Packaging in Water Soluble Bags
The use of water soluble bags for dispens-
ing admixtures into ready-mix trucks dates
back to the late 1980's. Fritz-Pak is the pio-
neer of this method of admixture delivery,
which allows admixtures to be added to
the ready-mix truck in concentrated pow-
dered form. Every year, more than one mil-
lion bags are produced and sold worldwide.
Fritz-Pak packages using polyvinyl alcohol
which will dissolve at low and high water
temperatures. Most bags will dissolve com-
pletely in less than one minute. The fi lm has
no effect on the concrete, especially since its
concentration in the concrete is less than one
part per million.
Advantages of Adding
Powdered Admixtures in
Water Soluble Bags
· Allows control of concrete properties at the
jobsite as well as the plant
· Not affected by freezing temperatures
· Concentrated materials not diluted with
water
· Savings in transportation costs and storage
space
· No spoilage concerns: Material stored away
from moisture remains good for years
· Easy to dose since bags are premeasured:
just count the bags, no weighing required
· 100% utilization: No material wasted in
tanks, dispensers or delivery lines
· No special handling or disposal of
containers
required
· Non-hazardous materials only are
packaged by Fritz-Pak
· Safe and easy to handle by employees
· No need of dispensers
Powders Compared to
Liquid Admixtures
Most producers today are used to seeing ad-
mixtures dispensed as liquids in plants, howev-
er, historically, most admixtures were originally
powders. There were problems in consistently
and accurately measuring the amounts to
be added because of the small dosages re-
quired. Because liquids are easier to measure
and dose than loose powders, the industry
switched from powders to liquids. The use of
water soluble bags and accurate measuring
and packaging eliminates this issue. Fritz-Pak
offers the industry all the advantages of us-
ing lightweight powders without the old
problems. The quality of our admixtures is
equal to or better than alternative liquids.
Some ready mix producers use only Fritz-Pak
powdered admixtures for the convenience
they offer. Many more use Fritz-Pak products
for special needs such as adjusting slump, air,
or set time at the jobsite, which is easy to do,
since Fritz-Pak products are compatible with
most other admixtures. Others use Fritz-Pak
admixtures in extreme conditions such as
freezing temperatures or remote locations.
Small or specialized jobs are often much bet-
ter served by using Fritz-Pak products rather
than recalibrating dispensing equipment or
upgrading it to allow for an extra admixture
in the system.
