Stanelco says the "Perfect Sealing" technology, retrofittable for around £40,000 per machine or incorporated on a purpose-designed RF sealer, offers major environmental and cost-saving benefits. By eliminating the sealing layers and specialist sealing coatings conversion off-cuts can, for the first time, be "recycled" back into the tray manufacturing process. By reusing such scrap, savings of "at least 20%" can reportedly be achieved, while removal of a PE layer enables used trays to be cost-effectively recycled after use. In addition, the RF process provides potential energy savings of up to 50% since the sealing head needs simply to be switched on, with no pre-heating time.
"Total adoption of this technology UK-wide would cut the volume of a plastic going to landfill ever year by 10,000 tonnes," says Stanelco ceo Ian Balchin.
