Aluminium foil lid coding is a common application for the dairy industry who apply code directly to yoghurt, cream and custard pots.
The use-by-dates, batch numbers or variable information applied must be high-resolution and durable to guarantee consumer safety and product traceability.
On-line coding of aluminium foil lids
Thermal inkjet (TIJ) printers are capable of producing, clear, quality prints onto most non-porous substrates, including aluminium foil lids. The mess-free, maintenance-free units use drop-on-demand technology to avoid spillage and contamination.
Foil lids commonly cover perishable items, therefore coding must be fast and efficient, with minimal downtime. TIJ technology is ideal for dairy production lines, as the printers start up and shut down instantaneously.
Multiple printers can be wirelessly connected, allowing one operator to control the formats away from the production line. In turn, printers can be closely monitored, reducing the risk of product recalls through misprinting.
