Yes, they are.

Paper labels were the common norm in the ‘60s and ‘70s. They were pasted onto packaging mediums, chiefly plastic bottles and cardboard boxes. This practice lasted until the late ‘70s and ‘80s, when companies increasingly started using self adhesive labels. This trend caught on like wildfire. In the ‘90s, companies started looking for new labels that did not look like same old boring labels, provided better surfaces, and were compatible with a variety of surfaces. That was the birth of non-paper labels, which were made of a plastic material. Today, non-paper labels account for a large portion of product labeling which is used on a variety of packaging mediums, including stand up pouches.

Stand up pouch bags are print friendly for two primary reasons:

(1) They provide a better surface for non-paper labels because the materials used in the production of both are similar.

(2) Their broad backs and wide fronts offer print friendly surface areas. Plastic bottles and many other packaging materials are cylindrical in shape. This makes it difficult for designers to produce an artwork which will be visible to consumers without the need to rotate them. There is no such difficulty with pouch bags.

Given so many options, standup bags are certainly a print friendly packaging option.
