Clothing Packaging Guide: Polybags, Mailers and Boxes

Clothing packaging protects garments between the factory and the customer, and it is also the first physical thing a buyer touches. This guide explains the three layers of garment packing, compares the common materials, covers labelling and safety basics, and shows how to specify packaging in your tech pack so the factory packs exactly what you intended.

What Clothing Packaging Includes

Clothing packaging is everything that surrounds a garment from the moment it leaves the production line until the customer opens it. It is not one item but three layers that each do a different job: the unit pack around a single garment, the inner presentation such as tissue and tags, and the outer carton that moves a quantity of garments by road, sea or air. A brand that treats these as separate decisions usually ends up with fewer damaged goods and fewer surprises at the warehouse.

The factory packs the garments according to your instructions, which means packaging is specified in the same way as fabric or trims: in writing, with a drawing, and approved on a sample. If you do not specify it, the factory will use its default, and that default may not suit how you sell.

3 layersUnit pack, inner presentation and outer carton
Folded sizeThe folded garment dimensions that set the bag or box size
Ratio packA carton holding a mix of sizes in a set ratio
Solid packA carton holding a single size

Those terms appear in almost every packing list. The sections below take each layer in turn and then cover the paperwork that travels with it.

The Three Layers of Garment Packing

Each layer of clothing packaging has a specific job, and the right material depends on how the garment is sold and shipped. A wholesale order for a retailer needs robust cartons and clear labelling; a direct-to-customer brand needs presentation and a package that survives postal handling.

The three layers of clothing packaging

LayerPurposeTypical materialsWho handles it
Unit packKeeps one garment clean, flat and protectedPolybag, paper bag, tissue wrap, mailer bagFactory packing line
Inner presentationBrand experience and informationTissue paper, hang tags, stickers, care and size labels, insertsFactory or fulfilment partner
Outer cartonProtects many garments in transitCorrugated cardboard cartons, with strapping or tapeFactory, then freight forwarder
Customer shipping packDelivers an online orderMailer bag, small box, padded envelopeBrand or fulfilment partner

A general structure. Wholesale-only brands may not need the customer shipping pack, and direct-to-customer brands may add their own.

Many brands let the factory handle the first three layers and add the customer shipping pack in the UK. Our guide to the garment production process shows where packing sits at the end of production, after finishing and inspection.

Polybags, Mailers and Boxes: Material Comparison

Choosing a material for clothing packaging means balancing protection, cost, appearance and environmental impact. There is no perfect option, and each material carries trade-offs that a brand should understand before it makes claims about the packaging.

Common packaging materials compared

MaterialStrengthsLimitsNotes
Standard polybag (LDPE)Clear, cheap, light and protective against dust and moistureSingle-use plastic; recycling access variesStandard for garment unit packing; carry a suffocation warning
Recycled-content polybagUses recycled plastic; similar performanceQuality and clarity can vary; claims need evidenceAsk the supplier for documentation of the recycled content
Paper bag or wrapPlastic free, good presentationWeak when wet; less barrier protectionSuits dry, short-transit use
Compostable filmMarketed as compostableOften needs industrial composting, not home or general wasteCheck the standard it claims and how a customer should dispose of it
Cardboard box or cartonStrong, stackable, recyclable in most paper streamsHeavier and bulkier than bagsLook for paper from responsibly managed forests, such as FSC certified board
Padded or mailer envelopeLight and protective for postingMixed materials can be hard to recycleCheck the material and disposal advice

Qualitative comparison. Properties vary by supplier and specification; verify any environmental claim with documents.

Plastic is not automatically the worst choice, because a thin bag that prevents a damaged garment saves the much larger footprint of the garment itself. At the same time, claims such as biodegradable or eco-friendly packaging need evidence and careful wording. Our guide to sustainable packaging for clothing brands goes deeper into this.

Polybag Safety and Warnings

Thin plastic bags can be a suffocation risk for babies and young children, and printing a warning on the polybag is standard practice in the clothing trade. The wording and requirements depend on the market and the product, so check the current rules for the country you sell in and ask your factory how it applies the warning.

Check the current requirements

Suffocation warnings, bag thickness and ventilation holes for children’s products depend on the market and on the product type. This guide is general information, so confirm the current UK requirements with Trading Standards guidance or a compliance adviser before you order printed bags.

Printing a warning on the bag is simple when you plan it early and awkward when you add it later. Include the wording and its position in your packaging specification, and ask the factory to confirm the bag artwork on a proof before they print a full run.

Sizing the Pack: Folding and Fit

Clothing packaging should fit the folded garment, not the other way round. A bag that is too large lets the garment move and crease; one that is too small strains the seams and can split. The rule is to decide the fold first, measure the folded garment, and then choose a bag or box a small allowance larger than that.

Typical folded dimensions of common garments

Approximate longest side when folded

T-shirt (folded flat)25–35 cm
Hoodie (folded flat)30–45 cm
Jeans (folded)25–40 cm
Shirt (folded, boxed style)25–35 cm

Illustrative typical ranges for adult garments by longest side, varying widely with size, fabric weight and folding method. Measure your own sample.

Heavier fabrics such as fleece and denim fold thicker, so a hoodie needs a deeper bag than a tee. Our guide to jeans packaging, folding and labelling shows how this works for denim, including the labels that sit on the folded pack.

Cartons, Ratio Packs and Shipping Marks

The outer carton is the part of clothing packaging that the freight forwarder, customs and your warehouse actually see. It has to protect the garments, but it also has to carry information so that the right goods arrive in the right place. Cartons are usually labelled with purchase order, style, colour, size breakdown, carton number and weight. Size information on the pack should match the size labels in the garment, which is why it helps to settle your size range early, as set out in our clothing size chart UK guide.

