• SF-400LA is a fully automatic unmanned operation “L” type sealing machine which is widely used in mass production packaging line with high efficiency. Automatic film feeding punching device, manually adjustable film-guide system and feeding conveyor platform make the machine suitable for different width and height items.
• Sealing knife uses the curve CR12 steel with DuPont Teflon which is anti-stick coating & anti-high temperature. So the sealing will not have cracking, coking and smoking with zero pollution;
• Equipped with imported photoelectric of horizontal and vertical detection for choice to easily finish the sealing of thin and small items;
• Automatically-feeding: the length can be auto adjusted by the sensor and time relay. Matched the reduction motor makes the waste film automatically rolling;
• When the packaging size changes, the adjustment is very simple by rotating the hand wheel without changing molds and bag makers;
• Different size products can also be packaged combinations to achieve the promotional effect;
• Using original Autonics digital temperature controller which built-in PID function. Sealing blade temperature is extremely sensitive and accurate and we can be arbitrarily set. Do not worry about hurting the product for imprecise temperature. The sealing blade itself is also equipped with automatic anti-cut protection function which effectively prevent from accidental cutting;
• The machine is equipped with organic glass shield with automatic opening alarm function which greatly improves safety;
• The entire machine realizes unmanned operation with the production line connecting;
• Film up-down synchronization mechanism specially designed to correct the deviation film;
• It applies to software, food, cosmetics, printing, pharmaceutical, flooring, ceramic, beverages, hardware and other industries’ large quantities of shrink wrap.
• SF-4020G adopts advance bottom circulation blowing technology, full use of heat to arise energy efficiency. Adjustable blowing direction and volume from bottom side to get a uniform shrinking appearance on the top and bottom of product.
• Visible window shows shrink process inside tunnel, the top of tunnel can be opened for easy clear and maintenance;
• The heating elements are stainless steel which has a long life span and high energy efficiency;
• The use of French Schneider inverter controls transmission speed which has the function of infinitive speed;
• Imported insulation curtain greatly reduces the heat loss;
• The shrink temperature, conveyor speed and air volume are adjustable;
• The conveyor uses new types of rollers covered with durable imported fiber tubes which have the functions of anti-high temperature, wear resistance, non-film damage, non-deforming and long terms using;
