Fully automated dosing and internal hot-air sealing system for plastic and co-extruded tubes. Includes automatic tube feeding, photoelectric registration, and clean edge trimming.
Versatile Industrial Tube Filling & Sealing Solutions
EAC Machinery Co., Ltd. engineers and manufactures high-performance automatic tube filling and sealing machines designed for plastic (PE, PP), laminated (ABL, PBL), and metal/aluminum tubes. Capable of continuous speeds up to 80-120 tubes per minute, our equipment accurately doses viscous creams, gels, toothpaste, ointments, adhesives, and food pastes.
Equipped with advanced Mitsubishi PLC touchscreen controls, servo-driven dosing pumps, and hot-air or ultrasonic tail-sealing mechanisms, our tube sealers maintain rigorous GMP compliance. Each machine features dust-proof organic glass enclosure, automatic tube registration via photoelectric orientation sensors, and precise anti-drip filling nozzles.
Whether you require a semi-automatic desktop unit for laboratory R&D or a fully automated multi-lane production system integrated with downstream cartoning, EAC Machinery Co., Ltd. provides turn-key customization to match your target output.
Tube Filling and Sealing Machine Series
Select from our specialized line of tube packaging equipment optimized for your specific container materials, filling volume, and automated manufacturing requirements.
Aluminum Tube Filling and Sealing Machine
Designed specifically for metal and aluminum soft tubes. Features mechanical multi-fold mechanical crimping (saddle fold, double fold) and clear date/batch code embossing.
Ultrasonic Tube Sealing Machine
Employs high-frequency ultrasonic energy to seal tube ends through product contamination or oily residue. Produces aesthetic, hermetic seals without thermal degradation of sensitive formulas.
Semi-Automatic Tube Filling & Sealer
Compact, economical choice ideal for pilot batches, labs, or small cosmetic facilities. Manual tube feeding combined with precise automated filling and tail sealing (30–35 tubes/min).
High-Speed Automatic Tube Line
Dual-nozzle rotary indexer achieving up to 110 tubes/min. Complete with vacuum tube feeding, jacketed heated hopper with agitator, and auto discharge to cartoning conveyors.
Toothpaste & Ointment Tube Filler
Engineered for highly viscous pharmaceutical creams and multi-color gel toothpastes. Features blow-back anti-stringing nozzles and no-tube-no-fill optical sensors.
Key Engineering Advantages
Why global pharmaceutical, cosmetic, and food brands trust EAC Machinery Co., Ltd. for their tube packaging operations.
User-Friendly HMI
Intuitive Mitsubishi touchscreen interface with real-time diagnostic graphics, parameter storage recipes, and electronic output counter.
Rapid Changeovers
Modular tube holder pucks and toolless dosing adjustments allow seamless switching between different tube diameters and formulas.
High Dosing Accuracy
Rotary valve piston pumps and servo actuators ensure high volumetric filling precision (< ±1%) while eliminating product dripping or tailing.
Sanitary GMP Construction
Fabricated with AISI 316L stainless steel contact points, sanitary quick-release tri-clamp fittings, and transparent safety interlocks.
Working Principle & Process Sequence
Our automatic tube filling and sealing machine integrates mechanical indexing drive systems with precise pneumatic and electronic controls for consistent performance:
-
Automatic Tube Loading: Slanted tube storage hopper automatically loads tubes into index cup holders using vacuum suction.
Photoelectric Orientation: High-precision color mark sensors rotate tubes 360° to ensure exact front-and-back logo registration.
Internal Air Cleaning & Vacuum: Pressurized air jet blows clean air into tubes while vacuum removes dust particles before filling.
Precision Volumetric Dosing: Anti-drip diving nozzle enters tube base, filling from bottom up to avoid air trap and bubbles.
Heating & Sealing: Internal hot air nozzles heat the inner wall of tube tail, followed by pneumatic water-cooled sealing jaws pressing the seal.
Code Embossing & Trimming: Batch codes/dates are embossed into tail seal while custom profile knives trim excess waste edge (R-angle or straight).
Ejection & Conveyance: Finished sealed tubes are automatically discharged onto outfeed conveyor leading to cartoning machinery.

Frequently Asked Questions
Technical details and purchasing inquiries regarding EAC Machinery Co., Ltd. tube filling systems.
What tube materials can your tube filling and sealing machine handle?
Our machines are engineered to process plastic tubes (PE, PP), aluminum-barrier laminated tubes (ABL), plastic-barrier laminated tubes (PBL), and pure metal aluminum soft tubes using appropriate hot-air, ultrasonic, or mechanical crimping toolings.
What is the difference between Hot-Air Sealing and Ultrasonic Tube Sealing?
Hot-Air sealing uses heated air directed inside plastic tube tails to melt the material before clamping. Ultrasonic sealing uses high-frequency vibrations to bond plastic layers without thermal residual heat, which is superior when handling heat-sensitive cosmetics or formulas containing oils.
How do I change tube cup holders when switching tube diameters?
Our rotary turntables feature quick-release puck mounts. Operator changeovers between different tube diameters usually take less than 15 to 20 minutes with zero complex alignment required.
What after-sales service and spare parts support do you provide?
EAC Machinery Co., Ltd. provides a 2-year warranty on all machines. We ship critical wear parts via international express and provide 24/7 video guidance, electrical diagrams, and optional overseas technician on-site installation.
