Blister Packing Machines And Their Use In The Pharma Industry

Blister packs and plastic products are quite useful for packaging in the pharmaceutical industry. Both of them have a set of advantages that no other material can afford to give. From their ease of use to the varieties, there are plenty of advantages.

There are basically four types of production of blister packaging. They include thermodynamic, cold forming, Polyvinyl Chloride (PVC) and Cyclic-olefin-co polymers (COC) or polymers (COP). However, none of these types affects the functionality or even the look. Their main application is the unit packaging that we can see in pharmaceutical tablets, capsules and lozenges.

Blister packing machines are commonly used as unit-dose packaging for pharmaceutical tablets, capsules or lozenges. Blister packs can provide barrier protection for shelf life requirements, and a degree of tamper resistance. In the US, blister packs are mainly used for packing physician samples of drug products or for over-the-counter (OTC) products in the pharmacy. In other parts of the world, blister packs are the main packaging type since pharmacy dispensing and re-packaging are not common. A series of blister cavities is sometimes called a blister card or blister strip as well as blister pack. The difference between a strip pack and blister pack is that a strip pack does not have thermo-formed or cold formed cavities; the strip pack is formed around the tablet at a time when it is dropped to the sealing area between sealing moulds. In some parts of the world the pharmaceutical blister pack is known as a push-through pack (PTP), an accurate description of two key properties (i) the lidding foil is brittle, making it possible to press the product out while breaking the lidding foil and (ii) a semi-rigid formed cavity being sufficiently collapsable to be able to dispense the tablet or capsule by means of pressing it out with the thumb.

The main advantages of unit-dose blister packs over other methods of packing pharmaceutical products are the assurance of product/packaging integrity (including shelf-life) of each individual dose and the ability to create a compliance pack or calendar pack by printing the days of the week above each dose.

Blister packs are created by means of a form-fill-seal process at the pharmaceutical company or designated contract packer. A form-fill-seal process means that the blister pack is created from rolls of flat sheet or film, filled with the pharmaceutical product and closed (sealed) on the same equipment. Such equipment is called a blisterline. There are two types of blister machine' design: rotary and flat-plate.

To buy affordable blister packing and capsule filling machines shop online rather offline. There are lots of online retailers offering good discount on different pharmaceutical devices.
