Plastic bottle requires us to pay attention to some details before molding, especially the shape of this plastic bottle must be symmetrical. That is to say, we should try to reduce the extreme stretch points and parts as much as possible. And in all transitions, the transition of the arc needs to be adopted. So, what are the specific matters that need to be paid attention to before plastic bottles are formed?
When Taizhou Dongbang Plastic Industry Co., Ltd.
were designing the squeeze plastic bottle. The cross section of the plastic bottle needs to be a solid rectangle or an ellipse, and for a flexible plastic bottle, the cross section inside is like a circle. This makes it easier to squeeze the contents out of the plastic bottle. when blow molding. It is necessary to tend to the parts that harden first. In this way, the wall thickness of the modified part will be larger. At the edge and corner, when the parison is blown to the place where it comes into contact, the wall thickness of this part will also be smaller. Therefore, the edge of the plastic bottle and the place where the feet are ground need to be designed with rounded corners.

The heat resistance of food plastic bottles is an element we need to overcome.
