Acrylic Goods JAN Label and Backing Card Packaging OEM
This page explains how to prepare acrylic stands, acrylic keychains, acrylic badges, coasters, and related character goods for Japan-facing retail, ecommerce, and event delivery with backing cards, OPP bags, JAN labels, SKU control, carton labels, and pre-shipment inspection.
The purpose is not to newly register JAN numbers for the buyer. The buyer or brand supplies JAN, EAN, or UPC data, and the factory turns that data into practical packaging rules: which backing card, which bag, which label position, which carton mark, and which SKU checks should be used before mass production.

What This Page Helps You Decide
JAN label and backing card packaging is not only a bagging step after acrylic goods are finished. It is a packaging-control process that defines scannable JAN position, backing card margin, OPP bag fit, SKU-to-JAN mapping, carton labels, and inspection records in one shared specification.
For character acrylic goods, it is important not to cover key artwork, not to mix backing cards between SKUs, and not to mismatch JAN labels and product names. Confirming both the visual presentation and the control rules at sample stage reduces relabeling, re-sorting, and delivery delay during bulk shipment.
How Different Projects Use This Packaging Setup
Retail and ecommerce delivery
Barcode readability, carton information, carton quantity, and warehouse rules are the priority. Decide whether the JAN label should be outside the OPP bag or on the backing card according to the destination requirements.
Event merchandise
When many SKUs are packed under a tight schedule, SKU sheets and work instructions matter. Label position should be fixed, and the card and bag should support fast sales and clear display.
Series and random items
Character variations, colorways, random packing, and box sets require JAN mapping, assortment ratio, carton numbers, and SKU quantities before mass production starts.

Decide JAN Label Position by Both Design and Scan Readability
A JAN label should not simply be placed wherever there is empty space. OPP bag wrinkles, seal steps, acrylic reflection, backing card graphics, and scan direction at a store or warehouse can all affect readability.
- If the label is applied outside the OPP bag, avoid folds and adhesive areas.
- If it is applied on the backing card, confirm whether the destination can scan it from outside.
- Avoid covering character faces, logos, product names, and important artwork.
- Manage JAN data, SKU code, product name, and quantity in one control sheet.
Role Split Between Buyer and Factory
| Buyer / brand prepares | JAN, EAN, or UPC numbers, SKU codes, product names, quantity by SKU, destination rules, backing card artwork, caution text, delivery instructions, and carton mark requirements. |
|---|---|
| Factory handles | JAN label output from supplied data, label position confirmation, backing card and OPP bag combination, individual packing, SKU sorting, carton label application, and pre-shipment verification. |
| Both sides confirm | With sample photos or physical samples, confirm barcode readability, backing card margin, item movement in the bag, label angle, carton information, quantity, and mixed-carton rules. |
Select OPP Bag and Backing Card from the Maximum Finished Size
If packaging is decided only by card size, acrylic body, stand base, metal parts, protective film, and OPP seal may interfere with each other. A bag that is too large can let the product shift; a bag that is too small can create bent corners or wrinkles. For hanging retail display, the header and hang-hole position also matter.
- For acrylic stands, check thickness with the stand base included.
- For acrylic keychains, choose the bag from the maximum size including hardware.
- Check that the OPP seal does not overlap the JAN label or product name.
- Retail hanging, ecommerce warehouse, and event sales may require different priorities.

Packaging Specification Checklist
| Product types | Acrylic stands, keychains, badges, coasters, blocks, mini dioramas, and set products. Product shape changes card fixation, bag size, and label position. |
|---|---|
| Backing card | Finished size, bleed, hang hole, product name, SKU, series name, caution text, JAN label area, single/double-sided printing, paper thickness, and color review. |
| OPP bag | Bag width and height, header, hang hole, seal direction, adhesive area, transparency, inner margin, protective-film interference, and final packed appearance. |
| JAN label | Supplied barcode data, label size, application position, scan direction, SKU mapping, label material, and checks for bending, wrinkles, or peeling. |
| Carton label | Product name, SKU, quantity, carton number, lot, destination requirement, mixed-SKU status, carton quantity, and total carton count. |

