Good ecommerce packaging in India does three jobs. It survives conveyor sorting, stacked bags and several handovers. It keeps volumetric weight (L × B × H in cm ÷ 5000) at or below the product's actual weight slab. And it leaves evidence if something goes wrong. Use the smallest pack that protects the product and seal it with tamper-evident tape.
Should you use a box, a mailer or a pouch?
| Pack type | Best for | Watch out for |
|---|---|---|
| Poly mailer (courier bag) | Apparel, textiles, soft accessories | No crush protection; it is plastic packaging for EPR purposes |
| Kraft paper mailer | Apparel, books, flat items, plastic-free branding | Tears when wet, so add an inner bag in the monsoon |
| Padded or bubble mailer | Small accessories, jewellery, cables | Too thin for glass or anything with corners that can puncture |
| 3-ply corrugated box | Most light products, items already in a retail carton | Crushes under heavy stacking; corners give way with heavy items |
| 5-ply corrugated box | Heavy, fragile or multi-item orders | Costs and weighs more; overkill for light goods |
| Rigid branded box | Gifting, premium launches | Expensive, and still needs an outer shipping box or strong wrap |
Mailers have a pricing edge on some networks. Delhivery's help centre, for example, says shipments packed in flyers are charged on dead weight up to 1 kg, which means no volumetric penalty for a puffy hoodie. Check how your own courier treats flyers before you switch.
What is the difference between 3-ply and 5-ply boxes?
A 3-ply box has two flat liner sheets with one fluted (wavy) layer between them. A 5-ply box has three liners and two fluted layers, so it resists crushing and puncture much better. The extra layers add cost and a little weight, but they matter when parcels sit at the bottom of a sack or a cage.
As a rough guide, 3-ply works for light items and anything already in a sturdy retail carton. Move to 5-ply for heavier parcels (a few kilos and up), glass, ceramics, appliances and orders with several items rattling together. Ask your supplier for the paper grade (GSM) and bursting strength of each box, then drop-test a packed sample from waist height onto each face and corner before you place a bulk order.
How does right-sizing cut your shipping cost?
Couriers bill on the higher of actual and volumetric weight, rounded up to the next 500 g. An oversized box makes you pay to ship air. Assume a skincare gift set that weighs 0.8 kg packed, shipped on a metro-to-metro (Zone C) lane at an illustrative ₹43 for the first 500 g and ₹24 for each additional 500 g.
| Box (cm) | Volumetric weight | Chargeable weight | Billed slab | Base freight |
|---|---|---|---|---|
| 30 × 25 × 15 | 11,250 ÷ 5000 = 2.25 kg | 2.25 kg | 2.5 kg | ₹139 |
| 25 × 20 × 12 | 6,000 ÷ 5000 = 1.20 kg | 1.20 kg | 1.5 kg | ₹91 |
| 22 × 16 × 10 | 3,520 ÷ 5000 = 0.70 kg | 0.80 kg (actual is higher) | 1.0 kg | ₹67 |
The smallest box saves ₹72 per parcel against the largest, about ₹85 once 18% GST is added. At 2,000 orders a month that is roughly ₹1.7 lakh. Shrinking below 22 × 16 × 10 saves nothing more, because the 0.8 kg actual weight already bills as 1 kg. Run your own sizes through the volumetric weight calculator and stock two or three box sizes that cover 90% of your orders, instead of one big box for everything.
What void fill should you use?
- Crinkle or kraft paper: cheap, recyclable, good for light items and gift presentation.
- Air pillows: very light, good for filling gaps, weak against sharp corners.
- Bubble wrap: the default for glass and ceramics; wrap the item, then fill the gaps.
- Moulded pulp or corrugated inserts: best for repeat SKUs, since they hold the product in place and pack fast.
- Foam: for electronics and high-value items where the product must not move at all.
Then do the shake test. Close the box and shake it. If you can hear or feel the product move, add fill. If the box bulges, the box is too small or overfilled, and a bulging box is exactly what triggers a re-measure and a weight dispute later.
How do you pack fragile items, liquids, apparel and electronics?
- Fragile (glass, ceramics, candles): wrap each piece separately, use a box-in-box with cushioning on every side, and keep pieces from touching. Use 5-ply for anything heavy.
