packaging and holograms, have also emerged.
Importance of Pharmaceutical Packaging Materials
Pharmaceutical drugs require more than normal care while packaging than most of the other products need because any type of carelessness or usage of low quality packaging products may lead to destruction of the drugs or alteration in their properties due to the contact of oxygen and moisture that in turn may even cause death of patients. Some of the advantages of quality pharmaceutical packaging materials can be listed as below:
-
Pharmaceutical packaging materials protect against all harmful external influences that can alter the properties of the drugs thus preventing any type of chemical deterioration.
-
They protect the medicines against physical damage.
-
They also protect the pharmaceutical products against microorganisms and other biological contamination.
-
Pharmaceutical packaging materials can carry the correct information and identification of the drugs.
-
Pharma packaging materials extensively help in portion control. Single dosage packaging contain a precise amount of contents.
-
They are also tamper evident and anti counterfeiting.

Types of Pharma Packaging Materials
Secondary Pharma Packaging Material
Pharmaceutical packaging supplies- like the other packaging products- may be divided into three main types-
Primary Pharma Packaging Material (or Critical Packaging Material);
Secondary Pharma Packaging Material (or Non Critical Packaging Material); and
Tertiary Pharma Packaging Material (also a Non Critical Packaging Material).
Primary packaging material is the one that first envelops the pharma product and holds it. This is generally the smallest unit of distribution which is in direct contact with the drugs contents. Secondary packaging material covers the primary packaging- for grouping primary packages together. These can be explained as the boxes or cartons that contain the pharmaceutical blister foils or the strip foils and are also used as display units with labels and other instructions. Tertiary packaging is used for bulk handling, warehouse storage and transport shipping. Some of the popular types of primary pharma packaging materials have been explained as under.
Pharma Blister Packaging foils
Blister foils are one of the common packaging of tablets and
capsules. Blister packaging helps to protect the medicine from
humidity, moisture and other environmental problems. They help in
keeping the medicine fresh. Hard aluminum alloy is generally used to
make the foil. However, the packaging has to undergo various product
and package stability tests so as to make the right package, using
the right material and manufacturing process required for that
particular drug. The films are given different coatings.
Pharmaceutical Strip Foils
Strip foils are ideal for tablets and capsules packaging. They are
used for drugs ranging from light sensitive to highly sensitive.
They are usually made of soft , annealed aluminum alloy with
colorless LDPE as sealant. These foils are available in reel form ,
jumbo roll or cardboard carton.
Cold Formed Laminates
Cold-formed laminates are used for packaging of medicines. This
type of packaging is made of
aluminum foil. These are designed in
peelable, formable foil structures without cracking or de
lamination. The cold forming packages are available with peelable
sealants incorporated into the forming web and are ideal for
dual-formed packages as both top and bottom webs are formed in the
package.
