Tin pack factory direct sale, support, free sample with iron straps advantages: 1. Selection of high quality steel, strong tension; 2. Tin pack material evenly; 3. The operation is simple, easy packing, anyone can operate; 4. Belt edge collapse, edge smooth and no burr, not prick the hand; 5. Iron straps spit oil, not easy to rust. Iron straps production packing is one of the key, with calcium carbonate as the inorganic filler used in plastic filling to reduce the cost of the products has many years of history, and received good results. Therefore has been widely used in many industries. Calcium carbonate is added in the plastic, the more the lower the costs will drop too. Calcium carbonate is certainly not an unlimited added, considering the plastic toughness of manufactured goods, calcium carbonate filler dosage general control within 50 wt %. Found by lots of experiments, fill a lot of superfine calcium carbonate in the plastic particles, plastic not only intact rigidity, toughness have been improved greatly, can improve the biggest 2 ~ 3 times. But this kind of the high cost of superfine calcium carbonate particles, but as a filling material to put into production, can change the past filled plastic must be carried at the cost of some mechanical properties, mechanical properties of modified plastic along with the increase of filler filling volume decline.
