Automatic sealers 12" to 18" wide are designed for the continuous and repeated sealing of thermoplastic materials. Depending on the model of the sealer, material up to 32" wide and 8 mil thick (16 mil total) can be sealed. The seal widths are 2mm to 10mm. They are equipped with an electronic timer and an electromagnet for opening and closing. They operate on impulse sealing; controlled by a plug-in transistorized circuit board. Auto sealers have programmable timers for heating, congealing and recycling cycle that, once set, will give you consistent seals automatically. Use the wider seal widths for the more robust liquid tight seals needed for food products. Our sealers seal poly bags and any thermoplastic material such as polyethylene (PE) and polypropylene (PP) quickly and efficiently. Other materials also may be sealed. No warm up time is needed.
