear resistance, folding resistance, moisture resistance, and insect resistance
3. More versatile than regular paper: Synthetic paper has excellent water resistance, making it particularly suitable for outdoor advertising and non paper trademark labels. Due to the dust-free and lint free nature of synthetic paper, it can be used in clean rooms
4. Can come into direct contact with food
5. Superior processing performance: Synthetic paper has the characteristics of high strength, tear resistance, perforation resistance, wear resistance, folding resistance, moisture resistance, and insect resistance
6. PP pearl synthetic paper is waterproof, durable, tear resistant, and has good weather resistance. It is very suitable for use in scenic spots, mountain climbing, tourist route maps, and military maps

Does temperature have an impact on adhesive labels?
Some customers often report that the adhesive strength of self-adhesive labels is insufficient, resulting in the detachment of product labels. In the food industry, such issues are particularly prominent. On a common product label, the description of the ambient temperature is as follows: maintain room temperature, applicable ambient temperature range is -50 ° C to 80 ° C, and the minimum ambient temperature on the product label is 7 ° C. There are three types of environmental temperatures mentioned here, namely storage environment temperature, labeling environment temperature, and application environment temperature. Next, we will explore the significant impact of environmental temperature on product labeling
Adhesive labels are affected by surrounding moisture, coupled with temperature changes in the morning and evening, and repeated use can cause label deformation. However, professional low-temperature resistant adhesive labels can withstand extreme environmental temperatures and temperature changes, and are suitable for all refrigerated storage products
Refrigerated food labels can have a significant impact on the quality of adhesive labels during cold and humid weather. What are the consequences of using adhesive labels in an environment with temperatures below minus tens of degrees? What kind of product labels should we choose
The characteristics of a cold storage environment are high humidity and low temperature. If ordinary product labels are used in cold storage, the labels are prone to deformation, wrinkling, and detachment. In addition, there are various forms of packaging for items inside the cold storage. Therefore, the selected product labels should have excellent waterproof, moisture-proof, and low-temperature resistance performance
There are various types of adhesive for product labels, and ultra-low temperature adhesive should be used in cold storage. If the label is attached at room temperature and then placed in the cold storage, the label paper should be made of a material with obvious elasticity. Considering that the packaging form of the item may be ordinary paper packaging or nylon bag packaging, different materials of product labels can be selected according to the needs
