    Comparison of different material cement bag

    kraft paper bag laminated

    polyproprpene woven bag

    1 moisture- proof Strong moisture absorption, water

    permeates layer by layer, deformation after wetting, high

    requirement for stacking Isolated from moisture

    erosion in normal temperature, water absorption below 0.01%

    in 24 hours, low moisture permeability

    2 Environmental Protection 24 trees was logged

    for making 1 ton of paper 8- 20 tons of water was consumed

    for 1 ton of paper with subsequent severe water pollution

    Byproduct of crude oil refining

    100% recyclable few water

    demand in manufacture, maily recycling water

    3 cost 1. manufacture: large water consumption

    2. wastewater handling: should be processed by special

    apparatus, increasing expenditure and energy consumption

    3. logistics: nearly twice heavier than laminated woven bag,

    uneconomical cost in transportation

    4. recycling: same procee with manufacture with large water

    consumption, high resources cost and heavy pollution, increase

    wastewater handling cost. recycling less than

    5. procurement cost: higher unit price than laminated woven

    bag 1. manufacture: few water consumption, bare pollutant

    2. logistics: nearly twice lighter than kraft paper bag, cost-

    effectiveness in transportation

    3. recycling: recycling used bags for direct re- use, recycling

    more than 6 times, energy- saving to the maximum

    4. procurement cost: relatively lower unit price than kraft

    paper bag

    4 strength easily to be broken while drop test

    or unloading if the paper sizes are not uniform through

    multiple layer high elongation and strength of

    weft and warp

    5 Tear and wear resistance high friction

    between bags in stacking with only about 0.12 rub

    coefficient between pp woven bags, convenient for unloading

    6 resycling could be recycled about 3

    times, functionality decreases with increasing recyling times

    recycling rate is 21% simple recycling

    process, energy- saving, recycling more than 6 times

    no limites for recycling times, few influence in

    functionality

    high recycling rate

    conclusion: To sum up, laminated PP woven bas has huge

    advantages in comprehensive use.

    ① For functionality, it is of high strength and elongation

    and low rate of broken bags

    ② For cost control, it is of low energy consumption and low

    recycling cost, besides in logistics expenditure, it is cost-

    effective. With same amount, the weight of plastic woven bags

    is much lighter than kraftpaper bags. And the unit price of

    laminated woven bag is at less 10% lower than kraft paper

    bag.

    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

    packaging.

    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

    China market.

    Plastic woven bags have already displaced traditional cement

    packaging materials in many countries, and keep an

    optimistic growth globally in years. The demand for it would

    be increase according to estimated due to lots of

    construction projects and infrastructures are planned to be

    commenced in recent years.
