The working efficiency of the production line is largely decided by the conveying system. When there is occasional stop on the downstream packaging system (e.g. label change), the forepart of the production line cannot be effected. At the same time, the transferring system must connect the equipment in the forepart and rear part well. Aqua Vita’s product is of good rigidity, light weight and good exchanging ability. It is applied for bottles whose diameter is 40-110 mm.
