Ointment Tube from Filling and Tail Sealing to Cartoning: Tube Material, Tail Seal, and Carton Interface
Describes semi-automatic or fully automatic filling and tail sealing, tail coding, conveying, and automatic cartoning configurations for ointment tubes, clarifying the selection bo
- Empty tube feeding and pre-filled tube infeed correspond to an integrated machine or separate tail sealing; the tube material and tail coding position determine the tail sealing test. Outer carton dimensions, insertion direction, and whether a leaflet is included should be confirmed after the finished tube is stable.
Solution summary prepared for you
- Ointment tubes are first diverted by incoming material status: empty tubes require filling and sealing, while pre-filled tubes only need tail sealing and coding.
- For continuous empty tube production, use a fully automatic tube filling and sealing machine and connect a date inkjet coder. When sealed products need inner boxes, configure an automatic cartoning machine.
- Only after the inner boxes are completed do the products enter the case sealing and outer box labeling line. Before confirming the solution, you must provide samples of tubes, ointment, inner boxes, leaflets, and outer boxes.
Route comparison
- Suitable for new tube type verification, small batch production, or ointment projects where filling is already complete and only tail sealing and coding are needed.
- A semi-automatic tube filling and sealing machine can verify the combination of empty tubes and ointment, while a tube sealing and coding machine allows pre-filled incoming tubes to only handle the tail.
- Manual tube feeding and removal limit continuous operation. Tube material, diameter, and tail seal form still require molds for each specification.
- When the order already requires continuous automatic feeding, filling, and sealing of empty tubes, it is not appropriate to stay at the trial production station for a long time.
- Choose semi-automatic filling and sealing or independent tail sealing and coding according to the incoming material status. First complete sealing and batch code samples for the main tubes.
- Suitable for orders where empty tubes, ointment, and main tube diameters are confirmed and continuous filling, sealing, and batch coding are required.
- The fully automatic tube filling and sealing machine organizes empty tube feeding, dosing, positioning, and tail sealing continuously. Date inkjet coding can be integrated at a stable orientation.
- Ointment condition, tube tail cleanliness, registration marks, and multi-diameter changeover affect the actual cycle and require online material testing.
- When the incoming tubes are already filled, or the tube specifications are still changing frequently, the complete automatic filling and sealing line should not be frozen directly.
- The main line uses a fully automatic tube filling and sealing machine and is equipped with a date batch code inkjet printer according to tail or tube body traceability requirements.
- Suitable for projects where sealed products, inner box accessories, and outer box specifications are stable and continuous inner box packaging and case-level traceability are required.
- The automatic cartoning machine completes tube insertion into inner boxes, and the case sealing and outer box labeling line then handles the outer boxes of the cartoned products, making the packaging layers clear.
- Box type, leaflets, tube orientation, outer box arrangement, and cycle times of each section must be confirmed. Equipment cannot be connected by name alone.
- When the inner box or outer box is not yet frozen, or the cartoning direction is still changing, it is not appropriate to lock all downstream sections at once.
- Sealed tubes first enter the automatic cartoning machine. After the inner boxes are loaded into outer boxes in the defined manner, connect the case sealing and outer box labeling equipment.

Core process
First use empty tubes, filled tubes, and carton samples to determine tube material, diameter, tail seal form, batch code surface, and cartoning direction.
For small batches or new tube types, a semi-automatic tube filling and sealing machine can be used to verify empty tube positioning, ointment filling, and tail sealing. If the incoming tubes are pre-filled, use a tube sealing and coding machine instead.
After the main empty tubes and product are stable, the fully automatic tube filling and sealing machine continuously completes tube feeding, dosing, positioning, tail sealing, and discharge.
The date batch code inkjet printer is triggered by a stable area on the tail seal edge or tube body. The printing content and adhesion standards are determined with the project.
After the sealed tube orientation is stable, the automatic cartoning machine completes insertion into the inner box according to the inner box dimensions, tube orientation, and leaflet requirements.
Products already packed in inner boxes then enter the case sealing and outer box labeling line to complete box flap sealing and case-level identification.
Sample details
Confirm whether it is a plastic tube or aluminum-plastic composite tube, tube diameter, length, registration marks, and target tail seal form to establish the mold baseline.
Empty tubes and filled tubes, tube material markings, key dimensions, orientation marks, and tail seal samplesState whether the incoming tubes are empty or pre-filled, and use ointment samples to verify the filling cutoff and tail seal area cleanliness.
Actual ointment product, target fill weight, particles or viscosity, filling responsibility, and cleaning requirementsDetermine the batch code content, surface, and readability standards to avoid duplication between main machine coding and independent inkjet coding.
Printing position on tail or tube body, date batch code content, adhesion check, and traceability rulesProvide inner boxes, leaflets, and tube insertion direction to verify box opening, product insertion, box closing, and exception handling.

