Route comparison
- Plastic cans with a flat rim use aluminum foil film or composite film matching the can material for direct heat sealing, then install the outer lid and label after sealing.
- Powder filling, bottle online heat sealing, and can body labeling can be arranged in clear steps, making it easy to trial fill, seal, and label separately.
- Powder residue, rim flatness, film heat-seal layer, support method, and multi-diameter mold change all require physical verification.
- When the lid already has an induction aluminum foil liner and the packaging relies on screw capping to press it, the process should be changed to induction instead of direct film lidding.
- The powder granule filling machine completes metering, the bottle online heat sealing machine handles direct film lidding, and the round bottle square bottle labeling machine is configured according to the can body and label samples.
- Composite paper cans with a stable heat-sealable rim use aluminum foil film for inner sealing and press-fit plastic or metal outer lids after sealing.
- The paper can/plastic pail aluminum foil film sealing and press capping machine can connect film sealing and outer lid pressing in the same equipment process.
- Paper can rigidity, rim flatness, film heat-seal layer, lid stress, and label application condition must be verified with samples.
- If the paper can rim is deformed or cannot be stably supported, the container structure should be addressed first, and sealing and press capping tooling should not be made directly.
- The powder granule filling machine works with the paper can/plastic pail aluminum foil film sealing and press capping machine, and labeling equipment is connected after the finished can posture is confirmed.
- Plastic cans with screw caps, where the aluminum foil liner matches the can mouth material and fits the rim after tightening.
- The benchtop air-cooled induction foil sealing machine can handle liner inner sealing after screw capping and can be integrated into a small conveying process according to project conditions.
- Can material, diameter, liner structure, lid tightening state, passing posture, and operating intensity all require sample confirmation.
- When the can mouth uses roll film direct heat sealing, or the cap has no matching aluminum foil liner, return to the heat sealing process.
- After powder filling, complete the lid installation first, then use the benchtop air-cooled induction foil sealing machine to trial the liner inner sealing, and arrange the labeling station afterward.

Core process
Measure the can mouth and body, observe powder flow and dust, and distinguish direct film lidding, lid liner, and outer lid structure.
The metering and discharge method of the powder granule filling machine must be confirmed based on powder flow, caking, dust, target fill volume, and cleaning requirements.
Use heat sealing when directly placing film on the plastic can mouth; use induction when the screw cap has a matching aluminum foil liner and the lid closure is stable.
After direct film sealing of paper cans, the outer lid can be pressed; before induction sealing of plastic can lid liners, the lid must be screwed tight; the actions are evaluated separately by lid type.
After the can diameter, label size, application position, and printing content are clear, verify positioning, triggering, and conveying posture.
Photos are used to identify the can-film-lid structure, powder description is used to troubleshoot metering difficulties, and finished proofs are used to determine sealing and labeling positions.
Sample details
Container information is used to verify filling positioning, sealing support, lid action, and labeling method, and to determine whether custom molds are needed.
Provide physical plastic or paper cans, and specify the diameter, height, rim width, and can body labeling area.Powder trials are used to compare metering and discharge methods, while observing residual powder at the can mouth and changeover cleaning conditions.
Submit the planned seasoning powder and describe flow, caking, particles, dust, fill volume, and cleaning requirements.The packaging structure is used to distinguish heat sealing and induction; complete trial sealing also verifies the heat-seal layer, lid closure, and can mouth cleanliness.
Provide direct heat-seal film, or provide an induction aluminum foil liner installed in the lid and the matching lid.The lid type determines pressing, screwing, and positioning actions, and also changes the process sequence before or after the sealing equipment.
Submit physical press caps or screw caps, and specify the lid incoming direction and manual or automatic lidding requirements.This information is used to arrange stations, buffers, changeover, and cleaning, avoiding checking only the main machine while ignoring the entire flow.
List common can types, batch quantity, target production pace, and whether filling, sealing, and labeling are continuous.First divide the filling and sealing direction based on structure, then complete the samples needed for trial filling, sealing, and labeling.
If physical samples are not yet complete, you can first submit photos, dimensions, powder description, lid film structure, and finished label proofs.Common selection mistakes
Use actual powder to observe feeding, metering, powder drop, and cleaning, then confirm the configuration of the powder granule filling machine.
