This plant is usually harmless to humans because the humans’ ability to smell is not as sharp as is found in cats. The plant may even fail to trigger a reaction in cats if it has lost its odor. Therefore the most important quality businesses are looking for their packaging is that it preserves the odor. Stand up bags are perfect for the task. Their multiple layered structure keeps odors in, thus keeping catnip effective.
Consumers can also use pouch bags with zippers. This allows them to use a part of packaged catnip and preserve the remaining for future use. Manufacturers can add more accessories to these flexible pouches to make them more capable of carrying catnip in full potency to consumers. Therefore much of the catnip we see around is packaged in stand up pouches.
