RS425 Series Thermoforming Packaging Machine
This series covers RS425J-S, RS425S, RS425H, so selection stays inside one platform instead of mixing configurations across series.
Vacuum packaging removes the air around the product and holds the film against it. It is the most cost-effective way to stop oxidation and aerobic spoilage, and it needs no gas supply — only compressed air and power.
The machines below are the ones in our range that can take this job directly. Final selection still depends on tray dimensions, output per shift and how the line connects to what you already have — once those three are fixed, the configuration is mostly settled.

FAQ
What output can I expect for this application?
Across our current models the corresponding rates are roughly: RS425J-S: 2160-2880; RS425S: 2700-3600; RS425H: 2700-3600 (trays/hour). Real output also depends on fill weight, how fast operators load trays and what happens downstream.
How long does a format change take?
It is mainly a mould change: typically 30 minutes to an hour depending on how different the tray formats are. For plants running several SKUs we usually quote the common moulds together so nobody waits on tooling.
What vacuum level should I choose?
−0.09 MPa or deeper for dense products such as cheese blocks and cured meat; −0.06 to −0.08 MPa for soft or fragile products where full vacuum would deform them. The level is stored as a recipe so operators do not have to set it each run.
