GrainPro® Cocoon™ Cargo Instruction Manual
MA4042TSD1014-3
1. INTRODUCTION
The GrainPro® Cocoon™Cargo is designed to address the growing market demand of transporting
agricultural commodities in Big Bags (officially known as Flexible Intermediate Bulk Container or FIBC;
also called “tote bags” in the USA). Very often, commodities are infested before loading into the
container or are found to be infested upon arrival at destination ports even if they were fumigated with
phosphine prior to loading into containers.
Twenty (20) bags of 700-1000 kg or 10 bags of 1000-1500 kg fit in a standard 20-foot shipping
container. GrainPro developed a Cocoon with the same capacity as a 20-foot container that can
accommodate 20 small or 10 large Big Bags. The Cocoon Cargo zipper is located near the ground to
facilitate handling bulk with forklifts. A sturdier and more durable 1250 g/m2PVC allows for outdoor
storage which can handle extreme pressure. The Cocoon Cargo is equipped with a CO2or phosphine
treatment port and an air outlet port, which makes it ideal for fumigation.
1.1. FEATURES:
1.1.1. Easy to use and ensure the safety of all dry agricultural commodities
1.1.2. An ideal fumigation chamber for infested crops before shipment or on arrival
1.1.3. Preserves the quality (aroma, freshness, color, etc.) of the stored products
1.1.4. Ideal for organic fumigation using CO2
1.1.5. Facilitates temporary storage of goods at departure or destination ports
1.1.6. Applicable for commodities in Big Bags, but also for smaller bags with or without pallets
1.1.7. Minimizes condensation, inhibits/controls mold growth, and infestation
1.1.8. A “green” technology for organic product storage (certified safe for organic grain storage as secondary
packaging)
1.2. PRODUCT GUARANTEE:
1.2.1. In accordance with the terms and conditions herewith, GrainPro, Inc., guarantees the quality of this
product per its written warranty provided it is used according to the instructions in this manual.
1.2.2. Please read and understand the manual thoroughly before using the Cocoon Cargo.

5. INSTALLATION
5.1. SITE SELECTION
5.1.1. The Cocoon Cargo can be installed indoor or
outdoor. For indoor installation, look for:
a. A flat area away from standing or running
water.
b. Cleared of any sharp objects (stones,
broken glass, nails, etc.) that may puncture
the Cocoon.
c. Sufficient space to accommodate the
Cocoon Cargo, the GrainShade and an
inspection path around (at least 50 cm
each side).
5.1.2. If the Cocoon Cargo is going to be installed on
soil or turf, put a layer (5cm) of fine sand (or
any equivalent) on top as ground foundation.
5.1.3. During loading, make sure that workers do not
wear shoes with spikes that may damage the
Cocoon Cargo. Preferably, choose a site that
offers ease in loading/unloading, away from
crowded areas and rubbish. For indoor
installation, clean the area to remove sharp
objects.
5.2. LOADING
5.2.1. Check the moisture content of the commodity
to ensure the MC is at a safe level. (Excessive
moisture levels can lead to condensation,
mold and aflatoxin growth among others).
Safe moisture level for long term storage is
different for every commodity.

5.2.2. Loading the bottom section:
a. Unfold the bottom section of the Cocoon
Cargo and lay it out on the prepared site.
b. Roll down the wall. Stretch the floor of the
bottom section by pulling the corners
before loading the bags.
5.2.3. Start the loading of Big Bags using a
mechanical loader or a forklift.
5.2.4. Continue loading by placing the Big Bags as
close as possible to each other. Load the
second layer of Big Bags the same way as the
first layer.
5.2.5. Place desiccants (calcium chloride) bags on
strips on top.
5.3. POSITIONING THE TOP SECTION
5.3.1. Place the top section over the stack. There are several ways to place the top section:
a. By rolling.
b. By using a forklift or conveyor.

5.3.2. Unfold the top section over the stack. Make sure that top and bottom section arrows are aligned and
the tension straps are outside.
5.3.3. One pair of arrows is painted green. Match these arrows for correct front and back orientation of the
Cocoon.
5.3.4. Pull the sides covering the entire pile.
NOTE: Do not use tensions straps to pull or carry the top section.
5.3.5. Use silicon spray in closing the Cocoon with zipper pull.
5.4. USE OF DESICCANT (CALCIUM CHLORIDE, CaCl2) –(Recommended)
5.4.1. Required dosage of Calcium Chloride, CalCl2:
5.4.2. Place the desiccants (Calcium Chloride, CaCl2) at the middle-top portion of the bags inside the
Cocoon Cargo before zipping.
5.4.3. For six (6) months of storage, spread-out the desiccant packs on top portion of the bags inside the
Cocoon Cargo before Zipping.

5.5. ZIPPING
5.5.1. Preparing to zip:
a. Insert one hand inside the inverted pocket
and engage the zipper track of the top and
bottom liners by pressing the zipper.
b. Manually close the zipper track to a length
of 10 cm before using the zipper pulls.
NOTE:
There are zipper pulls that zip to the right for right-handed users *marked with “RIGHT”+ and
zipper pulls that zip to the left for left-handed users *marked with “LEFT”+.
5.5.2. Engaging the zipper pull:
a. Open the zipper pull by moving the black
plastic handle, projecting the large wheel
away from the flexible pulling loop.

10/24
GrainPro® Cocoon™ Cargo Instruction Manual
MA4042TSD1014-3
b. Starting from the inverted pocket, place
the smaller black running wheel inside the
liner facing upward to engage the zipper
track of the bottom liner.
c. Place the larger wheel outside the liner
facing upward, to engage the zipper track
of the top liner.
5.5.3. Using the zipper pull:
a. Rotate the zipper pull’s plastic handle 180°
toward its pulling loop, forcing the tongues
and grooves of the two zipper tracks
together. Slide the zipper pull around your
Cocoon Cargo.
b. To make zipping easier, a second person
should pull the top and bottom liners’
zipper tracks close to each other as the
zipper pull is advancing.
c. Apply the silicon spray to the zipper track
to ensure ease of pulling the zipper pull.
5.5.4. Completing the zipping process:
a. Take note of the marks (“arrows”) printed
on both top and bottom sections in pairs.
b. The markings at the top section are located
on the protective flap. If you reach a pair
that does not match, you can slide the
already zipped tracks by pulling the top
and bottom liners in opposite directions
until the marks meet.
NOTES:
If marks do not align, the two zippers may have been exposed to different temperatures which
might result in elongation of the zipper.
Expose the Cocoon sections under the sun for 30 minutes to remove zipper length difference.
