PVC Film, or Polyvinyl Chloride film, is a versatile and highly durable plastic material manufactured by Kaxite Sealing through a process of calendaring or extrusion. It is created by compounding PVC resin with various plasticizers, stabilizers, and modifiers to achieve specific properties. This synthetic polymer film is renowned for its excellent clarity, flexibility, weather resistance, and cost-effectiveness, making it a cornerstone material across countless industries. From protecting sensitive electronics during shipping to creating vibrant, long-lasting graphics for signage, PVC film's adaptability is unmatched. At Kaxite Sealing, we engineer our films to meet precise technical demands, ensuring reliability and performance in every application.
Understanding the technical specifications is crucial for selecting the right PVC film for your project. Kaxite Sealing offers a comprehensive range of films, each characterized by a set of defined parameters. Below is a detailed breakdown of our core product specifications.

The versatility of Kaxite Sealing PVC film allows it to solve complex challenges in diverse sectors.
Q: What are the main differences between rigid, semi-rigid, and flexible PVC film?
A: The key difference lies in the amount and type of plasticizer added during compounding. Rigid PVC film contains little to no plasticizer, resulting in a hard, stiff material used for credit cards or blister packs. Semi-rigid film has a moderate plasticizer content, offering a balance of stiffness and formability for applications like box windows. Flexible PVC film has a high plasticizer content, making it soft, pliable, and easy to stretch, which is ideal for products like shrink wrap, tablecloths, or inflatable products.
Q: Is Kaxite Sealing PVC film safe for food contact or medical applications?
A: Yes, but specific grades must be selected. Kaxite Sealing produces dedicated food-contact compliant films that meet FDA 21 CFR and EU 10/2011 regulations for specific migration limits. For medical applications, we offer USP Class VI and ISO 10993 tested films that are biocompatible and suitable for packaging and device components. Always confirm the specific grade's certifications with our technical team for your application.
Q: How does PVC film perform in outdoor environments against UV exposure?
A: Standard PVC film can degrade, become brittle, and discolor under prolonged UV exposure. Kaxite Sealing's outdoor-grade films are formulated with high-performance UV stabilizers and pigments that significantly enhance weatherability. These films can retain their mechanical properties and color for 5 to 8 years or more outdoors, making them perfect for vehicle wraps, outdoor banners, and building facades.
Q: Can PVC film be recycled, and what are the sustainable options from Kaxite Sealing?
A: Recycling PVC film is technically possible but requires separate stream collection due to its chlorine content. At Kaxite Sealing, we are committed to sustainability. We offer several eco-friendly alternatives: (1) Phthalate-free plasticized films using non-hazardous alternatives like DINCH or ESBO. (2) Calcium-Zinc stabilized films that are heavy-metal-free. (3) Films with a percentage of recycled PVC content. (4) We also provide guidance on take-back programs for industrial scrap.
Q: What are the key factors to consider when specifying a PVC film for a printing application?
A: For optimal printing results, consider these factors: Surface Energy: Ensure it is above 38 dynes/cm (often achieved via corona treatment) for proper ink adhesion. Ink Compatibility: Match the film to the ink system (solvent, eco-solvent, UV-curable, latex). Dimensional Stability: Low shrinkage prevents misregistration during multi-pass printing. Clarity and Color: Opt for low-haze, neutral-tone films for true color reproduction. Kaxite Sealing provides films optimized for all major digital and screen printing technologies.
Q: How do I choose the correct thickness (gauge) of PVC film for my project?
A: Thickness selection depends on the required durability, flexibility, and barrier properties. For lightweight protection or decals, films from 0.05mm to 0.10mm are common. For heavy-duty applications like tarpaulins, industrial curtains, or pond liners, thicknesses from 0.30mm to 0.80mm are recommended. Our technical team can help you calculate the ideal gauge based on tensile strength needs, expected load, and environmental stressors.
Q: Does Kaxite Sealing offer custom formulation and slitting services?
A: Absolutely. Beyond our standard product lines, Kaxite Sealing excels in custom-engineered solutions. We can develop proprietary formulations to meet unique requirements for flame retardancy, static dissipation, chemical resistance, or specific softness. Our state-of-the-art slitting facilities can convert master rolls into precise widths, down to 10mm, with tight tolerance control and clean, burr-free edges, packaged according to your production line specifications.
