Jiangsu Hongkai Plastic Technology Co., Ltd., as a dedicated player in the core plastic manufacturing sector, has built a diverse and comprehensive product portfolio through years of industry experience and deep technical expertise. In the core tube field, we not only specialize in ABS core tube production but also actively expand our offerings, introducing the highly market-favored 3-inch 76mm ID PVC core tube.
Hongkai Plastic Technology meticulously select high-quality PVC (polyvinyl chloride) material as the core raw material for our 3-inch 76mm ID PVC core tube. PVC's unique molecular structure endows the core tubes with a range of outstanding physical and chemical properties. It offers excellent impact resistance, effectively cushioning external forces during handling, storage, and use—even in the event of accidental collisions—to prevent tube rupture or deformation, thereby safeguarding the integrity of the internally wound products. Additionally, PVC exhibits outstanding chemical corrosion resistance, withstanding erosion from various acids, alkalis, salts, and other chemicals. It maintains long-term stability in demanding environments like chemical processing and electronics manufacturing, as well as in humid conditions or areas with corrosive gases, without compromising product quality due to chemical degradation.
The 3-inch inner diameter design is a key highlight of this core tube. Extensive market research and practical application testing confirm this size achieves perfect compatibility with numerous common winding equipment and storage racks. During installation and removal, operators can easily complete core tube installation and replacement without complex adjustments or adaptations, significantly saving time and labor costs while markedly improving production efficiency. Moreover, its standardized dimensional design facilitates mass production and inventory management, further reducing operational costs for enterprises.
We pay meticulous attention to every product detail. The surface of the 3-inch PVC core tube undergoes special treatment, achieving a smooth, mirror-like finish. This smooth surface effectively minimizes friction with wound products, preventing issues like scratches and wear during winding and unwinding processes. This ensures the surface quality of the products remains unaffected. For products with extremely high surface integrity requirements, such as high-precision films and optical tapes, this core tube provides reliable protection, guaranteeing product integrity and premium quality.
3-inch 76mm ID PVC core tube, with their corrosion resistance, impact resistance, and dimensional stability, are widely used in the electronics and electrical industries for the winding and storage of films and tapes, ensuring a smooth product surface. In the automotive industry, they are used for winding interior materials and soundproofing materials; in packaging and printing, they are used for winding various papers and labels; they are also suitable for material winding scenarios in industries such as chemicals and textiles that require high pipe strength and environmental resistance. In these industries, many still insist on using paper tubes as core winding tubes, but PVC core tubes offer significant advantages: they have high compressive strength and chemical corrosion resistance, providing better protection for wound products; Smooth inner walls minimize fluid resistance and reduce surface damage to products; lightweight design facilitates handling and installation, lowering labor intensity and transportation costs; hygienic and eco-friendly with no secondary pollution; excellent dimensional stability prevents deformation, ensuring product precision; and strong customizability meets diverse requirements. Traditional paper cores fall short in these aspects.
PVC core tubes can be customized to different specifications, dimensions, and thicknesses according to customer requirements, meeting usage demands across various scenarios. Customization of traditional paper core tubes is relatively challenging, with limited options for specifications and sizes.
