Out of all the questions that our clients ask us, this is among the most frequently asked ones. The quantity that can be packaged in a particular stand up pouch would primarily depend on the nature of the product– whether it’s a solid, liquid, or semi-solid substance. For example, the dimensions of pouches used for packing the same weight of fruit would vary depending on the content – it could be the actual fruit, its pulp, or juice.
To get a rough idea of the variations, you could say that a 3 x 5 x 2 pouch works well for an ounce of dry produce and 3 ounces of a liquid. Similarly, a standup bag with dimensions of 7 x 11 x 3.5 pouch will comfortably store 32 ounces of a wet or liquid product but only 12 ounces of a dry item.
Apart from the nature of the product, the quantity that can be stored also depends on the packaging method. If the product is such that once the packet is opened, it’ll be consumed fully (like a bar of chocolate), the packaging can be tight and there’s no need to keep any extra space at the top. However, if the consumer is likely to use the contents in small quantities, as in the case of stand up food pouches, the contents would need to be loosely packed with sufficient space at the top to be able to reach inside. A zip lock too might be needed. So multiple factors need to be kept in mind when making capacity calculations.
