Heatseal card-to-card blister packaging is the combination of a fold-over, orseparate front and back blister card and a transparent blister, bonded underheat and pressure. Together, blister and card form a beautiful, highly visibleshelf presentation of your product. To produce heat seal cards Ecobliss usestheir proven, environmentally friendly water-based Ecoseal 9000 series coating.This coating is applied to state-of-the art inline or offline equipment. Largecustomers such as Sony and P&G have tested and approved the heat seal cardsproduced by Ecobliss. Many millions of their blister cards are currentlyhanging on shelves around the globe.

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

Heatsealing of plastic-to-plastic (clamshell, printed blister, separate front andback blister) is done by bonding two parts of plastic together under theinfluence of heat and pressure. The package will pass through a patentedheating and cooling station to achieve a perfect seal. Sealing at the heatedstation is automatic and is controlled by a PLC seal timer. A cooling stationimmediately following the heated station, is used to flatten the package flangeand fuse the two pieces of plastic together.

Thissounds easy, but for successful heat sealing of plastic-to-plastic it is of theutmost importance that the right type of plastic is used for making theblisters. Not all types of plastic are suitable for heat sealing. So dependingon the design of the blisters, the tooling design is always a critical factorin getting the packaging process to run smoothly. Ecobliss is an expert in thisfield: both in the design and development of plastic-to-plastic blisters. Bothin the choice of packaging equipment and in the gearing-up of productiontooling.
Sellado HF/RF
Theadvantage of High Frequency sealing for blister packaging is the strength ofthe sealed flanges. Heat builds up evenly, in a very controlled way, from theinside of the plastic. The dosage of energy can then be set very accurately.High Frequency sealing is also called Radio Frequency sealing. HF/RF sealingcreates a bond that is equal or greater in strength than the material itself.The seal is consistent, nearly clear and uniform in appearance.
Theprinciple of High Frequency sealing is based on electro-magnetic heating ofnon-conducting materials such as plastics. During the sealing process, theplastic layers are joined under light pressure between electrodes that areconnected to a high frequency power generator. The molecules in the plasticsstart to vibrate. This vibration then heats the plastic up to a temperaturewhere the welding of the two layers takes place. The changing polarity of theHF waves passing through the plastic generates heat – just the right amount,very quickly. After the sealing cycle, the HF energy is shut off. Meanwhile theequipment holds the plastic sheets together for a very short time to cool underpressure.
