has purchased two production lines from SML to boost its North American capacity for high-end stretch film. Scheduled for delivery in the second and third quarters of 2023, one will be installed in a new wing of Sigma’s Belleville, Ontario plant, while the other will replace a legacy line in Tulsa, OK.
The two nine-layer lines will significantly increase capacity at their respective locations. They have also been configured for maximum flexibility to allow rapid product changes to meet local demands.
Sigma has also recently added capacity with new SML lines at its stretch film plants in Riverside, Calif. and Shelbyville, Ken.
