When we were given the task by a large paper manufacturer many years ago to test the implementation of grass cardboard and grass paper in the packaging sector, it was difficult to predict how quickly the market would accept this innovation.
Today these materials are a matter of course on the market.
Almost a year later, another manufacturer approached us to test paper with an extremely high proportion of denim residues.
This material is also finding its way onto the paper market.
A real innovation means the production of “paper” without cutting down a tree, without using water and without the use of chemicals, as is common in paper or cardboard production.
The so-called stone paper fulfills these properties.
The term “paper” is misleading because this substrate is not paper.
Stone substrate consists of 70-80% stone meal (calcium carbonate) and
20-30% made of HD-PE (binding agent).
The production of one ton of stone paper means the protection of 20 trees or the avoidance of approx. 72,740 liters of water, which would otherwise be used in the production of normal paper.
It forms a 100% barrier against water and therefore does not require any subsequent film lamination. The material is also flame retardant and very tear-resistant.
The proportion of 20-30% PE (based on natural gas or sugar cane) cannot be discussed away and must be considered in the same way in the environmental balance.
In terms of the long service life of this material, however, it offers an unbeatable advantage over the use of plastics. Stone paper is certified according to the Cradle to Cradle principle.
Once again, DMH’s know-how was in demand and we were commissioned to be one of the first companies to test this material in its application.
It is a matt substrate that has a pleasantly soft feel, reminiscent of thin plastic, is extremely tear-resistant and can carry several liters of water as a bag without softening.
And now you come into play!
We look forward to the feedback and suggestions from our customers about the use of these materials. Talk to us and let us consider what opportunities and areas of application this new innovative material can offer.
