Henkelman's Marlin vacuum packaging machine is perfect for packing high volumes for food storage and sous-vide cooking. The robust, stainless steel Marlin 52 II vacuum packer is standard equipped with a Busch vacuum pump. Gas flush option is included in the unit. Vacuum packing your products reduces bacterial growth and thereby extends their shelf life. You can also flush the bag with gas such as nitrogen or argon for even longer shelf life. Hermetically sealing the bag prevents cross-contamination of your product from external influences and improves safety. Product is also protected from atmospheric dehydration, freezer burn and mold.
