It is a type of plastic bag but sometimes also has plastic bottle characteristics. Daypacks are commonly used for powders or ready-to-drink beverages. The bottom part of a stand-up bag is gusseted to provide support for display or use.stand up bag

2. What is flat bottom bag

 Flat-bottom bag is a five-sided, free-standing pouch with a flat, rectangular base. It has material for greater space and strength, known as gussets, on both the left and right side of the pouch, with a fastener on top.

Most flat bottom bags are made with multiple layers to protect against external factors such as light, oxygen, moisture, and heat.
