GANGLONG Package materials
At present, as a result of one-sided pursuit of low-cost manufacturer, the production of some packing belts In the domestic market, process in large-scale use of waste materials and calcium carbonate, barite powder is also a largen urn bet of incorporation to increase the weight of paper core and some even up to 3 kg, by doing this to increase the unit weight to reduce the cost of production; because in the domestic market the price of packing belts is based on the weight of them, But this kind of packing belts are with the following issues,
1, A large number of calcium carbonate and raw materials used cause strength of it greatly reduced, fn particular the strength of bonding point is even worse, resulting in fragile packaging, packaging waste, and fracture phenomenon in the course of recurrent Yushulin, which cannot meet the security requirements.
2, As a result of heterogeneous composition, impurities, and can not be recycle, not only a waste of resources but also pollution of the environment
3, In order to increase the strength of PP belt, it is inevitable to increase in the thickness of PP, while the increase in thickness is greatly reduced flexibility, in order to increase the flexibility with PP, it turns out to add a large number of calcium carbonate,which makes further PP with an increase of surface roughness, thereby seriously wear parts balers, balers sherten life.
4, In the use, there are many problems of this kind of packing belts ,sued as not sending tapes, or not in place, not to reclaim belt or strapping is not tig ht, which cause a serious waste of materials and significant inefficiency, which actually increase the cost
Changing the traditional concept of Calculation method and the introducing new practical
How to calculate the price of packing belts per volume? Domestic traditional method of calculation is
The price(yuan) per vole = the price per kilogram (yuan) x weight per volume (kg)
We believe that: first of all, there Is great difference of ratio of raw materials used among manufacturers, which turns out to the d ramatically difference of the products; secondly, the use u nit of packing belts is length, not weight, so use weight as a unit of pricing is inappropriate. In accordance with internat~ona~ practice, the price of packing belts we produce, is caloulated this way:
The prloe of each volume =the price per meter (yuan) x the length of each volume (m)
