Bulk Courier Bags Wholesale: How to Buy Without Getting Stuck

Buying courier bags in bulk feels like an easy saving. The price per piece drops, you don't run out mid-dispatch, and you stop placing small orders every week. But we've also seen sellers buy 10,000 bags of a size they stopped needing, or a big lot of bags whose flaps don't stick in winter. Here's how to get the saving without the dead stock.

1. Work out how many bags you really use

Take your last 30 days of orders and count how many went out in each bag size. That's your monthly use. A simple rule:

• Fast-moving sizes (your top 2 or 3): buy 1 to 2 months of stock.
• Occasional sizes: buy the smallest pack that covers a month.
• New products: buy a small pack until the product proves it sells.

Example: if you ship 60 orders a day and 70% go in 10×14 bags, that's about 1,260 bags a month in that size. A 2,000 to 2,500 bag order covers you for 6 to 8 weeks.

Not sure which size each product needs? Find it once with the polybag size calculator and write it next to the SKU.

2. Test before the big order

Bulk is where bad quality hurts most, because you're stuck with it. Order a small pack first and check:

• Seal: seal one, wait 10 minutes, try to peel it. It should tear the bag, not lift off.
• Thickness: 50 to 60 micron is the common range for clothing. Ask the supplier what the bag is, and compare by feel with a bag you trust.
• Seams: pull the sides. They shouldn't split before the film stretches.
• Size: measure it. A "10×14" that's actually 9.5×13.5 won't fit your product.
• Opacity: hold it to light with a printed paper inside. You shouldn't be able to read it.

Then reorder the same product from the same supplier, so quality stays consistent.

3. Buy with a GST invoice

Courier bags carry 18% GST. If you're GST registered, that's money you get back as input credit, but only if the invoice has your GSTIN. On a ₹20,000 bulk order, about ₹3,050 is GST. Enter your GSTIN at checkout every time. More in GST invoice for courier bags.

4. Store bulk bags properly

• Keep bags flat, in their cartons, off the floor.
• Keep them away from direct sun and heat. Heat can weaken the adhesive or make it stick to the release liner.
• Use older stock first.
• Keep each size and each marketplace's branded bags in separate, labelled bins.

5. When does custom printing make sense?

Printed bags with your brand name look good, but they need a minimum order, take time to make and lock you into one design and size. On marketplaces, the shipping label covers much of the bag anyway. Custom printing usually makes sense when:

• You ship a few thousand orders a month on your own website, Instagram or WhatsApp
• Your sizes are stable
• You want repeat customers to recognise your parcel

MarkRTD takes custom printed polybag orders in your size, colours and quantity, with a quote and GST invoice.

6. Plain vs marketplace bags in bulk

Plain tamper-evident bags are the safest bulk buy, because they work on every channel. Buy marketplace-branded bags in bulk only for the marketplace where most of your orders come from. If marketplace packaging rules change, plain stock can still be used on your other channels.

Bulk buying checklist

• Monthly use per size counted from real orders
• Small test pack passed seal, seam, size and opacity checks
• GSTIN on the invoice
• Storage space ready, flat and dry
• Next reorder date in your calendar, two weeks before stock runs out
