Full Flap Bottom 5-Wall Gaylord Boxes

FOL stands for "full overlap" — another industry term for the same construction. Full flap bottom, full bottom flap, and FOL all describe a bottom where the inner and outer flaps overlap completely, giving a double-thickness base.

Yes, practically speaking. The 3,000 lb static load rating is the spec for 5-wall construction with a full flap bottom under column-load conditions. Partial flap bottom is rated for lighter practical loads (~2,000 lb) because the single-layer base flexes under high weight.

Often yes — depends on filled box weight and rack ratings. The column rule (stack × filled weight ≤ 3,000 lb) governs. At 1,000 lb fill weight, 3-high is straightforward. At 2,000 lb fill, stick to 2-high or single-stack.

Typically 5-15% more per box at equivalent quantity, because it uses more board and takes longer to fold. The cost difference is small relative to the difference in practical load capacity and stacking strength.

Yes — industry data and our own inspection records put bottom failure at roughly 65-70% of reported Gaylord box failures under heavy or dynamic loads. Wall failure and corner crush make up most of the remainder.

Food-grade is about fiber and liner, not bottom construction. For bulk food ingredients at or near the weight cap, full flap bottom is recommended regardless. For lighter dry product, partial flap is usually enough.

Stock sizes ship in 2-5 business days. Custom prints or non-standard board grades add 2-3 weeks.

Yes — used inventory commonly includes full flap bottom construction. Specify in your quote so we filter inventory to that build style.

Shipped flat-bundled to maximize freight efficiency, then assembled at your dock with tape, staples, or glue. Full flap bottom takes a few seconds longer to fold than partial flap because of the additional overlap.

Different things. Full flap bottom (FOL) is a flap-folding pattern that doubles the base. Double-wall bottom is a construction with two complete sheets of board glued at the bottom — much more expensive and used for extremely heavy or fragile loads. Standard 5-wall full flap bottom covers nearly all industrial use cases.
