The mini trigger sprayer ubiquitous across multiple plastic bottle packaging formats. Below are the most common use cases:
1. Face & Body Mists (PET / PP Bottles)
Product examples: Rose water mist, thermal spring water, setting spray
Why this spray head: Requires ultra-fine, silent spray without “spitting.” A 0.12 ml output with 35 µm droplet size leaves no residue.
Bottle compatibility: 24/410, 28/400 neck finish (standard cosmetic threads)
2. Leave-In Hair Treatments (HDPE / PCR Bottles)
Product examples: Detangling sprays, scalp tonics, UV protection mists
Why this spray head: Wide spray cone angle (40-60°) covers larger surface area; dip tube reaches bottom of tall HDPE bottles.
3. Perfume & Body Splash (Glass / Thick-walled PET)
Product examples: Eau de toilette samples, body splash for travel
4. Aerosol-Like Continuous Sprays (With Bag-on-Valve Technology)
Product examples: 70% ethanol-based sanitizer in pocket-size bottles (30–50 ml)
Why this spray head: Requires alcohol-resistant seals (FFKM or modified POM) to prevent gasket swelling and leakage.
Light-blocking materials (e.g., opaque or foil-lined) reduce light-induced degradation, extending shelf life.
Output range: 0.2-0.3ml per stroke for effective wetting of palms.
