Walmart roils the case-coding waters

Online ink-jet printing of GTIN on cases is a key to late-stage customization that lets CPG companies minimize the cost of corrugated. Now Walmart is banning ink-jet GTIN.

A recent policy announced by Walmart has Consumer Packaged Goods companies across the country scrambling for solutions that will bring them into compliance. Not only does the new policy rule out ink-jet printing on cases for the 14-digit Global Trade Item Number (GTIN) and the barcode symbol representing that number, but it also stipulates that all four sides of a corrugated case must carry trade item information. The announcement does not include Sam’s Club stores. And in Walmart stores it pertains only to food items, including frozen foods but excluding fresh meat, fish, poultry, and produce.

Aside from e-mail correspondence between Walmart and its CPG suppliers, the only real documentation that has been issued is a PowerPoint presentation dated February 16 2016 that’s titled “Walmart’s Case Labeling Standards and Expectations.” It was this PowerPoint that was used by Sarah Alderson, Walmart Senior Buyer Frozen Foods, in a March 16 online presentation and Q&A. Among the requirements spelled out in the PowerPoint are some that haven’t ruffled too many feathers, including these:

• Walmart Department Number must be printed.

• Case Pack quantity must be printed as well as a space where Walmart store associates can manually note any change in case contents. For example, the associate would write the number 4 in this space if he or she has removed two items from a case that originally held 6.

• Temperature rhetoric like “Keep Frozen” must be included.

• If a case is retail-ready (i.e., it’s perforated or otherwise designed so that a store associate won’t need a tool to open it and place it on a store shelf), “PDQ” must be printed on the top flap to indicate this.

But alongside these relatively innocuous requirements are two others that are causing real consternation (for simplicity’s sake let’s call them Requirement A and Requirement B):

Requirement A. 14-digit Global Trade Identification Number (GTIN) must be printed flexo. Ink jet is not in compliance.

Requirement B. All four sides of the case require item information.

We’ll get to Requirement B shortly. As for Requirement A, it’s driven by Walmart’s claim that GTIN barcodes that are ink-jet printed are too often so illegible that they can’t be scanned by store associates wielding hand-held scanners. When a barcode is unscannable, electronic data transmission both within Walmart and with its outside trading partners is compromised. That means Walmart’s inventory and stock replenishment records must be updated in some way that is not automatic. The time spent on this essentially manual activity is time wasted, says Walmart. Flexo printing would eliminate this waste of time.

Why the fuss?
So why does a ban on ink-jet printing of GTIN codes on cases have CPG companies up in arms? Because ink-jet printing is a key element of the late-stage customization strategy that CPG companies rely on to keep corrugated inventories to a minimum. Suppose, for example, that ABC Yogurt Company makes the same 6-oz yogurt product in grape, cherry, pineapple, peach, and strawberry varieties. The identical case can be used for all five varieties. The firm’s corrugated supplier uses a flexo press to print the ABC Yogurt logo on all of the cases. Because the artwork is the same for all the cases, it means large orders, long runs, and fewer printing plate costs. All of this maximizes efficiency and reduces overall cost. And the flavor variations? They get ink-jet printed on ABC Yogurt’s packaging lines along with the GTIN that is specific to each flavor variety, as well as lot and date code info. It’s late-stage customization at its best.

With ink-jet printing of GTIN no longer in compliance and only flexo-printed GTIN allowed, it means that ABC Yogurt will no longer be able to use ink-jet printing to customize its cases with flavor varieties. Instead, it will have to have its corrugated supplier flexo-print five different cases—one each for grape, cherry, pineapple, peach, and strawberry varieties—where it now prints just one. That will shorten case-printing runs, add to the number of printing plates required, increase inventory complexity fivefold, and drive up costs. It will also greatly increase the likelihood of packaging obsolescence, which will result in more corrugated cases going to the landfill—so much for sustainable packaging.

