Discharge Spout/Bottom Chute - A tube sewn into the bottom of the bulk bag used for discharging the bag.
Discharge System - A piece of equipment used for discharging products out of containers.
Duffel Discharge Spout - A discharge spout with a drawstring type closure that protects the discharge spout. It will not have a reinforcement square.

Polyethylene - A form of plastic film which is used for liners. Also called “P.E.”.
Polypropylene - A petroleum based plastic used in weaving fabric for bulk bags. Also called “P.P.”.
Protective Bottom - An additional piece of fabric sewn to one side of the bulk bag at the bottom with ties on the opposite side. This flap will cover and protect the bottom. Also referred to as a “Diaper”.
RAT- For safety, a Reinforcement strip of webbing is sewn Around the Top of the sides. Sewn on at the same time the top is set, usually out of 1 ½" webbing. (Reinforcement around top)
Recondition - Cleaning, repairing and inspecting bulk bags for reuse.
Recycling - Chopping up and regrinding bulk bags into pellet form to be reused in secondary applications.
Reinforcement Square/Star Closure - A square piece of fabric which is branded with an ”X” and has webbing sewn in each flap for closing. It is sewn over the discharge spout for protection.

Stevedore Straps - Heavy-duty straps, two per bag, threaded through two sets of lift loops to form basket-type straps for a one-point pickup.
Straps - The lifting mechanism of a bulk bag, usually found in the top corners, 10” long from the top of the bag to the top of the loop is standard. Also called “Loops”.
Strap Bag - A bag with straps sewn on each corner, and used for picking up a filled bag.
