Laboratory Heat Sealer- Model No. PLHS-24 (500 mm)
Rating
5/5Model PLHS-24
Heat Sealer Prima is a consistent tool used to perform sealing on flexible packaging products and other thermoplastic materials using pressure and heat by maintaining high temperatures. A heat sealer is used to measure the heat seal performance of composite films, plastic films such as PP, PE used in packaging different food products such as milk powder, instant noodle, food, washing powder, and drugs.
The Presto (Pneumatic Model laboratory) Heat Sealer is widely used in the plastic industry. The temperature of the Presto Heat sealer is also adjustable. The instrument has been provided with Digital Display and is Microprocessor based.
Both the upper and lower jaws of the Presto Heat sealer are heated separately with separate temperature sensors and controllers. Thus, it is possible to maintain both jaws at different temperatures. It is even possible to switch off one heater, while keeping the other on.