Also adding to the potential for waste, say some observers, is that some CPG companies simply won’t have room inside their facilities to store all the extra cases they will have to keep. So they’ll store some of their corrugated outside. But corrugated cases are not meant to withstand the temperature and humidity fluctuations that come with outside storage. This could lead to damaged inventory having to be thrown out. Or, just as bad from an efficiency standpoint, compromised cases will reach the automated case erecting and case packing equipment in the plant, resulting in downtime due to jams.

To gauge the potential impact of Requirement A and Requirement B, Packaging World conducted a survey of CPG companies. Naturally, we asked how much the flexo-only requirement would cost. As shown in Figure 1, 40% of respondents indicated that this requirement would bring them a cost increase of up to 10%, 24% said up to 20%, and 13% said costs would rise by more than 30%.

Verbatim comments were also solicited in the survey, and one respondent, a maker of salsa in four flavors, wrote as follows: “I am a small company trying to grow with Walmart. I order all my [packaging] supplies in large numbers to keep the cost down. This does not help!” Another respondent said it would mean having to inventory preprinted cases for 150 different model numbers. A third said “Maybe Wally World should train their employees,” and a fourth said, “Walmart needs better scanners.”

Worth noting where this last comment on scanners is concerned is that Walmart announced last June that by October 2015, it would replace outdated Telxon hand-held scanning/ordering devices with new Zebra MC 40 units having greater functionality. Sources indicate that the replacement process is still underway.

One more verbatim comment should be included here, if for no other reason then simply for how thoughtfully and thoroughly it catalogs the difficulties Walmart is foisting upon its suppliers: “We will have to change from generic cases that can be used for hundreds of SKUs to individually printed cases. This means more print plates will be required (which have to be purchased, stored, and maintained), shorter runs at our corrugated supplier, more change overs between short runs at their location, increased inventory of otherwise identical cases, and more warehouse space to store all the SKU-specific cases. This will be true before it ever leaves the supplier’s location. By changing to individually printed cases, we will need to buy many more print plates, which will increase our budgets; we will need to store more SKU-specific cases in-house, which will increase our on-site inventory as well as space requirements to store the material; we will have more case packer change overs, which will be required for each SKU, which will create more downtime; there will also be added QA resources required for incoming inspection due to the increase in the number of print variations in our plants. I’m sure there are more unintended consequences that we have not yet identified.”

Walmart’s beef is legit
Regardless of how much the ban on ink-jet printed GTIN will increase costs for CPG companies, and regardless of the displeasure that echoes in the verbatim comments we received in our survey, many knowledgeable observers are quick to agree that some of the criticism leveled by Walmart is perfectly justified. Yes, they agree, there are a lot of bad ink-jet printed barcodes on corrugated out there. Among those in agreement is Rick Fox, the president of Fox IV Technologies, a supplier of print-and-apply labeling solutions.

“Can ink jet systems print in-spec barcodes in a manufacturing environment?” asks Fox. “Certainly, and ink-jet equipment OEMs can provide great samples. But it means nothing if Walmart associates are having a problem, and I know for a fact from research I’ve done in the field that they absolutely do have a legitimate problem. Why do you think Woolworth’s of Australia, which is essentially the Walmart of Australia, hasn’t permitted ink-jet case coding of GTIN for nearly 15 years now? I would argue that where the Walmart issue is concerned, the breakdown is not in the ink-jet equipment, it’s in the CPG company’s use of it.”

Our survey respondents seem to agree with Fox’s argument. A look at Figure 2 shows that nearly half of respondents believe that the CPG company’s failure to properly maintain ink-jet print heads is most often the reason why Walmart has problems with ink-jet-printed barcodes. This verbatim comment by one survey respondent sums it up nicely: “More often than not it is an operational issue that is easily correctable (i.e. align conveyor rails). Proper operator Q.C. checks can reduce the possibility of poorly printed cases leaving the plant to almost zero. If nothing else this should be a wake up call to manufacturing managers everywhere to take case code dating seriously.”
