Today's customer is well-informed and wants to know everything about a product before making a purchase. Make sure to provide additional information, as this can be very beneficial. QR codes are essential for offering customers extra information about a product, company, or service, and they can be placed in very small spaces. Avery Zweckform's square QR code labels in a 35x35 mm format reliably cover dark or patterned backgrounds with opaque material, ensuring optimal scanning of the code. The labels are perfectly sized, flexible, easy to print, and quick to apply. They are chlorine-free bleached and PVC-free. Free templates and software are available to print your labels.
