| 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. | |||
