The roll-packed mattress is the export mattress in its most dense form, and the density is the freight saving made physical. The mattress compresses to the fraction of its height, rolls into the compact cylinder and fits the container at the density the ocean freight rewards, so the same container carries the mattress at the much lower cost per unit; the roll pack is the volume reduction turned into money. The freight math is the decision tool: the container cost is the fixed number, the units per container are the variable and the cost per unit falls as the density rises, so the roll-packed mattress at the 400 units per 40HQ container ships at the fraction of the uncompressed cost; the 70% saving is the density math. The packing line is the delivery mechanism: the compression and rolling machine turns each mattress into the tight roll at the machine pace, the folding machine handles the thick units and the automatic packing line wraps the finished units, and the line that packs at the high density delivers the container plan; the machine fit is the second half of the freight saving. This guide walks the volume math, the container plan, the 70% breakdown and the machine cases. The IF-CR8 Automatic Compression & Roll Packing Machine, the IF-CR9 Folding and Roll Packing Machine and the IF-AMB Automatic Mattress Packing Machine are the machine cases this guide maps.
The freight question starts with what the ocean freight actually charges, and the ocean freight is the container math, not the weight math for most mattress loads. The 40HQ container is the standard export box: the interior volume is fixed at about 76 cubic meters, the usable space after the pallets and the aisles is the real budget and the freight rate applies to the container as the whole unit, so the cost per mattress is the container rate divided by the units that fit; the container is the fixed cost. The uncompressed mattress is the density problem: the typical queen mattress in the flat form takes the volume that limits the container to the 80 to 100 units, the air inside the mattress is the cargo and the container that loads the flat mattresses pays the freight for the mostly empty box; the flat form is the freight waste. The roll pack is the density fix: the compressed mattress rolls to the fraction of its height, the air is pressed out and the compact roll stacks in the container grid, so the same 40HQ container loads the 300 to 400 units and the cost per unit falls to the fraction; the roll pack is the volume reduction made shippable. The 70% saving is the arithmetic: the container rate is the same, the units per container multiply and the cost per mattress drops by the 60 to 75 percent depending on the mattress height and the roll diameter, so the roll-pack saving is the density math applied to the freight bill; the saving is the reason the export mattress ships rolled.
The table is the freight map: the container is the fixed cost, the roll pack multiplies the units and the cost per unit falls with the density.
The volume math is where the freight saving becomes the numbers the export manager can plan, and the math runs from the mattress volume to the roll volume. The mattress volume is the first number: the queen mattress at the 200 by 150 by 25 centimeters holds the 0.75 cubic meters in the flat form, the air fills most of that box and the container budget is spent on the air, so the flat mattress is the volume hog of the export load; the flat form is the baseline. The compression is the second number: the press squeezes the mattress to the fraction of its height, the spring unit compresses to the 5 to 8 percent of the original volume, the foam unit compresses to the similar ratio and the compressed slab is the small footprint ready for the roll; the compression is the volume cut. The roll is the third number: the compressed mattress rolls into the cylinder at the 30 to 40 centimeters in the diameter, the roll length follows the mattress width and the compact cylinder stacks in the container grid with the minimal air between the units, so the 0.75 cubic meters of the flat mattress becomes the 0.10 to 0.15 cubic meters of the roll; the roll is the final density. The container plan is the fourth number: the 40HQ container at the 76 cubic meters of the theoretical volume loads the 300 to 400 rolled units against the 80 to 100 flat units, the plan accounts for the roll stacking pattern and the load securement and the 400-unit target is the realistic high plan for the standard queen line; the plan is the freight saving realized.
Flat mattress: the queen unit holds about 0.75 m3 in the flat form with the air as the cargo | Compressed slab: the press squeezes the unit to the 5-8% of the original volume | Compact roll: the cylinder at 30-40 cm diameter takes the 0.10-0.15 m3 per unit | Container plan: the 40HQ loads the 300-400 rolled units against the 80-100 flat units
The 70% breakdown shows where the freight saving appears on the bill, and the saving splits across the ocean leg, the inland leg and the unit economics. The ocean leg is the largest share: the ocean freight charges per container, the container with the 400 rolled units spreads the rate across the four times the units and the per-unit ocean cost falls by the 70 percent against the flat-load container, so the ocean leg is where the roll pack pays first; the sea is the biggest cut. The inland leg is the second share: the truck and the rail charge per container or per load, the dense container moves the same trailer for the four times the units and the inland cost per unit falls with the same multiplier, so the roll pack cuts the land leg by the similar percentage; the inland leg doubles the saving. The unit economics are the third share: the mattress that ships at the lower cost per unit opens the new markets where the freight made the price uncompetitive, the 70% saving moves the price point and the volume follows, so the freight math is also the market math; the saving is the growth lever. The packing cost is the offset: the roll-pack line adds the machine cost and the film cost per unit, the offset runs the 8 to 12 percent of the flat freight bill and the net saving stays at the 60 to 65 percent, so the honest number is the gross 70% minus the packing cost; the net saving is the number the export manager plans with.
The machine fit matches the packing line to the density plan, and the fit covers the three cases of the export packing hall. The compression and rolling machine is the density case: the IF-CR8 integrates the sealing, the compressing and the rolling in one machine, the unit enters the mattress form and exits the compact roll at the rated pace, and the single-machine flow delivers the highest packing density for the standard mattress line; the IF-CR8 is the mainline case. The folding machine is the thick-unit case: the IF-CR9 presses with the 100-ton press and folds the thick mattresses up to the 450 millimeters before the rolling, so the thick comfort units that cannot roll straight still reach the dense roll, and the fold machine keeps the thick line inside the container plan; the IF-CR9 is the thick case. The automatic packing machine is the end-of-line case: the IF-AMB wraps the finished unit into the protective film at the end of the line, the film protects the roll through the container and the automatic wrap keeps the packing pace with the line, so the density plan starts at the final station where the unit leaves the line; the IF-AMB is the finish case. The fit also covers the line integration: the compression machine feeds the rolls, the folding machine handles the thick units and the wrapping station finishes the packets, and the three stations share the roll standard and the container plan; the fit is the compression, the fold and the wrap, and the matched line delivers the 400-unit container to the port.
The density protocol delivers the 400-unit container in six steps, run on the export packing floor and tuned by the container plan. Step 1: the product check, measuring the mattress height and the roll diameter on the sample, confirming the roll fits the container grid and logging the density per product line; the product check sets the plan. Step 2: the compression setting, adjusting the press pressure and the dwell time per mattress type, confirming the unit returns to the shape and recording the compression ratio per line; the compression setting is the density driver. Step 3: the roll setting, confirming the roll diameter and the film wrap on the sample, checking the seal strength and the vacuum hold and adjusting the parameters per product; the roll setting locks the container grid. Step 4: the container plan, mapping the roll stacking pattern, the load securement and the unit count per 40HQ, verifying the plan against the actual rolls and updating the plan per product mix; the container plan is the freight math made real. Step 5: the line pace, running the compression, the fold and the wrap at the rated speed, confirming the packing pace matches the production pace and the stacker clears the line; the line pace delivers the plan on the schedule. Step 6: the review, tracking the units per container, the cost per unit and the returns per batch against the baseline and adjusting the parameters and the plan by the data; the review keeps the export line at the high density, and the line that holds the density ships the 400-unit container at the 70% saving every voyage of the season.
