Medical Packaging Materials Key Terms

Learn about different types of medical packaging materials
By Terri Deno A number of materials are used for medical packaging. The main concern when using these materials is the ability to keep pharmaceuticals and devices sterile. This can be accomplished through the combination of materials and packaging processes. The most common packaging materials are made from plastics, because they can be sterilized. Plastics can also provide room for air to surround a product that requires a modified atmosphere to stay functional.
 

Aseptic packaging

Aseptic packaging is a system that allows a sterilized product to be put into a sterilized package. This is performed under specific conditions to maintain sterility. Aseptic materials are often made from plastic.
Try: Medical Device Link provides information on what to consider when choosing the makeup and design of medical packaging including the reasons why aseptic packaging may need to be used.

Blister pack

A blister pack is plastic packaging that is heat formed to a specific shape. The back of the package is flat and forms a closure. Many pharmaceuticals are packaged this way, but medical devices can also be put into blister packs.
Try: National Plastics provides information on choosing the right blister pack or clamshell pack for a specific product.

Microbial barrier

A packaging system that can prevent microorganisms from entering sterilized packaging has a microbial barrier. The microbial barrier can only be created under specific conditions and with specific packaging materials.
Try: Bemis' Perfecseal provides information on the types of medical grade papers that can be used to create microbial barrier packaging.

Modified atmosphere packaging

Modified atmosphere packaging is the process of inserting a drug or device inside a package filled with a specific type of gas.
Try: Aneka Gas provides information on the different specialty gases used in modified atmosphere applications for medical packaging and other packaging needs.

Primary package

The primary package of a pharmaceutical or medical device is the sealed packaging that provides a microbial barrier, keeping the product sterile. Primary packaging is the only material that touches the device or drug.
Try: Packaging Digest provides information on the issue of creating sustainable primary and secondary medical packaging.

Sachet

Sachet packaging is a small, flexible pouch made by bonding together two layers. The sides can be bonded on three or four sides with a fine seal.
Try: PTI Packaging Systems provides information on sachet packaging machines that can be used for pharmaceutical or food products.
