Leak-Proof High-Speed Takeaway Packets Without Greasy Cross-Seals
A single leaking chili-oil or soy-sauce sachet ruins an entire 500-count QSR restaurant carton! Inside sauce sachet, cup, and pouch machines, automatic liquid sachet and stick VFFS machines (5–100 ml standard; up to 199 ml dressing/marinade) pair suck-back pneumatic/servo pistons, water-jacketed agitated hoppers (up to 85 °C), and high-pressure serrated jaws with ionomer/mLLDPE laminate films (PET/Alu/PE or PET/VMPET/LLDPE).
Scale from compact single-lane 30–60 BPM restaurant co-packers (600 × 1,110 × 1,450 mm) up to 4, 6, 8, and 10-lane industrial QSR suppliers outputting 180–500+ sachets/min integrated directly with count-cartoners.

Sanitary Sauce & Hot-Fill Notes
- Vacuum Suck-Back Valve Cuts Oil Threads Cleanly: At the end of each piston stroke, reverse micro-suction pulls the final droplet 3 mm back inside the stainless filling tube so zero oil hangs into the horizontal cross-seal path.
- Squeeze-Through-Liquid Mode Eliminates Air Pillows: Closing horizontal jaws right through the sauce column produces flat, air-free QSR ketchup packets that withstand parcel shipping and aircraft cabin pressure changes without bursting!
- Perforated Linked Chains for Instant-Noodle Twin/Triplet Packs: Program software counters to perforate 2 or 3 linked sachets (
oil + dry soup + chili) or cut single loose takeaway packets on demand.
