Blister packaging seems to be growing in popularity as pharmaceutical packaging machine manufacturers look for solutions with heightened protection against oxygen, moisture and contaminants. Opaque blisters also protect light-sensitive products from UV rays.
Blister packaging machines seal products in a pre-formed cavity or pocket made from a formable web, usually made of PET (polyethylene terephtalate) or PVC (polyvinyl chloride). This usually has a backing of paperboard or a lidding seal of aluminum foil or plastic. Another type is constructed with foil as both the blister web and the lid or seal. This type is usually created by cold stretching.
Today, blister packaging is the preferred packaging for the pharma industry, used for packing tablets, capsules, vials, ampoules, syringes and liquid products. It is also increasing popular for packing some foods and small consumer goods.
The main advantages of blister packaging include:
Blister packs not only protect the product against light, oxygen, humidity & contaminants, it provides protection against mishandling and tampering. Since the product stays securely sealed from the external environment, shelf life in extended, making it safe and suitable for long-term storage and display.
Blister packaging offers a range of colours and finishes. The card option also allows manufacturers clean space to include branding, instructions, product information, etc. in an attractive, easy-to-follow way. All this helps the product to stand out in retail outlets, build brand and increase customer loyalty.
Higher packaging speeds and reduced costs make blister packaging a more cost-effective solution. Blister packs eliminate the need for additional cartons, thereby reducing the cost of packaging. There are several different types of blister packaging – Face Seal, Trap, Mock, Slide and Interactive. Each one has its unique qualities and price points, from entry level to high end.
With a see-through plastic front, these containers make the encased product perfectly visible to the consumer. Doing so provides reassurance that the amount of product contained is as advertised and that all pieces are accounted for. Visibility promotes retail display, and since customers can view the item but not touch it, is safeguarded against thieves and tampering.
The product units are individually sealed and therefore individually protected from tampering. Any form of tampering is immediately visible.
Helpful & easy to use
For consumers, blister packaging provides clear space for instructions and other important data. It offers patients a clear individual dose, making it easier for patients to track whether they have taken the prescribed drug on a given day. To use, consumers just have to pop the pill out of the package which can be done quite easily. Drugs not consumed remain in the original package, fully protected. Blister packs are also easy to carry when travelling – ideal for today’s on-the-go lifestyle.
All plastic blisters are thermoformed, so manufacturers can customise every design to the product. Regardless of the size, shape or number of items contained in the blister pack, it can be customized to fit the needs of the product.
From medicines & electronic items to cosmetics & toys, SD cards & batteries to toothbrushes & dental floss, a blister pack makes a great marketing and packaging tool. If you have a product that could benefit from blister packaging, contact Nichrome.
