acceptable moisture content in corrugated boxes

• 8 September 2023

Most plants are now checking their combined board's total moisture content, measuring it off of the dry end of the corrugator with an automatic weighing and drying oven (see Special Note). 2 0 obj Functionally, corrugated becomes brittle and crinkly. It is useful and instructive for box design considerations to quantify the expected strength loss as a function of the equilibrated moisture content of corrugated board and so minimize box failure in high humidity . And unfortunately, humidity is one factor that cannot always be controlled. Excessive moisture or water can soften or dissolve the corrugating adhesive, causing delamination; a box that literally falls apart wont offer much protection. Stay up to date with all the latest Joint Commission news, blog posts, webinars, and communications. The total amount of paper and paperboard combusted in 2018was 4.2million tons. 2023 PMMI Media Group. The most common culprit of compression-loss is boxes hanging over the edge of the pallet. The solution here is to make sure you are using the proper pallet size or the proper palletizing pattern to avoid overhang. Water is used in the corrugated board production and aids in creating the liner board, forming the flute structure, and as part of the starch adhesive that combines them. Heat and humidity are the two biggest enemies of packaging strength. Paperboards were subjected to WVTR test for 7 days at 22C temperature, 55% humidity and 42C temperature, 85%humidity values using Thwing-Al-bert EZ-Cup Vapometer Permeability Cups.

The porosity of wood fibers, which is what corrugated boxes are made of, allows it to absorb and release moisture, a phenomenon that isknown as hygroscopy. Through leading practices, unmatched knowledge and expertise, we help organizations across the continuum of care lead the way to zero harm. The tear-resistant qualities of corrugated cardboard are hard to beat and they have the added advantage of guarding against moisture, so food items are kept fresh. 4 0 obj EPA also estimated the recycling of plastic products based on data published annually by the American Chemistry Council, as well as additional industry data. It combines loading pallets straight and turned. Heat can reduce the moisture content of corrugated boxes, making them brittle. Virtually eliminates load crushing by distributing the force of the film over the entire load, without the use of corner boards, Can take a shock or vibration and still maintain the load in its original unitized configuration, Material cost per pallet is less than shrink wrapping or strapping, Equipment is less expensive than shrink wrapping, bagging or automatic strapping equipment, Provides lower operating and maintenance costs, Provides a large energy saving over shrink wrapping, May be produced tinted or opaque for product identification or pilferage prevention, Provides less resistance to moisture than shrink wrap, Cannot be used to (vertically) compress a pallet load because its primary holding force is in the horizontal direction. . After the manufacturing process, the corrugated board is cut into sheets and stored in a stack until optimum moisture content has been reached in order to Incidentally, superimposed weight should be like-on-like, meaning, weights other than corrugated should not be superimposed on unit loads of corrugated. 2)XxN=.26^k )B7/-:vb aZ-NQ@4M EPA estimated the generation of aluminum packaging at 1.9 million tons in 2018, or 0.7 percent of MSW generation. }]'YfN U zQnh)=nozo3gip&I|-5S|G~x?SAYY?\YX5~Z0oE8f6:34cw& XvZ-r) 4xB*vtlZsvq{ s8eSp|GcS*=hX f+*Pga!,#`~PT(9Ux]Ep|%P?>/+|xI 2$J[sASSt!X%PE$tC]a =J@5.F2` q p-"Aw;q^0rDNQNdS0Z"'Szt#c7Fz{DTm+p?iKB0)i:,3bJA41) In 2018, approximately 32.1 million tons of corrugated boxes were recycled out of 33.9 million tons of total paper and paperboard recycling. Our team has worked with countless companies whose boxes have faced just about every environmental condition imaginable. Glass containers include beer and soft drink bottles, wine and liquor bottles, as well as bottles and jars for food and juices, cosmetics, and other products.

