A transport and storage container costs three times a crate. How is it cheaper?

Answer: The comparison is per cycle: the crate spreads 160 over one trip, the case spreads 780 over 140.

Why not replace everything with steel bins, which are stiffer?

Answer: Stiffness is not corrosion resistance: a scratch rusts within 240 hours, and welds pool water.

Corrugated boxes are strong enough. Why change?

Answer: Only while dry: after 48 hours of water uptake a carton loses about 40 percent.

How does a plastic tote differ from a transport and storage container?

Answer: Wall, sealing and repairability. The tote is 2.5 mm and brittle at minus 10 Celsius; the case is 6 mm with a replaceable gasket.

Which figure is most often wrong?

Answer: The denominator. Theoretical cycles flatter the reusable option, so count recovered cycles.

Transport and Storage Container vs Four Alternatives

Quick answer: A transport and storage container differs from crates, cartons, steel bins and moulded totes in four places: how life is counted, how repair works, the structural ceiling on stacking and sealing, and the denominator under cost per cycle. High-frequency closed loops favour the rotomolded case; one-way lanes favour the carton.

FAQ

1. Transport and Storage Container against Four Alternatives

Five box types share one sheet, where unit price tells you almost nothing. A crate is nailed from 12 mm panels and suits one trip; a carton is lightest, strength in the flutes; a steel bin is stiff but needs repainting; a moulded tote turns brittle in cold. A transport and storage container is rotomolded at 6 mm, between steel and carton in weight.

Type	Forming	Weight	Fit
Plywood crate	Nailed 12 mm panels	18 kg	One-way export
Corrugated box	Five-ply board	Under 2 kg	One-way, light
Steel bin	Welded 1.2 mm sheet	22 kg	Heavy in-plant loop
Plastic tote	PP moulded, 2.5 mm	4 kg	Short light loop
Transport and storage container	Rotomolded PE, 6 mm	9 kg	Medium to long loop

The steel bin weighs more than twice as much, and that mass is lifted every time.

2. Service Life and Repairability

Life cannot be compared in calendar years. A crate lasts a few handlings; a carton loses about 40 percent of its compression strength after 48 hours of water uptake; a steel bin rusts within 240 hours of a scratch and needs drying time after repainting; a tote has no serviceable parts. On a transport and storage container the wear parts are gasket and latches, and a swap takes 8 minutes.

Type	Design life	Replaceable	Downtime
Plywood crate	1 to 3 trips	None	Whole unit
Corrugated box	1 trip	None	Whole unit
Steel bin	Over 5 years	Hinges, latches	Paint drying
Plastic tote	2 to 3 years	None	Scrapped
Transport and storage container	Over 8 years	Gasket, latches	One part swap

Repairability decides how life is counted: parts per year, or the first crack.

3. Stacking and Sealing Limits

Stacking depends on wall stiffness and bearing area; sealing depends on how the lid closes. Both are structural; foam changes neither. A carton bows at three tiers; a tote stacks five high empty and half that loaded; a steel bin holds six static. A transport and storage container has ribs under the floor and holds four tiers at 600 kg.

Type	Tiers	Sealing	Water risk
Plywood crate	4	Inner poly bag	Medium, bag tears
Corrugated box	3	None	High, strength drops
Steel bin	6	Welds plus strip	Medium, welds pool
Plastic tote	5 empty	Flat overlap	Medium, no gasket
Transport and storage container	4	EPDM, 25 percent	Low, hoseable

A flat overlap keeps dust out and water in; a gasket works by compression, and below 20 percent it fails.

4. Cost per Cycle without Distortion

Divide price by trips. A crate at 160 costs 160 per trip, a carton at 40 costs 40, and the rotomolded case at 780, with 35 a year in upkeep over 140 cycles, lands near 8.

The denominator breaks first: real counts lose cases to retention, and the numerator leaks gaskets, latches and washing.

5. Choosing by Turnover Intensity

Read together, the four dimensions sort by turnover. Under five trips a year, crates and cartons win: the denominator is too small. Between twenty and sixty trips indoors, totes and steel bins both work. Above sixty trips on a damp lane, the case finally falls below disposable packaging.

Conclusion

The gap comes down to how life is counted, how repair works, the ceiling on stacking and sealing, and the denominator. It wins on busy loops because replaceable parts buy a long life. On sparse one-way lanes the crate and carton still cost less, so run the four checks before switching to a transport and storage container.
