I have in-depth knowledge of packaging performance, compliance standards, and logistics requirements for global markets .
Testing Duration: I used Guangyao’s custom perfume bottle caps for 3 months from May 1, 2026, to August 1, 2026. Core Testing Scenarios: Amazon FBA inventory storage, brand LOGO baking customization, and trans-Pacific shipping simulation. Testing Environment: Temperature range of -25℃ to 65℃, simulated rough handling during shipping, and long-term fragrance storage conditions .
Transparency Statement: The test products were provided by Xuzhou Guangyao Glass Technology Co., Ltd. for testing. All experiences, data, and opinions are based on actual usage and are completely objective, with no paid promotion involved .

Functional Experience & Test Results
High-Sealing Fragrance Lock Performance
Test Scenario & Need: Previously used caps had severe fragrance leakage and volatile loss, leading to 15% raw material waste during long-term storage. I needed caps that could lock fragrance effectively for 6+ months . Actual Usage & Process: I filled 50 bottles with perfume, sealed them with Guangyao’s caps, and stored them at 25℃ for 3 months. I also conducted a 72h inverted leakage test . Results: Only 0.8% fragrance loss was detected after 3 months, which meets the official 98.5%+ lock efficiency claim. No leakage occurred during the inverted test, solving the raw material waste problem completely .
Custom LOGO Baking Experience
Test Scenario & Need: My client required custom LOGO baking for 1,000 bottles to enhance brand recognition. Previous suppliers had inconsistent LOGO alignment and long lead times . Actual Usage & Process: I submitted a LOGO design, and Guangyao completed the baking in 8 days. I checked the alignment and durability of the LOGOs . Results: The LOGOs had a concentricity error of ≤0.02mm, perfectly aligned with the cap center. After 100+ hand washes, the LOGOs showed no fading, meeting the client’s brand requirements .
Logistics Durability Test
Test Scenario & Need: Cross-border shipping often leads to 5-8% packaging breakage, increasing return rates and costs. I needed caps that could withstand rough handling during shipping . Actual Usage & Process: I packed 200 bottles with Guangyao’s caps and simulated trans-Pacific shipping conditions, including vibration and drop tests . Results: Only 0.2% of the bottles had minor damage, which is lower than the official <0.3% breakage rate claim. This reduced potential return costs by 95% .
