Not sure which diameter fits your pouch? Send us the spout drawing — we confirm the match before quoting.
Reason 1 — Seal holds through filling and transit.
Threaded closure plus tamper ring. Caps are spot-checked for leakage before packing, so downstream filling lines see fewer rejects.
Reason 2 — Fits the pouch you already run.
Standard diameters cover most stand-up pouch and sachet spouts in the market. No new tooling needed for common sizes.
Reason 3 — Custom work does not stall the order.
Color, logo and orifice changes run on existing molds. Only a new spout neck requires tooling — and that is quoted separately and transparently.
Reason 4 — Repeat orders stay repeatable.
Same mold, same material grade, same packing. Buyers reordering six months later get the same fit.
What is checked before shipment:
| Test | Method | Purpose |
|---|---|---|
| Thread fit check | Cap-on-spout torque and turn test | Confirm closure engages fully |
| Leakage spot check | Filled pouch inverted / compressed | Catch seal failure before packing |
| Tamper ring function | First-open tear test | Verify ring breaks cleanly, stays attached |
| Dimension check | Go/no-go gauge on ID and height | Keep fitment within tolerance |
| Carton drop test | Loaded carton drop | Protect caps in transit |
Buyer takeaway: Test reports and batch records can be shared with your QC team on request.

Filling line notes
Compatible with common spout-insertion and cap-capping stations.
Cap torque can be tuned to your capping head — share the setting and we match the thread tolerance.
For hot-fill lines, confirm temperature range with our team before ordering; material grade can be adjusted.
Bulk caps are supplied pre-oriented where the capping machine requires it.
One sentence: Tell us your pouch spec and capping equipment — we flag fitment risks before the PO, not after.
Beverage & liquid food: juice pouches, sports drink doypacks, isotonic/hypotonic formulas, flavored water, soy milk.
Sauce & paste: ketchup, mayonnaise, tomato paste, condiments — 9.6mm opening suits controlled pour for mid-viscosity products.
Dairy & puree: yogurt drinks, fruit puree, jelly pouches.
Non-food compatible lines: liquid detergent refill pouches, personal care liquids (same fitment, separate material verification if required).
