Durable Technologies offers contact carton and case coders designed for marking on corrugated boxes, bag coding or web printing. Our roller coders are ideal for date coding, batch coding and product identification on both porous and non-porous substrates. Our carton coding system incorporates our interchangeable Pack-Mark® rubber ribbed type and Porelon® Ink Rolls to offer a reliable coding system that isn't reliant on a liquid ink reservoir and can be oriented in any position. They are available in two basic configurations - indexing (single print then reset) or non-indexing (continuous print.)
