Blisters & Clamshells


Blister and Clamshell are terms for pre-formed plastic packaging used primarily 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 will 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 products are 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.  These custom products are molded to your product for a one-of-a-kind fit.  We also have a wide selection of stock blisters and clamshells available for same day shipment which eliminates the tooling costs of custom packaging.  Along with this we can provide customized insert cards at affordable prices without the tooling costs and set-up fees our competitors charge.

SPS also offers self-sealing and eco-friendly sustainable package designs.  Give us a call today and let one of our SPS Packaging Specialists review your product line and determine what blister and clamshell designs are the best for your products.
