Sachet (4-Side Seal)
Four-side seal sachets are made from two separate sheets (or a folded sheet cut apart) that are sealed along all four edges. This creates a completely symmetrical package with consistent seal width on every side. The front and back panels can use different film stocks if needed, such as a clear front for product visibility and a foil-backed rear for barrier protection.
The four-side seal provides slightly higher seal integrity than three-side versions, which makes it a better choice for liquid and semi-liquid fills that put more stress on the seals.
