What is a 3 side seal pouch?
A 3 side seal pouch is a flat, laminated pouch sealed on three edges with one open side for filling. After filling, that open side is sealed, creating a slim, protective pack ideal for samples, single-serves and inserts across food, beauty and wellness.
Entity view:
- Entity: 3 side seal pouch
- Attributes: size, film structure, barrier level, notch, hang hole, finish
- Values: small/medium/large, standard/high barrier, with/without tear notch, matte/gloss/soft-touch, hang or non-hang
We lock a spec so you can run many SKUs on the same flat pouch family.
When should you use 3 side seal pouches instead of stand-up pouches?
Use 3 side seal pouches when products are flat, single-serve, sample-sized or meant to live inside another box. Stand-up pouches are better for larger volumes and primary shelf presence; 3 side seal pouches are for tight, low-profile, efficient packaging.
Best use cases:
- Shipping samples, sachets or trial sizes
- Packs that slide into kits, mailers, or ship-flat bundles
- Products that don’t need to stand on their own
- Minimal material usage with maximum efficiency
- Controlled single-dose or small portions
Which products fit best in 3 side seal pouch packaging?
3 side seal pouch packaging fits single-serve snacks, drink mixes, powders, capsules, wipes, masks, beauty samples, pet treats and small hardware or accessory kits, where a slim, sealed pack beats a bulky jar, box or stand-up bag.
Common fits:
- Food & beverage: single-serve nuts, trail mix, jerky, candy; coffee sachets, tea envelopes, drink powders; condiments, sauces, spice and seasoning packs
- Beauty & personal care: face masks, under-eye patches, wipes, towelettes, serum/cream/shampoo samples
- Health & wellness: capsule and tablet dose packs, hydration, energy and vitamin stick packs
- Other: pet treat samples; cables, screws, small hardware or accessories; instructional packs, welcome kit inserts
What features should a 3 side seal pouch include?