From packed garment to shipped carton

  1. 1Fold and bagEach garment is folded to the agreed fold and placed in its unit pack.
  2. 2Add inserts and tagsTags, stickers, size cards and any tissue go in or on the pack.
  3. 3Pack the cartonUnits are packed as a solid pack or a size ratio, as the packing list says.
  4. 4Mark and labelEach carton is labelled with PO, style, colour, sizes, carton number and weight.
  5. 5Seal and palletiseCartons are sealed, sometimes strapped, then loaded for shipment.

A general sequence; exact labelling is set by the buyer, the retailer or the freight forwarder.

The choice between a solid pack and a ratio pack affects how the goods are received, so it is worth settling before the packing list is written.

Solid pack vs ratio pack

OptionWhat is in the cartonBest forWatch out for
Solid packOne size and colour per cartonWarehouses that pick by size; easy to countNeeds more cartons if sizes are very mixed
Ratio packA set mix of sizes in each cartonWholesale buyers delivering assorted sizes to shopsA mistake in the ratio affects every carton

Choose the pack type that matches how your warehouse or retailer receives goods.

Agree the carton size and weight limits with your forwarder before production so cartons can be handled without special equipment. A packing list that matches the physical cartons also makes customs and receiving much smoother.

Branding, Unboxing and Honest Environmental Claims

Packaging is also a marketing surface, and brands often want something more distinctive than a plain clear bag. Printed tissue, branded stickers, a paper band or a rigid gift box can all lift the first impression, but each one adds cost, weight and another item to source, store and pack. Decide which touches matter to your customer and which are decoration for its own sake.

Environmental claims on packaging need the same care as claims on garments. Words such as recyclable, recycled, compostable and plastic free have specific meanings, and a claim is only as good as the documents behind it. Ask suppliers for the material specification and any certificate for recycled content or forest certification, state exactly what the pack is made from, and give customers disposal instructions that match what local services can actually process.

  • Recyclable means the material can be recycled where the customer lives, not just in theory.
  • Recycled content should be stated as what the supplier can document.
  • Compostable needs the standard and the type of composting facility to be named.
  • Right-sizing the pack to the garment is often the most practical way to cut material use.

The simplest improvement for many brands is not a new material at all but a pack of the right size, with fewer layers, that protects the garment and arrives intact.

How to Specify Clothing Packaging in Your Tech Pack

A clear packaging specification belongs in the tech pack alongside the fabric and trims. It should describe what goes on each garment, how it is folded, what bag or box is used and how cartons are packed. The more precise the instructions, the fewer corrections will be needed after production.

Packaging specification checklist

  • Fold method, with a photo or drawing of the folded garment
  • Unit pack material, size and the exact warning wording and position if printing is needed
  • Inserts: tissue, stickers, hang tags, care cards or size cards, with placement
  • Barcode or SKU label placement on the bag or garment
  • Carton type, strength and maximum weight
  • Packing method: solid or ratio, with the size breakdown
  • Carton marking details: PO number, style, colour, size and carton number
  • Any sustainability claim, with the document that supports it

Tailor the list to your product. Children’s products and retailer programmes may add further requirements.

Our tech pack guide explains where to put this, and the labels and tags that sit on the finished pack are covered in the guides on hang tags and custom clothing labels.

Common Packaging Mistakes

Most packing problems are predictable. They tend to come from unclear instructions, packaging chosen before the garment is final, or green claims that are not backed by paperwork. Knowing them in advance helps you avoid them.

  • Ordering bags before the folded garment size is confirmed on a sample.
  • Leaving out the suffocation warning, or placing it where it is hidden by a fold.
  • Using ratio packs without a clear size breakdown on the carton label.
  • Labelling packaging as compostable or recyclable without checking how customers can dispose of it.
  • Designing a premium unboxing that does not survive post and courier handling.

Inspect packing during final inspection, as well as the garments. The checks in our AQL inspection guide can be extended to cover bag condition, labels and carton contents.

How Ruhrose Approaches Packaging

Ruhrose develops hoodies, jersey, denim and woven casualwear for UK buyers, with production in Bangladesh. We pack garments according to the instructions in the tech pack, and we check fold, bag, labels and carton marking on the sample before bulk. We do not quote packaging prices here because they depend on the materials and quantity. If you are designing a printed garment alongside its packaging, how to design a t shirt for production covers the artwork side.

FAQs

Most brands use a polybag or paper wrap for each garment, hang tags or labels for information, and corrugated cartons for shipping. Direct-to-customer brands often add a mailer bag or small box. The right mix depends on how the product is sold and shipped.
Printing a suffocation warning on polybags is standard practice, especially for products that may be used by children. Requirements depend on the market and product, so check current UK guidance and ask your factory how it applies the warning before ordering bags.
It can be, but compostable film often needs industrial composting facilities that many customers cannot access. Check which standard the packaging meets and how it should be disposed of, and state that clearly rather than using broad claims such as eco-friendly.
A ratio pack is a carton containing a set mix of sizes, for example one of each size in a defined proportion, so a retailer can send assorted sizes straight to shops. A solid pack holds a single size. Choose the one that matches your warehouse or retailer needs.
Fold the garment as it will be sold, measure the folded dimensions on an approved sample and choose a bag slightly larger than the fold. Heavier fabrics such as fleece and denim need more depth, so test on the real garment rather than relying on a general size.
Put them in the tech pack alongside fabric and trims, with a fold drawing or photo, bag specification, inserts, barcode placement and carton marking. Approve the packed sample before bulk so the factory packs the whole order the same way.
