Pakcaging Styles
  • Pillow Bag: This is the most widely used pouch style for hardware furniture fittings when using a vertical packaging machine. It is formed with two horizontal seals (top and bottom) and a longitudinal back seal, creating a pillow-like shape. Pillow bags are ideal for packing hardware items like screws, bolts, and nails. The simplicity and cost-effectiveness of this pouch make it highly suitable for bulk packaging and retail settings.
  • Three-Side Sealed Pouch: A vertical packaging machine can also produce three-side sealed pouches, which are sealed on three sides, leaving one side open for filling before sealing. This type of pouch is well-suited for assortments of hardware pieces such as hinges, brackets, or mixed screws, providing secure and straightforward packaging. It also makes organizing and storing small parts easier for consumers.
