Pharmaceutical Packaging systems are also classified in three class as
Type of packaging system According to layers system, classified into 3 groups
1. Primary Packaging
Pharmaceutical Packaging (as per layers of packaging Systems) systems are classified in three class Primary, secondary & Tertiary.
Primary packaging component are the components which are in direct contact with the Pharmaceutical dosage form, e.g. liners, bottles, desiccant in bottles and blister films.
Primary packaging may have a direct effect on the product shelf-life & protect the drug from the environment (moisture, gases, and light).
Example:- ampoules and vials, prefilled syringes, IV containers, blister packs, Bottles, liners, desiccant in bottles and Sachet packaging etc.
2. Secondary Packaging
- The secondary packaging system is outside the primary packaging and used to group primary packages together.
- secondary packaging are not in direct contact with the dosage form, e.g. cartons, and overwraps for blisters.
- These components generally provide protection and labelling for the primary container.
- Example: cartons, boxes, shipping containers, injection trays, etc.
3. Tertiary Packaging
A tertiary packaging system is used for bulk handling and shipping e.g., barrel, container, edge protectors, etc
Type of packaging system According to dosage capacity of the container
1. Single-unit container
A single-unit container is one that contains a only a unit quantity of medication which can be used one time.
A single-dose container is a single-unit container designed for parenteral administration only, while a unit-dose container is a single-unit container intended for solid oral dosage forms.
2. Multiple-UNIT container
A multiple-UNIT container is one that encloses multiple doses and permits multiple withdrawals of oral dosage forms, while a multiple-dose container is a multiple-unit container designed for parenteral administration only.
Others different types of containers
1.Light-resistant containers-
Drugs that undergo photo-oxidation need to be packaged in light-resistant containers. Light resistant container protects the contents from the effects of actinic light by means of opaque covering and/or stored in a dark place (USP standard: Not more than 10% transmission at any wavelength between 290-450 nm).
2.Well-closed containers
Well-closed containers protect their contents from extraneous solids and liquids and from loss of article under normal conditions of handling, storage and distribution.
3.Tight closed container-
For moisture-sensitive drugs, protects the contents from vapors, from loss or deterioration of article from effervescence, deliquescence or evaporation under normal conditions of handling, storage and distribution.
4.Air tight container:
Air tight container is impermeable to solids, liquids and gases under ordinary conditions
5.A hermetic sealed container
A hermetic container is impervious to air or any other gas under normal conditions of handling, storage and distribution. (e.g. one that is “impervious to… gas”) is necessary.
6.Tamper-evident/resistant
Tamper-evident/resistant container is fitted with a device or mechanism that reveals whether the container has been opened.
7.Child resistant container
Child resistant container is one that is difficult for children under 5 years of age to open within a reasonable time and that is not difficult for normal adults to use properly.
