It is important to choose the sprayer according to the features of the final product. For acidic and corrosive filling materials it is particularly important to choose appropriate materials for the sprayer and gasket. Always keep in mind the viscosity of the product as well.
You should also try to be in line with current trends, but it is more important to harmonize the colour of sprayer with the colour of the bottle.
Also consider the technical parameters of the trigger sprayer. Make sure to choose the correct neck size and dip tube length. You should also consider the usage of overcap.
