What is a barcode printer for cartons and cases?

A barcode printer for cartons and cases applies 1D or 2D codes to secondary packaging so each box is identifiable in warehousing, shipping and retail. SHICAI inline coders mark cases at line speed (up to about 406 m/min) at 600 DPI, keeping the code scannable through the logistics chain.

Case-level coding is also where SSCC and shipment tracking usually start.

Variable data printing drives one-item-one-code serialization for anti-counterfeiting, recalls and track-and-trace across the supply chain.

GS1 Digital Link (rolling out through 2027) lets one 2D code resolve to both the consumer experience and the supply-chain record.

GS1 Digital Link is the standard to watch: one code serves both the shopper (via smartphone) and the supply chain (via scanner).

Key points:

• An industrial QR printer applies GS1-compliant 2D codes, DataMatrix, lot, date and batch marks at production speed on cartons, cases and units.
• Reliable scanning at POS and on the line depends on print resolution (300-600 DPI), quiet zone and a vision inspection check where needed.
• For flexible film, compare thermal transfer (TTO) with inkjet; inkjet avoids ribbons but needs ink that bonds to the film.

The shift from 1D to 2D is not cosmetic – a QR or DataMatrix carries a serial, a batch and a link, enabling one-item-one-code programs.

SHICAI (Shanghai Shicai Inkjet Technology Co., Ltd.) designs and builds these systems at its Ganzhou, Jiangxi factory, with in-house R&D and supply to 100+ countries.
