|Food Paper Packaging|
Wax-coated paper packages are the most preferred medium for bread packaging. Wax packaging has the capacity to soak in extra oil (Vanaspati), which helps in maintaining the overall look of the packaged loaf. Wax coated paper package is capable of maintaining moisture levels in bread, which results in better shelf life of the product as against other kinds of packaging. The moisture level is maintained by the ability of wax paper to breathe due to which wax paper loses moisture at a slow rate maintaining ideal moisture conditions required for maintaining the quality of food and at the same time avoiding bacterial/mould growth on the food contained. Infact with the use of right wax blend it is possible to engineer water vapor transmission rates to suit the products to be wrapped for example in compressed/fresh yeast wrappers and bread wrappers.
In the case of Sandwich Packaging where there is a requirement for high barrier properties towards moisture and grease, wax is coated on the paper side which is in direct contact with the food. The wax coating extends holding times (gives resistance to paper from getting soiled from grease/ moisture) making it a favorite wrap among fastfood restaurant chains. Also wax coating reduces UV light transmission that stops fatty products from becoming rancid. Aroma/odor barriers can be optimized by paper and wax coating technology. Depending on the chosen paper grammage, waxed paper is also very competitive on a linear meter basis. Needless to say, it is an ideal choice for sandwich wrappers.
