FOR AN EMERGENCY?
If you are preparing
for the possibility of a disaster in the year 2000, IMPAK is supplying
the materials necessary for long-term food and product storage.
These packets eliminate
the presence of oxygen in foodstuffs such as grain and milk powder,
ensuring long-term shelf stability. They have been used by the
US military to extend the shelf-life of bread for combat troops
to up to two years.
How does one calculate
the amount of oxygen in the container? Below are listed the volumes
(in cubic centimeters) of various containers. The most important
number to know is that, air is 20.5% oxygen.
Number 10 cans
5 gallon plastic
6 gallon plastic
There are two key
elements to keep in mind. One is the headspace
and the other is the voidspace. If
a five-gallon bucket were filled to the rim with children's marbles,
the spaces in between the marbles (void spaces) would represent
38% of the volume of the five-gallon pail (0.38 x 19,000 = 7,220
cc's). Of this number, 20.5% is oxygen.
The next item to
consider is the headspace. If you fill a number ten can to 90%
of its volume, you will have 398 cubic centimeters of headspace.
This headspace will contain 81.6 cubic centimeters of oxygen (0.205
x 398 = 81.6). In order to determine how much oxygen absorbing
capacity you require, we must determine the oxygen level in the
headspace AND the void space.
There are 231 cubic
inches in a gallon and 16.4 cubic centimeters in a cubic inch.
Oxygen absorbers are rated by their capacity to absorb oxygen
as measured in cubic centimeters.
(300's and 750's are the most commonly used sizes)
Are you packing food
in bell jars? 50 cc absorbers are perfect for this application.
your food products need desiccants?
When used in conjunction
with either a barrier bag (mylar®foil bag) or a sealed pail, there
are usually no concerns regarding moisture damage. However, some
people are very aware that the highly humid environment in which
they reside is simply "a fact of life." In this case
you may wish to use desiccant packs in the food storage container.
The desiccant packets must be placed at the bottom of the pail
or barrier bag or in the middle of the food products. The desiccant
bags must not be close to the oxygen absorbers.
Desiccants will negatively affect the performance of the oxygen
absorber when close by. We supply desiccant bags made from Tyvek.
Tyvek is a material acceptable for food product contact. We have
1 ounce and 5.5 gram packets available. The 1 ounce packets are
packaged 10 and 50 per bag. For those individuals and organizations
for which humidity is a concern, we recommend two 1 ounce packets
per 5 or 6 gallon pail, or two per large barrier bag. For some
products that are already extremely dry and for which concern
is minimal, you may use one packet.
1 oz each/50
For the smaller barrier
bags (11.75" x 15") we recommend two of the 5.5 gram
packets. Each packet is marked "1/6" on the outside.
We also recommend using one of these in cans of dehydrated foods
or moisture sensitive situations.
In the food processing
area, these bags are known as oxygen barrier bags. Many people
refer to them as mylar®foil bags because the outer layer of the
bag is mylar®foil, which is a brand name for the Dupont Corporation's
polyester film. Our mylar®foil bags are 5-layer structures of mylar®foil/polyethylene
/00035 aluminum foil adhesive/linear low-density polyethylene
(the total thickness of this material is 4.5 mils.)We have these
bags in three standard sizes:
$0.25 each; $188.00
/cs of thousand
(1-49 bags) $1.35
each; (50-249) $1.25 each: (250) $1.18 each (note: if you
order between 250 and 500 bags, you will be charged $295 ($1.18
for the 250 bags and $1.25 for each of the rest); (500) $1.10
each, (1000+)$0.99 each
x 35 1/8"
$1.55 each, in
multiples of 20
The 60NY20-35 bags
are ultra-strong, super tough, heavy-duty with nylon, and
they can be stored inside your home without a plastic pail. This
bag was designed to ship Macadamia nuts overseas.
For 15REY11-75, if you order 5,000 units or greater, it cost $388.00/K,
or 0.388 each. When purchased in conjunction with our oxygen absorbers,
20,000 mylar®foil bags will cost $315/K or slightly less than $0.32
each. If your order increase substantially, the price of 40,000
mylar®foil bags is $288.00/K. A range of food items can be packed
with a minimum two year shelf life in these bags utilizing a standard
300 cc oxygen absorber. Should you decide to go the vacuum packaging
route, you will be able to use a 200 cc oxygen absorber.
OXYGEN BARRIER BAGS
(mylar®FOIL BAGS) will greatly increase the shelf stability of
your food products. Polyethylene pails are not a true oxygen barrier
by themselves. The oxygen transmission rate is critical.
(OTR) for example, our bags have a transmission rate of 0.001
cc's of oxygen per square meter per 24 hours. A clear mylar®/poly
bag is 0.5 cc's/ square meter/ 24 hours, or 500 (FIVE HUNDRED!)
WARNING: Some companies
and people will try to tell you that clear "FOODSAVER"
bags are good for long term storage. THEY ARE NOT.(See our technical
section for details.)
do I know if I have the right
type of mylar®foil bags?
This is an extremely
good question. The mylar®foil bags that are used for long-term
food storage were originally designed for exporting Macadamia
nuts in bulk. This bag is 4.5 mils thick and appears to look like
aluminum foil. Although the mylar®foil layer is transparent, long-term
food storage bags are NEVER transparent. Another type of mylar®foil
with which many consumers are familiar is the "mylar®foil
balloon" that is often sold at supermarkets for birthdays
and other occasions. The industrial name for the mylar®foil balloon
material is metallized polyester. This is product mostly cosmetic
and has minimal oxygen barrier properties.
Any concerned individual
should be very wary of an organization trying to promote "transparent"
barrier bags or the shiny metallized polyester material as a food
storage bag. IMPAK does produce these bags for certain uses. Long-term
food storage should never be one of them and as a consumer
you have the right to a fraud claim if you have received such
information.(One good example to watch for is the US Military
MRE products. The packaging material used to produce the MREs
has a very high oxygen barrier. Often they will specify nylon
as the outside layer of the material instead of polyester (mylar®foil)
due to its stronger puncture resistance and oxygen barrier properties.)
Most of all you will never see a simple mylar®foil (transparent)
structure or shiny mylar®foil (metallized polyester) structure
used for an MRE.
is the worst that can happen
if I do not use a mylar®foil bag
inside my pail?
First the plastic
pail is not an oxygen barrier(like a #10 can) so there is a slow
transmission of oxygen through the polyethylene walls of the container
over time. According to grain processors, the most common problem
is insect infestation. Nothing will eliminate this as certainly
as an oxygen barrier bag and an oxygen absorber. Gas flushing
will always leave 2-5% oxygen minimum. Lastly, since the oxygen
absorber will actually remove 20.5 % of the air that is within
the container, it is possible for the absorber to pull in the
wall of the container (the vacuum effect) to such a degree that
the lid separates from the pail.
IMPORTANT: IF THE
LID, WHICH SHOULD HAVE A GASKET, SEPARATES FROM THE BUCKET ENOUGH
TO CREATE EVEN A VERY VERY SMALL OPENING
THIS IS WHY THE HIGH QUALITY FOOD PACKERS USE A
4.5 MIL mylar®FOIL BAG INSIDE THEIR PLASTIC PAILS THE OXYGEN
ABSORBER WILL BE DEPLETED WITHIN 72 MAXIMUM. THIS IS WHY THE HIGH
QUALITY FOOD PACKERS USE A 4.5 MIL mylar® BAG INSIDE THEIR PLASTIC
sealers are critical to provide a proper barrier to oxygen
for barrier bags. We recommend the 6-inch "constant heat"
Clam type hot jaw Unit. This unit is available for $98.50 plus
shipping. The jaws are sufficient to close any type of heat sealable
multi-layer structure. They can be used to seal the standard 20"
x 30" barrier bag used in the five-gallon pails.
You can seal bag
up to 10 inch wide, and the vacuum in fact removes enough air
to allow the use of a smaller oxygen absorbers. To guarantee a
three years minimum shelf life, we still recommend a 300 cc Oxygen

