Double-Layer Oxford Fabric Briefcase Wholesale: A 2026 B2B Sourcing Guide to 42 x 32 x 10 cm Large-Capacity Laptop Bags and Document Bags

1. The Bag That Has to Carry Both Halves of a Working Day

A briefcase is asked to do two jobs at once. It has to protect a laptop, which means a padded sleeve the device actually fits into. It also has to carry the paper side of a working day — quotations, contracts, a set of A4 documents — which means flat space that does not compress the device when the bag is closed.

Most bags solve one and compromise the other. A slim sleeve protects the laptop and has nowhere to put the paperwork. A document bag carries the papers and leaves the device unprotected. This guide deals with the middle position: a double-layer Oxford fabric professional briefcase at 42 x 32 x 10 cm, with a padded laptop sleeve and the storage to keep devices and documents apart.

It is written for buyers who purchase in quantity — distributors adding a line, brands buying OEM, online sellers who need a stable listing, and internal buyers equipping a team. It covers what the bag is, why the double-layer structure is the buying argument, how it is carried, what fits, and the commercial terms that decide whether a quotation is worth requesting.

2. What This Briefcase Is, and Who Buys It

The format is simple to describe. It is a horizontal, large-capacity briefcase measuring 42 x 32 x 10 cm, built from Oxford fabric with a nylon lining. Two webbing handles sit at the top, and the bag also ships with a detachable strap, so it can be carried by hand or worn as a shoulder bag. Inside, a padded laptop sleeve takes a device up to 15.6 inches, and multi-pockets separate the device from documents and smaller items. There is a zip pocket on the front face for the things you need without opening the bag.

The 10 cm depth is the part that changes how the bag is used. A flat document bag can only carry paper and a laptop side by side. Ten centimetres of depth is enough for a padded sleeve, a second layer for documents, and the pockets that keep a charger, a phone and a passport from ending up in the same place. That is the difference between a bag that carries a laptop and a bag that carries a working day, and the reason the buying profiles below all land on the same specification.

Buyer What they are buying for What decides the order
Corporate office and staff issue One briefcase for teams that move between sites and meetings A single specification, a stable unit cost and a clean logo position
Stationery and office-supply distributors A catalogue line that sits beside folders and paper goods Colour range, carton configuration and repeatability
Bag brands buying OEM A finished construction they can re-specify under their own label Whether fabric, colour, logo and packing can change per order
Online sellers A laptop bag and document bag listing with defensible claims Consistency between units, so listing photos and copy stay accurate
Meeting, training and event buyers A bag that replaces both a folder and a laptop sleeve Whether devices and A4 documents can travel in one pass

3. Double-Layer Structure: Why the Capacity Is the Buying Argument

The phrase "double-layer" is doing real work here. It describes a bag with a padded laptop sleeve on one side and a separate storage layer behind it, so a device and a set of documents never press against each other. Buyers who have handled a single-compartment bag know the failure mode: the laptop is fine on Monday and has a pressure mark on the screen by Friday, because the paperwork has been leaning on it all week.

The structure also decides how much the bag can do without getting deeper. Ten centimetres is a deliberate ceiling — enough for the sleeve, the document layer and the multi-pockets, not so much that the bag stops fitting under a seat or on a lap. For a distributor, that ratio matters commercially: a briefcase that is genuinely large capacity but still carries like a briefcase is easier to sell than one that is simply bigger.

For a bulk order, the practical questions about structure are the ones worth putting in writing before sampling. Which layer is padded and how thick the padding is. Whether the sleeve is fixed or removable. How the pockets are laid out, and whether the front pocket is zipped. Those answers, not the marketing description, determine whether a second order matches the first.

Consideration Double-layer briefcase, 42 x 32 x 10 cm Single-compartment laptop sleeve Rigid hard-shell case
Device protection Padded sleeve, separate from documents Padding present, but documents share the space Rigid shell, fully protective
Documents and files Own layer, so nothing presses on the device Compressed against the device Limited flat space
Capacity in daily use Device, documents, charger, phone, passport Device and a thin folder Device and accessories only
Carry options Webbing handles plus a detachable strap Usually a sleeve or a single handle Handle and often a trolley sleeve
Carton efficiency Fills a carton with 15 units at a fixed footprint Packs very tightly Wastes void space in every carton
Best suited to Meetings, site visits, daily office commute Minimal carry days Equipment that needs rigid protection

4. Two Ways to Carry It: Handles or Detachable Strap

The bag gives the buyer a choice rather than a fixed carry system. Two webbing handles sit at the mouth for the short leg — office to car, car to meeting room — and the detachable strap turns it into a shoulder bag for the longer one. Detachable matters for a bulk order, because a strap can be left in the carton for a staff-issue programme where nobody wants one, and fitted for a distributor version that sells on carry comfort.

