What is PVC Film?

Definition and basic composition

PVC film is primarily made from polyvinyl chloride, derived from a combination of chlorine, carbon, and hydrogen. Its versatile nature stems from its ability to modify its flexibility by using plasticizers for softer films or leaving it unaltered for a more rigid finish.

Types of PVC: rigid and flexible

  • Rigid PVC: Often used in construction for pipes and window frames, rigid PVC is tough and not easily bent.
  • Flexible PVC: Enhanced with plasticizers, this type is bendable and used in everything from medical bags to inflatable pools.

Comparison with other plastic films

PVC film is generally heavier and more resistant to tearing and puncture than other polyethylene films. This makes it a popular choice for applications requiring more durability.

The Manufacturing Process: Versatile PVC Film

Raw materials used

The primary materials for making PVC film include polyvinyl chloride resin, various additives, and plasticizers (for flexible PVC).

Steps in production

  • Mixing raw ingredients: PVC resin is blended with chosen additives to obtain specific qualities.
  • Melt processing: The mixture is melted and passed through a die to form sheets.
  • Cooling and rolling: The extruded sheets are cooled and rolled into large reels.

Quality control and safety standards

Every batch of PVC film undergoes rigorous testing to ensure it meets strict safety and quality standards, such as those specified by ISO and ASTM.
