A cardboard gaylord is cheap per trip but loses strength with humidity and is usually single use. A rigid HDPE bin costs more once and is washed and reused for years, so it wins in closed loops between your plants or with fixed suppliers.
Match the footprint to your pallets and racks first, then the height to product density and the 2,000 lb load rating.
Bonar's Roto Gaylord Bin is a rotomolded plastic gaylord that nests and stacks, takes forks from 4 sides and is made with FDA-approved resin. It is the reusable answer when cardboard gaylords keep collapsing.
Liners: for powders or sticky products, add a bin liner so the gaylord stays clean between loads.
Used vs new: used cardboard gaylords are cheap but vary in strength and cleanliness, which is a risk in food plants. A new plastic gaylord gives you known dimensions and a cleanable surface.
