Pre-Filling vs. Post-Filling: Choosing the Right Filling Method for Cosmetic Tubes
When purchasing cosmetic packaging tubes, one critical decision is how the product will be filled. There are two common approaches: pre-filling (before sealing) and post-filling (after tube production but before sealing). Each method has its ideal use case and equipment requirements.
1. Pre-Filling (Before Tube Sealing)
In this method, the soft tube is filled before the tail end is sealed. This is the most common practice in professional tube production lines.
Best for:
-
Medium to large-scale production
-
Brands with access to automated or semi-automated sealing equipment
Advantages:
-
Faster and more efficient for bulk quantities
-
Sealing and filling are integrated in the same production flow
-
Suitable for high-viscosity and heat-sensitive products
Considerations:
-
Requires a tail-sealing machine
-
Tube must remain upright after filling to prevent leakage before sealing
2. Post-Filling (Filling from the Nozzle End)
Also called top filling, this method involves filling the tube after the bottom has already been sealed. It’s often done manually or with a simple filling tool.
Best for:
-
Small-batch orders
-
Handmade or artisanal beauty products
-
Startups and labs without full-scale equipment
Advantages:
-
No sealing machine required
-
Ideal for sampling, testing, or low MOQ runs
-
Flexibility in filling multiple types of products in small volumes
Considerations:
-
Typically requires a special cap or applicator
-
Can be less efficient and slower for large orders
Conclusion
Choosing between pre-filling and post-filling comes down to your production setup, batch size, and whether you have sealing capabilities in-house. For startups, post-filling is a flexible entry point, while established brands generally opt for pre-filling to ensure consistency and speed.
