To ensure consistent and accurate seal integrity a load cell provides real time information on seal pressure. A secondary high-speed sensing system will detect any foreign object between upper and lower seal plates. If an object is detected, the sealing cycle will instantly stop and reverse plate travel. Another safeguard on the TF1pro is a retracting seal plate—if web motion stops, the upper seal plate retracts to the rear so that the web won't be exposed to unnecessary heat.
The blisters are then perforated and die cut by the inverted die punch. The reject/transfer station uses a vacuum arm to lift the “good” blisters onto the outfeed conveyor while “bad” blisters simply drop down into the reject bin, which ensures consistent and accurate ejection. Positioning the die cutter in this way also provides space at the end of the web for direct coupling of a cartoning machine. Blisters can be manually packed as well.
PACK EXPO Connects continues to bring the industry together in record numbers this week with over 17,000 attendees as of Wednesday. Even after the PACK EXPO Show closes, informative Jumpstart sessions, Innovation Stage presentations, and exhibitor live demos will be available on-demand until March 2021. Be sure to register today so you don't miss out!
Blister packaging, or blister packs, are pre-formed packaging materials composed of a thermoformed plastic cavity and a pliable lid. In this type of packaging, the product is placed in deep-drawn pockets or cavities resembling a blister. A backing material or lidding mates to the flat area of the plastic cavity enclosing the product inside. Bonding the two structures is a heat-seal coating adhesive. Blister packaging has various types depending on the application. The most popular use of blister packs is packaging pharmaceutical products such as pills, tablets, capsules, and lozenges. Because of its low cost, cheap raw materials, and high operating speed, they are also used for packaging consumer goods such as foods, electronics, toys, and tools. Enumerated below are the benefits of using blister packaging.
“The conversations between Rohrer and Starview have been going on for quite a while,” said Sarah Carson, Head of Marketing at Rohrer. “But in the past year or two the pressure on consumer packaged goods companies to deliver on ambitious sustainable packaging goals by 2025 was increasing considerably, to the point that customer demand started to really ramp up. That included one significant customer who was so serious about the idea that it gave us a powerful business reason to invest in the R&D that it was going to take. Fortunately, we had already established a great partnership with Starview from the machinery side.”
“We had both intended to actually launch this last year at PACK EXPO in Chicago,” said Robert van Gilse, Director of Sales and Marketing at Starview. As we all know, COVID-19 put the kibosh on that plan. But then when customer interest in the concept grew the way that it did, says van Gilse, “We knew it was time to get really serious.”
On the machinery side, a key goal throughout the development process was to come up with tooling that would make it possible for existing customers already running automated Starview bp-260a/e automatic platen alu-pvc alu-alu blister packing machine to get in on the all-paper blister option by simply adding an auxiliary feeder to any one of Starview’s FAB (Fully Automated Blister) Series of machines. With this tooling in place, a flat paper blister is picked from a magazine feed and, thanks to precision scoring done by Rohrer, is erected and made ready to receive whatever product the customer happens to be packaging. Then it’s just a matter of applying the blister card and heat sealing card to blister.
