Advantages and disadvantages of plastic bottles
Comprehensive analysis of the advantages and disadvantages of plastic bottles In our lives, we can see plastic bottles everywhere. In the face of the assortment of plastic bottles, how to distinguish the advantages and disadvantages of plastic bottles, I will give you a detailed introduction to this problem.
1. The one-step blown plastic bottle has less mechanical scars, good air tightness between the bottle mouth and the bottle cap, a small leakage and water leakage ratio, extremely high transparency, and beautiful appearance. The biggest technical problem is that it is not easy to control the uniformity of the bottle wall, the thickness difference is large, and it is easy to produce convex deformation.
2. The plastic bottle blown by the two-step method has more mechanical wound marks, and the transparency is slightly worse than the one-step method. The two-step method blows plastic bottles. The preforms are first pre-molded and shaped by injection molding, and then sent to the next step for secondary heating and blowing. The bottle preform is inevitably mechanically traumatized during the conveying process of the hopper and stored in the warehouse, and the preform and the mouth of the preform are damaged by the friction of the preform. Therefore, the air tightness of the cap and the mouth of the bottle is poor, and the air leakage rate is better than the one-step method Blowing should be high. The advantage is that the bottles blown out by this technology are tested with an ultrasonic thickness gauge. The walls of these bottles are uniform, and the thickness error is small. It is not easy to produce convex deformation after filling beer beverages.
