History of cement package from wooden casks to final
Polypropylene woven bag. Because of PP cement bag’s
advantages; PP cement bag is the future trend in cement
Imported cement was packaged in wooden casks11, each
containing 3 bushels12, about 4 to 4.25 cubic feet ( about
170 kg net) depending upon the fineness of the cement.
Cement produced in Australia was initially supplied in
similar sized wooden casks ( C& CA 1928) . Later cement was
supplied in jute bags of 125lb. ( 56.7 kg) ( Penn 1977) , as
well as wooden casks and light gauge steel drums of 400 lbs
gross ( 375 lb. net) for export ( Commonwealth 1904) . In 1906,
steel drums, semi- circular in cross section and equal to half
a normal drum, . were designed to supply remote area by camel
transportation. The jute bags proved to be to dusty leading
to a docker strike. Paper lined jute bags were developed
which led to the present multi- walled paper bag. When cement
in paper bags was introduced, it sold at 127 pounds gross
and 125 pounds net per bag.
Polypropylene was first polymerized to a crystalline
isotactic polymer by Giulio Natta as well as by the German
chemist Karl Rehn in March 1954. [ 4] This pioneering
discovery led to large- scale commercial production of
isotactic polypropylene by the Italian firm Montecatini from
1957 onwards. [ 5] Syndiotactic polypropylene was also first
synthesized by Natta and his coworkers.
In china, paper cement bag have the whole market before
80’s. In 80’s, PP woven bag is used in cement packaging,
and be in a rapid development This bag has a defect. That is
easy to be dusty. We improved the design. Final laminated
polypropylene woven bag came. It is accepted by whole
market. And Chinese government set a policy to forbid the pp
woven bag without lamination in 90’s.
Laminated pp woven bag is Durable and hard to break, Light
Weight so can save the freight for transfer, Moisture /
Water Resistant, not easy to take dust and Reusable. PP
cement bag is low cost and high price- quality ratio. The raw
material is get from oil and it is environmental- friendly.
So laminated pp woven bag is the first selection for cement
packaging. It dominates the Chinese market.
History of plastic woven bag
In 1930s, H•Jaeque invented a new technology to make cut
cellosilk and split- film fiber through his study of PVC. In
1950s, O•B•Rasmussen used extruded film and drawing machine,
invented the fiber for weaving. And in 1965, uniaxial
oriented filament was put into mass production in Europe to
manufacture woven bags for industrial packaging.
Cement was initially packaged in wooden casks, later changed
to jute bags, which proved to be dusty. Therefore paper bags
were developed. Plastic woven bags were invented in 1950s,
main components were polyethylene, polypropylene and their
composites. Plastic woven bag was used in cement packaging
in early 1980s. In the middle of 1980s, paper bags were in
short supply; plastic woven bags gradually got prevailed and
became the main trends for cement packaging. Plastic woven
bag is in constant improvement to meet the increasing
performance requirements met in practical use. During
decades of development, laminated plastic woven bags are the
most universal packaging material in cement industry in many
countries, for example, plastics woven bags dominate the
