The jute sacks that are used for pet food packaging have to go through a lot of manufacturing processes in order to be able to withstand the weight and contents of the pet food. The first step is to weave the jute fabric into a sack. The next step is to treat the jute fabric with a resin in order to make it waterproof. After that, the jute sack is printed with the designs and logos of the pet food company. Finally, the jute sack is sewn and stitched together.
