THE STATE OF THE FOLDING CARTON & CORRUGATED MARKETS FIVE PACKAGING AND DESIGN TRENDS FOR 2020 TODAY’S SPONSOR: POWERED BY: WELCOME Welcome to this special publication for attendees of the 2020 PRINTING United Digital Experience. In June, PRINTING United announced the decision to transition from an in-person event in Atlanta, Ga. to a comprehensive digital platform. The PRINTING United Digital Ex- perience, taking place Oct. 26 – Nov. 12, o ers attendees three weeks of live, guided programming, educational sessions, and panel discussions with the experts; along with access to a complete online exhibitor showcase featuring information about the newest industry technology, case studies, whitepapers, the chance to speak with exhibitor repre- sentatives, and more. Today is Day Eight of this 14-day event. Focused on the package printing market — spe- cifi cally the folding carton and corrugated segments — attendees have a packed sched- ule of content and product demos (see the detailed agenda on page 4). According to the Digital Printing for Folding Carton Converting study by PRINTING United Alliance and Keypoint Intelligence, the folding carton segment represents about $18 billion in annual print value in the U.S. and Canada. The Fibre Box Association reports that the U.S. corrugated packaging market represents about $35.2 billion in annual print value. For both of these markets, however, it is estimated that 99% of the products are printed via analog technologies. There is a signifi cant amount of opportunity for digital printing going forward.

  • WHITE PAPER Gable-Top Cartons Considerations for This Container Choice Are High End Graphics and a Quick Turnaround Realistic for Gable-Top Cartons?
    WHITE PAPER Gable-Top Cartons Considerations For This Container Choice Are High End Graphics and a Quick Turnaround Realistic for Gable-Top Cartons? A Little History. Like many multifaceted printers serving food, pharma and consumer packaged good (CPG) categories, our customers’ requests can vary widely. We try to keep our facility and equipment state-of-the-art so we can accommodate a wide range of specifications. In the last five years, we started noticing a trend. Our customers wanting gable top cartons always seem to have the same request – how can I get high end, creative graphics with quick turnaround? Customers using the larger sizes of gable top cartons (the gallon size for example) and customers using heavier, coated paperboard (more commonly called milk stock) especially found their printing choices to be limited to flexographic printing, less sturdy paperboard and low quality graphics. We heard major challenges such as print registration being so poor that you couldn’t even read an ingredients list. The reasons for choosing gable-top cartons were clear to us - customers want the billboard space to tell their story. Cartons give you room for branding and selling. And gable-top cartons can be significantly more affordable, costing up to 30% less than their plastic tub counterparts. If you use plastic to contain your product, you are limited to options and subjected heavily to the petroleum market. After hearing some of these challenges, Carton Service decided to take a look. We evaluated the market and our capabilities and found that there might be an opportunity to help an underserved market.

  • Paperboard Material in Folding Cartons. Paperboard Material in Folding Cartons
    Paperboard Material in Folding Cartons. Paperboard Material in Folding Cartons. In today’s packaging landscape, the choice of raw materials can be daunting. Substitutions are sometimes made with little or no regard to suitability, nonetheless, the differences in paperboard properties and appropriate application are creating some interesting nuances in today’s recovering economy. The choice of substrate is influenced by a number of key parameters including the requirements of print performance, product protection, design features and requirements, sustainability and overall value. This article explains the main paper substrates used in folding carton packaging, as well as their characteristics and primary uses. There are four main types of substrates used in folding cartons: 1) Unbleached Kraft Paperboard 2) Bleached Kraft Paperboard 3) Recycled Paperboard 4) micro-flute corrugate. SUS (Solid Unbleached Sulfate) / CUK (Coated Solid Unbleached Kraft) Unbleached Kraft Paperboard — often referred to as Solid Unbleached Sulfate (SUS), is the most commonly used substrate for folding carton packaging. It is produced from at least 80% virgin- unbleached wood pulp and is coated with a thin layer of kaolin clay and titanium dioxide to improve color, smoothness and printing receptivity. Unbleached Kraft can also be treated with a moisture barrier for use in liquid and food packaging. The use of unbleached, usually softwood pulp results in good tear resistance and the greatest stiffness and strength in relation to basis weight of the paperboard substrates. Thus, Unbleached Kraft often allows for the use of a lower caliper paperboard relative to other substrates. It also has cost advantages over bleached virgin paperboard. Unbleached Kraft is used in many folding carton applications, especially when strength and durability are paramount.
