Blister PacksBlister packs encompass a broad grouping of pre-formed thermoplastic packaging consisting of semi-rigid plastic shells. These forms may consist of two plastic sides sealed together, as with clamshells, or may be backed with cardboard or foil as needed to best suit a given application. Though mainly used in packaging, the design of blister packs makes them popular in a number of manufacturing and retail industries.

Blister packs are preformed, clear plastic cavities formed through thermoforming. They are used for packaging small items such as food or pharmaceutical equipment. Blister refers to the pocket or cavity formed by thermoforming to cover the product. The backing is often a paperboard card or aluminum foil on which the product description is given. Blister packs are useful because they protect the product from temperature, humidity, and UV radiation.
Features of Blister Packs
Blister packs are cost-effective. There are many different types with different prices.
There is advertising space on these packs, making it easier to learn about the product.
The product is visible and can be seen and checked before buying.
Blister packaging is heat-sealed; therefore, the packs are durable and secure. No one can duplicate the product or tamper with it.
Blister Packaging Process
PVC is used to make blister packs and is sealed by aluminum foil. The complete process is given below:
The process of thermoforming is what forms the clear plastic cavities. Thermoforming, in addition to cold forming, are the two types of forming processes. In cold-forming, the material is heated at room temperature and then stamped in the mold. Thermoforming is done by heating the material at a high temperature and then placing it in the mold.
After forming, the product is loaded into the clear cavities. Products can vary in shape and size.
The next step is the sealing of the blister packs. The base and sealing material are joined together by applying pressure and temperature.
Coding is the next step. In this step, information such as batch number, expiry date, and manufacturing date is written on the blister packs to ensure convenience for the buyers.
Perforation is the process of making minor cuts or holes in the plastic or paper packaging for easy removal of a part.
The last process in blister packaging is the cutting of this packaging. Finally, a visual inspection is done to check for any broken tablet or seal. The process uses manual inspection systems along with blister positioning and rejection systems.
Types of Blister Packs
Many different types of blister packaging are on the market, each used for different purposes or client demands.
Face Seal Blister
The face seal blister pack is the most inexpensive and commonly used.
It consists of a flanged blister around the product, and the rest of the card remains uncovered.
This blister pack has a piece of heat-sealed paperboard on the back.
Full Face Seal Blister
This blister pack covers the full face of the card, meaning there is no uncovered space on the card.
This packaging offers excellent strength and durability to the card and resists corner bending.
This packaging has more aesthetic appeal to buyers, although it is more expensive.
A trapped blister pack is the same as those mentioned above, but heat sealing is not required in these blisters.
The product is entrapped between two cards. The upper card is die-cut to fit the product.
As heat sealing is unnecessary, expensive heating tools are not required for this blister pack.
The backside of the card has an opening to access the product easily.
Full Card Blister
In this type, the whale flange is wrapped around the card placed on the back of the blister pack.
The card is put into the packaging and stapled in place.
A clamshell blister resembles a clam with two halves joined together to open and close.
It has robust, strong packaging and is used to pack heavy products.
These blisters also include a hole for hanging the product.
This packaging includes feet, which help it remain upright in the aisle.
Radiofrequency, heating, or UV radiations are used for sealing this pack; therefore, they are tamper-resistant.
Due to various sealing techniques and the expensive tools required, this packaging is costly.
A mock clamshell is a one-piece blister with a card placed on the backside of the pack.
A lip extends backward to protect the edges of the card; this is also where graphics are incorporated.
It also helps in protecting the product from rough handling.
These are half the price of regular clamshells.
2- piece Clamshell
The 2-piece clamshell is a hybrid version of a mock clamshell.
A flat plastic packaging is glued onto the back of the blister pack.
The tri-fold clamshell is used for heavy and unstable products.
These blister packs have a hinged clamshell placed at the bottom of the packing.
When opened, these hinges turn into a triangular shape that helps protect unstable products from falling.
The tri-fold clamshell is the most expensive type of blister packaging.
Applications of Blister Packs
Blister packs are used widely in many industries for packing products such as food, medical equipment, consumer goods, automobile and machinery parts, toys, accessories, beauty products, electronics, medicine, and many more.
