NEWS: Water-Soluble Film for Single-Dose Packs Can Reach New Markets


Mondi’s technical films business has created and introduced a water soluble film for the smart and convenient packing and dosing of powders, tabs and granulates. Dissolving completely in water, the film is ideal for single doses of dry materials, such as dishwasher and laundry tabs or bath salts.

The film offers excellent sealing and deep drawing properties, provides an effective barrier to oxygen and is completely soluble even in cold water, says the company. Consumers are also protected from direct contact with the contents, which adds an extra layer of safety.

Customers can bolster their sustainable credentials too, according to Mondi, through the environmental benefits water soluble films provide compared to standard plastic films. In addition to reducing overall packaging waste, the films are also considered to be biodegradable, non-toxic and non-inhibitory.

Oliver Sperber, chief innovation officer at Mondi Consumer Packaging, commented, “Mondi’s water soluble film provides several layers of benefits for both brands and their customers. Our application engineers are able to customize the film according to customers’ specific needs as well as on-site support to successfully launch a product using this material. Interplay between central and local R&D and Innovation teams, in partnership with our customers, is key to this.”

One such collaboration enabled the development of flow pack film tabs for dishwashing applications.

While Mondi’s water soluble films are particularly suited to the home and personal care market, a number of applications in other sectors are continuing to emerge. Agrochemical packaging, for fertilizer, sowing and disinfectants, for example, is a major area of interest, as is the building and construction sector – where the films can be used as liner for bags in the cement industry.
