Features of PVC Film
Tensile Strength
Exhibits a tensile strength of approximately 15 to 80 N, depending on the formulation and thickness, making it resistant to stretching and tearing.
Chemical Resistance
Highly resistant to a variety of chemicals, including acids, alkalis, and oils, which makes it suitable for use in chemical processing environments.
Water Resistance
Excellent water-resistant properties, ideal for applications requiring moisture barriers, such as in construction and packaging.
Thermal Properties
Softening point generally ranges between 80°C to 84°C, with a maximum continuous service temperature of about 60°C.
Electrical Insulation
PVC film is an effective electrical insulator, commonly used to protect wires and cables from damage.
Transparency
Available in clear and colored options, PVC film is often used in packaging where visibility of the product is essential.
We offer the following Product
Inkjet PVC Film
Vinyl film, or PVC Film (polyvinyl chloride), is a strong, embossable, versatile, and tear-resistant plastic film used in a wide variety of printed applications. PVC film is printable using traditional screen inks, as well as UV inkjet and Solvent inkjet inks.
Solvent PVC Film
Solvent rigid PVC film is of high quality, it has great printability. Our eco-solvent rigid PVC film is suitable for solvent / UV / Latex based printer use. Secondly, it also performs well at color consistency and impact resistance.our solvent PVC film can be widely applied in outdoor advertising display making. It is a popular advertising material for shopping mall, super market, hotel and other indoor or outdoor promotion use.

Craftsmanship of PVC Film
Calendered
In order to produce calendered pvc film, a PVC powder and a liquid softener are mixed in a fine mill. The powder is then extruded, resulting in a homogeneous mass known as a melt. The process is carried out using two counter rotating rolls which are heated to approximately 350 degrees Fahrenheit. The melt is then drawn into the gap between the mill rolls and flattens out under pressure.
In order to enhance the gloss of a calendered pvc film, changes can be made in the composition of the resin used. Lower molecular weight vinyl resins produce higher gloss levels, but they lose some tensile strength. To improve the gloss of the film, it is sometimes mixed with a small percentage of organopolysiloxane. Other options include copolymers of methacrylic acid and acrylic acid. These resins increase the cost of finished films.
Compounding
When PVC foil is produced by polymerizing oil, the material undergoes several processes that require an auxiliary agent. The auxiliary agent is a chemical compound that consists of several repeat units linked head-to-tail. The theoretical molecular weight range of PVC ranges from 30,000 to 95,000. Both the average molecular weight of the film and its distribution of molecular weight play a role in its properties. However, this chemical compound differs from the theoretical chain, due to the presence of auxiliary agents in the process. The inorganic pigments lack the colour strength of organic pigments, and the latter is carcinogenic.
The particle size of the plasticiser used in the compounding process is of great importance. The particle size is important because it affects the speed at which polymer is discharged during processing. If the particles are too fine, they will absorb plasticizer less evenly during the dry blending process. The typical particle size of commercial suspension resins is 50 to 150 micrometers. This can result in gels, which are large resin particles that failed to fuse during the processing. They show up as small spots on the finished film.
Heat stabilisers
The use of heat stabilisers in a pvc film increases its resistance to heat ageing, sunlight and weathering. Stabilisers are additives that increase the physical properties of the film and influence its cost. Typically, these stabilisers are supplied in blends, containing metal soaps, salts, and organic compounds. Their choice depends on the final use of the PVC film, regulatory approval requirements, and cost.
Different thermoplastic polymers undergo different behaviors at different temperatures. The IR fingerprint of a sterilized PVC film is different from that of an unsterilised film, suggesting that the presence of thermal stabilisers affects the thermal stability of the PVC film. Further, heat stabilizers in a PVC film exhibit different distribution patterns, with the former decreasing as the temperature increases. The same trend is observed for calcium and zinc carboxylates, which likely correlate to the migration of these additives in a material.
