This is a die-cut self-locking corrugated mailer with a printed interior and a matching all-paper insert. The outside stays plain kraft for clean, low-cost shipping. The inside opens to full-color branding, a QR code, and printed instructions, while a die-cut paper tray holds each part in its own cavity. It replaces foam and blister trays with recyclable board, so the whole pack goes in the same recycling stream. It is designed for bathroom and sanitary kits such as hand showers, faucets, and fixture sets sold direct to customers.

Why the interior is printed and the exterior stays plain
Printing inside instead of all over the box gives a branded reveal at a lower cost. The kraft exterior takes a simple one-color line print, which is the economical option for a surface that gets handled and labeled in transit. The full-color interior is where the brand moment lives, so the print budget goes to the panels the customer actually opens. A large solid panel, like a full-bleed color background, holds most consistently as a Pantone spot rather than a four-color build, so we recommend a spot for any panel-wide brand color.
A paper insert instead of foam or blister
The insert is die-cut corrugated, not plastic. It nests each part in its own labeled cavity so nothing shifts, and it absorbs handling shock the way an EPE or thermoformed tray would, without adding a second material to separate at disposal. The customer recycles the box and the tray together. For finish-sensitive bathroom hardware, soft paper contact surfaces sit against the part so polished chrome and matte black do not scuff. Our structural team designs the cavity layout to your exact components.
Built for bathroom and sanitary kits
Bathroom hardware is dense, finish-critical, and often shipped as a multi-part kit. This pack handles that. Hand showers, hoses, connectors, brackets, and tools each get a fitted seat, and printed on-box steps replace a loose paper manual. Xiamen and South Fujian are a global kitchen and bath manufacturing cluster, so the structural design, sampling, and material supply for this vertical sit close to where the products are made.
Shipping protection
The mailer ships as a parcel, so it is engineered for parcel handling. E-flute gives a thin, strong wall with a smooth print face, and the self-locking die-cut closure seals without tape and resists tearing on opening. Wall strength is engineered from the kit weight, drop height, and transport mode, then verified on our in-house tester with compression and burst checks. We design to ISTA 3A or Amazon parcel requirements and provide our test data to support certification when your channel requires it.
Eco and compliance
The pack is single-material corrugated, which keeps it curbside recyclable and removes the foam or plastic tray that usually complicates disposal. FSC-certified board and recycled content are available on request. For EU-bound shipments, the single-material paper design lines up with PPWR recyclability and minimization rules taking effect in 2026, which we are glad to review against your destination markets before artwork.
Ordering
Send your product dimensions, target quantity, destination market, and artwork, and we return an engineered dieline, a recommended spec, and a quote. We can ship a blank structural sample or a printed digital proof for your approval before the production run. Production is offset and flexo printing built for export volumes, with no strict minimum, though unit cost drops as quantity rises. Certifications on file include ISO 9001 and 14001, FSC chain of custody, G7, and GMI.
FAQ
What order quantity makes sense for this box?
There is no strict minimum, but tooling and print setup spread over the run, so small batches carry a higher unit cost and the price falls sharply with volume. For export-scale orders the economics work well. Tell us your launch quantity and annual forecast and we will advise on the break points.
Can you design the insert to fit my exact product?
Yes. Structural design is in-house. Send the dimensions and weight of each part, or a sample of the kit, and we return a fitted dieline and a physical sample before you commit to a run.
What is the lead time?
It depends on artwork sign-off, sampling, and quantity. A typical project moves from approved dieline to sample to production over a few weeks. We confirm a firm schedule with your quote once the spec is set.
Can you match an existing pack or brand color?
Yes. We match to an agreed color tolerance on a defined board and sign off on a contract proof. For a panel-wide solid we recommend a Pantone spot so the color holds run to run.
Do you handle international shipping?
Yes. We export under standard Incoterms such as FOB and CIF, and we advise on pallet pattern and container fit so the box itself does not waste cube and raise your landed cost.
