Tri-extrusion heightens Haremar's capability (sidebar)

Film wraps McDonald’s Canadian buns

One of Haremar’s key customers is privately held Sons Bakery, Brampton, Ontario, Canada, which has supplied hamburger buns to McDonald’s restaurants in Ontario since 1984. The buns are packed in a 6x5 pattern using clear, unprinted film from Haremar. Sons refers to the 30-count packs as “pillows.”

After overwrapping, one or two pillows are loaded into reusable plastic trays that are shipped directly to more than 300 McDonald’s restaurants.

With its newfound tri-extrusion upgrade, Haremar switched Sons in August from a ½-mil monolayer film that was a linear low-density polyethylene/LDPE blend to a superior three-layer ½-mil film, says Haremar’s Mark Lichtblau. The new film comprises three identically thick layers of a blend of LLDPE/LDPE using resins from Dow Chemical, according to Lichtblau. He says that all three layers are “LLDPE-rich.” Haremar was able to maintain film costs for Sons because the improved line efficiencies offset added resin costs.
