We design and manufacture complete corrugated packaging solutions — boxes, sheets, trays, inserts and printed cartons — as one accountable supplier for Gujarat industry. This guide covers the governing IS 2771:2022 specifications, strength and moisture engineering, commercial terms (GST 5%, HSN 4819) and exactly how to specify the right box.
We design and manufacture complete corrugated packaging solutions — boxes, sheets, trays, inserts and printed cartons — as one accountable supplier for Gujarat industry.
One engineering conversation covers your outer shipper, inner protection and branding, so components fit each other and your line — not just the price sheet.
Indian corrugated boxes are governed by IS 2771 (Part 1): 2022. The bands relevant here:
| Board type | Max contents | Max L+W+H | Min bursting strength | Min ECT |
|---|---|---|---|---|
| Single wall (3-ply) | Up to 5 kg | 635 mm | 6 kgf/cm² | 3.0 kN/m |
| Up to 8 kg | 900 mm | 8 kgf/cm² | 4.0 kN/m | |
| Up to 10 kg | 1125 mm | 9 kgf/cm² | 4.25 kN/m | |
| Up to 15 kg | 1275 mm | 10 kgf/cm² | 4.5 kN/m | |
| Double wall (5-ply) | Up to 20 kg | 1525 mm | 12 kgf/cm² | 5.0 kN/m |
| Up to 25 kg | 1715 mm | 13 kgf/cm² | 5.3 kN/m | |
| Up to 30 kg | 1905 mm | 14 kgf/cm² | 5.6 kN/m | |
| Up to 40 kg | 2286 mm | 17 kgf/cm² | 7.0 kN/m | |
| Triple wall (7-ply) | Up to 55 kg | 2667 mm | 24 kgf/cm² | 9.6 kN/m |
| Up to 75 kg | 2921 mm | 35 kgf/cm² | 12.4 kN/m |
Reference values from IS 2771 (Part 1): 2022, Bureau of Indian Standards — the governing Indian specification for corrugated fibreboard boxes. We engineer to or beyond these minimums for your load.
Stacking strength is engineering, not guesswork. Box Compression Test (BCT) capacity can be estimated with the McKee formula — BCT ≈ 5.87 × ECT × √(board caliper × box perimeter) — and then verified on the actual box. We apply safety factors of 2× for short-cycle distribution up to 4× for long-hold warehousing (per ASTM D642 practice), because long-term usable strength under load creep is only 50–60% of the peak laboratory value.
Production runs on a fully automatic corrugation line: kraft reels are conditioned and stored dry, fluted and bonded into 3/5/7-ply board, then printed, slotted, creased, die-cut and joined in a continuous, monitored flow. Automation is why lot 40 matches lot 1 — flute geometry, bond strength and blank dimensions are machine-held, not operator-remembered.
Choosing the right specification starts with three questions: how heavy is the packed box, how high will it stack (and for how long), and how humid is the journey? Weight and stack height set the ply and ECT; duration adds a creep safety factor; humidity decides whether standard kraft or Cobb-controlled coated board is the honest choice. Share those three facts and our engineers will spec the rest.
Commercially, corrugated boxes fall under HSN 4819, and GST on corrugated boxes was reduced from 12% to 5% with effect from 22 September 2025 — worth re-checking on old supplier quotations. Pricing is driven by board grammage (GSM), ply, kraft paper prices (which rose ~6% through 2025), printing and quantity; we quote engineered specifications within 4 business hours, offer sampling before you commit, and support everything from trial lots to annual rate contracts.
Every tonne of recycled-fibre corrugated board avoids roughly 180 kg of CO₂ versus virgin production (DEFRA life-cycle factors), and industry equivalences credit each tonne of recycled paper with saving about 17 trees, ~26,500 litres of water and ~4,000 kWh of energy (US EPA). Corrugated is also India’s practical answer to the single-use-plastic phase-out: recyclable, repulpable and biodegradable in weeks rather than centuries.
Yes — that is the model. Shippers, inners and printed unit cartons from one plant, one QC system and one dispatch schedule.
We start from your product weight, fragility and transit route, then engineer structure and board grade, sample it, and lock the spec before production.
Corrugated boxes fall under HSN 4819; GST was reduced from 12% to 5% effective 22 September 2025 (56th GST Council). We invoice at the current applicable rate with full documentation.
MOQs depend on size and print complexity — trial lots are welcome, and repeat production is scheduled to committed dispatch dates. Sampling comes first on request; quotations are returned within 4 business hours.
Yes — scheduled routes cover the full 160 km radius around our Kosamba, Surat plant (Surat, Hazira, Navsari, Bharuch, Ankleshwar, Vapi, Valsad, Daman, Silvassa, Vadodara), with pan-India full-truck programmes beyond it.
