Size stickers for clothing bags let a picker, packer or shop assistant read the size, and often the colour and style, of a garment without opening its bag. Velocity Wear applies size stickers and custom labels to its printed zip-seal bags, matched to your size run, at 50 bags per design, with 10 to 15 working days of production from artwork approval.

Why should the size be readable without opening the bag?

Because every bag opened to check a size has to be refolded, resealed and sometimes replaced. In a warehouse, a clear size sticker makes picking faster and cuts wrong-size orders, which otherwise come back as returns. On a shop floor, staff can find a medium in a stack in seconds, and customers can check a pegged bag without pulling it apart. Frosted film shows a garment's shape and colour, but the neck label is rarely legible through it, which is why every bag in our printed polythene bag range can carry a sticker on the outside.

What can a label on the bag carry?

Barcode labelA scannable code for the item, where a retailer requires oneStockists and marketplaces at goods-in

An SKU, or stock keeping unit, is the internal code a brand uses for one exact item, for example a black hoodie in medium. SKU stickers are labels carrying that code, and they suit warehouses that pick by code rather than by eye. They can sit alongside a plain size sticker rather than replacing it, so the size is still obvious to anyone who does not know your codes.

How are stickers matched to your size run?

You give us the size breakdown per design, say 10 small, 15 medium, 15 large and 10 extra large, and each bag is labelled for the garment it holds. When the bags are ordered with your clothing, the sticker goes on as each garment is folded and bagged at the factory, so the label and the contents cannot drift apart. For bags only, send the breakdown so the stickers match it, and the quote confirms how they are supplied.

Do stockists need barcodes on garment bags?

Many do, especially larger retailers and online marketplaces that scan every unit at goods-in. The barcode number belongs to your brand, not to the bag maker. In most markets it comes from membership of GS1, the organisation that issues retail barcode numbers, and marketplaces such as Amazon may ask for their own label code instead. Ask each stockist for its packaging requirements before ordering, then send the codes and layout with your enquiry so the label content is confirmed in the quote. What has to be on the garment for Amazon sets out that side in detail.

Labels beyond the bag

The bag sticker is one layer of labelling. Woven neck labels, care labels and hang tags sit under our labels and packaging service. On a peg display, the size sticker works together with the punched hole, as covered in hang hole bags for retail.

Sending your label details

Include your logo, the size breakdown per design, any colour codes or SKUs, barcode numbers if a stockist needs them, and the delivery country and date. Pricing usually comes back within hours on a working day. The size-stickered polythene bag range has the full specification, and the complete printed bag guide covers sizing and the minimum.

FAQ

Quick Answers

Common questions about packaging — answered.

A size sticker for a clothing bag usually shows the garment size in large, simple characters, such as S, M, L or XL, so it can be read at a glance across a stockroom shelf. Some brands add a colour or style reference. Velocity Wear matches the stickers to your size run, so each bag's label agrees with the garment inside.

Garment bags can carry barcode labels where a stockist or marketplace scans items at goods-in. The barcode numbers are the brand's own, usually from GS1 membership or a marketplace's labelling scheme. Send the codes and the label layout with your Velocity Wear enquiry, and the label content is confirmed in the quote.

An SKU sticker on clothing packaging carries the stock keeping unit code for one exact item, such as a particular style, colour and size. Warehouses that pick by code rather than by eye use it to find the right garment quickly. It can sit alongside a simple size sticker on the bag face.

Size stickers on the outside of the bag let staff and customers find the right size without opening, refolding and resealing anything. That keeps garments neat in the stockroom and on the shop floor, speeds up picking in a warehouse and reduces wrong-size orders, which would otherwise come back as returns.
