Packaging and storage
Snack foods which are sold for immediate consumption have no need for packaging. For a longer shelf-life the package should provide a barrier to moisture to avoid the product losing its crispness, and to oil, air, and light. As many fried foods are also fragile, the pack should help prevent crushing.For long-term storage, paper is of no use for this type of product. Polythene, while being a good barrier to moisture and oil seepage, is not a good barrier to light or air. Polypropylene is a better alternative although it is often more expensive.
The following tables outline the production and equipment needed for a selected range of snack foods:
