Water-soluble bag for dry mortar

SolmixBag is a single-layer paper bag for storing and transporting dry building materials such as cement and dry mortar products. It is designed to dissolve when it comes into contact with water during the mixing process. the fibre of the packaging simply bonds with the product during mixing. This avoids waste, reduces the cost of disposing of paper waste and minimises dust on the construction site, as the bag is simply placed in the mixer without having to open it first.

The bag is produced in-house thanks to the company's integrated value chain: SolmixBag is made from Mondi's water-soluble sack kraft paper and is produced in-house.The new sack uses 20 per cent less paper than the industry-standard two-ply paper sacks. The solution can be filled on existing filling machines and is available in standard sizes, allowing customers a smooth transition from their existing solutions. SolmixBag offers the same strength and durability as its predecessors, with good printing results for a high-quality, outstanding appearance on the shelf.

Mondi has worked with its long-standing customer Baumit to bring SolmixBag for dry mortar to the market.

„We work closely with our partners in the building materials industry to minimise waste disposal and dust, which benefits both the environment and the workers on site. The launch of SolmixBag with Baumit is an important step in making a real difference to the sustainability of the industry as a whole.“

Ferdinand Muck, International Key Account Manager at Mondi 

Peter Weißmann, Head of R&D Dry Mix Mortar at Baumit says: „Thanks to the close co-operation with Mondi, we were able to thoroughly test and check these bags, and the results will soon benefit new product groups. The impact on sustainability is enormous. Our customers on construction sites love the new technology because of the many benefits - no waste and less dust are the two most important ones.“
