Heat seal packaging for economical, high-volume production
How cost-effective is heat seal packaging?
Heat and pressure
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. 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.
How theft secure is heat seal packaging?
Theft secure packaging makes it difficult, or even impossible for the consumer to open the packaging in the store without using scissors or a knife. In store theft is a big issue, and many retailers request producers to pack their expensive products in theft secure packaging. Ecobliss offers many material combinations to achieve the desired protection level. A full plastic, sealed blister (clamshell) with an insert card will always give the required protection level.
Heat Seal Packaging advantages overview

Production
- Less materials, therefore economical production
- Minimal setup scrap as there is only a single parameter (pressure)
- Suited for high volume packaging
- Full range of sealing equipment available, serving high volume demand

Environmental-friendly
- Highly recycled content cardboard can be used
- 100% Post-consumer recycled plastic can be used
- Plastic content can be reduced to a minimum
- Ecobliss coatings are water based
- Full and contamination free material separation when opening the packaging
- After opening, separate components can be recycled

Shelf presentation and consumer experience
- Optimised shelf presentation due to plastic content reduction
- Maximised communication area as the entire board surface can be printed
- Printing continues behind the product even though the card is printed single sided only
- Product visibility can be extended to the back side of the packaging
- Various easy opening possibilities
What is the difference between double carded and single card heat seal packaging?
Double carded packs clamp the blister cup between two cards; with a single card, the blister cup is sealed directly against the card. Both keep the use of materials to a minimum.
Is heat seal packaging suitable for high volumes?
Yes. Heat seal packaging suits high-volume, high-speed packaging, and a full range of sealing equipment is available for high volume demand.
Which materials can be used for heat seal packaging?
Ecobliss coatings are water based, and highly recycled content cardboard and 100% post-consumer recycled plastic can be used. Not all types of plastic are suitable for heat sealing, so the right type is chosen for each blister.
Do the materials separate after opening?
Yes. The materials separate fully and without contamination when the pack is opened, so the separate components can be recycled.
