PVC Blister Film & Rigid PVC Sheet for Blister Packaging

About PVC Blister Film & Rigid PVC Sheet for Blister Packaging

Rigid PVC blister film is a plasticizer-free, calendered PVC sheet used as the forming web in blister packaging. When heated and vacuum-formed on a blister machine, it shapes into cavities that hold and protect the product, which is then sealed with lidding foil or a card. Clear grades give full visibility of the packaged item, while colored and opaque grades add brand appeal. It is widely used for tablets and capsules in medicine packaging, and for hardware, toys, stationery, cosmetics and small consumer goods. Consistent thickness, good thermoforming performance and stable sealing behavior are the key quality points for high-speed packaging lines.

How to Choose

  • Film thickness matched to cavity depth and product weight, typically around 0.2 to 0.4 mm for standard blisters
  • Roll width and length to match your blister machine's forming format
  • Color and clarity: transparent, white or custom tinted for brand presentation
  • Grade for food contact or medicine packaging, with the relevant compliance documentation
  • Surface finish and printability if you print or emboss the film before forming

FAQ

Q: What thickness of PVC blister film do I need?
A: Thin films around 0.2 mm suit shallow cavities and light products, while 0.25 mm and above are used for deeper cavities and heavier items that need stronger push-through rigidity. Match the gauge to your product size and cavity shape.

Q: Is rigid PVC film suitable for food or medicine contact?
A: Yes, when you select a grade produced for those applications. Food-contact and medicine-packaging grades are manufactured to strict hygiene standards, and you should confirm the relevant compliance documents with your supplier.

Q: Can it form deep cavities?
A: Rigid PVC is known for excellent thermoformability and can draw deep, complex cavities on standard blister machines. For very deep draws or added barrier protection, laminated structures such as PVC/PVDC can be specified.

Q: What width and color options are available?
A: Films are supplied in rolls cut to your machine width, in transparent, white or custom colors. Give your blister machine model and cavity layout to confirm the correct roll size and grade.
