In the process of producing health care products plastic bottles, in order to make the wall thickness of the bottle uniform, the symmetry of the shape should be injected. During the blow molding, the part where the parison first contacts, always tends to harden first, so the The wall thickness of the part is also larger. The edge and corner part is the last contact part of the parison inflated, and the wall thickness of this part is small. Reduce extreme stretch points and parts as much as possible, and adopt arc transitions at all transitions.


Changing the surface shape of the health product plastic bottle, for example, the middle part of the health product plastic bottle is relatively thinner, and increasing the circumferential groove or rib on the surface of the health product plastic bottle can improve the rigidity and bending resistance of the health product plastic bottle. The longitudinal grooves or reinforcing ribs can eliminate the deviation, sagging or deformation of the health care plastic bottle under long-term load.

The elliptical health product plastic bottle has higher rigidity, but the manufacturing cost of the mold is higher. Therefore, in order to ensure the rigidity of the health care product plastic bottle, in addition to selecting high-rigidity materials, the shape design of the health care product plastic bottle must be used to enhance the rigidity and load-bearing strength of the health care product plastic bottle. When designing squeezed health product plastic bottles, if the material is high-density polyethylene or polypropylene.


The cross-section of the plastic bottle should be rectangular or oval. For plastic bottles made of low-density polyethylene or other flexible health care products, the cross-section should be round.


The printing surface of the health product plastic bottle is the most concentrated part of consumers. The printing surface should be flat and continuous; if the health care product plastic bottle contains handles, grooves, ribs and other structures, the design should be careful not to cause inconvenience to the printing operation. If labels are used on the surface of health care products plastic bottles, the labeling surface should be flat.
