Corrugated Sheets

What are corrugated sheets?

Converting-grade corrugated sheets in 3, 5 and 7-ply — cut to your exact dimensions for converters, layer pads and in-house packing lines.

We supply flat, warp-controlled sheets with consistent flute geometry and GSM — whether you convert them, use them as layer pads, or protect surfaces in shipment.

How we manufacture it

These formats are converted on precision die-cutting and creasing tooling maintained to tight tolerances — the difference between an insert that grips and one that rattles is fractions of a millimetre. Tooling is developed from your sample or drawing, prototyped, drop-tested where relevant, and only then released to production.

Choosing the right spec

Specify these formats from the product outwards: unit dimensions and weight fix the cell or cavity size; count-per-pack fixes the sheet layout; handling method (manual, line-side, automated) fixes board grade and style. Send a drawing, a sample or even a photo with dimensions and we will develop the format from it.

Engineering & standards — IS 2771 (Part 1): 2022

Indian corrugated boxes are governed by IS 2771:2022, which ties board type to the maximum mass of contents and prescribes minimum bursting strength and — new in the 2022 revision — a minimum Edge Crush Test value. The rows relevant to corrugated sheets:

3-Ply · Single wall
5-Ply · Double wall
7-Ply · Triple wall
Board construction

Kraft liners (dark) bonded to fluted medium (waves). More walls = more stacking backbone — the exact minimums are in the IS 2771:2022 table below.

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.

Strength you can calculate

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.

Sustainability & commercials

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.

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.

Frequently asked questions

Do you supply sheets to other converters?

Yes — consistent, warp-controlled sheet supply is a standing part of our production programme.

What sheet sizes can you cut?

Any practical size — sheets are cut to order rather than sold from a fixed chart.

What is the GST rate and HSN code for corrugated sheets in India?

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.

What is the minimum order quantity and lead time?

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.

Do you deliver corrugated sheets near me in South Gujarat?

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.

Need corrugated sheets engineered to your spec?

Serving Surat, Hazira, Bharuch, Ankleshwar, Vapi, Navsari, Vadodara and all of industrial Gujarat within 160 km — plus pan-India programmes.
