800 ml, double-wall vacuum 304 stainless. It is the one with a plain finish that suits corporate branding, a capacity aimed at a full adult portion, with 5 stock colours to choose from. Custom logo from 500 pieces.
The vacuum layer is what makes this work: with almost nothing left to conduct heat away, hot food stays above serving temperature through a working day, and in the larger sizes you can pour in boiling water and raw rice in the morning and open cooked congee at lunch. The inner wall is 304 stainless throughout — the grade matters because lower grades pick up odours and pass them to whatever goes in next. The closure seals inverted, which is the only test that matters for something that travels in a bag.
Also on the buyer’s checklist here: macaron colours, a minimal look, solid colour, heat retention, commuting, outdoor use.
Broken into the parts a buyer actually checks: The 304 liner throughout — the grade decides whether it holds odours, and lower grades do. The colourway photographs well, and in social-led retail that decides whether a listing moves. The closure seals under inversion rather than merely closing, which is the only test that matters for something carried in a bag. Thermal performance holds through a working day rather than fading after the first hour, because the vacuum is drawn properly rather than partially. The interior wipes clean without scrubbing, which matters more on a food container than on a drinks bottle.
Also on the buyer’s checklist here: heat retention, cold retention, degrading, sealing, leak-proof when inverted, porridge, baby food.
What keeps this model on repeat order: the size lands with the widest slice of end users, which is what a retailer cares about more than any single feature; complaints are rare enough that the buyer stops budgeting for replacements; the colours carry the product on social feeds without extra photography spend; mixed-colour containers let them test the range before committing capital to one colour. Worth reading as a checklist rather than a boast — if those reasons do not apply to your channel, a different model in the range probably fits better.
Also cited on repeat orders: acceptance at the end-user level, heat retention, consistency, a leak-proof seal, macaron colours, colourway.
Choosing between them
How TW-1001 compares with the rest of the range
Buyers rarely arrive knowing which model they want — they arrive knowing the brief. This table is the fastest way to check whether TW-1001 is the right answer or whether a sibling fits better. The row highlighted is the one you are looking at. Every model listed runs from 500 pieces per design.
Every model above ships from 500 pieces per design. Mixing several of them in one container is normal — a 20ft container holds roughly 26 m³ of cartons, so a mixed load is planned on carton volume rather than on piece count. Send the full list at enquiry rather than model by model.
Who is buying TW-1001, and what they do with it
A supermarket chain in Malaysia takes this one for office workers, parents with young children and outdoor users. It also goes through a cross-border e-commerce seller; and they picked this model because the colour range lets them mix a container.
Also on the buyer’s checklist here: gifting, stores, office workers, parents, outdoor use, commuting.
What buyers tell us their customers do with it: a commute where there is no microwave at the other end; baby food carried warm rather than reheated; porridge that finishes cooking on the way; soup; a packed meal; camping and days out; shelf retail. If your end use is not on that list, tell us anyway — it usually points at a different model in the range.
Also on the buyer’s checklist here: office workers, commuting, porridge, packed meals, parents, baby food, heat retention, outdoor use, camping, gifting, retail.
Where this model has been pushed: A buyer in Saudi Arabia placed a large single order across mixed colours with their own logo printed timed to a seasonal peak. We ran the line on overtime and moved their batch up the queue, with tighter than usual inspection on the critical spec. and delivered ahead of the agreed date They have reordered 3 times. The reason it is here rather than in a case-study page: this is the kind of run that tells you whether a supplier can handle your peak, not your average.
Also in play on that job: mixed loading, full container, peak season, custom decoration, vacuum, heat retention.
Importers & wholesalers
This model packs 30 per carton (62cm×47cm×53cm for the base size — the full carton table is in the spec above), and that number decides how many pieces fit a 20ft container far more than the FOB price does. What decides your landed cost here is the carton, not the unit price: ask for the container plan before you fix a retail price, because a wide-body jar fills a 20ft on volume long before it hits the weight limit. We quote EXW Yongkang, FOB Ningbo or Shanghai, or DDP door to door, and we will say which of the three costs you least given where you are rather than defaulting to whichever is easiest for us.
