Par-Pak Ltd. has launched a new coextrusion line that moves the company into the production of amorphous PET sheet for packaging.
The Brampton, Ontario, company installed its first line dedicated to APET production this summer, the second extrusion line at Par-Pak, said Amin Sajun, Par-Pak vice president of operations, in a Sept. 22 telephone interview. Par-Pak officials discussed the expansion at the Society of Plastics Engineers' 2003 Thermoforming Conference in Cincinnati.
Par-Pak thermoforms rigid plastic containers, running 75 machines at its four facilities. In 1999, the company entered sheet extrusion, making biaxially oriented polystyrene sheet in Brampton, Sajun said. The line has a capacity in excess of 40 million pounds a year of BOPS sheet.
The BOPS sheet is ideal for bakery and deli containers, but the new APET material is better-suited than BOPS for low-temperature applications, including the freezing of bakery and deli products in thermoformed packages, according to Sajun.
APET sheet is used in such products as food containers and consumer clamshell and blister packaging.
The new Davis-Standard machine can make coextruded or monolayer sheet or run the material side-by-side in clear and black on the same line, Sajun said. The APET line has the capacity to process about 25 million to 30 million pounds a year, he said.
``A lot of companies are working with PET sheet, but very few are performing coextrusion or side-by-side extrusion,'' Sajun said.
The company has about 400 employees at its 325,000-square-foot Brampton facility.
