Labels that meet the GS1 spec
Direct thermal labels in the GS1 logistics formats used on pallets and production lines.
GS1 specifies A6, 105 x 148 mm, when only the SSCC or limited data is carried, and A5, 148 x 210 mm, when trade item data is added. GS1 does not recommend anything smaller than A6 for a logistics label. Both sizes are stocked here on a 76 mm core for industrial printers.
The square 100 x 100 mm and 102 x 102 mm formats suit carton and pallet identification where a full logistics label is not needed. Sold by the carton.
