Production line and factory setup overview
A small roll-fed paper-converting line producing handle-free flat and gusseted satchel bags with a sharp or V bottom from specified paper through reel loading, web guiding, optional one-colour flexographic printing, photocell registration, perforation where required, side gluing, tube forming, length cutting, bottom folding and gluing, counting, inspection and carton packing. It is distinct from a square-bottom shopping-bag line.
Recommended lowest-entry line configuration Launch one unprinted or one-colour flat/satchel bag for bakery, pharmacy or dry-food use. Screen a 230-720 mm roll-fed machine rated for roughly 40-90 gsm paper, with reliable web guide, photocell registration, water-based glue and counter. Confirm whether the buyer needs a flat bag, gusseted satchel, grease-resistant paper or food-contact documentation before ordering tooling.
Production process and implementation sequence
- Paper-reel receiving and conditioning
- Reel loading, tension and web guiding
- Optional one-colour flexographic printing
- Photocell register and optional perforation
- Side gluing and tube forming
- Length cutting and V-bottom formation
- Counting and dimensional inspection
- Carton packing and dry dispatch
Products, capacity and market fit
- Bakeries, pharmacies, snack makers and retailers use simple low-cost paper bags.
- No handle and a V bottom reduce paper, tooling and machine complexity.
- One bag size and print colour support short local runs.
- Food and grease-resistant applications require approved paper, ink and glue.
- Flat bakery or pharmacy paper bag - One width/length, paper gsm, V-bottom, glue, print and pack count - Bakeries, pharmacies, hardware and retail counters
- Gusseted satchel bag - Approved gusset, grease resistance and food-contact construction - Dry foods, snacks and takeaway products
