Cream and Lotion Bottling Line: How Filling, Sealing, Screw Capping, and Labeling Connect
For cream, lotion, and other paste packaging, configure filling, optional foil sealing, screw capping, and labeling equipment according to viscosity, container mouth diameter, cap
- Paste viscosity, particles, and stringing affect filling; wide-mouth bottles, pump bottles, and tubes limit downstream processes. Please provide material and container samples, cap type, whether aluminum foil liner is included, label size and position, and desired line speed.
Solution summary prepared for you
- For cream and lotion bottle lines, first judge between cream filling machine and servo piston liquid filling machine based on actual product flow, then connect capping.
- When an automatic screw capping machine handles threaded or pump head caps, complete cap samples are needed to confirm cap feeding, clamping, and tightening results.
- The inline induction foil sealing machine is only used for bottled products with a matching liner inside the cap; if this packaging structure is absent, the station is not installed.
Route comparison
- For cream-type materials that need quantitative filling into wide-mouth bottles and handling threaded or pump head caps after filling.
- A cream filling machine can be sampled around metering and discharge of viscous materials, followed by an automatic screw capping machine to form the main bottle process.
- Material viscosity, particles, fill volume, bottle neck size, and cleaning method differ; filling configuration needs to be confirmed for each type.
- If material flow does not match the cream metering method, or cap closing is not a screw tightening action, adjust the upstream and downstream processes separately.
- First test cream with a cream filling machine using actual product, then evaluate the automatic screw capping machine with production caps. Bottle neck residue and stringing are included in the two-station connection check.
- Lotion products with flow characteristics matching piston metering, and using round or square bottles for capping and labeling.
- A servo piston liquid filling machine can be a comparison direction for fluid lotions, and should be verified separately with bottle capping and labeling stations.
- Suitability is still determined by material, fill volume, filling nozzle, bottle neck, and cycle time tests, not just by the lotion name.
- If lotion has obvious stringing, particles, or special temperature conditions and actual product testing is not completed, do not finalize the configuration.
- Test the servo piston liquid filling machine with actual lotion and production bottles; after stable discharge, connect the automatic screw capping machine and round/square bottle labeling machine.
- Cream and lotion bottling processes that require cap inner sealing, bottle labeling, batch traceability, or finished product inspection.
- Cap liner induction can be inserted between capping and labeling; batch code and inspection stations are arranged further downstream according to the finished product readable surface.
- Each machine should first pass sample testing; line connection is then confirmed based on actual discharge spacing, container orientation, and available space.
- Skip the induction station when the cap has no aluminum foil liner. Do not fix downstream speed until the main bottling process is stable.
- When the cap has a matching aluminum foil liner, connect an inline induction foil sealing machine. Then use a conveying line to coordinate the round/square bottle labeling machine, date batch coding machine, and inline inspection.

Core process
First use actual cream and lotion to distinguish the suitable range of cream filling machine and servo piston liquid filling machine, and record the bottle neck cleanliness after filling.
Bottles after filling enter the automatic screw capping machine; cap feeding orientation, bottle clamping, and tightening results for threaded or pump head caps are debugged with actual parts.
When the cap has a matching aluminum foil liner, connect an inline induction foil sealing machine after capping. Skip this station for regular caps without a liner.
After the main bottle process passes with actual samples, arrange labeling and date batch coding according to bottle shape, label position, and traceability surface.
After each machine's output is stable, connect the stations with an automatic feeding conveying sealing line, and evaluate inline checkweighing and vision inspection according to finished product inspection requirements.
The proposal documents should list cream and lotion separately, and indicate caps, liners, labels, and manual steps to be retained.

Lotion flow and cream stringing can differ greatly; the machine name cannot replace actual product filling.
Pump head length and orientation affect cap feeding, clamping, and final orientation after tightening.
A regular threaded cap does not mean it has an aluminum foil liner inside; the induction station should be triggered by the packaging structure.
Fixing the conveying speed while filling and capping are still being adjusted causes downstream stations to repeatedly follow changes.
Pump head orientation, square bottle front, and label layout may have common positioning requirements.

Start Station Layout from Material Flow
Creams and lotions may both seem bottleable, but the filling station faces two potentially different flow states. First use actual product to determine whether a paste filling machine or a servo piston liquid filling machine is needed, then arrange downstream stations based on caps and labels. This is easier than drawing the whole line first.
Trial Fill Creams and Lotions Separately
Cream samples should be checked for viscosity, stringing, particles, fill volume, and residue on the bottle rim; lotions should be checked for flow, metering, and cut-off behavior. Equipment selection is determined by actual product results. If one line must handle both material types, include changeover cleaning and filling nozzle adjustment in the process.
Cream Bottles: Fill First, Then Screw Cap
After the paste filling machine passes actual product validation, filled bottles enter the automatic screw capper. For both threaded caps and pump caps, use complete cap samples to check cap feeding orientation, bottle clamping, and tightening condition, especially whether filling residue prevents the cap from seating properly.
Lotion Route Depends on Actual Material Metering
For higher-flow lotions, a servo piston liquid filling machine can be compared, but material and fill volume tests must be the basis. Only after filling is stable should capping be connected; do not treat the lotion name as a conclusion about equipment suitability.
Inner Seal Process Depends on Cap and Film Position
When the cap has an aluminum foil liner inside, an inline induction foil sealing machine is placed after screw capping. If the bottle mouth is directly covered with film, that is a different heat-sealing structure, and an inline heat sealing machine for bottles can only be evaluated after the bottle, film, and feeding method match and trial sealing passes.
Cap Orientation Must Coordinate with Label
Before labeling, determine the finished product front. The square bottle reference face, round bottle circumferential orientation, pump head direction, and label layout may constrain each other. Date and batch codes must also avoid the cap body, label seams, and hard-to-read positions.
Connect Conveying After Each Station Is Stable
The automatic feeding, conveying, and sealing line is used to connect already stable standalone machines. During commissioning, use the actual distances between filling discharge, capping completion, and labeling infeed to decide buffer, inspection, and manual sampling positions.
Put Inspection Items on the Finished Product
Inline checkweighing and vision inspection systems can be evaluated after the finished product orientation is clear. Inspection items should be written as executable weight judgments, label positions, or appearance requirements, and validated continuously with production sample bottles.
Submit Proposal Materials by Station
Prepare two types of materials, caps of each specification, liners, labels, and printing samples, along with fill volume, cleaning, target speed, and site photos. When materials are arranged by station, responsibilities for filling, closing, marking, and inspection become clearer.
Common questions
Can cream and lotion share one filling machine?
First observe the flow, stringing, particles, and end-of-fill condition using the actual product. For thick creams, evaluate a cream filling machine; for more fluid lotions, compare a servo piston liquid filling machine.
How is the screw capping action confirmed for pump head caps?
Provide bottles, caps, and filled samples to check bottle clamping, cap feeding orientation, pump head position, and the finished condition after tightening.
Do all cream bottles need induction sealing?
Only add inline induction foil sealing if the cap has a matching aluminum foil liner and the bottle material, neck, and tightening condition pass testing.
How do you gradually build a continuous bottle line from individual machines?
First stabilize filling and capping output separately, then check induction, labeling, coding, and inspection stations in sequence, and finally coordinate conveying according to the measured cycle time of each station.
Can round and square bottles be labeled on the same line?
Check the square bottle reference surface, round bottle circumferential condition, label size, and pump head orientation. Use production bottles and labels for continuous labeling observation before determining the positioning method.
What bottle information should be prepared before machine testing?
Submit each material, fill volume, bottle shape, cap type, liner, label, and batch code position, and specify changeover cleaning and planned cycle time.
