Film equipment supplier Macro Engineering & Technology Inc. has developed a DXL series of double-bubble lines to make barrier shrink bag film.
The primary products for DXL machines are five-layer and seven-layer tubing for shrink bags used as food packaging for cheeses and fresh or smoked meats. The barrier layer can be nylon, polyvinylidene chloride or ethylene vinyl alcohol.
The shrink bag film has a barrier against water, oxygen and aromas, shrinkage of 40-60 percent, and superior puncture resistance, Macro Engineering said. The bags also are heat-sealable and printable.
Macro is based in Mississauga, Ontario.
