A new kind of packaging is taking the food and beverage industry by storm: plastic pouches with screw-off caps. Some people consider these pouches the greatest thing since PET bottles, the plastic bottles commonly used for mineral water and other beverages. The pouches have actually been used for a while now, mainly as containers for jelly-type health drinks. What is new, though, is the wide array of foods and drinks now being sold in plastic pouches. Lately the variety has expanded to include yogurt, ice cream, salad dressing, and even alcoholic beverages. A growing number of people, mainly young people, are discovering the convenience of taking a meal or snack on the go by squeezing it from a plastic pouch directly into one's mouth.
