MA4020JVD1025-3
1. INTRODUCTION
The GrainPro® GrainSafe Bag™-1.0/GHF (GS Bag-1.0/GHF) is a portable bagged storage
for grain and seed, normally set-up on ground levels such as concrete pavement or
pallet. Use of a platform is also an option. It safely stores any dry agricultural commodity
at or below safe moisture content like maize, wheat, paddy, coffee, and others. It works
as a hermetic storage system (airtight) using modified atmosphere technology. It is
specially designed as a secondary packaging made from ultra-hermetic material and
zipper. Respiration of insects, microflora and commodity depletes the available oxygen
and replaces it with carbon dioxide. This conversion typically occurs within 10 days of
storage which depends on level of insect infestation. Heavier infestation results in more
rapid insect kill. The liner of GS Bag-1.0/GHF is UV-resistant, waterproof, less permeable
and resistant to rodent penetration when properly installed.
1.1. FEATURES:
1.1.1. Quality of commodity is preserved without the use of chemicals.
1.1.2. It maintains its effectiveness under adverse weather conditions.
1.1.3. It is designed for outdoor with shades/cover or indoor.
1.1.4. It can be set-up on a platform with anti-rodent protection to prevent rodent attack.
1.1.5. It is designed to store commodities up to 1 metric ton capacity based on wheat.
1.1.6. A green technology certified as safe secondary packaging for organic produce such as
grains or dried agricultural commodities.
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 GS Bag-1.0/G-HF.
1.3. COMMENTS, COMPLAINTS, AND/OR CLARIFICATIONS:
1.3.1. Please contact [email protected].
1.3.2. We shall be glad to address any of your concerns.

5. INSTALLATION
5.1 SITE SELECTION
5.1.1 In selecting a site, look for a concrete or
asphalt platform.
a. A smooth area away from standing or
running water.
b. Prepare the site by clearing away all
sharp objects (stones, broken glasses,
nails, etc.) that may puncture the GS
Bag-1.0/GHF.
c. An inspection path around the
perimeter (at least 75cm).
5.1.2 If ground will be used as flooring, put a
layer (5cm) of fine sand (or any
equivalent) on top of the soil as ground
foundation to prevent rats and termites
from damaging the bottom of GS Bag-
1.0/GHF.
5.2. LOADING
5.2.1 Check the moisture content (MC) of the
commodity to ensure commodity will be
stored at safe MC.
5.2.2 Unfold the bag and lay it out on the
prepared site. Place the empty bag on the
prepared area with the bottom stretched.

5.2.3 Loading procedure (requires at least two
people):
a. One person fills the GS Bag-1.0/GHF.
b. The second person keeps the bag open
and maintain proper arrangement of
sacks.
c. Load the bagged commodities through
the open zipper while stretching the
bag to prevent crumpling.
5.2.4 Platform positioning (if necessary):
a. Wood, bamboo, bricks or concrete can
be used to construct the platform.
Ensure that the platform is sturdy and
stable enough to take the load of the GS
Bag-1.0/GHF with the commodity.
Added protection such as mat, old sacks
or cardboard is also recommended
5.2.5. Providing cavity for CO2flushing:
a. Aligned to the inlet port, create a
cavity/canal about along the second
layers of stack.
b. This will help facilitate CO2flushing and
avoid dry ice build-up.
5.2.6.Required capacity:
a. Keep the sacks stable by loading layers
in a crisscross manner.
b. Continue piling until the desired GS Bag-
1.0/G-HF height is reached.
5.3 ZIPPING
5.3.1 Preparing to zip:
a. After the GS Bag-1.0/GHF has been filled to its recommended capacity, position
the hermetic zipper flat on top of the stack.
b. Ensure that the zipper tracks are free from dirt so that the zipping can be done
properly.

5.3.2 Using the zipper pull:
a. Starting from the end of the zipper,
place the smaller black running wheel
inside the liner facing upward to lock
the bottom liner zipper track.
b. Place the larger wheel outside the liner
facing upward to lock the top liner
zipper track.
c. Rotate the zipper pull’s plastic handle
180° toward its pulling loop, forcing the
tongues and grooves of the two zipper
tracks together.
d. Slide the zipper pull to the other entire
length of the zipper track.
e. To make zipping easier, two persons
are required. One will do the zipping
and the other will hold the other end
steadily making both sections of the
zipper in a straight line to avoid
zagging.
5.3.3 Completing the zipper process:
a. Align the marks (“triangles”) printed on
both track located above and below
zipper.
b. If a pair does not match, slide back the
zipper by pulling the top and bottom
part in opposite directions until the
marks meet.
5.3.4 Removing the zipper pull:
a. When you have zipped the entire
length of the zipper track, take the
zipper pull off the track by rotating the
plastic handle 180° away from the
zipper pull loop.
b. Close the last few centimeters of the
zipper track by manual pressing to
latched the zipper’s tongue and
groove.
5.3.5 Ensuring a complete hermetic closure:
a. Make sure to close the zipper correctly
to maintain gas-tightness.

MA4020JVD1025-3
5.4. PRESSURE DECAY TEST (PDT)
5.4.1.After completely zipping and closing,
perform a Pressure {Vacuum} Decay Test
(PDT) to ensure gas-tightness:
a. Use digital manometer.
5.4.2.Either, a commercially available or
improvised U-tube manometer can be
used to monitor the pressure.
5.4.3.Connect the manometer hose into the
flexible inlet of the GS Bag 1.0/GHF.
5.4.4. Use a vacuum pump [at least 2.3 cubic
meters per minute with 600 Watts
(0.80horsepower) centrifugal pump]:
a. Connect the vacuum pump hose to the
inlet port of the GS Bag 1.0/GHF.
b. Create at least -250 Pascals (Pa) or -25
millimeters’ water (mm H2O) vacuum.
Doing this can also help engage the zipper
tracks properly as there may be
imperfections during zipping.
c. For it to be considered sufficiently airtight, the final pressure should not be greater
than one-half (½) of the initial pressure (created by the vacuum pump) within five (5)
minutes.
d. If the PDT test failed, check for holes/tears and poorly sealed zippers then repeat the
PDT procedures.
5.5. PLATFORM INSTALLATION OF RODENT GUARD (RG)
5.5.1.For protection against rodent attacks (one
set contains 4 pieces):
a. One set can be installed on any
platform legs with leg perimeter
(round or square) of 22 cm (9'') to 44
cm (17'').
