Reduce Plastic Consumption

with Thermoforming Technology

for Paper Board Pack Trays

Today plastic packs contribute 60 percent of the typical end user’s plastic waste. Worldwide around 325 million
tons of plastic are processed annually, of which some 80 million tons are used for producing plastic packs -
with Europe, Asia, and the USA among the largest producers. And plastics production continues to rise. It is
estimated that there will be a further doubling of worldwide plastics production in the coming two decades.

To implement sustainable packaging concepts in the food industry, are available in various grammages and with different functional layers.
