PVC Film Roll
PVC roll material (Polyvinyl Chloride Waterproof Membrane) is a polymer material made from polyvinyl chloride resin as the main raw material, with added plasticizers, fillers, antioxidants, and other additives. It is processed through mixing, extrusion molding, or calendering.
PVC (Polyvinyl Chloride) film roll is a widely used thermoplastic material that is broadly applied across various industries due to its durability, flexibility, and adaptability.
PVC (Polyvinyl Chloride) film rolls are mainly produced through calendering or extrusion processes and are available in rigid and flexible formulations. Thickness ranges from ultra-thin (approximately 0.003 inches/0.076 mm) to semi-rigid (approximately 0.030 inches/0.76 mm), and widths range from less than 1 meter to over 2 meters. They are typically supplied in continuous rolls of several hundred to several thousand feet. These films feature high clarity, excellent dimensional stability and toughness, outstanding chemical resistance, moisture resistance, and abrasion resistance, while maintaining cost-effectiveness and ease of processing.
Types of PVC Film Rolls
PVC films are categorized by flexibility and application:
Rigid PVC Film
- Thickness: 0.12–3.0 mm.
- Used for thermoforming (e.g., blister packaging, automotive parts) and printing.
- High strength, anti-static, and flame-retardant properties (UL94 V-0 certified).
Flexible PVC Film
- Thinner (0.003–0.5 mm), used for banners, food wrap, and protective covers.
- Flexible and capable of wrapping irregular shapes.
Rigid PVC Film vs. Flexible PVC Film
- Rigid PVC film contains no plasticizers. Compared with flexible PVC film, it has higher yield strength (4, 500–8, 700 psi) and Young’s modulus (~490, 000 psi).
- Flexible PVC film contains plasticizers, which lower the glass transition temperature (Tg) and enhance flexibility (elongation at break up to 300%), making it suitable for conformable packaging and strip curtains.
Film PVC Roll Material Properties
PVC film is a thermoplastic polymer that can be reprocessed through heat treatment and is suitable for calendering or extrusion production. Main properties include:

PVC Film Roll: Uncoated Film vs. Coated Film
PVDC-coated PVC film (double-layer/triple-layer structure) offers excellent moisture and oxygen barrier properties (e.g., 250 µ PVC/40 gsm PVDC), commonly used in pharmaceutical blister packaging.
Uncoated PVC film already provides good moisture resistance and certain gas barrier properties, making it an ideal choice for food packaging and industrial packaging.
PVC Film Roll Manufacturing Process
Calendering
Vinyl compounds are pressed between heated rollers; the spacing between rollers determines film thickness, and finishing rollers give the film either a glossy or matte surface.
Extrusion
Forced extrusion pushes the melt through a flat die, followed by polished or textured rollers to achieve the desired surface finish and thickness consistency.
PVC Film Roll Physical and Mechanical Properties
Clarity and Surface Finish
- High-clarity grades feature mirror-like gloss and near-optical transparency, ideal for product display.
- Matte or textured films reduce glare and fingerprints, making them well-suited for decorative overlays.
Strength and Durability
With tensile strength up to 55 MPa and excellent tear resistance, PVC films ensure long service life in packaging and protective applications.
PVC Film Roll Chemical and Barrier Properties
Chemical Resistance
Resistant to acids, alkalis, oils, and most solvents, making PVC film suitable for industrial liners and protective covers.
Moisture and Gas Barrier
Features low water vapor transmission rate; PVDC coating further reduces moisture and oxygen ingress for sensitive products.
Thermal Stability
Maximum continuous use temperature is around 60°C; above this temperature, softening begins without the need for additional stabilizers.
Flame Retardancy
Inherent chlorine content provides flame resistance; special grades comply with UL 94 V-0 electrical insulation rating.
PVC Film Roll Processing and Functional Features
Printability
Compatible with screen printing, offset printing, flexographic printing, thermal transfer, digital printing, and UV-curable inks; widely used for point-of-sale graphics and product labeling.
Thermoforming and Die-Cutting
Rigid and semi-rigid grades can be thermoformed into deep-drawn blister packs and custom trays; soft grades can be die-cut into pouches and bags.
Shrink Film
PVC shrink film (thickness approx. 0.03 mm) conforms tightly to packaged goods under heat, enhancing display appeal and tamper resistance.
Main Applications of PVC Film Roll
PVC Film Roll in Blister Packaging
PVC Film Roll (polyvinyl chloride film roll) is widely used in blister packaging, especially in pharmaceutical, personal care, electronics, and consumer goods industries.
Blister packaging is a method of sealing products between a transparent plastic blister and a backing board. PVC Film Roll is typically used as the forming film for the blister, serving to:
- Form the blister shape through heat and vacuum or pressure forming
- Provide protective support for the contents
- Maintain excellent display effects and moisture resistance
