Cellophane and polypropylene clear plastic bags are most commonly used for packaging food since they are made from strong materials and allows clarity of the products inside.
Cellophane is easy to manipulate and is great for products that need to breath, such as produce or potpourri, since the material has high permeability to moisture. Vapor permeability (or breathability) is a material’s ability to allow water “vapor” to pass. Preventing moisture from building up will keep the product fresher longer.
Polypropylene is used in the food industry as well because of its ability to prevent evaporation or exposure to bacteria. It is also used for storage and other product packaging such as for gift baskets because the material is crystal clear, allowing the consumer to see the product but still giving it the protection it needs with the hard-to-tear material.
