Typically, the pockets on WIP bags are filled by a third-party company instead of by the OEM parts manufacturer. Employees at a kitting or sequencing facility receive parts from multiple suppliers, unload one or more trucks, and then load the parts bags. Sewn fabric dunnage that\u2019s filled with parts is then sent to the assembly facility.<\/p>\n<p>For the assembler, WIP bag pockets that sag aren\u2019t just an inconvenience. Unlike the open pockets on clothing, the pockets on reusable packaging bags contain shelf-like structures made of plastic. If the shelves are too thin or too weak, damage to parts can occur. Damaged work-in-process bags can also incurs costs \u2013 and not just in terms of dunnage repairs. To account for parts bags that are out-of-service, WIP bag owners need to maintain fleets of returnable packaging products that are held in reserve.<\/p>\n<h2>WIP Bags and Dunnage Designs<\/h2>\n<p>When the pockets on a WIP bag sag, design flaws involving material selection are usually to blame. Pcorr, a common type of corrugated plastic sheeting with a fluted, I-beam like structure, is strong in just one direction. If a WIP bag part doesn\u2019t lay perfectly flat, point loading can occur. Depending on the part\u2019s shape, stress is concentrated in a single point or spot. This can cause the plastic to break, especially if a packaging designer has specified a 4 or 5 mil sheet that\u2019s too thin for the application.<\/p>\n<p><a href=\"https:\/\/hold-true.com\/2017\/04\/rack-bag-design\/\">When dunnage is designed digitally<\/a>, a packaging engineer may only account for the overall weight of the part. If the designer doesn\u2019t consider part loading, stress calculations are incomplete. That\u2019s why at Hold-True, we don\u2019t just look at your CAD files. We load your sample parts into prototype bags to see if there\u2019s pocket sag. We also account for the way that assembly personnel use work-in-process bags. If your design doesn\u2019t account for how people grab and collapse WIP bags, we\u2019ll address dunnage use (and misuse).<\/p>\n<h2>Choose Work-in-Process Bags from Hold-True<\/h2>\n<p>To strengthen your WIP bag designs, Hold-True may recommend <a href=\"http:\/\/www.conpearl.com\/\">CON-Pearl\u00ae<\/a>, a strong but lightweight plastic material, for the shelves. Unlike Pcorr, CON-Pearl provides strength in every direction. The key to this advanced plastic is the middle layer, where \u201cpearls\u201d formed in polypropylene film support multi-dimensional stability. CON-Pearl isn\u2019t required for every application, and some support structures may surprise you. With rack bags, steel tubes that support the shelves can be lighter than plastic.<\/p>\n<p>Do you need work-in-process bags, or do you have questions about the best way to design WIP bags for your specific application? Skimping on shelving materials can reduce upfront costs, but you may face higher maintenance expenses and need larger fleet sizes. Failed shelves can mean higher inbound scrap rates, too. Sewn fabric dunnage that\u2019s <a href=\"https:\/\/hold-true.com\/2017\/04\/fabric-dunnage-costs\/\">hard-to-clean<\/a> also costs you time and money.
