As part of its No Waste mission, Coveris has launched a monomaterial packaging solution for tortilla wraps. MonoFlex Thermoform film packaging replaces non-recyclable, mixed-material thermoforming substrates while maintaining a long shelf life.

The project resulted from close cooperation with a tortilla wrap manufacturer that was 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 a low quantity of preservatives. 

Following extensive performance testing at Coveris’ Food Science Lab in Gainsborough, UK, the team opted for a monomaterial-based top and base thermoforming film. This material successfully protected the sensitive tortilla wraps against mold 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 matte, gloss, and tactile lacquer finishing, enhancing consumer appeal and producing an attractive on-shelf presentation.
