Ro box size and price — a practical guide from Packsmith India, a corrugated and printed box factory at IMT Kharkhoda, Delhi NCR. It gives sizes, board grades and indicative rates for RO purifier cartons.
If you assemble or sell water purifiers in Delhi NCR, the RO box size and price question comes up with every new model. This guide gives the standard RO carton sizes, the board and print choices that set the price, what an RO box costs in 2026 at different quantities, and how to brief a factory so the first sample is right. It is written by Packsmith India, an RO packaging box manufacturer at IMT Kharkhoda, 12 km from Bawana.
Standard RO box sizes (internal dimensions)
RO box size and price start with the cabinet. Measure the cabinet at its widest points including the tap, bracket and lid, add the polybag and the kit box, then add 5–8 mm clearance per side. Typical results:
| Purifier type | Typical cabinet | Typical RO box (internal, L×W×H) | Board |
|---|---|---|---|
| Wall-mount, 8–12 L tank | ≈ 400–420 × 230–250 × 450–480 mm | ≈ 430–450 × 260–280 × 500–520 mm | 5-ply BC/EB or heavy 3-ply |
| Compact / under-sink | ≈ 300–320 × 200–220 × 350–380 mm | ≈ 330 × 230 × 400 mm | 3-ply E/B |
| Counter-top / table-top | ≈ 350 × 250 × 400 mm | ≈ 380 × 280 × 440 mm | 3-ply or 5-ply |
| Commercial 25 L | ≈ 450 × 350 × 700 mm | ≈ 500 × 400 × 750 mm | 5-ply BC + corner inserts |
| Commercial 50 L | ≈ 550 × 400 × 900 mm | ≈ 600 × 450 × 950 mm | 5-ply BC, stitched |
Every brand’s cabinet differs, so an RO box size and price quote is always made to your drawing or sample; the box size calculator gives a first estimate.
What sets the price of an RO box
Four lines make up RO box size and price: board (55–65% of the cost), printing, conversion (die-cutting, gluing, inserts) and delivery. Within those, three decisions move the number most.
1. Board grade
A 5-ply box with 150 GSM liners costs noticeably more than a 3-ply box with 120 GSM liners, and a 180 GSM virgin kraft liner adds 15–20% to the board line over 150 GSM. Choose by stacking height and transit distance, not by habit; a dealer stacking three cartons high in a dry godown needs less than an e-commerce shipment through four hubs.
2. Print
One- or two-colour flexo on kraft is the cheapest and right for generic RO boxes. Four-colour offset on a duplex liner with UV coating is the retail standard for brands and costs more per box but sells on the dealer’s shelf. Metallic ink, spot UV and six-colour runs add a small premium.
3. Quantity per lot
Plates and make-ready are fixed costs, so a 5,000-piece lot is clearly cheaper per box than 1,000. The minimum at Packsmith is 1,000 per design; generic boxes in stocked sizes can be bought in smaller repeat lots once the first order is placed.
RO box price in Delhi NCR (2026 indicative)
Indicative RO box size and price bands for a standard wall-mount carton, delivered within Delhi NCR, at 1,000 and 5,000 pieces. Final prices depend on exact size, GSM and artwork, and paper prices move, so treat these as planning numbers and ask for a written quote.
| RO box type | At 1,000 pcs | At 5,000 pcs |
|---|---|---|
| Generic kraft 3-ply, 1–2 colour flexo | ₹ 32 – 45 | ₹ 28 – 38 |
| Generic kraft 5-ply, 1–2 colour flexo | ₹ 45 – 60 | ₹ 40 – 52 |
| Printed 5-ply, 4-colour offset + UV, with inserts | ₹ 70 – 110 | ₹ 60 – 95 |
| Kit box (printed, 3-ply) | ₹ 9 – 16 | ₹ 8 – 13 |
| Membrane / pump / filter mono cartons | ₹ 5 – 12 | ₹ 4 – 10 |
Trader prices for RO boxes made in three different units typically run 20–30% above a factory price for the same specification, because each hand-off adds a margin and a transport leg. Ask where printing, lamination and corrugation are done; if the answer names another company, add that to the comparison.
RO box banane wali company kaise chunein (Hinglish quick guide)
Bahut se RO assemblers “RO box banane wali company” ya “RO packing box price” search karte hain. Short checklist: (1) factory apni hai ya trader hai — printing, lamination aur corrugation ek jagah hone chahiye; (2) quote me har layer ka GSM aur bursting factor likha ho; (3) sample aapke actual cabinet ke saath bane; (4) kit box, membrane box aur pump box bhi wahi banaye; (5) delivery apni gaadi se fixed din par ho. In paanch baaton par RO box size and price dono clear ho jaate hain.
Packsmith India yeh sab IMT Kharkhoda me ek chhat ke neeche karta hai — Bawana, Wazirpur, Okhla aur Kundli tak apni gaadi se delivery.
How to brief a factory in one message
Send: cabinet dimensions (or a photo with a tape), weight with tank, box style (printed / generic / own-brand), number of colours, whether you need the kit box and accessory boxes, quantity per month, and your delivery address. You should get back a quote with board spec and price at 1,000 and 5,000, and a white-sample date within 48 hours. That one message settles RO box size and price in a day instead of a week.
