WeighPack Systems (Montreal, Quebec, Canada) offers machines for efficient and accurate bagging of fresh, processed or frozen foods from less than 1/2 oz to 50 lb into a variety of bags, cartons, jars or trays.
Green-Tek (Edgerton, WI) has developed dual-ovenable, micro-waveable and freezer compatible trays made of CPET. These thermally stable trays can withstand 40° to 400°F and are available in black or white.
Clear OPS tubs for baked goods from Wilkinson Mfg. (Ft. Calhoun, NE) use the patented DeltaPak(TM) TE closure for protection against pilferage. Overwrap or shrink bands can be eliminated and the tubs can be opened easily in a simple, one-step process.
HiPERTUF(TM) polyester resins from Shell Chemical (Akron, OH) are homopolymer 2ƾ dimethyl naphthalate-based polyethylene naphthalate (PEN), which provide a number of benefits over PET, including hotter fill temperatures, better chemical resistance, and improved gas and UV barriers.
Packagers worrying about the availability of recycled polyethylene terephthalate resin will likely be encouraged by the announcement last month that a new process for recycling post-consumer PET has been developed by United Resource Recovery Corp.