Brand owners & private label
On TW-1001 the stock range is 5 colours (purple, blue, green, light green), so a Pantone match is only worth the 1,000-piece run if none of those is close enough. Budget it as three lines, not one: decoration sits inside the unit price, a matched Pantone is its own spray run from 1,000 pieces, and packaging is separate with its own tooling and proofing round. Brands that budget these as a single number are the ones surprised at quotation: decoration sits in the unit price, a matched Pantone is a separate spray run from 1,000 pieces, and a printed colour box carries its own tooling and one proofing round. We sign an NDA before you share artwork, and a shape you tool for stays reserved to you — the same terms we have run with Hallmark since 2017 and with KRAUS for over ten years.
Retail chains
TW-1001 packs 30 per carton, so a 12-store drop lands on a clean carton multiple rather than a split case. Retail-ready means more than a colour box: UPC or EAN printed and scan-tested before the carton is sealed, carton marking to your own packaging manual, and inner counts that match what your DC expects. A barcode that fails at the till becomes a chargeback, and it is entirely preventable at our end: we print and scan-test every UPC or EAN before the carton is sealed. Ask for the retail packaging spec sheet with your first quote — it lists carton dimensions, inner counts and the UPC placement we scan-test before sealing.
Promotional distributors
TW-1001 is a single-capacity line, which is the fastest thing we can turn around when a date is already tight. Work backwards from the in-hands date, not forwards from the order date: 7–10 days for a pre-production sample, about 30 days production after approval, then 30–35 days sea freight to Europe or 25–30 to the US west coast. Production is 30 days after deposit and artwork approval, plus 7–10 days for a printed pre-production sample, plus sea freight — roughly 30–35 days to Europe, 25–30 to the US west coast. Late artwork is normal in this business; a date discovered late is not survivable — artwork approval is what starts the 30-day production clock, not the deposit. Tell us the date at enquiry and we will say honestly whether it is achievable.
Amazon & e-commerce sellers
TW-1001 ships in a 62 cm × 47 cm × 53 cm carton — send us your FBA plan and we will confirm whether that splits cleanly under the dimension cap before you book. FNSKU labels, Prop 65 and suffocation warnings applied here, cartons built to FBA dimension limits, and we can split a shipment across fulfilment centres if you send the plan. Doing it at the factory removes a prep-centre handling fee and about a week of transit on every restock. Watch dimensional weight on this category — the carton is light for its size, so FBA usually bills on volume.
End users & institutions
On TW-1001 laser engraving is the safe call for daily institutional washing. Canteens, schools and site catering wash hard and often, and this category goes through more of it than a drinks bottle because it holds food. Laser engraving costs slightly more up front and removes the complaint entirely: the mark is cut into the steel and reads the same after a season of commercial dishwashing, while printed artwork on a coated body visibly fades.
Failures we hear about from buyers who switch to us
When a buyer changes supplier on this product, it is usually one of the following. We list them because they are checkable before you commit, not after.
✓
Lids that do not lock
The most common complaint we inherit: a container that seeps into a bag once is never bought again. Ask any supplier to run an inverted seal test with liquid in it, not just show you the gasket.
✎
A vacuum that fades
A weak draw passes a same-day test and disappoints two months later. We check vacuum integrity on 100 % of bodies as semi-finished parts — before assembly, before coating — because on a finished branded unit the flaw stays invisible until it becomes your customer’s problem.
⚑
An inner wall that is not really 304
Lower grades rust and hold odours, and food picks that up immediately. Ours is 304 throughout, stated on the invoice.
◷
Coatings that chip
Cheap outer paint scratches through within weeks and the product looks second-hand on a shelf long before it stops working.
Where TW-1001 is actually made
Eight workshops in Yongkang, Zhejiang, running since 1998 — mould development, vacuum welding, injection moulding, spray painting, laser marking, printing, assembly, inspection and packing, all in one building. For TW-1001 the stage worth watching is the vacuum draw and the wide-mouth seal.
