Bulk Bags Wholesale

Type A

Type A bulk bags are basic, all-purpose bags. No special requirements or designations for this type. No hazardous material or electrostatic capabilities. Non-flammable products only, not to be used in areas with explosive potential or around flammable gases.

Type B

Type B bulk bags have a fabric with a low breakdown voltage insulating fabric. Used in the presence of combustible dusts with MIE of greater than 3mj but not around flammable vapors. Use these bags to safely transport flammable powders.

Type C

Type C bulk bags have the capability to be electrically grounded. These bulk bags have conductive threads woven throughout the bag and are connected to tabs which must be grounded during filling and/or discharge. The threads dissipate static energy safely from the surface of the bag. Use these bags to safely transport flammable powders or when flammable dust or vapors are present.

Type D

Type D bags are static dissipating bags similar in use to Type C, but do not require grounding the bag. Instead the fabric itself has special additives which give it static dissipative qualities. Use these bags to safely transport flammable powders or when flammable dust or gases are present.

Baffles are pieces of fabric inside of the bag that are sewn to each corner. The baffles help the bag maintain a cubed shape when filled, preventing the bag from bulging. Baffled bags maintain a rigid shape and are more efficient in their use of space.

A duffel top bulk bag is essentially a bag with a lid. It has a lightweight panel on top. It can be opened and tied closed. An open top bulk bag is a bag without a closure, keeping the product exposed.

Bulk bags are made from 100% virgin polypropylene.

Woven polypropylene is made from extruded polypropylene resin, which is made from petroleum feedstocks.

Bulk density is the property of the product that you are filling into the bulk bag. It is the mass of the product divided by the volume it occupies. The volume includes the space between particles as well as the space inside the pores of individual particles.

A standard fill spout is a spout with a 14” diameter opening in the top (center) of the bag, usually 18” long. It is designed to allow the user to fill the bag, minimizing dust occurrences as the bag is being filled. The length of a standard fill spout is 18” long. Spouts can be customized to fit an individual application.

A perimeter band is a band sewn around the outside perimeter of the top of a bag, which is designed to give extra strength to loops when lifting.

A B-lock is a spout accessory designed to assist in the closure to the spout. It is a quick and easy way to close a spout, manually regulating the flow of product. The device locks quickly and easily, and replaces the normal tie usually sewn to a spout.

A diaper bottom bulk bag is a full open bottom bulk bag that has a flap that covers over the open bottom. Once the flap is untied, the bulk bag can be discharged quickly through the open bottom.

Woven polypropylene is breathable. Air and water will flow through an uncoated bulk bag. For applications that require a great deal of breathability, some users use a ventilated bulk bag.

UN Certification is a testing certification done by an independent testing facility, that put the specified bulk bag through a set of rigorous tests, i.e. drop test, topple test, and tear test. A UN test can include a vibration test which will certify the bag for DOT as well.

Usually 1 year from testing.

Food grade bulk bags are bags that are made with the intent of using the bulk bags in a food grade facility for the packaging of food products.

Yes, our manufacturer has a HACCP plan in place for manufacturing bulk bags.

Bulk bags are traceable by lot numbers given at the time of manufacturing. Each bag has a specific lot number associated with its manufacturing date and lot.