For the office commute, the two modes cover the whole trip. Carried by hand through a lobby, on the shoulder on a crowded platform, set down flat at the desk. The front zip pocket keeps a phone, keys or a travel card reachable without opening the main compartment, which is the detail that decides whether a bag gets used every day or only when it is unavoidable.

Moment in the trip Carry mode Why it works
Out of the office Two webbing handles Nothing to adjust, nothing to swing
Crowded platform or train Detachable strap on the shoulder Keeps one hand free for a phone or a rail
Walking into a meeting room By hand, then set down Sits upright on the table without being unpacked
During the meeting Open on the table Documents out of their own layer, device left in the sleeve
Handing over a document Front zip pocket or the document layer Fewer steps than unbuckling a flap
End of the day Strap stowed or removed Reverts to a flat-profile bag for storage

5. What Fits Inside: A 15.6-Inch Laptop and A4 Documents

The padded sleeve takes a laptop up to 15.6 inches, and the document layer behind it holds A4 paperwork flat. Multi-pockets then separate the smaller items — a charger, a cable, a phone, cards, a passport — so that reaching for one thing does not mean unpacking the bag.

Two numbers explain the capacity. The internal width of 42 cm clears a 15.6-inch device with margin, and the 10 cm depth is what makes the second layer possible in the first place. Because the sleeve is padded and the document layer sits behind it rather than in front, a full set of papers does not press on the screen.

The result is one bag for a working day that mixes analogue and digital. Folders and printed documents go flat, the device goes into the padded sleeve, and the accessories go into their own pockets. That is the difference between a laptop document bag and a plain sleeve: the sleeve protects the device, the bag protects the device and the paperwork around it. Buyers who want to check a specific laptop against the interior before committing to a quantity should do that at the sample stage, because device fit is the one specification a photograph cannot prove.

What goes in Where it sits Note for the buyer
Laptop up to 15.6 inches Padded sleeve Confirm your exact model against a sample
A4 documents and folders Document layer behind the sleeve Flat, so nothing presses on the screen
Charger and cable Multi-pockets Separated, so nothing scratches the device
Phone, cards, passport Front zip pocket or inner pockets Reachable without opening the main compartment
Power bank Pocket beside the device Same layer as the accessories, not the papers
Keys Front zip pocket Outside access at a door or a ticket gate

6. The Colour Range and How It Gets Used

The listed version is the blue briefcase, and blue is the colour that does most of the selling: it reads as business equipment, it matches most corporate palettes, and it hides handling marks on a bag that is carried daily. The range is completed by orange and black, which are used for different jobs rather than as decoration.

Black is the neutral choice when a staff list is mixed and nobody wants to be identified by a colour. Orange is the deliberate one — for a department, a site, a shift or an event where the bag has to be recognisable from across a room. Three colours from one construction also means one photograph set and three catalogue lines for a distributor, and a starting palette rather than a fixed colour for a brand buying OEM.

Colour Natural use Why buyers pick it
Blue (listed version) Corporate programmes, distributor catalogues, online listing Pairs with most corporate palettes and reads as business equipment
Black General staff issue, everyday use Neutral, no colour matching to a brand, hides handling marks
Orange Department or site coding, events, training kits Identifiable at a distance without printing a label
Any of the three Custom programmes The palette can be re-specified per order

8. Custom Options for Your Market

A briefcase like this is a good candidate for custom work because the construction is already fixed: the work is specification, not development. For a bulk order, five variables are worth deciding before a sample is made.

Variable What can change What it is used for
Colour Body specified per order from the range Matching a corporate palette or a market's preference
Fabric Alternative Oxford weights and finishes in the same construction Adjusting hand feel and price point for a market
Custom logo A logo applied to the front face or a label position Staff programmes, distributor catalogues, own-label ranges
Branding on the strap Logo on the detachable strap or its hardware Completing a branded set when the strap is fitted
Packing Dust bag, polybag and carton configuration Retail presentation, warehouse handling, event hand-out

This is where an OEM order and a wholesale order stop looking alike: wholesale takes the bag as it is and buys it by the hundred, while OEM changes one or more of the variables above. The front face is a clean panel for a custom logo, which means a mark can be applied without wrapping it around a curve or splitting it across a closure.

