Vacuum inflatable packaging is to put food into a packaging bag, pump the air in the packaging bag to a predetermined vacuum degree, and then fill it with nitrogen, carbon dioxide, oxygen, ethylene and other gases, and then complete the sealing process. CH-A600 vacuum nitrogen filling packaging machine is a semi-automatic multifunctional packaging machine which adopts the most advanced packaging technology in the world and integrates nitrogen making, vacuumizing, nitrogen filling and heat sealing. The process is automatically controlled by PLC programming system and displayed by large-screen LCD touch screen. The time of each working link can be adjusted independently according to different packaging materials and volumes, or one of them can be used alone. The whole machine consists of oil and water removal air filtration system, air separation nitrogen production system, vacuum pumping system, gas storage and gas supply system, heat sealing system, PLC programming control system, lifting studio, frame and casing. The machine can be used with other equipment and production machines. Suitable for all kinds of packaging of plastic composite film and plastic aluminum foil composite film. Liquid, semi-fluid, solid particles, powder, paste food, fresh fruits, vegetables, rice, flowers, chemicals, precious medicinal materials, precious calligraphy and paintings, electronic components and various moth-proof, anti-corrosion, moisture-proof, mildew-proof and antioxidant articles are vacuum packed or vacuum packed to extend the shelf life.
