The term(s) "blisters, blister packs, plastic blisters, custom plastic blisters, or blister packaging" are essentially generic terms which refer to the style, type and method of packaging. This type of packaging is created via the process of thermoforming. (For more information regarding the process and explanation of "thermoforming" please visit www.thermo-forming.org) A "blister pack", or "blister packaging" consists of two distinct parts or halves. The "blister" portion of the package describes a clear plastic "bubble’ or "shell" which has been designed to fit the intended product or products. The "seal" area(s) of a blister are called the "flange". The other half of the "blister pack" consists of a paper or foil backing which contains a heat activated adhesive. This adhesive is activated by secondary sealing equipment and tooling through heat and pressure. During this process the product is "sealed" between the plastic blister and foil or paper backing creating a tamper evident, product encapsulated package. Blister packaging is one of the most popular forms of packaging for both the pharmaceutical and retail environments. Its’ popularity largely stems from the fact that it allows the product(s) to be see, can be easily automated and is a relatively low cost packaging solution. Many pharmaceutical and drug manufacturers use a "form-fill and seal" blister application. This describes the process in which a machine will form the blister or blisters, fill the blisters with the intended product and then seal the product in the blister with either a paper or foil lid of some sort. The fact that this process is done on one machine and requires very little human involvement after start up makes "form-fill and seal" an ideal vehicle for the packaging of drugs and medication. There are however distinct limitations with regards to the blister size and design but again, when dealing with either medication or drugs "from-fill and seal" is still the best method for packaging these items. The other method of blister packaging is generally best suited for small to high volume packaging of retail or consumer goods. This process allows for more flexibility with regards to the blister design and can accommodate larger and heavier objects than can a "form-fill and seal" operation. This type of blister packaging application does require secondary seal equipment and tooling, but change over from "job to job" is quicker and easier than with a "form-fill and seal" application.