Combine the can, film, and lid into a sample set, and verify the boundaries of direct heat sealing and screw cap liner induction separately.
Mark the sequence of lidding, sealing, and lid closure in the flow chart, then verify the lid supply and positioning method.
First verify filling and can mouth cleanliness with actual powder, then arrange conveying spacing and buffer according to process time.
Use finished sample cans and label proofs for trial labeling, and mark the printing area and required downstream interface in advance.

First Break Down the Three Conditions: Powder, Can Type, and Lid Film
Seasoning powder can filling is not simply placing filling, sealing, and labeling equipment together. First confirm metering and powder drop with the actual powder, then divide the sealing process according to plastic or paper cans, direct film or lid liner.
Powder Trial Filling Determines the Upstream Process
The flow, caking, granules, and dust of seasoning powder affect feeding, metering, filling drop point, and cleaning. Powder granule filling machines should be tested with the actual material, and residual powder on the can rim should be observed.
Plastic Cans with Direct Film Use Heat Sealing
When aluminum foil film or composite film is placed directly on the can mouth, an inline bottle heat sealing machine can handle it. Can material, rim, film heat-seal layer, and support method must be trial-sealed as a set, and the outer cap action is confirmed afterward.
Paper Cans: Seal Film First, Then Press Outer Cap
Composite paper cans can use a paper can/plastic pail aluminum foil sealing and press capping machine to complete film sealing and outer cap pressing. Paper can rigidity, rim flatness, film heat-seal layer, and cap force must be verified together with filled cans, official film, and cap samples.
Lid Liners Use Induction Sealing
When a plastic can screw cap has a matching aluminum foil liner, first verify cap tightening, then test inner sealing with a benchtop air-cooled induction foil sealing machine. Direct-film cans without a liner do not use this structure.
Complete Samples Run Through from Filling to Labeling
Cans, powder, sealing film or liner, cap, and label should be numbered as a set by specification. Trial filling, trial sealing, cap closing, and trial labeling records together determine tooling and process sequence.
Powder Filling First Solves Powder Drop and Cleaning
The metering method, feeding, and filling nozzle of the powder granule filling machine should be determined based on the actual seasoning powder. Record powder performance during dropping, rim residue, and cleaning during material change.
Heat Sealing or Induction Depends on Packaging Structure
Plastic cans with direct film use an inline bottle heat sealing machine; screw caps with liners are evaluated for induction equipment. Both inner sealing processes must be based on complete can-film-cap trials.
Press Capping and Screw Capping Are Handled Separately by Cap Type
After film sealing, the outer cap of paper cans can use a pressing action; induction liners require screw capping to press the liner against the rim. Cap feeding, positioning, and automation scope are confirmed with actual cap samples.
Labeling and Coding Are Placed After the Finished Product Posture Is Stable
Round/square bottle labeling machines are configured according to can diameter, label size, and application position. If date/batch coding has clear traceability requirements, combine conveying posture to arrange triggering and installation area.
Common questions
Can we divide the equipment process steps with only photos of the cans and powder?
Photos can first help identify the can type, lid film structure, and powder condition. To determine the metering, heat sealing or induction sealing, and labeling tooling, a complete set of physical samples is still needed.
What samples should the solution materials include?
Please prepare plastic or paper cans, actual powder, sealing film or liner, lid components, and labels, and specify fill volume, cleaning requirements, production pace, changeover, and site conditions.
Which station arrangements does the production pace involve?
It involves the filling station, can supply method, sealing waiting, outer lid action, buffer conveying, and labeling connection, and must be judged together with powder discharge stability.
Why should the sealing material be tested together with the can mouth?
The heat-seal layer of the film or the induction liner must match the can mouth material and the lid closure structure. Complete trials are needed to observe changes caused by sealing, can body stress, and powder contamination.
How should seasoned powder cans be inspected after sealing?
Check the film surface, sealing area, lid position, and leakage signs according to the agreed method, and determine retention samples and handling inspection based on the powder moisture requirements.
Under what circumstances should single machines be expanded into a line?
When powder filling, sealing, lidding, and labeling are stable, and the stations need continuous flow and the site allows buffer setting, then evaluate the conveying and control connection.
