Blister cards are the backbone of blister packaging. Together, the blister and blister card provide a beautiful, highly visible presentation of your product. Blister cards can be single cards, but also used in other variations such as the front & back card combination, or the fold-over card. In the case of a single card, the blister is sealed to the card using heat sealing. Alternatively, blisters can be trapped between front & back cards which are then bonded, or a card which is folded and then bonded. Front & back and fold-over cards can be bonded using heat or even cold sealing, a process which was invented by us.
Cold seal blister cards
Cold sealing saves energy and time during the sealing process. It means that blister cards can be sealed without using any heat. This is a great advantage because the only thing required to get a perfect bond is pressure. It makes the packing process simple, reliable, quick, environmentally friendly and most cost-effective.
Cold seal blister cards are printed only on one side of the cardboard. After assembly, all sides of the package, front and back – even the part behind the blister, can show your printed branding and instructions. This unique property allows the use of inexpensive cardboard. And with no heat required to seal the blister pack, cold seal cards are light on energy consumption. After use, the packaging materials – plastic and cardboard, can be taken apart and recycled separately, and therefore, in a totally environmentally friendly manner.
Heat seal blister cards
The most important feature of Ecobliss heat seal blister card technology is the high reliability and durability of the bond between blister and card, or card-to-card, in the case where a front & back blister card, or fold-over card is used. For the production of heat seal blister cards, Ecobliss uses its proven, environmentally friendly, water-based, Ecoseal 9000 series coating. Major clients such as Sony and P&G have tested and approved the heat seal cards produced by Ecobliss, and many millions of our blister cards are now hanging in stores across the globe.
