British flexible packaging company Parkside has announced the launch of its new range of sustainable lidding films to address the packaging sustainability challenges facing the country.

The lidding film range comprises certified renewable and compostable films, paper-based solutions, as well as recyclable monomers.

It has been launched as part of the company’s ‘Sustainable 7’ product strategy.

The new range, according to Parkside, is augmented by its in-house laser scoring technology, called ParkScribe.

ParkScribe technology helps in the production of easy peel-and-reseal polyethylene terephthalate lids, and is an integral component of packaging, ensuring that the film remains attached to the pack throughout the recycling process.

Parkside head of Technical Joshua Swann said: “ParkScribe uses a laser to score substrates quickly and with micron-level precision.

“It means we can cut through only a few layers of the lidding material in specific areas to create a lid that peels away, then reseals without the need for additional glue strips, zips, or stickers which can affect recyclability.

“When weld sealed to a tray it is fully recyclable under current OPRL [UK recycling scheme] guidelines provided the polymer is the same as the one used in the tray, while still being easy to open and reseal to meet consumer demands for convenience.”

The company said its home and industrially compostable duplex laminate films can be used throughout the supply chain for various food applications and they become fully compostable when used with pulp trays.

Parkside also has an extended range of sustainable films that help in delivering higher levels of oxygen or moisture protection for food items such as chilled meats, dairy products and soft fruits.

Swann added: “This is just one demonstration of the innovation present in our lidding film range.

“Our latest range of recyclable plastic, 30%-plus recycled content, paper-based, and compostable films enables customers to be flexible when developing packaging that perfectly suits the needs of their application.”
