Choosing the right thermoforming packaging machine is an important decision for food processors, medical manufacturers, pharmaceutical companies, and other businesses that require consistent, automated packaging. Promarksvac offers both Mini Thermoforming Packaging Machines and Standard Thermoforming Packaging Machines, giving manufacturers options based on production requirements, packaging formats, available space, and desired machine configuration.
At first glance, the Mini and Standard thermoforming machines share many of the same core technologies. Both use compressed-air forming, air-cylinder sealing, servo-driven film indexing, water-cooled tooling, stainless steel construction, dedicated vacuum valves, and automated controls.
However, they are not identical configurations.
The Mini Thermoforming Packaging Machine is equipped with three loading stations and a Busch 40 m³/hr vacuum pump, while the Standard Thermoforming Packaging Machine provides five loading stations and a Busch 63 m³/hr vacuum pump. They also differ in standard film specifications, discharge configuration, control options, and electrical requirements.
The right machine depends on the product being packaged, film type, package dimensions, production requirements, desired automation, and available options. Products need to be qualified before suggesting machines and options.
What Is a Thermoforming Packaging Machine?
A thermoforming packaging machine forms packages directly from rolls of thermoplastic packaging film. The bottom film is formed into a cavity using a controlled forming process, after which the product is loaded into the formed cavity.
A top film is then applied and sealed to the package. The finished packages are subsequently cut into the required format and discharged from the machine.
This automated packaging process allows manufacturers to produce consistent package formats while controlling film usage, sealing, package presentation, and production workflow.
Thermoforming can be used for a wide range of applications, including food products, meat, seafood, dairy, prepared foods, medical products, pharmaceutical products, and other items suitable for rollstock packaging.
The correct machine configuration depends heavily on the product and packaging application. Film characteristics, product dimensions, required forming depth, package format, production volume, sealing requirements, and optional technologies such as modified atmosphere packaging should all be evaluated before selecting a machine.
Mini vs. Standard Thermoforming Machine: What Is the Difference?
The Mini and Standard thermoforming machines share several important technologies, including:
- Quick compressed-air forming
- Air-cylinder sealing
- Servo motor for film indexing
- 5/8-inch stainless steel conveyor chain
- Water-cooled tooling
- Dedicated top and bottom vacuum valves
- Electronic safety interlock
- Stainless steel construction
- Two independent tool lifting stations
- Easy sealing plate changeover
- Remote diagnostic capability
- Automatic chain lubrication
However, their standard configurations are different.
The Mini Thermoforming Packaging Machine has 3 loading stations, a Busch 40 m³/hr vacuum pump, a 216 mm film index, and a maximum forming depth of 80 mm.
The Standard Thermoforming Packaging Machine has 5 loading stations, a Busch 63 m³/hr vacuum pump, a 216 mm film index, and a maximum forming depth of 80 mm.
