Different Materials Used In Blister Medical Packaging

Blister cards, sometimes known as single dose packaging or blister packaging, is a widely popular option for both prescription medications as well as over-the-counter medications.

The Benefits

This option in medical packaging offers several advantages to pharmaceutical manufacturers as well as consumers. For the pharmaceutical companies, it offers ease of serialization for compliance with regulations, tamper-proof packing, enhanced protection of the medication as well as consumer-friendly packaging.

For consumers, the blister packaging provides easy management of dosages, convenience in storing and transporting medication and increased confidence the security and tamper-proof aspects of packaging.

When choosing blister medical packaging for any type of prescription or over-the-counter medication, there are several choices that come into play. Understanding the options will help you to choose the right combinations.

Protection from Light

While most medical packaging provides a clear forming material to make the pocket for the pill, tablet or capsule, with some medications it may be important to use an aluminum foil. This will be required if light exposure will have an impact on the medication.

Clear pockets are typically made from polyvinyl chloride or polypropylene. They are made through a process known as thermoforming. This uses heat to soften the plastic to form the desired pocket shape.

Sealing Options

The backing has to be sealed to the sheets of pockets after the medication has been dropped into place. This is typically done through exposure to heat as well as rollers or plates. The rollers or plates provide pressure for the heated material, forming a complete seal or bond between the front and the back of the packaging.

Sealing can be completed across the entire surface or just around the edges of the pockets. Both are acceptable for most medications, but for childproofing the continual seal option is most often required.
