Most food pouches can withstand temperatures higher than the normal room temperature so you can easily place them outside a refrigerator. Generally speaking, all food items that do not spoil or rot without freezers can be kept at room temperature. Some items, on the other hand, need to be refrigerated. Frozen meat, for example, cannot be kept at room temperatures. If you store meat at room temperature for extended periods of time, the meat will soon go stale. Storage information is usually printed on food pouches so this is not really a cause for concern.
Some items like chocolates, ice cream, and frozen yogurt may not get spoiled at room temperature. Still, it is best to store them in a refrigerator because room temperature may make these food items un-consumable. Nobody likes melted ice cream, although technically it may not be unfit for consumption.
Stand up pouch packaging can tolerate temperatures higher than room temperature. This makes them suitable for packaging nearly all items. However, the food product packaged inside may require lower temperatures. In fact, some stand up bags used to package baby food can tolerate temperatures as high as 100 degree Celsius. You can heat these stand up pouches for food directly in a microwave oven.
While choosing standup bags for your product you need to consider the temperature at which the product is likely to be stored or used.
