The different types of pharmaceutical and medical device packaging
Let’s start with the basics. As you’ll know, pharmaceutical and medical device packaging is varied and complex. However, it is mainly dominated by three types of packaging which include:
- Medical (WIP) trays: allow pharmaceutical companies and medical device manufacturers to safely store and transport products together. WIP trays can also be used for the final delivery of pharmaceutical and medical devices such as syringe barrel trays or electrical components.
- Pharmaceutical packaging for prescription and over the counter distribution: encompasses packaging that contains OTC pharmaceutical products or drugs. Pharmaceutical packaging helps protect the products from damage and contamination during shipping.
- Sterile barrier medical device packaging: this packaging is for medical products such as heart transplant kits, chemotherapy kits, and catheters that require sterile barrier medical device packaging as it protects medical devices during sterilization, shipping, and during use in hospitals. Implantable products such as diabetes drug delivery devices also require this type of packaging for protection. Popular types of medical device packaging include – peel pouches (most popular as it’s one of the most cost-effective ways of packaging disposal for medical devices) foil sachets, barrier packaging and thermoformed blisters and lids.
Important specifications of pharmaceutical and medical device packaging
Pharmaceutical and medical device packaging need to meet strict specifications in order to ensure patient safety. Medical packaging must have rigorous testing procedures to test requirements and specifications.
Ensuring the packaging has minimum thickness is often a vital specification for pharmaceutical and medical device packaging. This is because three common sterilization processes such as ethylene oxide sterilisation, gamma sterilisation, and autoclave sterilisation, kill all forms of bacteria and are harsh on plastic materials used in packaging. So, in order to ensure the packaging maintains its sterility and physical properties, minimum thickness is required. If it isn’t, the sterility of the packaging is compromised and so the sterility of the device will be considered unsuitable as well.
So, what amount of thickness is acceptable? Most packaging has a minimum thickness of 0.005 inches but testing sometimes shows that a minimum of 0.003 inches or even 0.010 inches is considered to be okay to use.
Sturdy seals are also- of course - vitally important and must have the strength to hold the items and not become undone as this would risk contamination to the medical products or devices.
Good medical device packaging needs to arrive at the destination free from holes, tears, or missing seals. It must also be able to remain for years in storage without the drug or device having their composition altered.
