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
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
