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 Machine
is 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 Machine shop online rather offline. There are lots of online retailers offering good discount on different pharmaceutical devices.
