Heat sealing

Beautiful, highly visible shelf presentation


Heat seal card-to-card blister packaging is the combination of a fold-over, or separate front and back blister card and a transparent blister, bonded under heat and pressure. Together, blister and card form a beautiful, highly visible shelf presentation of your product. For the production of heat seal cards Ecobliss uses their proven, environmentally friendly water-based Ecoseal 9000 series coating. This coating is applied on state-of-the art inline or offline equipment. Large customers such as Sony and P&G have tested and approved the heat seal cards produced by Ecobliss and many millions of their blister cards are hanging on shelves around in the globe.


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.


Heat sealing of plastic-to-plastic (clamshell, printed blister, separate front and back blister) is done by bonding two parts of plastic together under the influence of heat and pressure. The package will pass through a patented heating and cooling station in order to achieve a perfect seal. Sealing at the heated station is automatic and is controlled by a PLC seal timer. A cooling station immediately following the the heated station, is used to flatten the package flange and fuse the two pieces of plastic together.

Expert in this field

This sounds easy, but for successful heat sealing of plastic-to-plastic it is of the utmost importance that the right type of plastic is used for making the blisters. Not all types of plastic are suitable for heat sealing, and depending on the design of the blisters, the tooling design is always a critical factor in getting the packaging process to run smoothly. Ecobliss is an expert in this field: both in the design and development of plastic-to-plastic blisters, in the choice of packaging equipment and in the gearing-up of production tooling.
