I-10 Gulf Coast: bulk bag freight lane

What moves on the I-10 lane

What fills bags along the Gulf

From the Houston Ship Channel to the Mississippi River below Baton Rouge, the coast is lined with refineries and chemical plants, and many of them pack their dry product in FIBCs. Polyethylene and polypropylene pellets, catalysts, salts, pigments and additives leave these sites by the bag. Dow's Freeport, Texas complex and Formosa's Point Comfort, Texas plants, both named in a 2018 report, sit near the water south of the interstate.

Farther east the mix changes. Southwest Louisiana and the upper Texas coast grow rice. The Florida Panhandle is timber and paper country. Around Mobile there are chemical plants and a working port. Each asks something different of the bag: food contact for rice, static control for flammable powders, a liner for anything that takes on moisture in Gulf humidity.

For dry flammable powders the static type matters more than the price. Type B fabric prevents propagating brush discharges but cannot be grounded, and it is only for places with no flammable vapour or gas. Type C has conductive threads and must be connected to ground while it fills and empties; with the ground clip off it is unsafe. Type D dissipates charge without a ground connection. Check IEC 61340-4-4 and the bag maker's documents, and follow your site's hazardous-area assessment before you choose.

Ports, river crossings and the interchanges that matter

Port Houston owns and operates eight public facilities along the 52-mile Houston Ship Channel, including the Bayport and Barbours Cut container terminals, so an export load of bags in Houston usually ends at a container yard rather than on the interstate. New Orleans works cargo on the Mississippi, Lake Charles has its own port on the Calcasieu Ship Channel, and Mobile and Jacksonville both handle containers.

The road crosses a lot of water. It enters Louisiana over the Sabine River, runs on a long elevated bridge across the Atchafalaya Basin between Lafayette and Baton Rouge, and crosses the Mississippi at Baton Rouge. East of New Orleans a twin span carries it over the eastern end of Lake Pontchartrain toward Slidell. At Mobile it dips under the Mobile River in a tunnel where hazardous cargo is restricted, so a placarded load routes around it, then crosses Mobile Bay on a causeway.

Pallets of bales or a full trailer

A bale is a stack of folded bags strapped into a bundle, and bales ride on pallets. One or two pallets of new bags to a packager in Lafayette go LTL: the freight moves through terminals, may be handled more than once, and needs a dock or a liftgate at the delivery end. A full 53-foot trailer to a resin plant in Baytown goes truckload, straight from shipper to dock, and works out cheaper per bag if you have room to store it.

Filled bags are a different job. On dense product a trailer reaches its legal weight before it runs out of floor, so we ask the bulk density first and work out how many filled bags fit from there. Empties are the opposite: light and bulky, best baled tight so one pickup clears as many as it can.

On the Gulf, LTL suits a trial order or a top-up to a plant between truckloads. Truckload suits a packing line that empties a trailer of bales on a steady cycle.

What to send us for a Gulf Coast delivery or pickup

Put it in one message and we quote the bag and the freight together. We don't promise a delivery window or a price until a carrier has accepted the load; we tell you which lane it rides, what the trailer holds and what is still open.

• The spec off the label or your drawing: SWL, safety factor, size, top, bottom, loops, fabric, liner, static type.
• The product, and whether it is food, pharma, a flammable dust or none of these.
• Delivery ZIP, plant gate or warehouse, dock or liftgate, and the site's driver safety rules.
• How many bags, and whether they come on one truckload or several LTL drops.
• For a pickup: how many empties, how they are baled, what they held, and whether they are 5:1 or 6:1.
• The day the fill line needs them, so we plan backward from it.
