What is Trapped Blister Packaging?

Traditional face seal blister and clamshell packaging are being replaced by trapped blister packaging, which is a more sustainable and high-performing option. A hybrid paper and plastic package, trapped blister packaging is a hybrid paper and plastic package. The product is protected with a thermoform blister sandwiched between two cards. Trapped blisters provide the protection and shelf appeal you seek for your package without the added cost, thanks to their eco-friendly materials and low plastic content, as well as a secure yet user-friendly design.

Most CPG firms have been using trapped blister packaging to successfully promote their product lines, and it has several advantages over other packaging options.

  4. Packaging of pharmaceutical products
  5. Packaging of stationeries


  1. Provides a better visibility of the product
  2. It is a cheap way of sealing your product nicely
  3. It offers safe protection of your products from environmental hazards.

  5. Minimal environment interference ensures the product remains fresh and safe.
  6. Allows product inspection before it is purchased and consumed by the consumer. 

Raw materials

The most common materials used to make trapped blister packaging are plastics, which include:

  1. Polyethylene Terephthalate (PETE or PET)
  2. High-density Polyethylene (HDPE)
  3. Polyvinyl Chloride (PVC)
  4. Polypropylene (PP)
  5. Polystyrene (PS)
  6. Polyvinylidene chloride (PVDC)
  7. Polychlorotrifluoroethylene (PCTFE)
  8. Cyclic Olefin Copolymers (COC)
  9. A paperboard


  1. Environmentally friendly polymers and cardboards are used in the production of trapped blister packaging.
  2. Trapped blister, on the other hand, covers the product with a blister on one side and cardboard on the other.
  3. It offers a tamper-proof packaging solution for your product. Trapping the product in a blister packaging helps in safeguarding from external brazening of the product.
  4. Trapped blister packaging can be used instead of clamshell packaging depending on the product.
  5. Thermoforming trapped blister packaging entails heating the plastic material and moulding it into the desired shape. After that, a cardboard is used to cover the trapped blister pack, which is then sealed with a specific adhesive covering.
  6. Recycle and reuse trapped blister packs is possible.
  7. You can hang your product from something like a rod using hanging trapped blister packing. This saves storage, which is very useful in a store.
  8. A heated seal coating is used to close trapped blister packages. A unique glue is activated by applying pressure and heat, which securely keeps the card and the blister together.
