Accordion bags, also known as gusseted bags or side‑accordion bags, feature expandable accordion folds on both sides of the bag body, allowing the bag to widen laterally and increase its capacity. When empty, the folds collapse inward, flattening the bag to save space; once filled, the sides unfold, dramatically boosting the bag’s volume. These bags can be configured with various sealing styles, including three‑side seal, four‑side seal, and back seal, and are available in two formats: pre‑formed pouches and roll stock.

Product Description

Accordion bags, also known as gusseted bags or side‑accordion bags, feature expandable accordion folds on both sides of the bag body, allowing the bag to widen laterally for increased capacity. When empty, the folds collapse inward, keeping the bag flat and space‑efficient; once filled, the sides unfold, dramatically boosting the bag’s volume. These bags can be configured with various sealing styles, including three‑side seal, four‑side seal, and back seal, and are available in two formats: pre‑made pouches and roll stock.

The bag features accordion-style pleats on both sides, forming a retractable structure. When empty, the pleats fold flat against the bag body, resulting in a compact, flattened profile; once filled with product, the pleats expand outward, increasing the bag’s width and significantly boosting its capacity. Based on the sealing configuration, these bags can be categorized as three-side-seal accordion bags, four-side-seal accordion bags, or back-seal accordion bags; when paired with various bottom designs, some styles can achieve simple self‑standing functionality.

Optional Process Features

Easy-tear notch, serrated edge, hanging hole, composite zipper, partial window, matte frosted finish; can be manufactured as a boil‑in‑bag with an accordion‑style design.
