Müşteri Arka Plan
A top UK skincare manufacturer was looking for a dropper bottle factory that could provide them with high quality packaging for their facial serum range. The company was looking to elegant packaging that was not only leak-proof but would be suitable for both the online channel and retail distribution.
The client ordered 50ml frosted amber damlalıklı şişeler featuring a thick glass bottom and a shiny black rubber bulb along with an aluminum collar. Designed for essential oils and active skin care serums that demand accurate dispensing and superior sealing performance. Our experience in cosmetic glass packs, neck finish manufacturing and quality export helped us be chosen by the brand for their work.
Meydan okumak
Serum Leakage During Transportation
After shipment, some bottles showed liquid seepage around the neck area, especially after long-distance transport and temperature changes.
Inconsistent Dropper Tightness
During assembly, certain droppers were either too loose or excessively tight, affecting filling efficiency and user experience.
Neden Analizi
Our technical and QC teams conducted detailed testing and found two major causes:
- Slight dimensional inconsistencies between the bottle neck and dropper cap created uneven sealing pressure.
- The gasket material inside the dropper assembly lacked sufficient resistance to oil-based serum formulas.
Çözüm
Precision Neck Finish Optimization
As an experienced dropper bottle factory, we recalibrated neck molds and tightened tolerance control to improve compatibility between bottles and droppers.
Upgraded Sealing Components
We replaced the standard gasket with a more chemical-resistant liner material designed specifically for essential oil and serum applications.
Leakage & Transport Testing
Tilt tests, vacuum tests, and vibration simulations were performed to verify sealing performance under real shipping conditions.
Sonuç
Leakage complaints were significantly reduced, and the client achieved smoother automated filling and assembly processes. Product appearance and customer satisfaction improved across both online and retail channels.
By partnering with Minghanggroup as their long-term dropper bottle factory, the UK skincare brand secured reliable cosmetic packaging with stable sealing and premium presentation.
