The external suction vacuum packaging machines are made of stainless steel and are easy and quick use. They guarantee a lasting and high-quality vacuum that preserves the quality of perishable products. All models are fitted with an easy to use display and some models are fitted with a LCD display that can be programmed in 5 languages (English, French, Italian, Spanish and German) that describes each stage of the process. Each machine has a professional sealing bar which allows a wider, clearer weld, which guarantees a lasting vacuum. The machines also have a filter to protect the pump from liquids and moisture. All types of fresh or liquid products that cannot be packaged in the embossed bags can be preserved in special jars.
