Purina puts a great deal of thought and research into the type of bags their pet food goes into, Things like strength, durability, moisture control, and the ability to resist tearing are among the top priorities.and many factors are considered in this process.
Purina's material of choice to encompass all of these areas is polypropylene. Although many of their criteria are met by using it and plastic is technically recyclable, some recycling centers are not yet equipped to recycle polypropylene.
TLC, however, has been working to reduce the environmental impact, or “environmental pawprint”, since 2008.
As we await more companies getting on board with environmentally friendly and recyclable packaging, and more recycling centers accepting this material, most pet food bags are still considered a trash item.
