The trigger sprayer is a red and white PP plastic 28-400 on/off nozzle trigger sprayer with 9.25 inch dip tube (1.3 cc output). This trigger sprayer has been equipped with a nozzle with two settings: on and off. Polypropylene (PP) is marked with the resin identification code of 5. PP is less flexible than LDPE, somewhat stiffer than other plastics, reasonably economical, and can be translucent, opaque, or of any color. PP has very good resistance to fatigue, and has an extremely high melting point (320 degrees Fahrenheit or 160 degrees Celsius). This closure fits a container with a 28-400 neck finish.
