PVC film is a type of plastic film material made primarily from polyvinyl chloride (PVC) resin. It is produced by adding auxiliary materials such as plasticizers, stabilizers, lubricants, and fillers, then processed through mixing, plasticizing, calendering, or extrusion/blow molding. The core component, polyvinyl chloride, is a thermoplastic resin with excellent mechanical properties, chemical stability, and processability, which makes PVC film widely used in industries such as industrial, agricultural, construction, and packaging.
Mechanical properties: PVC film has high tensile strength and impact resistance, able to withstand certain external forces without easily breaking. Its surface hardness is moderate, making it resistant to scratches while allowing surface decoration through printing or embossing.
Chemical stability: PVC film has good resistance to acids, bases, salts, and other chemical substances, especially at room temperature where it is not easily corroded. This characteristic makes it suitable for chemical packaging and anti-corrosion materials.
Processability: PVC film can be shaped and processed through methods such as hot pressing, high-frequency welding, or ultrasonic welding, and it is easy to laminate with other materials (e.g., fabric or metal foil), meeting diverse requirements.
Environmental adaptability: By adjusting the formulation of plasticizers and stabilizers, PVC film can be made into cold-resistant types (maintaining flexibility at low temperatures) or heat-resistant types (not easily deformed at high temperatures), adapting to different climate conditions.
