It was not uncommon to find sugar, flour, and other everyday products in hessian sacks. These sacks were just sitting ducks against atmospheric moisture and minute dirt particles. The multiple layer structure of stand up pouch bags provides much better protection against both moisture and tiny dust particles.
The dairy industry is a shining example of the high standards of hygienic food packaging that are attainable with stand up bags. Made from high quality FDA approved materials, stand up pouches keep milk products well protected until opened by the consumer.
Large and small cheese sellers in the United States prefer stand up pouches to older packaging mediums because of their non toxic nature and better security. Dairy products stored in standup pouches last longer. Plastics are chemically inert. This means they do not react with food products, which enhances the safety of the pouches. And above all, stand up pouches are economical in many ways. They are a creative food packaging method which is cheaper than older methods such as hessian sacks.
