1. The wall thickness of the plastic bottle is uniform, the part where consumers pay the most attention. The printed surface should be smooth and continuous; if the liquid plastic bottle contains handles, grooves, ribs and other structures,
2. When designing the printing surface of the plastic bottle, care should be taken not to cause any inconvenience to the printing operation. The label surface should be flat. A "frame" can be designed on the outside of the plastic bottle to make the label position accurately,
3. When using labels on the exterior of the plastic bottle, no movement occurs. For example, the middle part of the plastic bottle is relatively thinner.
4. Changing the outer shape of the plastic bottle and increasing the circumferential groove or rib on the outer surface of the plastic bottle can improve the rigidity and bending resistance of the plastic bottle. The longitudinal grooves or ribs can eliminate the deviation, sagging or deformation of the plastic bottle under temporary load.
