Barrier films protect packaged products from:
1) Moisture exchange which can cause drying out or spoilage of hygroscopic products like bakery items and milk powder.
2) Oxygen permeation which can lead to microbiological spoilage through oxidation of flavors and oils in products like bakery items and ready meals.
3) Emerging carbon dioxide and changes in protective gas types which can affect products and potentially cause undesired vacuums in bakery items and meat products.
4) Aroma exchange which can result in aroma loss or taking on different smells in packaged items such as coffee, spices and cleaning agents.

1. Barrier films protect against Exchange of moisture- Protection against drying up (e.g., bakery products)- Protection of hygroscopic products (e.g., milk powder) Oxygen permeation- microbiologic spoilage (oxidation of greases, flavors, etc e.g., bakery products, nut products, ready-to-serve meals) Emerging of CO2- change of protective gas type- undesired vacuum effect (e.g., with bakery products, meat products) Exchange of aroma- loss of aroma from the product packaged- assuming a different smell (e.g., coffee, spices, washing agents)
