Matters needing attention during the use of plastic bottles

1. Change the surface shape of the plastic bottle, such as the middle of the plastic bottle is relatively thin, and increase the circumferential groove or rib on the surface of the plastic bottle, which can improve the stiffness and bending resistance of the plastic bottle. Longitudinal grooves or ribs can eliminate the deviation, sagging or deformation of the plastic bottle under long-term load.

2. When designing extruded plastic bottles, if the material is high-density polyethylene or polypropylene, the cross-section of the plastic bottle should be rectangular or oval. For low-density polyethylene or other flexible plastic bottles, the cross-section should be circular. This facilitates the extrusion of the contents from the plastic bottle.

3. In order to make the wall thickness of the plastic bottle uniform, it should be noted that the shape of the plastic bottle should be symmetrical. Minimize extreme stretch points and parts. Arc transitions are used at all transitions.

4. 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 handles, grooves, ribs and other structures, care should be taken not to cause inconvenience to the printing operation when designing.
