How To Properly Fill And Seal A Deodorant Stick Bottle

Introduction: Why Correctly Filling and Sealing Deodorant Bottles Matters

For personal care brands, ensuring a professional, mess-free finish during the deodorant stick bottle filling process is essential to product quality and customer satisfaction. Whether you’re a startup or a high-volume brand, learning how to fill and seal a deodorant stick bottle the right way ensures a longer shelf life, improved user experience, and fewer returns.

At BEYAQI, a global custom deodorant bottle manufacturer, we guide our clients through the process from design to production—and that includes offering expertise on optimal filling and sealing techniques.

Step 1: Choosing the Right Deodorant Stick Bottle

Before discussing how to fill and seal deodorant packaging, selecting the right packaging format is critical. BEYAQI offers a wide variety of twist-up, push-up, and refillable deodorant stick bottles, compatible with hot-pour or solid formulas.

When choosing a model, consider:

• Filling temperature (hot or cold)

• Sealing mechanism (snap-on cap, screw cap, plug seal)

• Material compatibility with your formulation (e.g., PCR plastic, PP, or aluminum)

• User experience preferences (refillable vs. disposable)

  
  

Step 2: How to Fill a Deodorant Stick Bottle

The actual deodorant stick bottle filling process depends on your product type, but here’s a general guideline for solid or hot-pour formulas:

Hot-Pour Filling Process:

1. Melt the deodorant base to a temperature between 65°C–85°C, depending on the formula.

2. Preheat the deodorant bottles slightly to prevent shock cooling and cracking.

3. Fill the bottles from the bottom (for dual-chamber styles) or top-fill using a nozzle or dosing machine.

4. Allow the product to cool and solidify naturally or in a cooling chamber.

5. Level off the top surface using a heated spatula if needed for aesthetics.

For automated filling, BEYAQI can design bottle dimensions tailored for your machines, ensuring high-speed precision and minimal waste.

Step 3: How to Seal a Deodorant Stick Bottle

Once filled, it’s time to seal deodorant packaging effectively to protect the product during shipping, storage, and use.

Sealing Methods:

• Snap-on inner plug: Offers added protection from leaks and contamination.

• Twist-lock caps: Ideal for travel-friendly and tamper-resistant packaging.

• Heat-shrink bands: Common for added hygiene and tamper evidence.

• Foil or membrane seals (optional): Often used for natural or sensitive formulas.

At BEYAQI, we help you match the right sealing method to your product’s viscosity, temperature sensitivity, and branding goals.

Step 4: Testing for Seal Integrity

After you fill and seal a deodorant stick bottle, testing ensures that every unit meets high standards before shipping to retailers or customers.

Quality Checks Include:

• Leak tests (inverted storage or drop testing)

• Temperature durability (hot room/cold room tests)

• Twist function and glide smoothness

• Cap locking and resealing ease

BEYAQI applies rigorous QC protocols at scale to ensure consistent performance for every custom order.