Ensure that pallets are free of nails, large splinters, and other sharp objects that can damage corrugated boxes. Berry et al., 2019; Peleg, 1993), and thus the value of EMC (equilibrium moisture content, kg/m 3 ) is estimated by using the PFP model as shown in Equation (15 Review only, FAQ is current: Periodic review completed, no changes to content. Boxes and containers may have been exposed to unknown and potentially high microbial contamination. What is the national standard for moisture content of carton board Data on the production of wood packaging are derived from purchased market research and research from the Center for Forest Products at Virginia Tech and the United States Department of Agriculture's Forest Service Southern Research Station. Extreme cold also affects moisture content, making the boxes more fragile. This can be done by using a stretch wrap machine, or by simply spiral wrapping the load by hand. For this analysis, EPA classified products made of paper and paperboard materials as either nondurable goods or as containers and packaging. Aesthetically, corrugated takes on a faded, dried-out appearance, even through kraft-brown liners. Copyright 2023. Consider: Is there overhang or underhang? Phone: 317-872-0097 Number 8860726. Experience has demonstrated that a target moisture from 5.8 to 7.5% total combined board moisture works well throughout the year. MoistTech is very experienced with the requirements in the corrugated board moisture control process. He can be reached at[emailprotected]. You need to be laser focused on specific targets, so you know exactly where to make improvements. Each component of the supply chainpackage design, manufacturing, transportation, warehousing/distribution, retail support, retail operationsas well as Mother Nature herself can be a source of damage. Corrugated boxes also represent the largest single product of recycled paper and paperboard containers and packaging. <> | Corrugated box design - Wikipedia EPA estimates the recycling of steel packaging in 2018 as 1.6 million tons, or 73.8 percent of generation. We remember those who have lost their liv From their unique branding depicting the legend of the '@BlastedChurch' to their award-winning wines & strong commu On the one hand, the story of Okanagan Falls, BC, winery Blasted Church Vineyards is similar to many others in the region.

In cool and dry areas, consider using lamination as a finish. A matter of protection: The environment or the product? Corrugated cardboard boxes are no exception. Less-than-ideal or fluctuating climate conditions reduce corrugate effectiveness and shorten its useful life. As much as can be said about the benefits of using mechanical means to get corrugated in and out of storage, there are times when corrugated is handled manually, for example, a worker carrying a bundle (perhaps held together by plastic straps). These latter quantities are not well documented, but the Agency estimated that amount of generation was 340,000 tons in 2018, none of which moved on to recycling or composting. If you work in the seafood industry, you know exactly how delicate the process of transporting the latest catch to its point of sale can On April 28, we join the rest of Canada in observing the Day of Mourning. A dash in the table means that data is not available. The moisture content of the box is determined by environmental relative humidity. In addition to any aforementioned approaches that can be modified for low humidity, inventory control can be effective, utilizing FIFO (first-in-first-out). All rights reserved. EPA measures the generation, recycling, composting, combustion with energy recovery and landfilling of paper and paperboard products. Once a box is formed, both before and after it is filled with product, maintaining its moisture content is critical to maintaining the boxs compression strength. Introduction 19-0 . On the other hand, there is the potential for a significant amount of undamaged product being rejected. When building pallet loads of flat boxes, use deck boards to distribute weight evenly. All rights reserved. Our sensor calibrations, measurement wavelengths, algorithms and sensor optical requirements are pre-set at the factory. We know, boxes are not rocket science. Container and packaging products, especially corrugated boxes, are among frequently recycled products. In 2018, the recycling rate of generated packaging and containers was 53.9 percent. Before putting together a plan, lets examine how product damage occurs and some questions to ponder. When it is impossible to avoid extremes or fluctuations, bring the boxes to the packing line or another area for a period of time to condition them to a more normal atmosphere before using them. EPA estimated 14.5 million tons of plastic containers and packaging were generated in 2018, approximately 5.0 percent of MSW generation. How to ensure your best conveying project yet. The data below are from 1960 to 2018, relating to the total number of tons of aluminum containers and packaging generated, recycled, composted, combusted with energy recovery and landfilled. Following these simple guidelines will maximize the performance and prolong the useful life of your corrugated boxes: The preceding information and illustrations on how to store and handle corrugated boxes are from the Fibre Box Handbook (Fibre Box Association, Rolling Meadows, IL, 1992), Do you have a project GLBC can help out with? This too can cause significant compression losses in the unit load. EPA estimated that the generation of these glass containers was 9.8 million tons in 2018, or 3.3percent of MSW generation. The construction of a box can become even more complicated for dangerous goods. Consider that while shifting to more eco-friendly materials meets consumers increasing demand for more-sustainable packaging, the likelihood for damage rises. The new national standard "corrugated board" GB/T6544-2008 stipulates that the moisture content of paperboard should be no more than 14%, that is, an upper limit for the moisture content of cardboard. Remember, without the lowly corrugated box, the product cannot be shipped!
