10. 1 Unit 10 Flexible Packaging In this unit we will learn about flexible packaging. This will include advantages compared to rigid packages, categories and types of flexible packages and their distinguishing features, and some of the trends in the flexible packaging market. 10. 1 Advantages of Flexible Packaging Throughout the history of packaging, there have been trends that alternate between rigid (bottles, cans, trays, etc.) and flexible (pouches, bags, etc.) packages. Both rigid and flexible packages have advantages and disadvantages for specific packaging applications, which need to be considered when choosing a packaging configuration. Here are some advantages of using flexible packaging: Lightweight : In general, the thin paper, plastic, or other material used to make a flexible package weighs less than the rigid packaging alternatives. This weight savings can be a significant advantage with distribution costs. Can you think of some products with rigid package forms that are also now available in flexible format? Economical : In general, lighter packaging saves on material costs. Flexible packaging can be easily adapted to a wide range of product weights and volumes, so it is easier to make a "family of products" with packaging made of the same materials, but with varied sizes and printing and other features. Versatile : Packaging can be manufactured to suit the particular needs of a particular product. There are many materials with a wide range of characteristics available and combination materials can be made by laminating or coextrusion. This makes it possible for flexible packaging to be used for food, beverages, pharmaceuticals, hardware, lawn and garden products, and more. Environmental : As discussed a bit in the previous unit, flexible packages have environmental benefits because they use less material and also take up less space in landfills. These advantages have been a driving force for the increased amount of flexibles that are showing up in stores. Comparison of rigid vs. flexible packaging for the same product.

10. 2 10.2 Categories of Flexible Packaging Flexible packaging can be divided into four general categories: wraps, sleeves, sacks and bags, and pouches. Wraps are formed from a flat piece of paper or film, which is “wrapped” around the material. In general, a wrap does not have a formed seam. If you put a side seam in a wrap but leave the ends open, it becomes a sleeve. If you seal one end, it becomes a sack or a bag. If you seal both ends, it will be, depending on the application, a sack, bag, or pouch. CSR Wrap which is used as a medical device packaging material. 10.1.1 Bags, Sacks, and Pouches The distinction between bags, sacks, and pouches is not always clear; the differences can often seem vague and arbitrary. One method of differentiating between them includes the following: Bags are made by suppliers (converters) and delivered to the packaging line ready to be filled and closed. There are many types, sizes, and styles of bags. Bags may be made of
