Sappi Rockwell Solutions Starlid GPE-CL coated lidding film

Heat seal coating specialist Sappi Rockwell Solutions has developed a 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.

The 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% rPET trays.

Options for film include high-clarity anti-fog for optimised transparency and good oxygen and moisture vapour transmission rate barriers to increase product shelf life.

The film can seal to all types of food packaging trays, including PP, paperboard and all PET variants. It is suitable for all types of food products including dairy, convenience, meat, fruit and vegetables. Food-contact approved, it can be used for freezer, chiller, microwave and ovenable applications.
