What uses is PVC film?


The third most popular synthetic plastic is polyvinyl. It's also known as poly(vinylchloride) or PVC. It is versatile and economical, with excellent weathering and impact strength. It is easy to extrude, calendered, and die-cut. It can also be printed with offset and conventional screen printing methods. It can be either clear or matt or colored or white depending on its composition. It can also be rigid or flexible. You can also easily heat it to reprocess.

PVC's backbone is quite polar and has strong intermolecular interactions. PVC is therefore rigid at room temperatures. It can however be softened or plasticized by mixing with plasticizers during fabrication. Vinyl polymers have a lot of versatility.

Flexible vinyl film is made from plasticized PVC, while rigid vinyl film is made of PVC without any plasticizer.

Flexible Vinyl Film

Flexible vinyl film is not only resistant to oil and grease, but also oxygen permeable. It is also very flexible, clear and puncture-resistant. Flexible PVC is suitable for food packaging, which can keep meat and other perishable foods fresh (if FDA approved). Plasticized PVC is more resistant to chemicals and melts at lower temperatures than rigid vinyl, but has a higher ultimate tensile strength.

Vinyl Film Rigid

Rigid vinyl is also known as unplasticized Polyvinyl chloride (uPVC) and it's a strong, lightweight film. It is a durable, low-cost film that is resistant to many chemicals. uPVC can generally be used at temperatures of up to 60 degrees Celsius. Flexible PVC has lower tensile strength and modulus, while uPVC has a higher tensile and modulus. However, it is more susceptible to impact cracking and can be subject to stress cracking, depending on the environment.

PVC comes with a few limitations. The plasticizer can soften under hot and cold temperatures, and harden in cold. This can lead to changes in properties that can affect the seal's strength. PVC can also release small amounts of hydrogen chloride in the air. When heated, it will also produce carbon deposits on the sealing equipment. PVC shrink-wrap must be sealed with good ventilation.


PVC film can be used to shrink and stretch industrial and consumer goods, and also as pallet wrap. However, it is more affordable than polyolefin films. Bags, liners and bottle sleeves, adhesive tape backing, labels and blood bags are some other uses of PVC film. bags. When improved moisture resistance properties are needed, it is often PVDC coated.

PVC approved by the FDA is a good choice for packaging fresh red meat. It is semi-permeable which means that it has just enough oxygen permeable so meat products can be kept fresh and their bright red color. PVC is used when transparency is important.
