Sealing isn’t just about closing a bag — it’s about keeping products fresh, making packaging easy to use, and building trust with your customers. From choosing the right format to adding tear notches, zippers, and the right film, small decisions make a big difference in performance and shelf appeal.
Quick Summary For Sealing Stand Up Pouches
- Choose the right format — stand-up, flat bottom, or quad seal
- Pick the right materials + add a tear notch — thickness influences seal strength, and tear notches guide a clean first open
- Add a zipper if needed — resealable for freshness + convenience
- Keep it simple — aim for a clean top seal + smooth customer open
1. Pick Your Pouch Format
Format affects shelf presence and how customers use the pack.
- Everyday snacks and dry goods, stand up pouches.
- Heavier fills or cube efficiency, flat bottom pouches.
- Four panels for structure and story space, both flat bottom and quad seal pouches.
2. Choose The Right Materials
Film choice impacts both seal performance and sustainability.
- Finishes: Barrier, clarity, tactile, and metallized choices to fit your product and brand.
- Thickness & layers: Thicker laminates (like 3-layer with METPET) = stronger, cleaner seals. 2-layer PE is flexible but less precise on small formats.
- Sustainability: Recyclable PE PE (store drop-off eligible) and PCR content films provide eco options without sacrificing performance.

3. Make Opening Easy: Tear Notches
A tear notch is a small slit near the top seal.
- Works well with zippers, hang holes, and most stand-up pouches
- Shows customers exactly where to open — no scissors needed
- Creates a clean, simple first-open experience
4. Add Resealability (Zippers + Closures)
What is resealable packaging?
Bags you can open, then press shut again so the contents stay protected.
What are the benefits?
What makes our resealable bags a good choice?
Clean printing for your brand, flexible sizes, and features you can mix and match to fit your product. Explore options on our stand up pouches page and within our films and finishes. For regulated goods, see child resistant packaging.
Closure Options:
- Press to close zipper, everyday open and close
- Powder friendly zipper, made to close cleanly with fine product present
- Child resistant zipper, added safety for products that require it
- Tear notch, a small slit that guides an easy first open
5. Work With Your Co-Packer (If Needed)
Share simple details so rolls drop in without surprises, unwind direction, maximum outer diameter, core size, eye mark location, and preferred seal width. If needed, run a quick test run on their line to confirm the setup.
