Understanding trigger sprayer requirements helps plant managers and buyers make confident equipment decisions. This guide summarizes practical criteria aligned with current industry practice.
Match Neck Finish to Your Bottle
Trigger sprayers must mate precisely with 28/400, 28/410, or 28/415 neck finishes. Mismatch causes leaks and poor actuation force — verify bottle and sprayer drawings together.
Output and Spray Pattern
Personal care cleaners often need 0.9–1.3 mL per stroke with adjustable nozzle from spray to stream. Fine mist heads suit hair leave-in products; foam triggers work for specialty bathroom formats.
Chemical Compatibility
Test dip tube material (PP, LDPE) against surfactants, solvents, and essential oils. Long-term storage tests prevent creep, cracking, or discoloration on shelf.
Child-Resistant and Sustainability
CR triggers meet household chemical regulations. PCR resin options and all-plastic shrouds support brand sustainability claims without sacrificing function.
Frequently Asked Questions
What is the most common trigger size?
28/410 is widely used for 500 mL–1 L household and personal care bottles.
Can triggers ship pre-assembled?
Yes — factory assembly with torque and leak testing reduces filling line labor.
How to sample before bulk order?
Request 50–100 pcs for line trials including drop and pump cycle tests.
