Understanding Terminology

When choosing your nozzles, it’s important to understand the different terminology used in the industry to make sure you’re choosing the right nozzles for your application. Consider terms such as:

  • Carton sealing: This popular use for a hot melt glue gun nozzle consists of gluing carton lids and tops, usually with a single line of glue (sufficient for low-weight cartons and products such as cereal boxes). Many customers choose pencil nozzles or 90-degree nozzles for carton sealing.
  • Case closing: Cases are made from thicker cardboard and often require more glue (thicker lines or multiple lines) for adequate sealing before shipping — heavier products will require more glue than lighter ones for adequate sealing. Optimal hot glue nozzles for case sealing include needle SS nozzles, right-angle 90° nozzles, and multi-orifice domed nozzles are popular choices.
  • Adhesive optimization: Too little glue can result in cartons and cases that open during transport, but too much glue costs you money. Optimizing your adhesive is important for the quality and reliability of your packaging as well as your profitability.
