Most of the product that goes into the containers have already been pasteurized by the time the product is being filled. Hot filling is a popular pasteurization process, particularly for acidic beverages and foods (pH of less than 4.6) that need to be shelf stable at ambient temperatures. The heated product is filled into the container which is usually glass or PET plastic. A label material we use often for these types of products is white pearlescent polypropylene, a semi-conformable film. Often, high-pressure processing is used in place of heat pasteurization for juices and we also have labels that can be used with this process, such as white BOPP film with UV gloss lamination which has excellent moisture resistance.
