AUSTRIA – Sustainable packaging and paper manufacturer Mondi in collaboration with Baumit has rolled out a new water-soluble paper packaging solution called SolmixBag, for use in the global construction industry.

SolmixBag is a one-ply paper bag created to store and transport dry construction materials such as cement and dry mix mortar products.

It’s designed to dissolve when getting in contact with water during the mixing process – the fibre of the packaging simply integrates with the product as it is mixed.

This eliminates waste, reduces paper waste management costs and minimizes dust on the construction site, as the bag is simply placed into the mixer without the necessity to open it upfront.

Baumit Dry Mix Mortar research and development head Peter Weißmann said: “Working closely with Mondi means we have been able to test and trial these bags thoroughly and the results will soon benefit new product groups.

“Our customers on building sites love the new technology due to multiple benefits – no waste and reduced dust as the two most important.”

The bag is produced in-house thanks to the company’s uniquely integrated value chain: SolmixBag is created from Mondi’s water-soluble sack kraft paper and uses 20% less paper than the industry standard 2-ply paper bags.

The solution can run on existing filling machines, and it is available in standard sizes, offering customers a smooth transition from their existing solutions.

SolmixBag provides the same strength and shelf-life as its predecessors, with good printing results for a quality, stand-out appearance on shelf.

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

The two organizations collaborated closely throughout the product development and are committed to supporting the whole construction industry as it endeavors to reduce waste.

Mondi international key account manager Ferdinand Muck added: “We are closely collaborating with our partners in the building material industry to eliminate waste disposal and dust, which benefits both the environment and the workers on site.”

Meanwhile, Mondi has been offering sustainable packaging to other companies across the manufacturing industry.

In May this year, the company created a new paperbag solution called Protector Bag ExpandForm, which comes with an expandable feature to rollpack mattresses.

According to Mondi, Protector Bag ExpandForm replaces the plastic packaging that is currently used with a reusable and flexible alternative.

Made with Mondi’s Kraft paper, the paperbag packaging can be recycled, thus contributing to a circular economy. As it is made from renewable materials, the packaging is easy to dispose of and recycle in currently available paper waste streams.
