Estimating Hot Melt Coverage

There are many factors that are important when buying hot melt besides what’s in the formulas. Astro Packaging understands how hard it can be to determine the cost and coverage of hot melt. We want to guide you and make your life just a little easier by showing you some simple equations for finding your hot melt coverage and cost.

Dot Reference

You can estimate total dot size by dispensing in dots. For exact dot dispensing, see the cutting-edge Astro Packaging hot melt units line. These machines help produce the same drop every time for complete accuracy.

  • 1/4” dot size will give your approximately 9,500 dots per pound or approximately .10 pounds per 1,000 dots.
  • 1/2” dot size will give you approximately 2,300 dots per pound or approximately .42 pounds per 1,000 dots.

Linear Reference

Each line size is not created equal. You need to know your correct line size to accurately estimate how much hot melt is needed for your application. Bead size will also vary due to different size nozzles.

  • 1/16 “ linear bead will give you approximately 1,600 feet per pound or approximately .6 pounds per 1,000 linear feet.
  • 1/8” dot size will give you approximately 425 dots per pound or approximately 2.3 pounds per 1,000 linear feet.
  • 1/4” dot size will give you approximately 180 dots per pound or approximately 5.4 pounds per 1,000 linear feet.

Overview

Dots: (Dots per piece x pieces per hour) = dots per hour / dots per pound = glue pounds per hour Linear: (Feet per applications x applications per hour) = total feet per hour / feet per lb. = glue pounds per hour needed.