Manage Multiple SKUs with One JAN, Card, and Quantity Mapping Sheet
Color, character, and expression variations may look similar but use different JAN labels. Changing backing card colors or labels is not enough; the packing team needs a clear SKU mapping sheet for checking.
| Fields to include | SKU code, product name, character name, backing card file name, JAN number, JAN artwork file, individual package quantity, carton quantity, carton number, and notes. |
|---|---|
| How to reduce mix-ups | Separate work areas by SKU, manage backing card stacks and JAN label rolls with the same numbering system, recheck quantity before carton packing, and keep shipment photos. |
For Bulk Shipment, Check Individual Packages and Carton Labels Together
Even if each individual package looks correct, shipment can stop if carton SKU or quantity is wrong. Carton number, quantity, lot, SKU, and mixed-carton status should be checked against the individual labels before shipment.
- Check SKU and quantity carton by carton.
- For mixed-SKU cartons, keep a list of items inside each carton.
- If the destination requires carton barcodes or management numbers, share the rule before quotation.
- Define how spare cards, spare JAN labels, and spare bags should be handled.


Pre-Shipment QC Checks Management Data, Not Only Appearance
For JAN label and backing card packaging, inspection should cover not only acrylic scratches or print shift but also JAN-to-SKU match, label position, card direction, quantity, carton number, carton label, and inspection record.
Check label position, scan result, SKU match, duplicates, and wrong labels.
Check front/back side, color, hole position, product name, caution text, and JAN area.
Check bag size, seal, wrinkles, adhesive, hang hole, and product movement.
Check SKU, quantity, carton number, lot, and destination requirements.
Production Flow
This order helps reduce label-position changes after card printing, bag-size changes after OPP bags are prepared, relabeling after production, and carton-label rework before delivery.
Mass Production Risks and Prevention
Barcode does not scan
Wrinkles, reflection, angled application, or overlapping card graphics can cause this. Test the actual label position during sampling.
JAN label covers artwork
Covering faces, logos, or product names reduces merchandise value. Check design and management requirements together.
SKUs get mixed
Similar colors or expressions can be mixed easily. Use the same numbering system for SKU sheets, card stacks, JAN rolls, and carton labels.
Product moves inside the bag
This can happen when the bag is too large, card fixation is weak, or hardware position is unstable. Confirm maximum dimensions and fixation method first.
Carton quantity is wrong
Check carton quantity, total quantity, SKU quantity, and split-shipment destination carton by carton. Keep carton-level checklists for multi-SKU orders.
Destination rules are missed
Ecommerce warehouses, stores, event sales, and consignment sales can require different labels. Share destination rules before quotation.

Frequently Asked Questions
Can the factory newly register JAN numbers for us?
JAN number registration and ownership are normally handled by the brand or seller. The factory uses supplied JAN, EAN, or UPC data to create labels, confirm label position, check readability, match SKUs, and verify packaging before shipment.
Should the JAN label be applied outside the OPP bag?
If a warehouse or store needs to scan the barcode from outside, applying it on the OPP bag is usually easier. For appearance-first projects, the label may be placed on the backing card back side or another position that does not cover the artwork. Sales-channel rules should be confirmed first.
When should the backing card artwork be finalized?
JAN position, hang hole, product name, SKU, caution text, bleed, and bag size should be tentatively fixed before sample review. Final approval should be done with a physical sample or clear sample photos before mass production.
Can you handle multiple SKUs or random items?
Yes. SKU sheets, JAN mapping, backing card data, assortment ratio, carton quantity, and carton label rules should be fixed before mass production.
Can we request only JAN labels?
We recommend checking JAN labels together with backing cards, OPP bags, individual packaging, carton labels, and inspection scope because label position and readability depend on the packaging specification.
What should we send before quotation?
Please share product images or drawings, finished size, thickness, SKU count, quantity, JAN data, backing card artwork, OPP bag preference, carton label requirements, and delivery rules.
