Larger Blisters for Medical Devices

By Marie Redding, Freelance Writer

More patients are self-administering medications at home, which suppliers say is another reason for the increase in blister use.

“There has been a huge increase in the popularity of pens and other devices used for home injection, and this is creating a whole new market for blister packaging,” says Keith Bailey, regional sales manager at Körber Medipak. “Ten years ago you went to the doctor for a shot. Now, you can have a month’s worth of injections shipped to your door, and all of these devices are going into blisters.” The convenience of self-injecting drugs will remain important,” he says.

Uhlmann's UPS 5 is capable of handling large formats, such as forming deeper blisters for medical devices.

Packaging a medical device often requires a blister with a deep cavity, which can be produced on a large format machine, such as MediSeal’s CP 500. “The demand for this machine has been continually increasing,” says Bailey.

The Modular UPS 5 Blister Machine, by Uhlmann Packaging Systems, is another option. It has a large format area, perfectly suited for solid and liquid products, and has a deep forming depth of up to 40 mm.

Ben Brower, vice president and sales director, Pharmaworks, also says there has been an increase in the number of medical devices packaged in blisters.

“Our machinery needs to be able to handle deeper blisters now, while maintaining speed and efficiency. We are taking this into account now, for every new machine we design, and make sure they will be able to run a deeper blister, efficiently,” he says.

Different types of films are required to produce a blister with a deeper cavity. “Medical devices require a deeper blister, making it necessary to use a thicker film,” he explains. “This is to ensure that the film holds up well when it is thinned during the thermoforming process,” he explains. Perlen’s Tristar 180 is a thick high-barrier film designed to protect more-sensitive products.
