Automatic L Sealer & Shrink Tunnel
- S5545 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 blade uses the curve 45# carbon steel material integrated knife with USA DuPont Teflon coating which is anti-stick coating & anti-high temperature. So the sealing will not have cracking, coking and smoking with zero pollution;
- Equipped with imported sensor includes horizontal and vertical detection for switching easily, also it’s convenient for packing thin and small items;
- Automatically feeding: the bag length can be auto adjusted by the sensor and time relay. Matched the reduction motor makes the waste film automatically rolling;

- Automatically feeding: the bag 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 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;
- T4525 adopts imported heating resistant insulation curtain greatly reduces heat loss;
- Stainless steel heating elements makes heating up fast. Circulation fan motor assures large volume air transported evenly.
- Operator can adjust the conveyor speed and tunnel temperature to achieve optimal shrink effect according to products’ sizes and output;
- Using solid roller conveyor, external anti-high temperature silicone tube can load heavier objects and rollers will not be deformed;
- Applies to software, food, cosmetics, printing, pharmaceutical, flooring, ceramic, beverages, hardware and other industries’large quantities of shrink wrap.
