This is an interesting question. You can store gas as well as solid products in stand up bags but – and this is a big “but” – they is not at all an efficient method to store gases. Gas is usually stored in metal cylinders which are made to bear gas pressure equivalent to several atmospheres. It allows them to carry several times more gas than what can be stored under one atmospheric pressure. To compare, a stand up bag is essentially a plastic pouch which is not sufficiently strong to carry gas efficiently.

The situation reverses when it comes to packaging solid products. Here, stand up pouches offer several advantages. They are sufficiently strong to carry products of everyday use. Unlike cylinders they are inexpensive to produce. Their storage and transport costs are minimal, as compared to other packaging methods. Accessories like hang-holes, zippers, and spouts make their storage and use even easier. StandUpPouches.net's pouches are made from FDA (Food and Drug Administration) approved food grade material. This material has been tested safe and contaminant free to store solid and liquid food products.

To conclude, even though stand up bags are not an efficient method to store gas, they are an excellent method to store solid and liquid food and non-food products of various kinds.
