Heat seal coating specialist, Sappi Rockwell Solutions has developed its first sustainable, multi-substrate, heat sealing lidding film. Developed and manufactured in house, Starlid GPE-CL is an extrusion coated lidding film specifically formulated and processed on Sappi Rockwell’s solvent-free coating line. It is designed to outperform all other lidding films.

Importantly, the Starlid GPE-CL coating can be applied onto any film including those with post-consumer recycled (PCR) content. The company currently coats up to 60% PCR film, which is compatible with all tray types, including 100% rPETtrays.

Options for Starlid GPE-CL include Sappi Rockwell’s high-clarity anti-fog for optimized transparency and good oxygen and moisture vapor transmission rate barriers to increase product shelf-life.

Moreover, the Starlid GPE-CL seals to all types of food packaging trays, including PP, paperboard and all PET variants. This enables manufacturers and brand owners to move away from using multiple film types for different product requirements and into a true mono layer lidding material suitable for all tray types.

Starlid GPE-CL supports eco-friendly packaging

Chris Button, head of Sales at Sappi Rockwell Solutions, explained, “We are committed to helping our customers reduce their impact on the environment through the development of innovative and sustainable packaging solutions.

Starlid GPE-CL will help customers reduce their environmental impact and bring them in line with the UK plastic packaging levy scheduled for April 2022. Using one lidding material for all tray types delivers cost saving opportunities, improves operational efficiencies, and significantly reduces both plastic usage and waste.

Starlid GPE-CL provides a strong, peelable seal on all types of tray materials, including paperboard trays which is one of the most rapidly expanding sustainability trends in the food industry today,” Chris continued. “As eco-friendly packaging becomes a higher priority with both brands and consumers, Starlid GPE-CL is a significant development for the food packaging industry.”

Suitable for all types of food products including dairy, convenience, meat, fruit and vegetables. Starlid GPE-CL is food contact approved and can be used for freezer, chiller, microwave and ovenable applications.

With over 35 years of experience Sappi Rockwell Solutions is a well-established business based in Dundee, Scotland and focused on developing unique and proprietary coating formulations to manufacture highly specialized packaging films. Acquired by Sappi Global in 2017, Sappi Rockwell Solutions is a subsidiary of Sappi Europe.

The Covid-19 pandemic led to the country-wide lockdown on 25 March 2020. It will be two years tomorrow as I write this. What have we learned in this time? Maybe the meaning of resilience since small companies like us have had to rely on our resources and the forbearance of our employees as we have struggled to produce our trade platforms.

The print and packaging industries have been fortunate, although the commercial printing industry is still to recover. We have learned more about the digital transformation that affects commercial printing and packaging. Ultimately digital will help print grow in a country where we are still far behind in our paper and print consumption and where digital is a leapfrog technology that will only increase the demand for print in the foreseeable future.

Web analytics show that we now have readership in North America and Europe amongst the 90 countries where our five platforms reach. Our traffic which more than doubled in 2020, has at times gone up by another 50% in 2021. And advertising which had fallen to pieces in 2020 and 2021, has started its return since January 2022.

As the economy approaches real growth with unevenness and shortages a given, we are looking forward to the PrintPack India exhibition in Greater Noida. We are again appointed to produce the Show Daily on all five days of the show from 26 to 30 May 2022.

It is the right time to support our high-impact reporting and authoritative and technical information with some of the best correspondents in the industry. Readers can power Packaging South Asia’s balanced industry journalism and help sustain us by subscribing.
