Domino Printing’s laser coding is ideal solution for compostable food packaging

July 7, 2022

A Cambridge company has created additive-free laser coding for food manufacturers using compostable cellulose films, helping them to achieve their sustainability goals and provide additional information for the consumer.

Domino Printing has collaborated with global packaging film producer, Futamura, on using laser coding for NatureFlex™, its compostable product used widely for food packaging.

Following initial testing, Domino’s D-Series CO2 laser was employed to code the NatureFlex compostable film and it achieved a clear, crisp, white code, even at fast printing speeds.

This offers manufacturers the option to use laser for simple codes such as best before dates and batch codes, as well as more complex designs and messaging, including graphics and scannable 2D codes.

The film is designed to meet all the global standards for industrial composting, including BS EN13432, and is certified as home compostable under the OK Compost Home standard.

Using laser coding on the NatureFlex flexible film means that no additional materials are added to the compostable substrate which could complicate final certification.

Dr Stefan Stadler, Team Leader at the Domino Laser Academy, said: “We are very pleased to be able to offer Futamura’s food packaging customers an additive-free laser coding solution for their product packaging.

“By taking a scientific approach to laser coding, we can significantly accelerate the process of consistently and reliably creating an attractive, high-contrast code, and ensure product safety and barrier properties are maintained – which is fundamental to our customers.”

Amaia Cowan, Business Development Manager – EMEA, Futamura UK added: “Brand owners are always looking at ways to communicate with their consumers on their packaging.

“All of our NatureFlex films are certified to prove their suitability for industrial and home composting. Many of our customers want to show the final packaging’s certification and additional disposal information on the film to help inform end consumers.”
