Description
Executive Summary: This large diaper bag is a made-to-order OEM/ODM convertible nappy bag from JUNYUAN BAGS, a bag manufacturer established on 2014-08-22 producing through affiliated and partner factories in Fujian, China. It converts between a 26 L backpack, a shoulder tote and a 78 x 40 cm flat bassinet in three moves, using a lightweight grey 300D twill shell and a zip-out 2.2 kg internal frame. MOQ is 500 pieces per style and colour, sampling 6-10 business days, production 35-50 days, AQL 2.5 major / 4.0 minor inspection and a 12-month warranty.
The bassinet conversion is the differentiator: the front panel unzips to a full 78 x 40 cm lie-flat surface with 40 mm raised sides, which gives a changing or rest surface without carrying a second mat. Packed weight is 1.08 kg empty and 26 L, so a full day kit with two feeds lands near 5 kg on the strap.

What a convertible diaper bag with bassinet is for
Most large diaper bags add volume; this one adds a surface. The front panel unzips and folds out into a 78 x 40 cm lie-flat area with 40 mm raised sides, which serves as a changing mat on a bench or a rest surface on a floor where a baby cannot be put down on the bag itself.
The conversion runs in three moves — unclip the two side anchors, unzip the perimeter, fold the panel out — and takes about fifteen seconds with one hand, which is the test we design to. It reverses just as quickly, so the bag does not stay in bassinet mode for the rest of the trip.
- Three-mode carry: 26 L backpack, shoulder tote, and 78 x 40 cm lie-flat bassinet.
- 40 mm raised sides on the bassinet surface so a baby cannot roll off a bench.
- Zip-out 2.2 kg internal frame keeps the bassinet panel flat under load.
- Lightweight grey 300D twill shell at 1.08 kg empty — about 300 g under a 600D equivalent.
- Wipe-clean 210D lining with a TPU-lined wet pocket and two insulated sleeves.

Specification
The specification below is the stock build. The bassinet panel is the part that cannot be changed without retooling, so buyers should treat its 78 x 40 cm size and 40 mm side height as fixed and customise around it.

How the bassinet conversion is engineered
The lie-flat surface is not a mat laid on top of the bag. It is the bag front panel itself, backed by a zip-out frame of six 6 mm glass-fibre rods that keeps the surface flat when a 4 kg load sits in the middle. Without the frame the panel sags about 35 mm at the centre, which is why the frame is not an optional part.
The two side anchors are 25 mm acetal buckles rated to 40 kg each. They carry the load when the bag is used as a tote with the bassinet deployed, so the perimeter zip is never the only thing holding the panel.
- Six 6 mm glass-fibre rods in a zip-out frame; panel sag under 8 mm with a 4 kg centre load.
- Two 25 mm acetal side anchors rated 40 kg each, load-bearing in tote mode.
- No. 8 perimeter zip with a double pull so the panel opens from either end.
- 40 mm raised sides with 12 mm foam, bound seams.
- Frame removes completely so the bag can be washed as a soft bag.
Pocket layout in bag mode
With the panel closed the bag runs as a 26 L day bag. The layout below is what ships at 500 pieces and what buyers amend before sampling.
| Size | Intended contents | |
|---|---|---|
| Front zip pocket | 30 x 18 cm | Nappies, 6-8 units |
| Two insulated sleeves | 12 x 24 cm each | 250 ml bottles |
| TPU wet pocket | 26 x 20 cm | Soiled clothing, damp cloths |
| Rear security pocket | 22 x 15 cm | Phone, cards, keys |
| Two side slip pockets | 13 x 18 cm | Wipes pack, sanitiser |
| Bassinet storage sleeve | 30 x 22 cm | Folds into the closed panel |
| Interior divider | 32 x 20 cm | Spare clothes, muslin |