FAQ: RO box size and price
What is the most common RO box size?

Minimum order? 1,000 per design. Lead time? 48-hour white sample, four-day printed sample, 7–10 working days bulk, 7 days repeats. Do prices include delivery? Yes, within Delhi NCR for lots above the minimum. For a quote, WhatsApp 98107 42123 or see the RO packaging box page; board standards follow the Federation of Corrugated Box Manufacturers of India.
Kit boxes, membrane boxes and pump boxes: the rest of the RO pack
RO box size and price is usually quoted for the outer carton alone, but a purifier ships with an installation kit (pipe, wrench, feed valve, tap, SMPS), and dealers also stock membranes, booster pumps and 10-inch filters in their own boxes. Making all of them with the same factory keeps the artwork consistent and the inner kit box sized to the cavity beside the tank so it cannot swing in transit.
Indicatively, a printed 3-ply kit box adds ₹9–16, and mono cartons for membranes, pumps and filters ₹5–12 each at 1,000 pieces. Ask for them on the same quote as the RO carton; the full set is detailed on our RO packaging box manufacturer page.
Ro box size and price: inside a single-roof carton factory
The practical side of ro box size and price is decided by six production steps that, at Packsmith India, all happen in one building. Pre-press checks artwork and makes plates on the CTP unit. The Heidelberg four- or six-colour press prints a 28×40 inch sheet with aqueous or UV coating applied inline. Wet lamination bonds the printed sheet to corrugated board with water-based adhesive and no heat, so the board stays flat.
The flute laminator produces E, B or C flute board in 3-ply or 5-ply in parallel. Die-cutting shapes the blank and strips waste; the Robus folder-gluer closes retail cartons and a stitcher handles heavy export shippers. A sample from every lot goes to the lab for bursting, edge-crush and Cobb tests before the bundles are strapped and loaded.
With no sub-contracting, the 7–10 working-day lead time quoted alongside ro box size and price holds in peak season when outsourced chains stretch to three weeks. The machines are shown on our packaging factory infrastructure page.
Ro box size and price and board specification
No discussion of ro box size and price is complete without flute and GSM. E-flute (about 1.5 mm) gives a smooth printable face for retail cartons. B-flute (about 3 mm) adds crush resistance with a decent print surface. C-flute (about 4 mm) is the standard shipping flute. Five-ply BC or EB board carries 25–40 kg through transit. Paper grade matters as much as flute: a 180 GSM virgin kraft liner behaves very differently from a 120 GSM recycled one, and bursting strength roughly tracks liner weight.
The rule of thumb we give buyers asking about ro box size and price: match the flute to the shelf, not the warehouse. If a shopper sees the box, start with E-flute and a printed duplex liner; if it only has to survive a truck, start with C-flute kraft and spend the saving on a heavier liner. Ask any supplier for the GSM of every layer and the bursting factor in writing; two quotes can only be compared on the same specification. Our corrugated box manufacturer page lists the standard grades.
Ro box size and price: offset, flexo and finishes
Offset printing on Heidelberg presses reproduces photographs, fine type and brand colours accurately; four-colour process covers most artwork and the six-colour press adds a Pantone or metallic with inline coating. Flexographic printing in one or two colours directly on kraft is cheaper and right for plain shippers. In ro box size and price terms, offset is the retail default and flexo the shipper default.
UV coating gives a hard gloss that resists scuffing. Wet lamination bonds the printed sheet to board with water-based adhesive and keeps it flat; we do not use thermal lamination. Spot UV, embossing and metallised film are available for premium ranges at a small premium. All finishing is done in the same building as printing, so ro box size and price never involves a sheet travelling between vendors.
Briefing artwork when ro box size and price is the project
Send the logo as a vector (AI, EPS, PDF, SVG), Pantone references or a printed item to match, and photographs at 300 dpi at printed size. Keep text at least 6 pt and 5 mm from folds and cut lines, because die-cutting tolerance is about 1.5 mm. Supply barcodes as vectors with the number beside them and name the panel they sit on. For the dieline, give internal product dimensions in millimetres, weight and how the box should open.
You receive a proof PDF with bleed and safe areas marked; approve by email or WhatsApp and the printed sample follows within four working days. This checklist is the fastest route from a ro box size and price enquiry to an approved sample. The box size calculator produces the dimensions in a minute.
Ro box size and price: what the lab report tells you
Every lot is tested for bursting strength (kg/cm²), edge crush (stacking strength) and Cobb value (water absorption), with the report attached to the invoice and kept three years under ISO 9001:2015. Box compression and drop tests with the real product are added when a buyer needs them. For ro box size and price, the test report is what lets you compare our quote with anyone else’s on equal terms.
Compliance printing is routine: FSSAI panels for food-contact outer cartons, BIS marks for pressure cookers and appliances, ISPM-15 and export shipping marks where a forwarder requires them. We are MSME and Udyog Aadhaar registered, and board standards follow the Federation of Corrugated Box Manufacturers of India.