5 - 14

you to seal the bag hands-off. The item would cost as follows

TO KNOW AFTER YOU OPEN
THE OXYGEN ABSORBERS
There are several
different formulations for oxygen absorbers depending on whether
food is frozen, refrigerated or destined for long-term storage.
The most critical component for evaluation is the water activity
level (AW). All dry grain, legumes, milk powder and pasta products
have very low water activity levels. Thus, they require an oxygen
absorber which has rapid activation. These oxygen absorbers are
working within minutes of the package
being opened. When packaging food for long-term storage, you should
use the entire contents of one sealed vacuum packet bag within
30 to 60 minutes. If you know that you will be unable to use the
entire quantity, set those packets aside in a small, clean, and
dry glass jar with a secure screw-top lid. (A jam or pickle jar
will work fine.)
We also provide a
special "bag clip" (unlike any chip clip you have ever
seen) that will keep the opened oxygen absorbers pouch secure
for a minimum of three months. The clips are P/N BGCLP01 and are
much oxygen absorbent
capacity do you need for
We recommend 1500
cc's of oxygen absorbing capacity for 5 and 6 gallon pails. Thus,
you could use 5 individual 300 cc packets, or 3 individual 500
cc packets, or 2 individual 750 cc packets. If you do not need
an entire case of product, we provide individual pouches of the
300 cc packets.
you have 55 pails of food product to place into long-term storage.
You could use 165 individual 500 cc packets (3 packets/pail).
However, the 500 cc packets come 1,000/case, and at this time
we do not sell them in smaller pouches. The 300 cc packets are
150/pouch, and we can provide you with 2 pouches at $25.50/pouch.
Each pail will require 5 individual packets for a total of 275
packets. The remaining 25 packets can be stored in a sealed glass
jar for up to six months. (55 pails x 5 packets = 275 packets
For a one gallon
pail, we recommend using one 300 cc absorber. For smaller containers
(example: Mason jars) that are approximately one quart, we do
provide 50 cc absorbers. However, these are packaged 250 per pouch
with 5,400 per case. So you may wish to simply over compensate
and utilize some of your 300 cc oxygen absorbers if this is for
private use. In the future we hope to be able to provide prepackaged
pouches of 50 cc absorbers at 50 units per pouch for $9.90. Pouches
of 250 packets are available for $25.50.
