Q:What products are suitable for 3-side seal pouches?

A:They are widely used for single-serve sachets, samples, face masks, coffee drip bags, frozen seafood, and vacuum packaging. Flat, compact design makes them ideal for high-speed filling lines.

Q:What standard accessories are available for this pouch type?

A:Standard accessories include dual tear notches, rounded corners (R3/R5), and hang holes (Euro hole or round hole). These improve opening convenience and retail display.

Q:What seal widths do you recommend?

A:Seal width is usually 5 mm, 6 mm, or 8 mm. For heavier or vacuum applications, 8 mm is recommended to maintain seal strength under vacuum or freezing.

Q:What material structures are most common?

A:PET/PE and BOPP/CPP are economical for general products. PET/VMPET/PE or PET/AL/PE provide higher barrier. MDO-PE/PE is used for recyclable applications, and PCR or compostable films are also available.

Q:Can I add a zipper to a 3-side seal pouch?

A:While possible, zippers are less common on standard 3-side seal pouches because they are often used for single-serve or vacuum applications. If you need a resealable flat pouch, we can discuss a custom design.
