Can PVC adhesive labels be waterproof?
PVC adhesive labels have certain waterproof properties, but their effectiveness is affected by factors such as glue, printing process, and surface treatment. Waterproof coating or ink can enhance the waterproof effect, but it is not permanent and will weaken over time.
The usage environment and conditions also affect the waterproof performance.
Therefore, when choosing, it is necessary to evaluate the waterproof effect based on specific needs and the environment.
Is there any difference between PVC adhesive material and thermal paper adhesive material?
PVC adhesive material belongs to the category of film materials, with characteristics such as waterproofing, oil resistance, strong weather resistance, and high temperature resistance. Thermal paper belongs to the category of paper materials, including ordinary thermal paper, three proof thermal paper, and long-lasting thermal paper. Let's get to know each other together
1. PVC Adhesive Material
Widely applicable to label production in electronics, gift crafts, hardware, toys, plastic factories, machinery, food, and clothing. Specifications can be customized according to customer requirements, and printing forms are diverse: screen printing, color printing, offset printing, etc
Advantages: It has non flammability, high strength, resistance to climate change, and excellent geometric stability, and 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
Disadvantages: PVC has poor thermal stability and light resistance, and can begin to decompose and release hydrogen chloride (HCl) gas above 140 ℃, which is not conducive to environmental protection (alkaline stabilizers and HCl are often added in actual production to inhibit its catalytic cracking reaction). In addition, some toxic auxiliary materials such as plasticizer and anti-aging agent are added in the manufacturing process to enhance its heat resistance, toughness, ductility, etc., so its products generally do not store food and drugs. In addition, PVC label materials have poor biodegradability and have a negative impact on environmental protection
2. Thermal paper adhesive material
Thermal sensitive paper is a type of self-adhesive label paper. The surface paper of this label paper is treated with a high thermal sensitivity thermal sensitive coating, and there is a glue layer behind the paper for adhesion and fixation. The bottom layer is a base paper to protect the glue layer. After printing, the base paper can be torn off and used. The base paper is divided into ordinary blue base, white base, and imported Gracin base. Ordinary thermal paper is not waterproof, oil resistant, and tear resistant. Three proof thermal paper, waterproof, oil resistant, and friction resistant
Thermal adhesive stickers are suitable for various industries, such as supermarkets, restaurants, hotels, banks, telecommunications networks, medical institutions, and small and medium-sized fruit supermarkets. Considering that it does not need to be used in combination with carbon ribbons, it is both convenient and cost-effective
What are the suitable adhesive label materials for outdoor use?
If the label is located outdoors, continuous exposure to direct sunlight may be a challenge for label application, as ultraviolet radiation can cause the label to crack, peel off, and fade. Determine the label material to be used. The first thing to determine is the service life of the adhesive label. If the usage time is short, you can use lower priced self-adhesive materials such as paper. For anything that exceeds several months, we recommend using durable and weather resistant materials. Like PVC and PET materials, they can withstand freezing to high temperatures (-20 to 200 degrees) as well as other factors such as sunlight, chemicals, and wear and tear
1. PVC Adhesive Label Material
PVC adhesive labels are a type of polymer material that is non flammable, has high strength, is resistant to climate change, and has good geometric stability. PVC adhesive labels have strong antioxidant, reducing agent, and strong acid capabilities. Good flexibility, good shrinkage and opacity, good label processing, strong chemical resistance, durability, suitable for long-term outdoor use. It is widely used in the production of special materials such as trademarks, labels, clothing, curtains, holographic anti-counterfeiting, etc
2. PET Adhesive Label Material
PET is actually a polymer material, also known as polyester film. PET adhesive is waterproof, oil resistant, and not easily torn. Suitable for outdoor labels, it can resist corrosion from chemicals such as acid and alkali in harsh environments. Widely used as labels for high-performance products, such as toiletries, cosmetics, jewelry, and various motor products. Has good weather resistance, scratch resistance, high temperature resistance, and natural degradation performance. Therefore, it has become the preferred choice for many manufacturers
What is the difference between PVC and adhesive?
PVC and adhesive are two completely different materials, with different uses and characteristics. PVC is a plastic material mainly used for making various labels, posters, and stickers, while non drying glue is a type of adhesive mainly used to make various materials sticky.
If you are looking for a material to make labels, posters, or stickers, PVC and stickers are both great choices. You can choose which material to use based on your specific needs. For example, if you need a waterproof and durable material to make labels or posters, PVC may be a better choice. And if you need a material that can easily stick to various surfaces, then stickers may be more suitable for your needs.
PVC premium label paper
PVC is the English abbreviation for vinyl, which is also a polymer material. Common colors include sub white and pearl white. PVC has similar properties to PET, with better flexibility and a soft touch. It is often used in high-end occasions such as jewelry, watches, electronics, and metal industries. However, PVC has poor biodegradability and has a negative impact on environmental protection. Some developed countries abroad have begun to develop alternative products in this area.
