Other types of packaging
Wooden barrels have long been used to package a wide range of liquid foods such as wine, cooking oils, juices and beer. Flavor compounds from the wood improve the quality of the products. Glass bottles and jars still offer advantages over other materials, though they are being increasingly displaced by plastics for packaging condiments and oils. They are still widely used for beer, juices, jams and jellies, and pickles. Paper of different types still finds use as a packaging material for sacks of flour, sugar, and some fruits and vegetables.
