Coveris takes a stand against waste with mono-material packaging
Coveris has introduced mono-material packaging for tortilla wraps as part of its No Waste commitment.
With a lengthy shelf life, MonoFlex Thermoform film packaging takes the place of thermoforming substrates made of mixed materials that are not recyclable.
The project resulted from close cooperation with a tortilla wrap manufacturer, seeking a more sustainable alternative to the previously used PA/PE structure.
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 extensive performance testing at Coveris’ Food Science Lab in Gainsborough, UK, the team opted for a mono-material based top and base thermoforming film. This material successfully protected the sensitive tortilla wraps against mould throughout the required testing period while enabling recycling in the same waste stream.
The packaging solution offers several key benefits, including advanced barrier properties for extended product protection and shelf-life, as well as strong puncture resistance. Additionally, MonoFlex Thermoform allows a seamless switch on the packing lines from alternative substrates, maintaining compatibility with existing packing lines without compromising packaging speeds.
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 tactile lacquer finishing, enhancing consumer appeal and producing an attractive on-shelf presentation.
Katja Killian, BU flexibles business development director at Coveris noted the success of the commercial launch of MonoFlexThermoform for tortilla wraps.
He is particularly pleased that the 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”, Killian said.
