Blisters and Clamshells

Blister and Clamshell  packaging are primarily used for small consumer goods, foods, nutraceuticals, and pharmaceuticals.  The primary component of a blister or clamshell is a cavity, or pocket, made from a formable web, usually a thermoformed plastic.

Blisters usually have a backing of paperboard or a lidding seal of aluminum foil or plastic. A blister that folds onto itself without the backing or lidstock is a clamshell pack.  Blister packaging is useful for protecting products against external factors such as humidity or light.  Clamshells are often used as a pilferage deterrent because of their size and rigid seal.

SPS works with qualified suppliers to create custom thermoformed blisters and clamshells along with printed insert cards for your product’s packaging.  This custom packaging is molded to your product for a one-of-a-kind fit. 

We also offer a wide selection of stock blisters and clamshells available for same-day shipment. We can provide customized insert cards at affordable prices without a tooling cost or set-up fees.
