Negative Pressure Vacuum Tin Can Sealing Machine
Negative-Pressure Seaming for Round Metal Cans
Use this equipment brief to review a filled metal can, its matching end and the proposed vacuum seaming cycle. Start with the package geometry and product behavior, then agree the vacuum conditions and seam inspection required for your application.

Reference Specifications
The following information describes the Levapack reference model. It is not a confirmed Deepack equipment specification.
| Item | Reference description |
|---|---|
| Source model | LPE-NPS35 |
| Source sealing rate | 20–40 cans/min; reference claim, not a confirmed Deepack output |
| Source container examples | Round tin and aluminium cans |
| Source product examples | Canned meat, beans, fish and liquid products |
| Source process context | Seaming before a downstream retort process |
| Dimensions, power and vacuum level | Not provided in the reviewed description; request offered-machine data |
| Deepack offer | Model, output, tooling, utilities and acceptance criteria require confirmation |
Source and confirmation limits
The reviewed description does not specify can dimensions, electrical supply, pump capacity, vacuum setpoint or measured oxygen results. Request documents and a sample demonstration for the actual offer.
Review the Can, Vacuum Cycle and Seam
Match the can body and end
Supply flange, end and body drawings with actual filled samples. Check chuck and roller profiles, can support and format-change parts for each size. Include the container supplier in the seam acceptance review.
Define the evacuation conditions
Specify fill temperature, headspace and product consistency. Ask the supplier to demonstrate the evacuation and pressure-release sequence while checking for product carryover, foaming and container deformation. Confirm pump, connections, cleaning provisions and included equipment.
Inspect the completed seam
Agree inspection methods, sampling and limits for the chosen can and end. Record results during the sample run and after any required downstream process. Vacuum settings alone do not establish seam quality.
Coordinate the Downstream Retort Process
The reference positions this machine for cans that enter a retort after seaming. The seamer does not establish a thermal process or certify the finished food package.
Review the filled container, seam and subsequent processing conditions with the relevant equipment and process specialists. Agree handling between the seamer and retort, batch identification and package checks after processing. No sterilization schedule or shelf-life claim is specified here.
Compare the Separate Vacuum Equipment Routes
This negative-pressure tin-can route is distinct from the vacuum-and-nitrogen equipment below. Nitrogen hardware, gas consumption, operating sequence and performance must be checked separately; their specifications do not transfer to this model.
Prepare a Representative Sample Trial
- Provide the intended can and end, product, fill quantity and temperature.
- Demonstrate loading, end handling, evacuation, seaming and release on the proposed equipment.
- Measure actual sustained output with the agreed package and cycle.
- Record seam results, package condition and separately agreed vacuum measurements.
- Review the package after its intended downstream process with the responsible specialists.
Define each measurement method before the trial. Residual oxygen, vacuum retention and preservation performance are not inferred from the product name.
Review the Trial RequirementsNegative-Pressure Can Seaming FAQs
Is this a nitrogen flushing machine?
This page concerns the negative-pressure source model. Nitrogen supply and flushing are not established by its reviewed description. Use the separate nitrogen-model pages for those equipment routes.
Is 20–40 cans/min a Deepack guarantee?
No. It is a reference-source rate. Confirm the offered machine output using the intended container, product and complete cycle.
Which can sizes can be sealed?
The reviewed description gives no dimensional range. Submit each can and end drawing for tooling and compatibility review.
Does the machine sterilize the food?
No sterilization process is established by this seaming description. The source refers to a separate downstream retort process.
What vacuum or residual oxygen value is specified?
Neither a vacuum setpoint nor a measured oxygen result is stated here. Agree any required measurements and limits separately.
What happens after I submit an enquiry?
The form validates the entries and reports that they have not been sent. Live delivery and a formal specification PDF remain pending.
