Project Brief

Secondary Multipack Baggers & Woven-PP / PE Master Baler Systems

Group 4–24 primary pillow packs into retail multipack bags (5×RQ550 into 3×R800 topology) or pack 5–25 kg counts into 140–180 μm PE / woven-PP master bales.

Bag-in-Bag Economics: Retail Variety Packs & Corrugated Replacement

Secondary flexible bagging solves two distinct commercial missions inside secondary multipack and cartoning: retail multipacks (e.g., 6 × 30 g potato chip pillow packs inside a printed 180 g supermarket outer bag) and industrial master baling (grouping 10–50 primary pouches of rice, sugar, flour, detergent, or pet food inside a tough 140–180 μm M-fold PE or woven-PP outer bale, cutting shipping packaging cost 50–65% vs corrugated boxes).

Reference snack topologies link five 120 BPM primary VFFS machines (RQ550 class) directly into three large-tube secondary baggers (R800 class) via inclined collector conveyors and count-check gates.

Flexible pouches require flatteners and orientation control before case loading, whereas rigid bottles use lane dividers.

Retail Multipack VFFS vs Industrial Master Bagger Specs

Specification comparison across outer bag dimensions, film gauge, and collation:

Specification Retail Multipack VFFS (R800 Class) Horizontal / Vertical Master Bagger
Outer Bag Width × Length 180–400 × 220–550 mm 350–450 × 650–900 mm (gusseted 80–150 mm)
Outer Web / Bag Material 50–90 μm laminated BOPP/CPP or PE 140–180 μm M-fold LDPE roll or premade woven PP
Count Range & Payload 4–24 packs (120 g – 1.5 kg) 10–50 packs (5 – 25 kg shipping bale)
Cycle Speed 25–65 multipacks/min per bagger 6–18 tightened brick bales/min
Drop Cushioning Angledforming tube + air-expulsion sponges Horizontal compression plunger -> tight rectangular bale

Every downstream station is sized with progressive speed headroom so minor tape or blank reloads never halt primary filling.

System Integration Engineering Notes

  • Controlled Deflation Without Crushing Chips: Secondary snack baggers use timed soft-foam gusset tuckers and micro-perforations so outer multipacks palletize flat without popping inner N2-flushed bags.
  • Brick-Shaped Master Bales Stack Like Boxes: Horizontal compression master balers square 1 kg flour/sugar pouches into tight brick bundles that stack 8–10 layers high on export pallets with zero corrugated board.
  • Dual-Checkweigher Missing-Pack Divert: Any multipack weighing 1 primary-bag light is blown off onto a rework table so operators slit only the outer film and recover all good inner packs.

V-curve over-speed cascade ratios from 100% process feed to 130% end-of-line palletizing
Designing secondary case packers at 120–125% of primary output allows buffer conveyors to drain automatically after micro-stops.
