Mailer box vs shipping box vs courier bag

Pick a mailer box when the unboxing moment matters, a regular-slotted shipping box when you need stacking strength or odd-shaped goods, and a courier bag when the product is soft, light and does not need a rigid wall.

Mailer boxes

A mailer is a corrugated tray with a tuck-top lid and ear-lock. It ships flat, folds in seconds, and presents like a gift. PackWorks stocks plain white, kraft and nine signature colours. Best for cosmetics, jewellery, apparel accessories, subscription boxes and any D2C brand that photographs the open box.

Shipping boxes (RSC cartons)

A regular slotted carton (RSC) has four flaps that meet in the middle and is sealed with tape. It is the workhorse of Indian logistics — cheaper per cube, stronger when stacked, and available from jewellery flats (3 × 2 × 2 inch) to export cubes. Choose 3-ply or 5-ply on the product page.

Courier bags

Tamper-evident polyethylene bags with a permanent adhesive strip. They weigh almost nothing, so courier actual-weight slabs stay low. Use them for garments, fabric, soft toys and documents — not for bottles, jars or anything that can puncture the film.

FAQ

Questions this guide answers

Is a mailer strong enough for India Post or Delhivery?

Yes for items that fit snugly and stay under a few kilograms. For stacking in a warehouse or tempo, use an RSC shipping box.

Can I put a bottle in a courier bag?

No. Use a bottle carton or a 5-ply cube with void fill. Film bags puncture and do not protect glass.

Which is cheapest per shipment?

Courier bags win on freight for apparel. For anything rigid, a well-fitted 3-ply RSC or mailer usually beats an oversized carton on volumetric weight.
