Rack Bag Design
Written by Steve Melito on April 4, 2017 in Rack Bag Design

Rack bag design isn’t just about pocket size or material selection. Sewn, reusable fabric dunnage needs to meet the needs of the hard-working people who load and remove parts from these material handling systems. Today, packaging engineers can design fabric rack bags using digital 3D drawings. CAD programs let an engineer design reusable packaging around a part, too. Yet software won’t consider the needs of the workers who use your work-in-process (WIP) bags. If labor is inefficient, your bottom line suffers.

Digital Rack Bag Design

With rack bags, CAD programs can help you to determine which parts lay down and which parts stand up. CAD software is great for determining pocket sizes, too. Still, there are limitations to what digital technology can deliver. For example, a digital drawing won’t tell you if a part will tip one way or the other. You can’t tell how hard it will be load or unload a WIP bag, and you won’t know if parts will cause the bag to tear. That’s why Hold-True, an innovative supplier of rack bags, doesn’t just look at your design files.

Hold-True asks questions, analyzes your answers, and applies what we’ve learned since creating our first sewn fabric products in 1980. With our hands-on approach, we’ll sketch WIP bag designs on a white board and then cut and sew prototype bags that fit the racks you’ll use them with. At Hold-True, that’s what we call “analog design”. Compare our rigorous approach to sending your schematics to a design house that’s never loaded a fabric rack bag or used a sewing machine. How can a company like that meet your needs?

Analog Rack Bag Design

Hold-True’s analog approach is both creative and iterative. We examine every aspect of rack bag design and make adjustments as necessary. If you ship us a sample part like the grill of a heavy truck, we’ll load it into your prototype bag to make sure the part’s weight doesn’t cause the fabric bag to lean. We’ll also look for ways to reduce material usage and speed production. If there’s a way to use a single piece of fabric instead of cutting the sides and roof, we’ll find it. Hold-True considers all the design tradeoffs, too.

For example, reducing the height of a fabric rack bag may keep it from leaning, but a bag that’s too short won’t help your assemblers. Plastic shelves can provide stiffness, but a better polymer can add stability. Hold-True can also reduce rack bag weight and replace buckles with lightweight supports. By designing a rack bag that used steel pipes instead of sequential buckles, we reduced weight and cost while increasing labor efficiency. This fabric dunnage design reduced part damage, too.
