🛠️ What Is a Rotary Tube Filling and Sealing Machine?
A rotary tube filling and sealing machine is an industrial packaging machine used to automate the process of filling and sealing “tubes” — such as those made of plastic, aluminum, or laminated materials — with creams, gels, pastes, ointments, and other semi-viscous products. These machines are widely used in pharmaceuticals, cosmetics, food products, and chemical industries.
🔄 “Rotary” Means Continuous Production
The term “rotary” refers to how the machine’s internal components are arranged on a rotating table or turret. As this table turns, tubes move through a series of stations that each perform a step in the process — such as filling, sealing, trimming, and ejecting the finished tube — making it ideal for medium to high-volume production
How It Works: Step by Step
Here’s the typical workflow of a rotary tube filling and sealing machine:
Tube Loading
Empty tubes are placed — automatically or manually — into holders on a rotating turret.
Indexing & Positioning
The rotating system moves tubes precisely beneath the filling head in a timed sequence
Filling
Each tube is filled with a measured quantity of product (cream, gel, paste, etc.) via a dosing pump or volumetric filler
Sealing
Tubes are sealed — often with heat (hot air) or crimping — to close the filled tube end securely, sometimes with
batch code or date printing. Trimming & Coding
Excess material is trimmed and codes (like lot number, expiry) can be embossed.
Typical Applications
These machines are used to package products like:
· Pharmaceuticals — ointments, medicinal gels
· Cosmetics — lotions, creams, gels
· Food products — sauces, pastes
· Chemicals — adhesives, sealants
· Personal care — toothpaste, shampoo in tube format
