Hanger bags — also called hanging poly bags, garment bags or suit covers — differ from flat bags in one decisive way: the bag hangs on a rail with the garment inside, carries the whole weight of the garment on its own, and doubles as the display pack on the shop floor. Pick the wrong hole position or thickness and the top edge tears, the garment slips off, and you are looking at returns and re-orders.
This guide works through seven parts — when hanging beats flat packing, four common bag types, sizing back from the garment, hook holes and load bearing, material, thickness and anti-fog, printing and export marking, and a sampling check — and closes with a specification list you can copy straight into a request for quotation.
1. Hanging or Flat: When You Actually Need a Hanger Bag
- Straight to the rail: for hanging displays the clear bag is the display pack itself, which saves the store a re-packing step
- Crease-sensitive outerwear: suits, coats and down jackets travel better hanging, with far fewer fold and pressure marks
- Mixed containers and air freight: hanging garments fit a dedicated hanging container or a rail inside a carton, but they occupy more volume than flat packing — price the freight gap first
- Where hanging is a waste: T-shirts, underwear, socks and towels pack flatter and cheaper; forcing them into hanger bags only raises cost
2. Four Common Hanger Bag Types
| Bag type | Typical use | Advantage | Watch out for |
|---|---|---|---|
| Punched clear hanger bag (open) | Single tops and dresses for store delivery | Lowest cost, garment fully visible | Only basic dust protection; add an outer bag for long transit |
| Self-adhesive seal hanger bag | E-commerce shipping and single-item hanging | Seals against dust, printable | The adhesive can fail under pressure or humidity — check where it sits |
| Zipped suit cover | Suits, coats and formalwear | Re-openable, best protection, reusable | Highest cost; the zip-to-film joint is the weak point |
| Non-woven dust bag | Made-to-order, gifting and long-term storage | Breathable, opaque to the garment inside, printable all over | Opaque — add a clear window if the style must be checked |
3. Sizing: Working Backwards from the Garment
- Width: shoulder width (or the widest chest point) plus 3–5cm for sleeve bulk and natural drape
- Length: garment length plus 8–12cm; on suits allow for the hanger hook so the hem does not drag on the bag bottom
- Gussets: thick coats and down jackets need a gusseted bag so the film is not stretched into a tight bulge
- Hole position: centred on the top edge, 2–4cm down; when several bags share a rail, stagger the heights so the hangers do not clash
4. Hook Holes and Load: Where Tops Actually Tear
- Hole styles: plain round, eyelet (metal or plastic ring), teardrop and euro-slot; eyelets carry the most load but add cost
- Reinforcement: on heavy bags or garments (coats, down) add a reinforcement patch or welded film at the hole so it does not crack open over time
- Match the hanger: confirm the hook diameter and shape (round or flat) first — too small a hole will not fit, too large slips off
- Where to punch: keep the hole inside the sealed edge zone, never on the seal line itself, or the first tug will split it
5. Material, Thickness and Anti-Fog
- Material: LDPE is soft and tear-resistant, ideal for hanging; HDPE is crisper but brittle and cracks under long hanging; CPE balances clarity and strength for bags that must show the garment
- Thickness: single-item hanger bags usually run 0.025–0.05mm, suit covers 0.05–0.08mm; the right figure depends on garment weight and bag type, so hang a sample when in doubt
- Anti-fog film: cold chain or large day-night temperature swings fog up the inside of the bag; you need a film with anti-fog additive or the garment is no longer visible
- Anti-static and recyclability: static-heavy film attracts dust — very visible on pale garments; for the EU, mark the material and recycling code as local packaging rules require
6. Printing, Marking and Export Requirements
- Where to print: hanger bags are usually printed at the bottom or on the side, keeping the front clear so the garment shows; full-surface printing cuts clarity sharply
- Must-have marks: material and recycling code, the suffocation warning on large bags, barcode or size label, plus origin and importer details required at destination
- Venting: on sealed bags add vent holes so pressure changes in transit do not blow the bag open; keep them clear of the printed area
- Eco options: raise the recycled content or switch to a mono-material recyclable film — EU-bound customers now ask about this as standard
💡 Tip: the real acceptance test for a hanger bag is 24 hours on a rail. Have the supplier hang a fully loaded bag for a day, then inspect the hole edge, the seal and the body for distortion or tearing — good numbers on paper mean nothing if it will not hold.
7. Sampling and Acceptance Checklist
- Fix the bag type and hole position, and supply the hanger hook spec your customer actually uses
- Give shoulder width, garment length and unit weight so the supplier can work out bag width and length
- Hang test: suspend at real weight for 24 hours and inspect the hole edge and seal line
- Confirm print content, position and colour, plus the recycling code and warning wording
- Settle the shipping pack (hanging container, rail in a carton, or folded into cartons) and the lead time before bulk, not after arrival
