Accelerate production with Heat-free Sealing
Our specialised Baro-seal film layers match the strength of heat-sealing without any heating!
Regular heat-seal
Up to 3x speed!
Baro-seal
50 billion kg
Flexible plastics produced each year.
The fastest-growing packaging category.
~50% of UK rigid plastics are recycled.
Only 5%
for flexibles.
>40% of flexible plastic is un-recyclable multi-material plastic films
50% of plastics
are single-use.
2.5 billion
sachets used every day.
What solutions are there?
Paper-based
60% global recycling rate
Can currently displace 15% of flexibles
Plastic coatings for sealing and barrier
Mono-material plastics
One polymer type (e.g. LDPE, PP)
Can be effectively separated and recycled
Avoids PPWR and EPR taxes
One unavoidable issue. Heat-sealing.
“It is hard to melt the sealant through insulating paper”
“Mono-material films have a narrow heating window”
Regular heat-seal
Melts at ~120 °C, but heat must penetrate THROUGH the substrate, which can take several seconds.
Multi-materials: delay can be reduced by increasing the pressing temperature to ~200 °C.
HOWEVER:
Paper-based: thick, thermally insulating, and damaged by high temperatures.
Mono-materials: temperature limited to slightly above the heat-seal temperature.
AS A RESULT, heat-sealing of paper-based and mono-material flexibles is CHALLENGING and SLOW.
~1.5 s per seal
Baro-seal
Baro-seal layer melts at room temperature, with only pressure
Compatible with existing sealing equipment
Matches heat-seal strength: Suitable for solid, gel, and liquid products
Up to 3x the sealing-speed of heat-seal!
Tuneable biodegradation for compostable paper-based applications
~0.5 s per seal
