Food and Drink in Screw-Cap Pouches Let People Refuel on the Go (September 20, 2005)


Even Housewives Can't Resist the PouchOne of the advantages of the pouch as a food container is that it gets smaller as the product is used up, making it possible to save space in the refrigerator. Ebara Foods Industry Co., a salad dressing manufacturer that packages its products mainly in bottles, has adopted the screw-cap pouch for a new dressing. The pouch is an ideal container for the dressing, which has a jellylike texture. The dressing is popular among housewives because it keeps salad vegetables crisp and because it can be used as a filler medium for canapés.
Demand for food and beverages packaged in screw-cap pouches is growing. According to an estimate by one company that makes the plastic film used for the pouches, one billion pouches of food and drink will be manufactured in 2005. Though estimates may vary, this "super fast food" packaging, made to order for hectic modern-day life, will almost certainly continue to find an ever-wider array of uses.

Full of fat
Full of the "wrong" kind of oil (canola, etc.)
Full of sugar
Full of salt
Full of suspect preservatives and chemicals