Outer box samples, inner box arrangement, case sealing consumables, case-level labels, power and air supply, and on-site spaceCommon selection mistakes
The tube material and diameter determine the positioning and tail sealing method. Only the product name cannot determine the processing conditions for plastic tubes and aluminum-plastic composite tubes.
Excessive filling depth, stringing, or tail residue can contaminate the sealing area. Even if the tail seal looks neat, there may be process risks.
When pre-filled tubes only need tail sealing, choosing a complete filling and sealing main machine creates unnecessary processes. For empty tube projects, filling cannot be omitted.
Tail seal coding, independent inkjet coding, and outer box labeling may carry different information. Without prior allocation, duplication or omission can occur.
The automatic cartoning machine and the case sealing and outer box labeling line handle different packaging layers. The former is not a case packer, and the latter does not place tubes into inner boxes.
View detailed technical notes
Incoming material status determines the first main machine
For tube packaging, first ask whether the incoming tubes are empty. Empty tubes require filling and sealing; tubes already filled with ointment only need tail sealing and coding. After the two routes are stable, discuss automatic cartoning.
Tube and Content Must Be Sampled Together
Tube material, diameter, tail cleanliness, and registration marks jointly constrain tail sealing. For ointment filling projects, also check the filling nozzle cutoff to prevent product from entering the sealing area.
Separate Filling and Tail Sealing During Trial Production
For a new tube type or small-batch orders, a semi-automatic ointment tube filling and tail sealing machine can be used. If upstream filling is already completed, a tube tail sealing and coding machine better matches the actual responsibility. Both options require tooling and batch code position to be determined with the official tube, and tail cleanliness, positioning marks, and trim appearance must be verified.
Use Continuous Filling and Sealing for Stable Orders
Once the main empty tube, ointment, and fill volume are stable, a fully automatic ointment tube filling and tail sealing machine continuously performs tube feeding, dosing, positioning, and tail sealing, with date coding integrated according to the traceability surface. Continuous trial runs must also record tube tail residue, orientation detection, abnormal stop recovery, and changeover cleaning.
Cartoning and Case Sealing Are Two Downstream Layers
Before sealed tubes enter the automatic cartoning machine, the tube body orientation, inner carton direction, and inserts such as leaflets must be determined. After the inner carton is completed, outer case sealing and labeling belong to the next packaging layer. The infeed, outfeed, and cycle time of the two equipment sections must be verified separately; cartoning and case sealing cannot be merged into one vague downstream stage.
Tail Seal Acceptance Is Not Only Visual
Tail seal pattern, trim, and batch code appearance alone cannot prove seal integrity; acceptance must also consider tube tail cleanliness, content compatibility, and the methods specified in the project.
Plan Changeover Costs in Advance for Multiple Specifications
Changes in tube diameter or material affect tooling, positioning, tail sealing, and coding. Common specifications and changeover responsibility should be itemized in the quotation.
Complete Line Documentation Must Cover Every Packaging Layer
Only when the tube, ointment, inner carton, leaflet, outer case, and traceability artwork are available simultaneously can the real interface from filling and tail sealing to shipping packaging be verified.
Keep Acceptance Boundaries Before Sample Approval
If samples or carton styles are not yet frozen, only confirm the equipment branches and interfaces; sealing, cartoning, and continuous cycle time remain as verification items.
Common questions
How is the configuration of an ointment tube filling and sealing line determined?
The configuration depends on whether the incoming tubes are empty or pre-filled, the tube material and diameter, the tail sealing and batch coding method, whether automatic cartoning is required, the outer box specifications, and the continuous cycle time. It must be confirmed with a complete set of samples.
Can one set of tube equipment handle multiple tube diameters?
It is possible to change molds for production within a verified range, but the tube material, diameter, registration marks, and tail seal width will change the tooling and sealing conditions. Each main specification must be sampled and tested.
How to handle batch codes on tubes that are easily rubbed off?
First confirm whether the batch code is printed on the tail seal or the tube body, then test ink or ribbon adhesion with the actual tubes. Include rub resistance, readability, and storage/transport conditions in the acceptance criteria.
Can sealed tubes be continuously cartoned and case sealed?
Yes. After the fully automatic filling and sealing machine stabilizes the tube orientation, the automatic cartoning machine handles the inner boxes, and the cartoned products then enter the case sealing and outer box labeling station.
What should be checked first when ointment leakage appears in the tail seal area?
First check whether the ointment enters the tail seal contact area, then verify the filling cutoff, tail cleaning, tube material, and sealing conditions. Do not simply increase temperature or pressure.
Is a complete integrated line necessary for small batches of ointment?
No. You can first use a semi-automatic filling and sealing machine or a tube sealing and coding machine to verify the main tubes. The inner box and outer box downstream sections can be expanded later according to the interface once orders are stable.
