The manufacturer of ski wax, Swix, is currently packing some of its waxes in Cefapacs
Norwegian converter Moltzaus has created Cefapac, a blister pack, made from using just paper board.
Blister packs are made to hang on a holder in the retail store and often consist of a paperboard backing plus a moulded transparent plastic front section to display the product to the consumer.
Two major benefits of the newly designed packaging improves are reduced environmental impact and less consumer rage and self-injury, from being easier to open.
‘Our development work had two starting points – environmental impact and ease of opening,’ explained Eirik Faukland, who is in charge of R&D at Moltzau. ‘To get around the well-known problem of the extreme difficulty of opening plastic blister packs, the basic concept was to replace the plastic with paperboard. What’s unique with the Cefapac solution is that we chose to replace all the traditional creases with perforations, which gives the desired openability.’
However, when perforations replace creases, the risk is that they cannot protect the pack’s contents well enough. The choice of which paperboard to use is therefore crucial.
‘Invercote’s superior tear strength is a prerequisite for a good-quality pack,’ Mr Faukland said. ‘Both the strength and how it performs in the various stages of converting and filling are crucial.’
Another benefit is that the perforations have allowed an increase in the speed of the filling lines compared with those using creased packaging blanks.
