3-side seal pouch, also known as a flat pouch or sachet, is an excellent choice for point-of-sales packaging, single-serve items, on-the-go snacks, or tester-size products. These individual flat bags serve as simple and effective packaging for small portions.
3-side seal pouches offer a highly efficient and secure flexible packaging format, engineered for precision sealing and reliable protection across food and non-food sectors. Their clean, flat construction makes them ideal for products requiring strong barrier performance and compact storage. Structures can include PET/PE, PET/AL/PE, or recyclable mono-material films, tailored to achieve specific oxygen, moisture and aroma barrier requirements.
3-side seal pouches are a smart choice for brands looking for efficient, cost-effective, and secure packaging. With seals on three sides and one open edge for filling, these pouches offer excellent product protection and a slim, space-saving profile which is ideal for single-serve formats, powders, or flat items like supplements or wipes. Their simple structure allows for a wide range of barrier materials, making them compatible with both high-barrier and recyclable films.
Whether used for food, cosmetics, or sample packs, our custom printed 3-side seal pouches deliver professional shelf appeal and easy customisation with printed branding or finishing options.
