The shape of the plastic bottle should be symmetrical. Minimize extreme stretching points and parts. Arc transitions are used at all transitions.
1 Make the plastic bottle wall thickness uniform.
The most concentrated part of the consumer's attention. The printed appearance should be flat and continuous; if the liquid plastic bottle contains handles, grooves, ribs, etc.
2 The printed surface of the plastic bottle. Care should be taken during design to avoid inconvenience to the printing operation.
The label surface should be flat. A “frame†can be designed on the exterior of the plastic bottle to accurately position the label.
3 When the appearance of the plastic bottle is marked. Does not produce movement.
If the middle of the plastic bottle is relatively thin,
4 Change the shape of the plastic bottle. Increasing the circumferential groove or rib of the outer surface of the plastic bottle can increase the rigidity and bending resistance of the plastic bottle. Longitudinal grooves or ribs eliminate the offset, sagging or deformation of the plastic bottle under temporary load.
If the material is high density polyethylene or polypropylene,
5 When designing extruded plastic bottles. The cross section of the plastic bottle should be rectangular or elliptical. For low density polyethylene or other flexible plastic bottles, the cross section is preferably round. This facilitates the extrusion of the contents from the plastic bottle. The part of the parison that is inflated first,
6 When blow molding. Always tend to harden the area first. Therefore, the wall thickness of this part is also larger. At the edge and the corner, the final contact of the parison is inflated, and the wall thickness of the portion is small. Therefore, the edges and horns of the plastic bottle should be designed to be rounded.
