Today, we live in an era where showcasing products is all about being competitive and creative. Many times, a consumer’s choice relies not on the product’s quality but on its packaging. In addition to this, packaging is essential for protecting items, deterring theft, and improving the consumer experience. Among the many packaging options, blister pack have become one of the most adaptable and efficient choices for businesses in various sectors. These clear, sturdy packaging solutions have changed the way products are shown, safeguarded, and sold in stores.

What are Blister Packs?

Blister packs are a unique kind of packaging that features a molded plastic pocket for a product, sealed to a backing material like cardboard, aluminum foil, or plastic film. The word “blister” refers to the bubble-like form of the clear plastic part that encases the product, forming a protective dome or cavity around it.

Blister pack are made through a process called thermoforming, where plastic sheets are heated and molded to form the right cavity size and shape. This cavity is filled with the product and sealed to a backing card or film using heat, pressure, or adhesive. The final product is a secure, tamper-evident package that displays the product and offers great protection against moisture, contamination, and physical damage.

What is a blister pack in terms of materials? 

Typically, the plastic component is made from materials like PVC (polyvinyl chloride), PET (polyethylene terephthalate), or PETG (polyethylene terephthalate glycol), chosen for their clarity, durability, and forming properties. The backing material varies depending on the application, with cardboard being common for retail products and aluminum foil preferred for pharmaceutical applications.

Blister packs are adaptable due to their customizable features. They can be shaped and sized in many ways to suit different products. This makes them perfect for a range of items, from small tablets to larger electronics, guaranteeing the right fit and protection for every application.
