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.
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. 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.
