500-Pouch Factory Acceptance Test (FAT) & `-0.08 MPa` Seal Protocol

Verify >=99.5% zipper & bottom-gusset opening, no-pouch/no-fill interlocks, 8-minute width reset, powder seal-zone cleanliness, and `-0.08 MPa` burst testing.

Six Real-World Tests Every Premade Pouch Machine Must Pass Before Shipping

Running 20 empty bags on a showroom floor proves nothing about how a rotary pouch machine handles static-clinging zipper bags, dusty protein powder, or 4-layer box-pouch side gussets! Grounded in pouch sizing and ROI planning and pouch formats and sealing specs, ship 300–500 actual production pouches per extreme SKU (smallest + largest + thickest laminate) and execute this 6-point FAT.

Every metric below is objectively measurable on video or in person.

Station 8 water-cooled chill pressing flattens molten PE under mechanical pressure so heavy pouches never creep open.

Six-Point Premade Pouch FAT Acceptance Matrix

Pass/fail thresholds used prior to machine release:

FAT Test Item Challenge Procedure Mandatory Pass Criterion
1. Sustained Opening Rate Run 300 continuous zipper/gusset bags w/ product >=99.5% full mouth & bottom-gusset open
2. Unopened-Bag Interlock Tape 3 pouch mouths shut inside magazine stack 0 g spilled; filler inhibited; bags discharged unsealed
3. Submerged Vacuum Leak Test 20 filled pouches @ -0.08 MPa for 60 sec 0 bubble streams across side-gusset step transitions
4. Seal Cosmetic & Peel Inspect chill-pressed top weld + tensile pull Flat wrinkle-free weld; delamination peel >=25–45 N/15 mm
5. Motorized Width Reset Switch min width (120 mm) to max (250 mm) <=10 minutes total; 1st filled bag square & centered
6. Weight & O2 Repeatability Weigh 50 consecutive bags + needle O2 check Within ±0.5–1.0 g (weigher) & <1.5% residual O2

If vacuum cups fail to open a defective pouch at Station 3, the PLC inhibits the weigher/auger dump so zero product spills and the bag recycles.

Premade Pouch Engineering Notes

  • Test Both Matte-Varnish & Glossy Laminates: Matte soft-touch BOPP/PET outer layers have different friction coefficients under magazine pick cups and different heat-transfer rates under seal bars than glossy PET—test both if your brand uses them!
  • Check Gripper Pad Marks on Delicate Metallic Films: Verify carbide/rubber gripper tension holds filled weight securely without embossing visible teeth marks into soft foil shoulders.
  • Record Exact HMI PID Temps, Pressures & Cam Angles: Save every validated SKU’s seal-bar temperatures (°C), dwell angles, and air-blast timings directly in the shipped recipe backup.

Pouch width range determines turret frame size (200 mm vs 250 mm vs 320 mm); never buy one oversized 350 mm turret for tiny 90 mm bags.
