Packing mehandi (henna) powder starts with measuring bulk behaviour on your floor, not copying another factory’s HMI recipe. For Mehandi, plan around 0.30–0.45 g/ml bulk density and plant powder (lawsone sensitive to moisture) as the primary materials variables. Recommended metering is auger after 40–80 mesh sieving (fill code AUGER). YugMach publishes configuration prices from Mathura so buyers get price transparency before GST; final figures still follow pouch size, film, and options. On mehandi lines, seal development usually begins near 130–160°C with dwell in the 0.4–1.0 s band, then moves after peel tests on your laminate lot. Gas or barrier target context is moisture control for dye strength. Typical films include PET/PE laminate, Metallised film, Moisture-barrier laminate. Pouch bands commonly cover 50g–100g, 200g–250g, 500g. Planning throughput sits near 1,000–2,000 when product, film, and changeovers cooperate. Critical failure modes unique to mehandi (henna) powder: lawsone vs moisture; green dust staining; stalk jams in throat; scorch in hot tube; WVTR-critical shelf life. Design SOPs and spare kits around those five, not around generic ‘packing machine maintenance’ checklists. Keep free-fall near 300 mm or lower when fracture or dust generation is a risk for this SKU family. Gas flushing is usually secondary or irrelevant for mehandi (henna) powder; moisture, alkalinity, count accuracy, or wrap integrity dominate instead. Spend engineering time on WVTR, corrosion resistance, and seal cleanliness rather than nitrogen plumbing you will never use. Weight control economics for mehandi: about 2 g average giveaway at 2,000 packs/hour wastes 4 kg/hour of product. Multiply by your factory cost per kilogram to size the payback for better tooling, more heads, or closed-loop checkweighing. Calibrate weekly with certified test weights and after any collision on the filler frame. Mechanical envelope: expect on the order of 3.5 kW class connected load depending on servos and heaters, and roughly 6 bar clean dry air if actuation is pneumatic. Film path width planning around 125 mm face/web context is a common starting point for mid retail SKUs, but collar selection must match the actual formed cross-section. Wrong collars score film, wander longitudinal seals, and create scrap that looks like a temperature problem. Mehandi dye strength tracks moisture; WVTR and seal integrity are product-performance specs, not only packaging specs. Sieve to remove stalks that jam auger throats — 40–80 mesh is a common starting band depending on grade. Green dust staining is cosmetic on floors but critical on seal faces; vacuum on a timer. Hot fill tubes can scorch plant powders and create bitter notes; keep tube temperatures modest. Do not store open mehandi hoppers overnight in monsoon RH without covers — potency claims die in the hopper before packing. Housekeeping for mehandi (henna) powder must match chemistry: wipe intervals, extractor filter changes, and elastomer replacement differ from a dry rice demo line. Never hose electrical cabinets. Dry contact parts fully after wet cleaning before restart. Document screw RPM or weigher combination limits, seal temperature, and flush settings on a laminated card at the machine for each mehandi SKU. Factory acceptance should include at least three steady hours on the hardest mehandi SKU with agreed scrap and weight or count tolerances. Record film lot, ambient °C, and RH — monsoon air in North India changes powder flow and snack oil feel. Train two operators and one fitter before sign-off; demand drawings, pneumatic diagrams, and password policy with the machine. Spare parts with lead time risk for mehandi lines include sealing jaws or Teflon, forming collars for each width, and filler-specific wear parts (auger flights, cups, weigher buckets, linear pans, wrap belts, or count sensors as applicable). Buying the cheapest film that ‘almost seals’ at 130–160°C usually raises scrap more than the reel savings. Commercial comparison: use published prices for price transparency, then insist on trials with your mehandi (henna) powder and your film. Numbers that decide the purchase are density, plant powder (lawsone sensitive to moisture), peel strength, giveaway or reject rate, and sustained packs per minute — not marketing adjectives. GST is extra on published tags; nitrogen, extra heads, and special MOC change the final configuration cost. For mehandi, revisit film COF if packs slip on inclined outfeeds; a 0.05 COF shift from a new reel lot can raise fall-over scrap without any machine fault. Operators packing mehandi (henna) powder should know the abort sequence for film break and hopper empty — untrained clears are a top source of bent jaws and cut fingers. Keep a scrap Pareto for mehandi with categories for seal, weight/count, and print; fund fixes for the tallest bar first. When ambient RH jumps 15–20 points, re-check the first 50 packs of mehandi (henna) powder before releasing the shift’s production. Align purchasing of film and spare collars for mehandi so a width change does not strand the line waiting for tooling. For mehandi, revisit film COF if packs slip on inclined outfeeds; a 0.05 COF shift from a new reel lot can raise fall-over scrap without any machine fault. Mehandi packed for bridal seasons sees demand spikes; keep spare augers and calibrated scales ready rather than overspeeding and creating underweights. Lawsone assays on retain samples protect you when retailers claim weak stain that was actually high moisture ingress from a bad film lot. Avoid transparent windows if UV exposure on shelf is likely.
