Finished PP woven bags
A woven PP sack is made from flat polypropylene tape woven into fabric, so it is strong for its weight and does not rot. Our open-mouth sewn-bottom bags use fabric of about 50–120 g/m², tape of about 650–1,200 denier, and carry up to 4-color flexo print. Options include a polyethylene liner, BOPP lamination for a glossy printed face, UV stabilization for outdoor storage, and micro-perforation so filled bags vent air and stack well.
Sizing is where most orders go wrong. The same 50 kg of rice, flour and compound feed occupy very different volumes, so the bag cannot be picked from weight alone. Send a product sample and we work back from bulk density. If your fill line is automatic, say so, because mouth stiffness and edge finish then matter. Valve, block-bottom and bulk bags are separate types and are quoted separately.
Roll-fed press for woven fabric
If you convert your own bags, a roll-fed press prints the fabric before cutting and sewing. Our MM-WFX takes rolls up to 1,200 mm in diameter and 750 mm wide, prints up to 650 mm, and runs 50–100 m/min nominal. Total power is 33–34 kW and weight about 3,900–4,500 kg depending on the version, so check the floor and the three-phase supply. Hot-air dryers sit after each color; register on woven fabric is typically about ±1–2 mm, which is a property of the fabric, not a fault.
A rough output check: at an 800 mm repeat and 80 m/min, theoretical output is about 100 repeats a minute. Real output is lower after roll changes, plate changes and ink adjustment, so plan from a shift figure, not from the nameplate. Stack-type presses with more decks exist on the market (one maker lists 4 to 10 decks at 120 m/min), but they are a different, larger machine class.
Narrow-web press for labels and film
Labels, film and cartons need fine register and thin substrates. The MM-NLF is modular, 2–10 colors, with anilox from about 200–1,200 lines per inch and register about ±0.1 mm. IR, UV or LED UV drying is chosen by material. Add die-cutting, foil, lamination or inspection modules as the job requires; choose the base frame for the growth you expect, because adding units later depends on it.
