A pillow pouch is a simple, flexible packaging solution commonly used for snacks, candies, and other lightweight products. Shaped like a pillow, it features seals on the top and bottom, with a vertical seal running along the back. This design offers a cost-effective and easy-to-produce option for packaging, while still providing good barrier protection against moisture, air, and contaminants. The pillow pouch is lightweight and compact, making it ideal for efficient storage and shipping. It's a popular choice for single-serve or portioned products due to its simplicity and functionality.
