Custom Self Adhesive High Temperature Resistant PVC Materials Manufacturers

How to balance the flexibility (easy labeling) and shrinkage resistance (preventing deformation) of high temperature resistant PVC label self-adhesive material?

In the field of industrial label materials, high temperature resistant PVC label self-adhesive material is favored for its unique performance advantages. This type of material must not only meet the flexibility required for daily labeling, but also maintain dimensional stability in high temperature environments, which places extremely high demands on material formulation and process. As one of the earliest domestic companies focusing on the research and development and production of self-adhesive materials, Shanghai Baozhongbao Adhesive Products Co., Ltd. has been committed to solving key technical problems in the application of such materials. Its high temperature resistant PVC label products have been widely used in high temperature environments such as electric vehicles and home appliances.

To achieve a perfect balance between flexibility and shrinkage resistance, we first need to start with the material formulation. Ordinary PVC materials are prone to deformation and shrinkage at high temperatures, which is mainly due to the rearrangement of molecular chains under heat. To this end, material engineers have developed special modified formulas to improve the performance of materials by adding specific proportions of heat stabilizers and plasticizers. Thermal stabilizers can effectively inhibit the degradation of PVC molecular chains at high temperatures, while carefully selected plasticizers can maintain good flexibility without reducing the temperature resistance of the material. Our R&D investment in this area has achieved remarkable results. Its high-temperature resistant PVC labels can be used for a long time in a high temperature environment of 120℃ to 150℃ without obvious deformation while maintaining excellent labeling performance.

The control of the production process is also crucial. In the film preparation process, the precise control of parameters such as temperature and pressure directly affects the final performance of the material. The use of advanced calendering technology can make the PVC molecular chain obtain an ideal orientation arrangement, which not only ensures the softness of the material at room temperature, but also improves its dimensional stability at high temperature. The later heat treatment process is also indispensable. Through a specific heat setting process, the internal stress of the material can be released in advance, thereby significantly reducing its shrinkage rate during subsequent use. Baozhongbao Adhesive Products has a complete production management system, and each process is strictly controlled to ensure the stability and reliability of product performance.

In actual application scenarios, different industries have different requirements for material performance. Take the battery vehicle body label as an example. This type of label not only needs to adapt to the labeling needs of complex curved surfaces, but also needs to withstand the test of long-term sun and rain. This requires that the material must be flexible enough to ensure the adhesion effect, and have excellent shrinkage resistance to ensure long-term stability. Through special surface treatment and adhesive formula optimization, modern high temperature resistant PVC label self-adhesive material has been able to perfectly meet these stringent requirements. The home appliance field pays more attention to the performance of labels in a closed high temperature environment, especially in application scenarios such as ovens and microwave ovens. The label material must ensure that no harmful substances are released at high temperatures, while keeping the logo clear and readable.

The choice of adhesive is also a key factor in balancing material performance. High-quality high temperature resistant adhesives must not only have good initial viscosity, but also maintain stable bonding strength under high temperature environments. Although the common acrylic adhesives on the market are low in cost, their performance in extreme high temperature environments is often unsatisfactory. In contrast, although silicone adhesives are more expensive, their excellent temperature resistance makes them the first choice for high temperature applications. The research and development team of Baozhongbao Adhesive Products has developed an adhesive system with independent intellectual property rights through continuous formula optimization, which greatly improves the temperature resistance level of the product while ensuring cost advantages.

With the increasingly stringent environmental regulations, the sustainable development of high temperature resistant PVC label self-adhesive material has also become a focus of industry attention. Traditional PVC materials may face environmental challenges during production and use, which has prompted material suppliers to continuously explore more environmentally friendly alternatives. The application of new materials such as bio-based plasticizers and halogen-free flame retardants enables high temperature resistant PVC labels to maintain excellent performance while meeting increasingly stringent environmental protection requirements. We study degradable label materials: launch fully degradable label materials for the fast-moving consumer goods industry to help customers achieve environmental protection goals throughout the entire life cycle of packaging.
