The long-rod spray pump has relatively high requirements on the manufacturer, because the spray pump is prone to some problems.
First, the spray is uneven, the use is discounted, and it is very inconvenient to use.
Second, it is easy to damage, and it cannot be sprayed after spraying several times, which affects the later use.
Third, the poor sealing of the spray bottle will affect the quality of the packaged product. The tightness of the bottle body and the cap, and the water vapor permeability. Sealing and water vapor permeability are two important technical indicators of spray bottles.
