Three Side Seal Round PVC Shrink Pouch

Three-side seal round PVC shrink pouches (also known as round bottom or arc-shaped shrink bags) are specialized packaging solutions designed with a curved or semi-circular seal at one end. Unlike standard rectangular pouches, the rounded bottom allows the film to conform smoothly to the contours of circular or irregular items without leaving the "ears" (excess pointed film) that typically occur at the corners of a flat bag after shrinking.
