Three-Side Seal Pouch Packaging
Three-side seal pouches are economical preformed flexible packages with a simple flat structure, reliable seals and extensive customization options. They are widely used for food, personal care, pharmaceutical, electronic and industrial products.
What Is Three-Side Seal Pouch Packaging?
A three-side seal pouch is a preformed flat pouch sealed along three edges, with one side left open for filling. After the product is loaded, the remaining edge is heat-sealed to create a secure package.
Compared with stand-up and flat bottom pouches, a three-side seal pouch has a simpler, space-efficient construction suited to single-use and small-format products, vacuum packaging, powders, granules, flat food items and trial-size packaging.
