What problems should be paid attention to when making plastic bottles (2)?

(3) The printing surface of the plastic bottle is the part where consumers pay the most attention. The printing surface should be flat and continuous; if the

plastic bottle contains structures such as handles, grooves, reinforcing ribs, etc., care should be taken not to cause inconvenience to the printing operation.

The oval-shaped plastic bottle has higher rigidity, but the manufacturing cost of the mold is higher. Therefore, in order to ensure the rigidity of the plastic

bottle, in addition to selecting materials with high rigidity, the rigidity and load-resistant strength of the plastic bottle should be enhanced through the

shape design of the plastic bottle.

(4) Due to the notch sensitivity of most plastics, the plastic bottles are prone to cracks and cracks at the sharp corners, the root of the mouth thread, the

neck and other parts, so these parts should be designed with rounded corners. For the transfer point of the rectangular plastic bottle, most of the load of the

plastic bottle needs to be supported, so locally increasing the wall thickness at this point is also conducive to improving the rigidity and load-resistant

strength of the plastic bottle.
