4. Easy handling-the brick shape box shape is easy to palletizing.
5.Quality control of 25kg 50kg kraft paper plastic pp woven composite porland cement bags/sack:
In order to produce the high quality Ad*Starkon block bottom valve bags, the following is our effort to control quality:
1. From material: using 100% original high strength pp material. not recycled or wasted pp material.
2. For fabric: control the strength tensile and density of pp tapes to satisfy the loading capacity.
3. Inspection: using the machines to test the strength tensile and tearing function after finish the goods.
4.Drop test: for safe factor, for each batch of products, will test the air permeability.
Cemend bag transportation
For automatic filing machines , the bags must keep To be smooth and unfolded , so We have the following packing term , please check according To your filling machines .
1. Bales packing : free of charge , workable for semi-automatization filing machines , workers hands are needed when packing cement .
2. Wooden pallets : 25$/set, common packing term , convenient To loading by forklift and could keep the bags flat , workable forcompleted automatic filing machines To large production , but loading few than bales , so higher transportation cost than bales packing .
3. Cases : 40$/set, workable for packages , which has highest requirement for flat , packing the least quantity in all packing terms , with the highest cost in transportation .
4. double planks: workable for railway transportation , could add more bags , reducing empty space , but it is dangerous for workers when loading and unloading by forklift , please consider second .
