Typical equipment for bag sealing and plastic sealing:
The material you wish to seal or close is placed between the ”jaws”. The sealing process starts and the material is welded together, cooled and then if the machine is capable, cut at desired length depending on the Sealer type and feature.
Bag Sealers works by heating the material using either constant or pulse heat during activation. The process is also called plastic welding, PE welders bag closers and they can all be used for welding of heat-weldable materials.
What to pack using a bag sealer:
Everything, from magazines, newspapers, catalogues, books, fruit, vegetables, postcards, Christmas ornaments, screws, fittings, liquid, powder, spices, candy, coffee, tea, rice, oatmeal, cream, bread, cakes, etc.
It is not recommended to seal materials by evaporation which are toxic or cause discomfort if inhaled. It should be performed in properly ventilated areas.
Bag and Film Types:
Bag Sealers, Impulse Sealers, Constant temperature welders, using welding rods to produce heating. These are found in typical widths of 2, 5 and 10 mm round flat and have threads with different diameters. A round wire is used as a cutting wire.
The welding temperature is in the range 180-280°C.
Types of Equipment - The following equipments applied:
Other types and variants
An important part that wear out on a bag welder is the Teflon
protective foil. Teflon is used to protect the hot wire to the plastic so no plastic particles are transferred to the welding wire and then it will burn and form of an ash / slag. The quality of Teflon protection are different from machine types and the included instructional manual can be studied to know the correct structure.
