How to Choose Sealing and Labeling for Cat Food Cans? Start With Can Type and Label
Pet canned food packaging is not only about the sealing machine. First confirm whether the can is metal or plastic, the can-mouth structure, film or foil liner, cap type, label position, and target output, then decide the sealing, capping, and labeling route.

- How to Choose Sealing, Cap Pressing and Labeling for Pet Food Cans
First Break the Requirement Into Key Points
I want to package pet food cans with sealing, cap pressing, and labeling. How should I choose equipment?
First determine the packaging route
Pet canned food packaging is not only about the sealing machine. First confirm whether the can is metal or plastic, the can-mouth structure, film or foil liner, cap type, label position, and target output, then decide the sealing, capping, and labeling route.
Metal Can Seaming Route
Suitable for: Double seam sealing of round metal cans, common for wet pet food cans. Advantages: High seam strength, suitable for long-term storage and high-temperature sterilization. Limitations: Can lid and body must match; seaming rolls and base plate need customization per can diameter. Not recommended: For plastic or paper containers, double seaming is not applicable; consider heat sealing or induction sealing. Equipment direction: We offer can seamers with seaming rolls and base plates configured per can diameter, supporting standalone or inline production.
Plastic Jars / Paper-can Aluminum Foil Film Sealing + Cap Pressing Route
Suitable for: plastic jars or paper cans, first heat seal aluminum foil membrane, then press outer cap. Advantages: foil seal effect needs sample confirmation; capped appearance neat, suitable for pet treat cans. Limitations: can mouth flatness and film compatibility affect sealing; sample testing required. Not recommended: if cap is screw type, pressing cannot meet torque requirements; consider screw capping route. Equipment direction: we can provide paper can/plastic pail foil sealing and capping machine; confirm mold per can, film, and cap samples.
Capping Route (Plastic Jars / Glass Jars)
Suitable for: Threaded plastic jars or glass jars, sealed by screw capping. Advantages: Torque controllable, suitable for pet food cans needing repeated opening. Limitations: Cap threads must match jar threads; torque must be tested per sealing requirements. Not recommended: If the lid is a press-on or snap-on type, screw capping cannot be used; consider press capping. Equipment direction: We can provide automatic screw capper or combination screw/press capper, with capping heads configured per cap type and diameter.
Recommended Equipment Route: Sealing / Can Seaming
Choose by can body material: metal cans use a can seamer, while plastic or paper cans use a foil film sealing and capping machine for heat sealing.
Recommended Equipment Route: Cap Pressing or Capping
After sealing, choose press capping or screw capping according to cap type, and confirm both seal quality and appearance.
Recommended equipment route: Labeling
Label on the can body; confirm can shape, label size, and label position.
Recommended equipment route: Coding (optional)
Print production date, batch number, or traceability code, usually before or after labeling.
Route comparison
- Suitable for double seaming round metal cans, commonly used for wet pet food cans.
- Double seaming provides high sealing strength and is suitable for long shelf life or high-temperature sterilization.
- Can lid and can body must match; seaming rollers and can lifter plates are customized by can diameter.
- If the container is a plastic can or paper can, double seaming is not suitable. A heat-sealing or induction-sealing route is usually recommended instead.
- We can provide a can seaming machine, configured with seaming rollers and can supports according to can diameter, for stand-alone or connected production.
- Suitable for plastic cans or paper cans: first heat-seal aluminum foil film, then press the outer cap.
- Foil sealing should be confirmed with samples. After lid pressing, the can looks clean and is suitable for pet snack cans.
- Can rim flatness and film compatibility affect sealing results, so sample testing is required.
- If the lid is a screw cap, pressing cannot meet torque requirements, so a screw-capping route is recommended.
- We can provide a paper can or plastic pail foil sealing and lid pressing machine, with tooling confirmed from can, film, and lid samples.
- Suitable for threaded plastic or glass jars, sealed by screw capping.
- Controllable capping torque suits pet food cans that need repeated opening.
- Cap thread and can-mouth thread must match, and torque should be tested according to sealing requirements.
- If the can lid is a press cap or snap-fit cap, capping cannot be used and a cap-pressing route is recommended.
- We can provide an automatic capping machine or a capping and pressing integrated machine, with heads configured by cap type and diameter.

Sample details
Photos and dimensions can first determine container positioning, mold direction, and whether sample testing is needed.
Please provide can samples or photos, including can material, mouth diameter, and height, so the sealing method can be judged.Film material and liner affect sealing temperature, pressure, dwell time, and feeding method.
Please provide sealing film or aluminum foil liner samples to test sealing temperature and pressure parameters.The lid structure determines the capping method (press, screw, or place) and whether inline integration is needed.
Please provide cap samples, including cap type (screw cap/press-on cap/snap cap) and dimensions, for matching capping or pressing molds.Capacity target determines single machine, semi-automatic, or continuous inline configuration, and also affects the quotation range.
Please tell us the target output, such as cans per hour or per day, to determine equipment speed and line configuration.Site conditions affect electrical control, pneumatics, conveyor length, and safety protection configuration.
Please specify whether inline production is needed (e.g., filling, coding, checkweighing, case packing) and the on-site space dimensions. If information is incomplete, you can first send existing photos and dimensions...Common selection mistakes
Common questions
Yes. Send photos of the can, approximate dimensions, cap samples, and target output. We can first determine the sealing and labeling route, then list the additional information needed.
We need can samples or dimensions, sealing membrane or gasket samples, cap samples, target output, whether line integration is needed, and site space. If information is incomplete, you can still send what you have.
Output determines equipment speed and inline method. Low speed allows manual or semi-automatic; high speed requires fully automatic inline, also affecting conveyor, cap feeder, and labeling configuration.
Sealing performance depends on the bonding temperature, pressure, and time between the film and container mouth. Different films require different parameters; testing is needed to determine suitable sealing conditions.
Sealing effect needs to be confirmed through sample testing, including seal strength, leak test, and visual inspection. Film, parameters, and can rim match all affect results.
If there is filling upstream and labeling, coding, or cartoning downstream with high capacity, inline integration is recommended. Standalone machines suit small batches or samples; inline is for continuous production.
