The four primary goals of packaging-product protection, identification, dispensing and merchandising-won't change in the 21st century. But as we near that milestone, the market forces that more subtly affect packaging are evolving.
To give consumers a sealed and reclosable bag, candy and snack maker Golden Stream adds new compact zipper applicator onto an existing form/fill/seal line. Savings vs preapplied bags and an option to run nonzipper webs keeps company as flexible as its packaging.
Ilapak's (Newtown, PA) Cougar(TM)LS flowrapper now has a lap seal feature for use on shrink, PE and other films. Uses a rotary hot knife to form end seals, eliminating hot wires and producing attractive bead seals.
The Muller® 2201 semi-automatic stretch wrapper coupled with the patented Pak-Air carriage from Newtec (Sunset Hills, MO) provides an economical alternative for pallet stretch wrapping of fresh produce and other products that must "breathe." Using ordinary stretch film instead of netting or costly macro-perforated film, the Pak-Air automatically pre-stretches and slices the film into bands.
A multimillion-dollar five-year contract was signed last month by Mobil Corp., Fairfax, VA, that gives Continental Plastic Containers (Norwalk, CT) an unusual management responsibility for Mobil's plastic packaging for motor oils.
Spectratech® white concentrates for use in cast and blown film and extrusion coating from Quantum Chemical (Cincinnati, OH) allow processors to cut material costs and achieve improved processing characteristics.
HICOR(TM) OHD is a one-side sealable oriented HDPE film from Mobil Chemical Films Div. (Pittsford, NY). It has good deadfold and directional tear characteristics and is suitable for use as an inner wrap in boxes of crackers, snacks and cereals.
