| Because most plastics have notch sensitivity and are prone to loopholes and cracking, plastic bottles should be rounded at the corners, the roots of the mouth threads, and the neck.
For the transfer of rectangular plastic bottles, it is necessary to support most of the load of the plastic bottles, thus increasing the wall thickness of the place, and the consumer's attention will meet these parts, which is beneficial to improve the rigidity and load resistance of the plastic bottles. The printing details should be flat and continuous; if the plastic bottle contains handles, grooves, ribs, etc., the printed surface of the medicinal plastic bottle. When trimming, we should pay attention to the inconvenience caused by printing. Elliptical plastic bottles have higher stiffness, but the cost of making the mold is higher. Therefore, in order to ensure the rigidity of the plastic bottle, in addition to determining the material with high rigidity, it is also necessary to determine the shape of the plastic bottle to enhance the rigidity and load resistance of the medicinal plastic bottle.
If the middle part of the medicinal plastic bottle is relatively thin, the edge and the corner of the plastic bottle should be trimmed into rounded corners. Change the specific shape of the plastic bottle and increase the basic groove or rib of the plastic bottle to improve the rigidity and bending resistance of the plastic bottle. Longitudinal grooves or ribs eliminate the offset, sagging or deformation of the plastic bottle under long-term load. The detailed environmental conditions of medicinal plastic bottles must be controlled and applied according to the corresponding scale situation, and the control and application should be implemented according to the corresponding construction scale.
The flatness and details will be adjusted accordingly. The process of trimming and utilizing medicinal plastic bottles must be carried out according to certain scale and shape characteristics. Enrichment prompts good elegance and planning, with the first innovative features. When accepting the label of the medicinal plastic bottle, the label surface should be flat. A “frame” can be trimmed in the plastic bottle to make the label accurately positioned and not moved to produce movement. In blow molding, the parison inflates the area where the snoring starts, and tends to soften the part first. Therefore, the wall thickness of this part is also larger. At the edge and the corner, the parison is inflated at the end of the snoring, and the wall thickness of the portion is small.
