Orifice Reducers & Sifters
Precise control over every drop. Available in multiple orifice sizes to ensure even dispensing of liquid serums or loose powders, preventing product waste. Engineered with micron-level tolerances to guarantee a seamless, secure fit within the bottle neck.
Tamper Evident Closures
The first line of defense in building consumer trust. The security ring breaks automatically upon the first opening, providing clear visual and auditory feedback. Ensures your products remain secure and uncontaminated on retail shelves and during e-commerce transit.
The Science of a Perfect Seal
Caps are the most vulnerable component in cosmetic packaging. Fomalhaut strictly follows global GPI/SPI thread standards and provides customized liner solutions to ensure your formula remains completely leak-proof.
Demystifying Neck Finishes
Finding the perfect match starts with understanding the numbers. Take the common standard 24/410, for example: "24" indicates the outer diameter of the bottle neck is 24mm, while "410" refers to the specific thread style, determining the number of turns and height.
We manufacture and supply a comprehensive range of cosmetic caps covering all standard GPI/SPI neck finishes, from 18/410 to 28/410. This ensures a precise, secure fit with your existing standard bottle measurement and thread profiles.
Advanced Liner & Plug Technology
While the cap secures the closure, the liner creates the actual seal. Different cosmetic formulas require specific chemical compatibility to prevent degradation. We provide engineered cosmetic cap liners for every application:
-
PE Foam Liners
Ideal for most standard lotions and creams, offering excellent physical cushioning and leak-proof performance.
-
Induction Seal Liners
Provides an airtight, tamper-evident barrier that significantly extends product shelf life.
-
PTFE/Teflon Liners
Specifically engineered for highly aggressive formulations, such as pure essential oils and acid-based skincare.

Zero Tolerance for Leakage
A failed closure means a ruined formula. Fomalhaut applies rigorous testing beyond industry standards to ensure your products remain strictly leak-proof from the filling line to the consumer's hands.
Torque & Thread Stripping Test
Caps can be damaged on automated filling lines, or consumers may find them difficult to properly tighten or open.
We utilize high-precision torque testers to measure the application and removal torque peaks. This ensures the closures perfectly adapt to your high-speed automated filling lines while providing a smooth, non-stripping opening experience for consumers.
Focus Areas: Cap torque testing, Thread stripping test, Cosmetic closure quality control
Vacuum Leak Testing
Products frequently leak during international air freight due to pressure changes or rough handling in e-commerce transit.
Every batch of closure and bottle combinations undergoes a continuous 10-minute water immersion test in a -0.06 MPa high-vacuum negative pressure chamber. We simulate extreme aviation transit pressure and inverted states to guarantee your liquid serums and highly active formulas never leak.
Focus Areas: Vacuum leak testing for bottles, Leak-proof cosmetic caps, Air-tight closures
Hinge Fatigue Test
Disc caps or flip top caps often break at the hinge connection after repeated consumer use.
For disc and flip top caps, we conduct over 1,000 continuous mechanical opening and closing fatigue tests. By optimizing the toughness of the PP material and the mold structure, we ensure the hinge remains intact and secure throughout the product's entire lifecycle.
Focus Areas: Flip top cap hinge test, Disc cap durability, Closure fatigue testing
Liner Compatibility & Sealing Test
While the cap exterior remains intact, the internal liner can be corroded by aggressive formulas like essential oils, leading to leakage.
Closure sealing relies heavily on the internal liner. In high-temperature and high-humidity environments, we test the chemical compatibility of various liners (such as PE foam, aluminum foil, and Teflon) with your specific bulk formula. This prevents liner swelling, deformation, or loss of elasticity.
Focus Areas: Cosmetic cap liners, Liner compatibility test, Essential oil cap sealing
Crown Your Brand with Custom Finishes
Elevate standard closures to bespoke quality without expensive custom molds. Fomalhaut's comprehensive surface finishing technologies ensure your cosmetic caps perfectly align with your brand's visual identity.
Custom Pantone Injection
Achieve exact color consistency for your packaging. We provide precise Pantone color matching during the plastic injection process. With a minimum order quantity of 5,000 pieces, you can ensure your cosmetic caps seamlessly align with your primary brand colors or existing containers.
Top Embossing & Debossing
Integrate your brand logo directly into the packaging structure. We manufacture precise 3D embossed (raised) and debossed (recessed) details on the top of metal and thick-wall plastic caps. This method offers a durable and tactile branding solution for premium skincare jars and perfume closures.
Vacuum Metallization
Attain a premium metallic finish on lightweight plastic components. Our vacuum metallization process applies high-gloss gold, silver, or custom metallic tones, as well as matte brushed effects, to standard ABS or PP caps, enhancing the visual appeal of your cosmetic packaging.
Water Transfer & Soft-Touch
Apply specialized textures and patterns to standard closures. Through water transfer printing, we can replicate realistic wood grain or marble finishes on plastic caps. Adding a soft-touch coating provides a matte appearance and a smooth, velvet-like tactile experience for consumers.
Frequently Asked Questions
about Cosmetic Caps
Clear answers for your sealing challenges. No hidden terms, just transparent manufacturing.
I already have my own bottles. How can you ensure your caps will fit perfectly and not leak?
This is the most common challenge in cosmetic packaging when sourcing from multiple suppliers. We strongly recommend sending your existing bottle samples to our facility. Our engineering team will conduct complimentary torque testing for bottles and -0.06 MPa vacuum negative pressure leak tests. Only after our laboratory confirms a 100% perfect fit and zero leakage will we recommend the most suitable leak-proof closure matching solution, ensuring your cosmetic cap compatibility test is fully documented and reliable.
What is the minimum order quantity (MOQ) for custom Pantone colored plastic caps?
We understand the importance of a unified brand visual identity. Unlike the industry standard that often requires tens of thousands of units, Fomalhaut supports precise Pantone matched cosmetic closures with an MOQ as low as 5,000 pieces. Whether you need flip-top caps, screw caps, or tamper-evident closures, we help you achieve a premium custom look with low MOQ custom colored caps and small batch plastic lids, significantly minimizing your inventory risk.
Which caps and liners should I choose for formulas with high concentrations of essential oils or acids?
Highly active formulations can easily degrade standard packaging materials. For essential oils and acidic skincare products, we recommend highly chemical resistant closures such as PETG or aluminum screw caps. More importantly, the internal seal is critical: you must replace standard PE foam liners with specialized PTFE liners for cosmetics or aluminum foil seals with anti-corrosion coatings. Our technical team will analyze your specific formula to provide professional material recommendations, ensuring your essential oil bottle caps remain secure and intact over time.
Do your child-resistant closures (CRC) comply with international safety standards?
Absolutely. Our child-resistant closures feature a reliable push-and-turn mechanism that has been strictly tested and verified. As a professional CRC packaging manufacturer, we ensure our products are fully ISO 8317 certified caps and CPSC compliant child resistant closures. We provide complete compliance testing reports with your bulk orders, guaranteeing that your pharmaceutical-grade skincare or CBD products can smoothly enter and be sold in global retail markets.
