Types and Sizes of Packages for Fluid Milk Products Fluid milk products are packaged for distribution in refillable glass bottles, single-service paper cartons and refillable metal cans. By size, consumer packages range from one-half pint to one gallon for glass bottles and from one-half pint to one-half gallon for paper cartons. The standard size metal dispenser can is five gallons. A total of ten types and sizes were available for packaging fluid milk products (Table 27). With a minimum of ten fluid milk products commonly distrib- uted by dairy firms, the product mix could include 100 combinations of product, package type and size of container. Since many firms distribute two, three or even four types of fresh whole milk, two types of fluid skim milk and buttermilk, numerous non-fluid dairy products and other non-dairy items, it is not uncommon for a firm's product mix to run as high as 130 to 140 items.
