Let's now look at each of the above criteria for best dog food packaging, and see if stand up bags fulfill these criteria:
(1) Protection from environmental factors
Humidity, air, dirt, bacteria, and other kinds of factors in the environment can react with dog food and make it go stale before its sell-by date. Stand up pouches are made from several polymer and food grade layers. Together these layers provide ample protection from environmental factors that can degrade your dog food.
(2) Contaminant free
StandUpPouches.net's custom printed stand up bags are made from FDA (Food and Drug Administration) approved food grade material. The federal agency has approved our packaging materials by granting us the status of being safe for food materials.
(3) Physical factors
Several layers of polymer and food grade material provide sufficient protection against punctures which may occur during transportation and handling of food. Together these layers are sufficiently thick to bear small shocks.
(4) User friendliness
Stand up pouches can be made very user friendly with the addition of accessories such as a spout or a zip lock. An additional feature of these packages is that your dog can eat directly from them. An unevenly opened tin can might hurt the mouth of your dog, but stand up pouches pose no such danger to dogs.
(5) Advertisement
Children learn during school that a sphere has the lowest surface area for a given volume. In everyday language, the rounder an object is, the lesser surface area it has. Thus for the same volume, an expensive jar or a tin can provide a lesser surface area for advertising than a stand up pouch. A stand up bag provides more surface area which can be used for logo placement, brand building, and product information.
Given all these factors, it is safe to assume that standup bags are the best packaging option for dog food and treats.