OEM/ODM customisation options
The grey 300D twill is the standard because it keeps the bag light, and weight is the first complaint on convertible bags. Buyers wanting a heavier hand feel can move to 600D at about 300 g more per bag, which is a finish change and stays inside the MOQ.
| Feature | Standard | Custom range |
|---|---|---|
| Shell fabric | 300D twill polyester | 600D poly, RPET 300D, PU leather panels |
| Colour | Lightweight grey | Pantone match, 300 m minimum per colour |
| Logo | Woven label | Embroidery, rubber patch, heat transfer, metal plate |
| Bassinet size | 78 x 40 cm, 40 mm sides | Fixed — retooling required to change |
| Frame | 6 rod glass-fibre | 4 rod lighter build on request |
| Packaging | Polybag | Retail box, hang tag, FNSKU labelling |
| Volume pricing | 500-1,999 pcs | Tiered from 2,000 pcs, quoted per programme |
Sampling, production and inspection
A convertible bag is sampled twice as often as a fixed one, because the conversion has to be tested by hand. We quote 6-10 business days and normally use 10 on this pattern, with a video of the conversion included in the sample pack.
| Stage | Duration | What happens |
|---|---|---|
| Artwork and spec sign-off | 2-3 business days | Tech pack, frame drawing, Pantone locked |
| Sample making | 8-10 business days | Includes conversion video and load photos |
| Sample approval | 3-5 days | Courier transit excluded |
| Material sourcing | 7-10 days | Runs parallel with approval |
| Cutting and sewing | 24-32 days | 500-2,000 pcs per line |
| Final inspection | 1-2 days | AQL 2.5 major / 4.0 minor, level II |
| Packing and handover | 2-3 days | Carton marking, loading photos |
| Total production | 35-50 days | Measured from sample approval |
Carton data and shipping profile
Convertible bags are bulky when packed, so the carton plan uses a 58 x 44 x 40 cm box at 16 units. A 500-piece launch is 32 cartons, roughly one and a half pallets.
- 1 pc per polybag, 16 pcs per 58 x 44 x 40 cm carton.
- Carton gross weight 19.2 kg; 0.102 CBM per carton.
- A 20 GP holds about 5,400 pcs; a 40 HQ about 13,000 pcs.
- Frame ships inside the bag, so no separate component carton is needed.
- Retail box option adds 0.6 kg per carton and changes the box to 60 x 46 x 42 cm.
Why this convertible pattern is specified by nursery brands
JUNYUAN BAGS has produced baby and nursery bags since 2014-08-22 through affiliated and partner factories, and this bag repeats because the bassinet conversion is documented with a frame drawing that does not change between orders. Buyers comparing formats look at the large diaper bag tote for a simpler fixed body, or the PU leather diaper bag backpack for a leather-look finish. The full range is in our diaper bag category.
Frequently Asked Questions
- What is a convertible diaper bag with bassinet?
- It is a diaper bag whose front panel unzips into a flat, raised-edge surface that works as a changing mat or a place to set a baby down. On this pattern the surface is 78 x 40 cm with 40 mm raised sides, and the bag converts in three moves in about fifteen seconds.
- How big is the bassinet surface and is it safe for a baby to lie on?
- 78 x 40 cm with 40 mm raised sides, flat to within 8 mm under a 4 kg centre load because of the six-rod glass-fibre frame. It is a changing and rest surface on a floor or bench, not a substitute for a certified sleep cot, and it is not intended for unsupervised sleep.
- Why is the bag made from 300D twill instead of 600D?
- Weight. A convertible bag carries a frame as well as fabric, so the 300D twill keeps the empty weight at 1.08 kg — about 300 g less than the same bag in 600D. Buyers who prefer a heavier hand feel can specify 600D as a finish change inside the same 500-piece MOQ.
- Can the bag be used as a backpack and a tote?
- Yes. Padded 50 mm backpack straps tuck into a rear channel, and a 30 mm tote handle takes over. In tote mode the bassinet panel is carried by two 25 mm acetal side anchors rated at 40 kg each, so the perimeter zip is never the only load path.
- What is the MOQ and can the bassinet size be changed?
- MOQ is 500 pieces per style and colour. The 78 x 40 cm bassinet size is fixed because the panel is cut on a dedicated die and the frame is jig-built; changing it needs retooling and a separate quotation. Colour, logo, lining and packaging all change inside the standard MOQ.
- How long do sampling and production take?
- Sampling is 8-10 business days on this pattern because the conversion is tested by hand and a video is included with the sample. Mass production is 35-50 days from sample approval. Repeat orders on the same frame and fabric lot run 30-38 days.
- How much does the bag hold in bag mode?
- 26 L across seven pocket groups, including a 30 x 18 cm nappy pocket, two 12 x 24 cm insulated sleeves and a 26 x 20 cm TPU wet pocket. The rated load is 7 kg, which covers a full day kit for one child with two feeds and a change of clothes.
- What does the 12-month warranty cover?
- Stitching, zips, the frame, side anchors, strap anchors and lining delamination for 12 months from delivery. Claims need the order number plus photos of the defect and carton label; verified defects are credited or replaced in the next run, with 2 per cent of each order retained as reference samples for 90 days.
