The SF-300 Sealing Machine made of steel is an essential tool for mushroom cultivation and other applications that require hermetic sealing. Its design allows you to close plastic bags or similar materials by applying heat to the open edges, fusing them to form a strong and durable seal.
In mushroom cultivation, maintaining a sterile environment is crucial. Thanks to its hermetic sealing, the SF-300 prevents the entry of contaminants such as unwanted bacteria or spores and helps maintain the substrate's optimal moisture, promoting healthy mycelial growth.
Main features:
- Maximum sealing length: 300 mm
- Sealing thickness: 0.1 - 0.4 mm
- Dimensions: 41.5 x 14.5 x 8 cm
- Weight: 1.472 kg
- Color: blue
Advantages in mushroom cultivation:
- Maintains the internal moisture of the substrate for optimal development.
- Reduces contamination risk by limiting contact with the substrate.
- Makes handling and transport of sealed bags easier.
With the SF-300 sealing machine, you can work with complete confidence, ensuring firm and precise seals at all times, whether for mycological production or sealing bags in other environments that require secure closure.
