COVERIS has introduced a mono-material packaging solution for tortilla wraps.
Supporting the firm’s No Waste mission, MonoFlex Thermoform film packaging is designed to replace non-recyclable, mixed material thermoforming substrates.
The project resulted from cooperation with a tortilla wrap manufacturer, seeking a more sustainable alternative to the previously used PA/PE structure. Coveris explained the primary challenge was identifying a recyclable material while ensuring a minimum six-month shelf-life for a tortilla with low quantity of preservatives.
Following performance testing at Coveris’ Food Science Lab in Gainsborough, the team opted for a mono-material based top and base thermoforming film. This material is said to have protected the tortilla wraps against mould throughout the required testing period while enabling recycling in the same waste stream.
Coveris added that the solution offers benefits including advanced barrier properties for extended product protection and shelf-life, as well as strong puncture resistance. MonoFlex Thermoform also allows a ‘seamless’ switch on the packing lines from alternative substrates, maintaining compatibility with existing packing lines.
Available as fully printed or unprinted top and base film, the packaging supports conventional and HD flexographic or rotogravure print with options for matt, gloss and lacquer finishing.
Katja Killian, BU flexibles business development director at Coveris, said, “We are extremely pleased with the successful commercial launch of MonoFlexThermoform for tortilla wraps. This sustainable alternative to non-recyclable materials delivers the same shelf-life performance while saving resources and helping customers meet their sustainability targets.
“It also showcases the advantage of collaboration between Coveris’ production sites and Film Science Lab expertise, enabling the development of high-performance sustainable packaging solutions.”
