SOS bags or self-opening bags are paper bags with a square bottom and side gussets. They are named self-opening because they open on their own when full of product. SOS bags are often used for packaging smaller items such as jewelry, clothing, and gifts.
In most cases, SOS bags are used for takeaway purposes and are commonly found in coffee shops and bakeries. For a more natural appearance, these bags are constructed of brown kraft paper. However, you can also find them in other colors, such as black and white.