What ro box size and price costs and why
Price is built from board (55–65%), printing, conversion and delivery. Quantity per lot and board grade move it most: a 5,000-box lot is noticeably cheaper per box than 1,000, and moving from a 120 GSM to a 180 GSM liner adds roughly 15–20% to the board line. Minimum order is 1,000 boxes per SKU and mixed-SKU orders can share a slot. Where ro box size and price is sub-contracted, each hand-off adds an 8–15% margin and a transport cost.
New accounts pay 50% advance and 50% before dispatch; established accounts move to 30-day credit after three clean lots. Quotes are valid 30 days and revised only when paper prices move more than 5%, flagged in advance. Common questions are answered in the packaging FAQ.
Ro box size and price: lead time and logistics
Our own vehicles deliver on fixed days to Bawana, Narela, Kundli, Badli, Wazirpur, Okhla, Gurugram, Manesar, Faridabad, Noida and Greater Noida, which lets a brand run on a week of carton stock rather than a month. Elsewhere in India, cartons ship flat on pallets by part-load transporter in two to four days with a test carton sent ahead. The ro box size and price timeline is 48 hours to a white sample, four working days to a printed one, 7–10 working days to bulk and 7 to a repeat.
Brands already on this schedule are listed on the packaging clients page and the boxes themselves in the packaging gallery.
Ro box size and price and recyclability
Corrugated board is among the most recycled materials in India. Our liners blend recycled fibre with virgin kraft, and a mill declaration of recycled content is available for sustainability reports. Water-based adhesives and wet lamination mean no solvent emissions; die-cutting offcuts are baled and returned to the mill. In ro box size and price, the biggest single sustainability gain is usually swapping foam inserts for corrugated ones. Ask for a mono-material sample and we show both options side by side.
Quick answers on ro box size and price
Minimum order? 1,000 boxes per SKU. Sample time? White in 48 hours, printed in four working days. Bulk lead time? 7–10 working days; repeats 7. Where do you deliver? Own fleet across Delhi NCR, transporter across India. Can you design the box? Yes, pre-press prepares dielines and adapts artwork. Certified? ISO 9001:2015, MSME, Udyog Aadhaar. Any other ro box size and price question: WhatsApp 98107 42123 or the contact page. Factory visits at IMT Kharkhoda are welcome any working day.
Ro box size and price: terms used on this page
Flute: the wavy inner layer of corrugated board; E, B and C are the common profiles. Liner: the flat paper on each face. Medium: the paper that is fluted. GSM: grams per square metre, the weight of a paper layer. Bursting factor: a strength figure for the finished board. ECT: edge crush test, a stacking-strength measure. Cobb: water absorption in a fixed time. Duplex: coated white board used as a printed top liner. Dieline: the flat drawing of a box with cuts and folds.
RSC: regular slotted carton, the standard shipper. Crash-lock: a base that locks when the carton is opened. Mailer: a one-piece e-commerce box with a tuck-in lid. Master carton: an outer box holding several retail units. Wet lamination: bonding a printed sheet to board with water-based adhesive. CTP: computer-to-plate. These are the terms a supplier will use when ro box size and price is discussed.
Ro box size and price: how to compare suppliers
Put both quotes on the same specification before you look at price. Ask each supplier for flute profile, the GSM of every layer, the bursting factor, print process and colour count, finish, insert type and whether delivery is included. If one quote lacks any of these, it cannot be compared. Then ask where each process happens; if printing, lamination or corrugation is sub-contracted, add that vendor’s margin and transit time.
Next, compare sampling terms: a supplier that charges for the first printed sample or takes two weeks to produce it is signalling how repeats will go. Finally compare paperwork: a per-lot test report and a signed colour sample should be standard. Applied to ro box size and price, this method typically exposes a 20–30% gap between trader and factory prices.
Ro box size and price: a two-hour factory visit
Visits to IMT Kharkhoda are welcome any working day; the plant is 12 km from Bawana, 9 km from Kundli and a direct expressway run from Manesar, Faridabad and Noida. Bring your current box and a product sample. In two hours you can see pre-press and the stored colour samples, watch a sheet come off the Heidelberg press, compare a laminated and a metallised sheet, note the flute types in stock, fold a box from the die-cutter and watch a bursting test on a live lot.
Most ro box size and price questions are answered in that walk, and the written quote follows the same day. WhatsApp 98107 42123 with a preferred date so the relevant samples and reports are ready. If a visit is not practical, the same walk-through can be done on a video call with the sample couriered afterwards.
Ro box size and price: five errors we see on first orders
Approving a dieline from a drawing rather than a 48-hour white sample; choosing board by price alone; sending JPEG logos that print soft; forgetting the barcode panel until the proof stage; placing text within 5 mm of a fold; and ordering a retail carton without its master carton so the two never fit. Each appears here because a real brand made it once, and our pre-press team checks for all of them before a proof goes out.
The costliest ro box size and price mistake is comparing prices at different specifications. Ask for the GSM, the bursting factor and the process location in writing, and the comparison becomes simple.
