The term “blister packaging” refers to a more specific process of product packaging, known as thermoforming. This is a process that takes a sheet of plastic and heats it to a temperature where it is then able to be molded into a desired shape. The “blister” is the pocket that is formed that completely covers the product.
Depending on the product, blister packs can refer to various designs where the product is securely enclosed inside the blister, which is then heat-sealed onto an adhesive coated paperboard card or foil backing.
Because there is such a wide range of blister packages needs, there are a several to choose from. Here are a few of the most common types of blister packages available.
Face Seal Blister
This type of packaging is common for large volumes, generally around 25 to 500 thousand. This packaging uses a flanged blister that completely surrounds the product and then is heat-sealed onto a piece of thick paperboard. The seal is only on the flange while the rest of the packaging is left uncovered.
Full-Face Seal Blister
This design is similar to that of the face seal, but instead of only covering the product, this design covers the entire face. This is done to provide extra durability and strength, prevent bent corners and reinforce the hang hole. Additionally, consumers perceive a full-face seal as a more expensive product due to its appearance.
The same idea as the face seal applies to the trapped blister design. The biggest difference is that instead of being heat-sealed onto a paperboard card, the blister is trapped between two cards. There is a die-cut hole in the top card to accommodate the blister. Because the blister is trapped between two cards, there is no need to use an expensive heat sealing tool to secure the seal on the blister.
Full Card Blister
The full card blister combines the two previous designs by creating a blister that extends the full face of the card. Instead of being sealed to the card or being trapped between two cards, there are flanges that wrap around the edges of the card. This allows the card with the product to slide into the blister and then the flanges are secured to the card, usually with staples.
Clamshells are quite popular. They are a container that has two halves hinged together, allowing it to open and close. Ideal for heavier products, clamshells are robust. Clamshells are designed to snap shut with a button. Other designs can be sealed using heat, radio frequency or UV light. When a clamshell is heat-sealed, it can be difficult and often dangerous for consumers to open. On the other hand, a heat seal makes them tamper-resistant, which can be appealing depending on the product inside.
A tri-fold clamshell is perfect for products that are heavy and unstable when packed in traditional clamshell packaging. Instead of having one hinge, a tri-fold clamshell has two hinges that create a wide triangle at the bottom when folded up. This provides the product with a solid, steady bottom to stand on.