Approach What changes Typical buyer
Wholesale as-is Nothing; the bag is ordered in blue, orange or black Distributors and online sellers
Light customisation Logo added, colour chosen from the range Corporate staff programmes
Full OEM Colour, fabric, logo, branding and packing all specified Bag brands and own-label ranges
ODM support Construction adjusted with our team before sampling Buyers who need a variant, not a copy

9. Compliance, Inspection and What the Buyer Receives

Documentation is usually the last item discussed and the first one that stops a shipment. The two markets that matter most for this format are the United States and the European Union, and the paperwork below is prepared per destination rather than issued as a single generic pack.

Item Standard When it is prepared
CPSIA documentation United States consumer product safety requirements With the order, per destination market
REACH documentation European Union chemical compliance With the order, per destination market
Inspection standard AQL 2.5 Applied to the bulk order at the agreed inspection point
Sampling approval Sample agreed before bulk production First step of every order

Two notes for buyers comparing suppliers. Ask any supplier what documentation is issued by default and what must be requested separately, because that answer changes the landed cost. And fix the inspection point in writing before production starts — AQL 2.5 is the standard, but the moment of inspection is a commercial decision.

10. MOQ, Sampling and Lead Time

Term Value
Minimum order quantity 500 pcs per style
Sampling 7-10 days
Bulk production 30 days
Packing 1 pc per dust bag plus polybag, 15 pcs per carton
Carton dimensions 65 x 45 x 35 cm
Documentation CPSIA and REACH, per destination market
Inspection AQL 2.5

The packing configuration is worth reading alongside the price, because it is where the landed cost is decided. Fifteen units per carton at 65 x 45 x 35 cm gives a fixed, calculable cube per hundred pieces, which is what a distributor needs in order to quote storage and freight without guessing. If a deadline is fixed, the sequence that works is sample first, approval, then production.

11. Who We Are

Driulug is a manufacturer based in Chang'an, Dongguan, making bags since 2008 and shipping to more than 30 countries. Our own production line is the reason the sampling window is short: the people who will run the order are the people who answer the construction questions. That is the practical difference between buying from a manufacturer and buying from a reseller.

For buyers who want to see this briefcase alongside the rest of the business range, our Business Laptop Bags collection is the right starting point, and the Document Organizers and File Bags collection covers the document-storage side of the catalogue. If you already buy a laptop document bag elsewhere, this format is worth comparing on layer structure and carton cube rather than on price per piece alone.

12. FAQ for Briefcase Buyers

What is the minimum order quantity for this briefcase? 500 pieces per style. It applies to wholesale and OEM orders alike, and it does not change by colour.

Does it fit a 15.6-inch laptop? The padded sleeve is built for devices up to 15.6 inches. Device fit is the one specification worth confirming against a sample rather than a photograph, so check your model with us before committing to a quantity.

How does the double-layer structure work? A padded laptop sleeve sits on one side and a separate layer behind it takes documents and folders, so the paperwork never presses on the device. Multi-pockets keep a charger, a phone and cards out of both. That is the whole case for a laptop document bag with two layers rather than one.

Can the bag be carried on the shoulder? Yes. It comes with two webbing handles and a detachable strap, so it can be carried by hand or as a shoulder bag, and the strap can be left off a staff-issue order entirely.

How long does sampling take, and how long is bulk production? Sampling runs in 7-10 days from the point the specification is agreed. Bulk production is 30 days from sample approval.

How is it packed for shipment? One piece per dust bag plus polybag, 15 pieces per carton, in a carton of 65 x 45 x 35 cm. If you need a different carton configuration, raise it with the enquiry.

Which compliance documents come with a bulk order? CPSIA documentation for the United States and REACH documentation for the European Union, prepared per destination market.

Can you apply our logo? Yes. The front face is a clean panel and the detachable strap can also carry branding. Logo position and application method are confirmed at sampling.

13. Honesty Notes

A buyer should know exactly which parts of the specification come from the product record and which are settled at the sample stage.

Item Status
Dimensions, structure, material and packing Taken from the product record
Laptop fit Stated as up to 15.6 inches; confirm your exact model against a sample
Padding thickness of the sleeve Confirmed against an order sample
Exact pocket count and layout Confirmed against an order sample
Fabric weight and finish within the Oxford range Confirmed per order
Price Quoted against quantity and specification
Custom colour outside the range Quoted as an OEM specification

14. Next Step

If you are buying briefcases for a staff programme, a distributor catalogue or your own listing, send the quantity, the destination market and the colours you need, and we will quote against the specification rather than against a range.

One question worth answering before you write the enquiry: is this replacing a folder and a laptop sleeve, or replacing a full travel case? The answer decides whether the 15.6-inch sleeve and the document layer are the right combination for your market.
