Bag Construction

  • U-panel Bags requires two seams along two opposite sides to create two panels and a U-panel shape. This style of bag has become the industry standard in the United States.
  • Circular Bags constructed from woven fabric on a circular loom. The fabric is woven into a continuous tube of fabric and cut to the precise height required. The tubular body design is ideal as a liner less option for fine materials. It is also an excellent alternative to the original four-panel bag construction.
  • Four Panel Bags considered the original polypropylene design. This construction requires seams along four separate pieces of fabric sewn to create a four-panel bag.
  • Baffle Bags involves pieces of fabric sewn into the corners of the bag to help the bag maintain its cube shape after filling. The baffle design is equipped with holes, which allow product to flow through. The baffles helps prevent the bag from bulging and helps sustain the shape of the bag, keeping it upright without losing its shape.

Bag Application

  • Food Grade Bags are made with resins meeting FDA standards used for food purposes. Food grade bags are manufactured in a clean room facility and can be certified by a food safety standard such as SQF, AIB and/or BRC. A food grade bag which has been manufactured by a facility that has been audited and is certified by a food safety standard such as the American Institute of Baking (AIB), Safe Quality Foods (SQF), or British Retail Consortium (BRC) or others, is considered a certified food grad bag. These bags are made of resin that meets the FDA food grade requirements.
  • UN Rated Bags are put through a series of rigorous tests such as, drop test, topple test, and top lift test. The testing is executed by an independent testing facility. Once the bag is UN certified, each bag will be assigned a specific UN number identifying that specific bag. The UN certification usually lasts for one year, or otherwise specified by the testing house, some will certify longer.
  • Multi-trip Bags most bags are designed with a 5:1 safety factor, meaning the bag is rated to hold 5 times the amount of the bags safe working load. A 5:1 is intended for single use bags. 6:1 bags are designed for multi-uses.
  • Chemical Bags used to transport chemicals.
  • Conductive or static dissipative bags (Anti-static) The difference in the two is the flow of the electrical resistance. Conductive bags allow the electrons to flow easily across the bag and charges go to the ground or another conductive object. Static dissipative bags allow the electrons to move slower and more controlled through the antistatic fabric, reducing the charge.
  • Valve bags or liquid bags allow liquid to be stored or transported easily. Valve bags are equipped with a valve port for releasing the liquids in a controlled manner.