- Liquids (oils, serums, sanitiser): tape or shrink-band the cap, seal the bottle in a zip bag with an absorbent pad, and pack upright where you can. Perfumes and aerosols have extra courier rules, covered in our guide to shipping perfume, liquids and batteries.
- Apparel: fold to the mailer size, use an inner polybag in the monsoon, and choose a mailer with a tamper-evident adhesive strip.
- Electronics: keep the retail box and put it inside a shipping box with fill; photograph the serial number before sealing. Lithium batteries need declarations and may be refused on air services.
How do you pack so you can win a dispute later?
Packaging is your evidence file. Three habits cover most cases. Seal every parcel with printed tamper-evident tape, so a reopened parcel is obvious at delivery. Record a short packing video at the station with the order ID or AWB visible, which answers 'empty box' and 'wrong item' claims. And photograph the sealed parcel on the scale with a tape measure in frame, because weight claims are decided on weight in grams and dimensions in centimetres. Delhivery's dispute form, for instance, asks for exactly those plus package images.
Many sellers also ask buyers to record an unboxing video before raising a damage claim; print that request on a card in the box, not only on your policy page. Finally, stick the label flat on the largest face, away from seams and edges, and remove old labels from reused boxes. Our shipping label guide covers what the label must carry.
Is branded packaging worth the cost?
Sometimes. Assume a plain 3-ply box costs ₹14 and a custom-printed one ₹26 at your order quantity. At 2,000 orders a month, printing adds ₹24,000. For a gifting brand whose buyers post unboxings, that can be cheap marketing; for a refill brand, it rarely pays back. A plain box with printed tape and a thank-you card carries the brand for a fraction of the cost. Never let branding push you into a bigger box.
Do you need EPR registration for plastic packaging?
Possibly. Under the Plastic Waste Management Rules, 2016, the Ministry of Environment notified Extended Producer Responsibility (EPR) guidelines for plastic packaging on 16 February 2022. CPCB's centralised EPR portal registers producers, importers and brand owners, and CPCB's FAQ notes that brand owners include online platforms and marketplaces. Flexible packaging such as pouches and covers made of plastic sheet is one of the covered categories. Entities operating in more than two states or UTs register with CPCB; those in one or two register with the state pollution control board or committee.
CPCB's FAQ says micro and small brand owners are exempted from fulfilling EPR obligations, but the rules have been amended more than once since 2022. Check the current position on the CPCB portal. This is general information, not legal advice; confirm with a compliance adviser.
How do you set up a packing station that gets this right every time?
- 1List your top 20 SKUs with packed dimensions and weight, and pick two or three pack sizes that cover most orders.
- 2Fix a SKU-to-pack chart at the packing table, with the void fill and tape for each.
- 3Weigh every packed parcel and enter real weight and dimensions in your shipping system, not catalogue values.
- 4Seal with tamper-evident tape, record the packing video and photograph the parcel on the scale, all against the AWB.
- 5Label the largest flat face and do a final shake test.
- 6Review weight-discrepancy flags weekly on the weight discrepancy dashboard and fix the pack spec for any SKU that keeps appearing.
Frequently asked questions
Use 3-ply for light products and items already in a sturdy retail carton; it is cheaper and lighter. Use 5-ply for heavier parcels, glass, ceramics, appliances and multi-item orders, because the extra liner and fluted layer resist crushing in stacked sacks and cages. When unsure, drop-test a packed sample on each face and corner before ordering in bulk.
Yes, for soft and unbreakable items such as apparel, textiles and some accessories. Mailers are lighter, cheaper and avoid volumetric penalties, and some couriers bill flyer shipments on dead weight up to 1 kg. Do not use them for glass, liquids, electronics or anything with corners that can puncture the bag. Choose one with a tamper-evident seal.
Leave enough room for cushioning on every side and no more. Fragile items need a few centimetres of fill all round, ideally in a box-in-box setup. For sturdy items, a snug fit with a little fill is enough. If the product moves when you shake the box, add fill; if the box bulges, go up one size.
Producers, importers and brand owners that use plastic packaging must register on CPCB's centralised EPR portal under the Plastic Waste Management Rules, and CPCB counts online platforms and marketplaces among brand owners. CPCB's FAQ exempts micro and small brand owners from EPR obligations, but the rules have changed since 2022, so confirm on the portal or with a compliance adviser.