A food jar is harder to build than a drinks flask for one reason: the mouth is wide, so the sealing surface is long and the liner has a bigger opening to close around. We draw the vacuum on the liner as a semi-finished part and test it there — before assembly, before coating, before your logo goes on. A weak draw passes a same-day test and fails two months later, and on a finished, printed, shipped jar that flaw is invisible until it is your customer’s problem. The second bench that matters is the inverted seal test: liquid in, lid on, upside down. We run it because a jar that seeps congee into a laptop bag is returned once and never bought again.
We inspect 8% of every batch rather than a fixed sample per shipment. Buyers are welcome on site — eight workshops in Yongkang, Zhejiang, running since 1998, about three hours by road from Ningbo port and two from Hangzhou airport, which makes a factory visit a realistic side trip rather than a separate journey. Ask to see that bench specifically; it is where the difference shows — we check vacuum integrity on 100% of bodies at the semi-finished stage, before assembly and coating, because a micro-leak is undetectable once the jar is built.
Is TW-1001 the right one for your programme?
Importers & wholesalers — A good fit — this one already ships in mixed-colour containers for buyers testing which colours move. Stock colours are purple, blue, green, light green, pink, and 500 pieces per design gets you started rather than 5,000.
Brand owners & private label — Yes. Three separate lines to budget: the logo sits in the unit price, a matched Pantone is its own run at 1,000 pieces, and packaging is third — this model ships in a printed colour box as standard, and anything else is a separate tooling and proofing round.
Retail chains — Currently on shelves through buyers in this channel. Retail-ready colour boxes, printed UPC or EAN, and we scan-test the barcode before the carton is sealed.
Promotional & gifting — One of the stronger uses for this model. Give us the in-hands date at enquiry rather than after artwork approval — we work backwards from it and tell you honestly whether it is achievable.
E-commerce & Amazon sellers — Sold this way already. We can apply FNSKU labels, Prop 65 stickers and suffocation warnings at the factory and ship FBA-ready cartons direct to fulfilment centres.
FAQ
Ordering TW-1001 — common questions
Why TW-1001 rather than another model in this range?▾
This one runs 800 ml, and it is the one with a plain finish that suits corporate branding, the largest capacity in this family, with 5 stock colours to choose from. End users are office workers carrying a hot lunch, commuters, parents carrying baby food and warm porridge, baby and toddler food, outdoor and camping use. Where it stops making sense: any programme where the end user needs something this model was not shaped for. Tell us the use case and we will say so plainly.
How long does TW-1001 keep food hot?▾
At 800 ml, expect around 12 hours with a full fill, less if it is opened repeatedly or only half filled. The double-wall 304 stainless body is the reason: with the air drawn out between the walls there is almost nothing left to conduct heat away. Two habits worth printing on your packaging — rinse with boiling water before filling, and fill it as close to the top as practical.
Which colours can we order TW-1001 in?▾
Stock colours are purple, blue, green, light green, pink — those run from 500 pieces per design. A matched Pantone is a separate spray or resin run and starts at 1,000 pieces. Mixed-colour containers are normal here: several buyers deliberately split a container across colours to see which ones move before committing to one.
How do we brand TW-1001?▾
Silk screen for one to three flats onto a sprayed body, UV digital for full colour, laser for a permanent single-tone mark. If the end user runs it through a commercial dishwasher every evening, engraving is the only method that still looks right after a season.
What is the MOQ, lead time and carton spec for TW-1001?▾
500 pieces gets you started on stock colours. Budget 1,000 if the brand colour has to be exact. Production runs 30 days after deposit and artwork approval, sample in 7–10 days. Packing is 30 pcs per carton at 62cm × 47cm × 53cm. Shipping terms: EXW Yongkang, FOB from Ningbo or Shanghai, or DDP straight to your warehouse.
Is this a vacuum insulated food jar or just double-wall?▾
Vacuum insulated. TW-1001 is a vacuum insulated food jar — two walls of 304 stainless with the air drawn out between them, not simply two walls with air left in. The difference is the whole product: a double-wall body without a vacuum draw feels the same in your hand on day one and goes cold by lunchtime. We test the draw on the liner as a semi-finished part, before assembly and before coating, because on a finished insulated food jar the flaw is invisible until it is your customer’s problem. Ask any supplier at what stage they vacuum-test — the answer tells you a lot.
