Can we skip the pallet and ship Case Export Packaging in cartons only?

You save about $11 per unit, but handling goes from 1 lift to 20, and damage eats that saving.

How do I judge edge crush in a minute?

Pinch a vertical corner. Resistance with spring-back means the board is near 32 lb/in; if it folds, it will not hold three layers.

How much desiccant does Case Export Packaging need?

Size by volume: 16 units of 125 g per 20 cubic metres, 24 past 30 days. Extra does no harm; too little changes nothing.

EPE or moulded pulp for the foam?

Below 12 kg with a simple shape, 20 mm EPE costs less. Sharp corners take moulded pulp: better fit, $8000 in tooling.

Can a wrongly placed label be reworked?

Before the film goes on, yes. Peeling through film fuzzes the carton surface, so the carton is replaced: about 3 minutes each.

What Five Bench Measurements Reveal About Case Export Packaging

Quick answer: Case Export Packaging can be judged without opening a carton. Five bench measurements — inner clearance, foam thickness, pallet overhang, stack height, film layers — against three pass lines settle a batch in about 10 minutes.

FAQ

1. Case Export Packaging Starts With Three Bench Measurements

A finished case sits on the sampling bench beside a flat-packed carton. The inspector does not reach for a knife: the case goes in, and a hand slides along four sides to feel movement. Movement means clearance; none means squeeze. That gesture tells whether Case Export Packaging was built around the case profile or forced into a generic carton.

The pass line is 8 mm per side. Under 5 mm, the latch presses the flap and one night under load lifts it; over 15 mm, a drop drives a corner into the wall. Overhang comes next, held to 10 mm per side.

Measure	Pass line	Check first if it fails
Inner clearance, each side	8 mm, inside 5 to 15 mm	Whether both drawings share one revision
Flap gap	3 mm or less	Score position and flute direction
Pallet overhang	10 mm or less	Placement error or wrong pallet
Stack height	1.6 m or less	Layer count and layer height

2. Edge Crush and Foam: Working Back From a 12 kg Case

Twelve kilograms divides the spec in Case Export Packaging. Under 12 kg gross, five-wall AB flute at 32 lb/in edge crush, 5.6 kN/m, carries three layers; 12 to 25 kg needs 40 lb/in and a 9 mm wall. A weak board fails on the third layer after 48 hours, at the port.

Foam follows drop height, not feel. EPE at 30x expansion and 20 mm compresses 3 mm under 12 kg and absorbs a 600 mm drop; at 10 mm, one drop marks the shell edge.

Gross weight	Flute and wall	Crush	Foam	Drop
Under 6 kg	3-wall B, 4 mm	26 lb/in	15 mm	800 mm
6 to 12 kg	5-wall AB, 7 mm	32 lb/in	20 mm	600 mm
12 to 25 kg	5-wall BC, 9 mm	40 lb/in	25 mm	500 mm
Over 25 kg	7-wall AAA, 12 mm	48 lb/in	30 mm	400 mm

3. Pallets and Stack Height: 10 mm of Overhang Is a Defect

The standard export pallet runs 1200 x 1000 mm, deck 22 mm, blocks 100 mm, rated 1000 kg dynamic. Whether a case outline divides into that deck decides units per layer: 400 x 300 mm fits 10, while 420 x 310 mm takes 8 and leaves a 100 mm strip for angle board.

Height in Case Export Packaging works back from the stack. A 480 mm carton gives 1.59 m at three layers with the 150 mm pallet, inside the 1.6 m line; a fourth layer passes 2 m and stops clearing a side door. Centre of gravity more than 50 mm off centre loads four slings 30% unevenly.

Case outline	Per layer	Layers	Height	Gross
400 x 300 mm	10	3	1.59 m	385 kg
500 x 400 mm	6	3	1.56 m	349 kg
700 x 500 mm	4	2	1.35 m	201 kg

4. Film, Desiccant and Heat Inside the Box

Six wraps at 50% overlap suit Case Export Packaging that spends 30 days at sea. A 25 micron LLDPE film stretched 250% turns 1 m into 3.5 m. A 16 mm PP strap rated 1600 N goes on at 350 N, at 100 mm and 400 mm above the deck.

Inside, a 40 ft sea box on deck reaches 60 C at 90% humidity, and the walls condense once night air cools them. Board moisture climbs from 8% to 14% and edge crush drops 40%, so 385 kg rests on the bottom carton. Desiccant runs 16 units of 125 g per 20 cubic metres, raised to 24 past 30 days. Staining, swollen sachets or tacky foam mean a rebuild at 90 minutes per pallet.

5. Marks and Labels: 20 mm Off Means Another Inspection

A 100 x 100 mm label for Case Export Packaging sits on the front and one side, 50 mm below the top edge and 20 mm in from the corner. Over the corner, film creases it, the barcode grade falls from A to C, and the scanner needs 3 passes. Marks carry consignee, carton number, gross and net weight; a hand-corrected one can hold a shipment 2 days.

6. Four Numbers on the Quotation Reveal Fit

For one 400 x 300 mm case in three layers, the carton is $6.5, foam $3.2, angle board $0.6, film and strap $1.4 — $11.7, about 4% of ex-works price. A quote under $8 usually means one flute grade down, or foam cut from 20 mm to 12 mm.

Minimum order, sampling and tooling ownership say more than price. Cartons start at 200 pieces; foam tooling is $8000, samples 7 days, production 25 days. A supplier quoting 100 pieces at the same price runs a borrowed die that cannot be revised when the shell changes.

Item	Ask	Warning sign
Carton	Edge crush in lb/in	No board grade quoted
Foam	30x or 25x	Says 20 mm, measures 12 mm
Sampling	Fee offsets order	3 days, no approval sheet
Tooling	Who owns it	Vague joint ownership

Conclusion

Five numbers decide how Case Export Packaging performs: 8 mm of clearance, 3 mm of flap gap, 10 mm of overhang, a 1.6 m stack, 6 film layers. Ten minutes of measuring before price talks saves 20 cartons of rework over 2. Written into the inspection sheet, they turn Case Export Packaging into something a buyer checks instead of trusts.
