As the UK's leading supplier of packaging materials to the pharmaceutical and healthcare industries, Alcan Packaging Cramlington has a close understanding of the demanding requirements for this primary component.

Blister packs allow for the hygienic packaging of solid dose presentations such as tablets, pills, capsules and also medical devices.

Clearly the first objective achieved is functional, ensuring products are suitably protected from contamination and meet shelf-life requirements.

Blisters offer advantages of convenience and improved patient compliance, as well as providing an attractive, finished, complete pack direct from the manufacturer to the end user.

In addition, suitably printed, they allow you a superb marketing opportunity to establish your brand identity in the patient's mind, improving the chances of your product gaining repeat purchase/prescription

Push-through Lidding Foil

Conventional blister packs are created by thermo-forming a web of plastic film, normally PVC, into pockets. These are filled with the pharmaceutical product e.g. tablet or capsules and then sealed using heat and pressure.

The product is removed from the pack by then consumer pressing it through from the pocket side through the foil.

Packaging materials are supplied in reels - dimensions depend upon the packaging machine being used. Close links with all major blister machine manufactures are maintained by Alcan Packaging, our R&D centre in Neuhausen, Switzerland and our sister companies to ensure that we remain at the forefront of new developments in this field.
