This heat seal blister technology consists simply of a single piece of board and a blister, and is therefore very economical to produce. The board is coated with a layer of our proven, environmentally friendly, water-based HS9000 series seal coating. After adding a product, the blister can be bonded directly to one side of the card using heat and pressure. Depending on the market in which they are used, the blisters are typically made of PET or PVC. A range from very simple to highly automated heat seal blister packaging equipment is available to support the packaging process.
