GENERAL INTRODUTION

Heat Sealer with automatic double folding & sealing packaging machine is a kind of environment-protective packing machine. It is suitable for packing sack weighing from 25~50kg, and it is suitable for packing monolayer or multilayer kraft paper bag, paper plastic compound bag and inner plastic bag etc. This machine can automatically achieve operation procedures of dedusting (optional), inner bag sealing, pinching, trimming & impressing, first folding, flattening, second impressing, second folding, tape sticking and sealing etc.
The packed bag will have excellent sealing performance and fastness, which owns the advantage of dust-proof, damp-proof, pollution proof and could protect the packing product appropriately. (Heat sealer/heat sealing machine)

Feature：

• Dedusting mechanism is optional, which is used to remove the dust on bag opening.
• Adopting controllable constant heating device for heating and pinching inner plastic layer to keep air-tight.
• Adopting inner bag sealing, bag opening-folding for two times, hot melt tape sticking on one side to prevent folded bag opening from rebounding.
• Adopting step motor to draught tape which will be cut according length automatically. The relevant actions will be achieved stably and reliably.
• Adopting swivel heater for heating tape so as to achieve instant sticking.
• Transmission mechanism adopts tailor-made gripping chain to keep packing bag feeder and conveyor working in-phase.
• The whole machine completes the whole process of packing automatically according to programmable procedure by PLC.

This machine can form production line by being equipped with conveyor, and it can form automatic production line with devices for auto weighing, auto filling, auto turning & falling, auto line-up, auto palletizing, auto strapping and auto film wrapping etc.
