How to make a cellophane bag sealer
Heat sealing is the process of welding one thermoplastic to another thermoplastic or other compatible material using heat and pressure. The direct contact method of heat sealing uses a die or hot sealing bar to apply heat to a specific contact area to seal or weld the thermoplastics together while induction sealing uses electromagnetism for the generation of heat needed for welding. Heat sealing is used for many applications, including electronic connectors, thermally activated adhesives and films. A variety of heat sealers are available to bond thermoplastic materials such as plastic films: hot bar sealer, impulse sealer, etc.
Hot melt adhesives can be applied in strips or beads at the point of bonding. It can also be applied to one of the surfaces during an earlier manufacturing step and then reactivated by heat for bonding.
Other containers, such as foil bags or gusset bags, may have several layers that need to be sealed at the same time. Therefore, your sealer should be suitable for multi-layer laminated materials.
Hand heat sealers are a Valdamark specialty. These are machines that we use in our own manufacturing and production facilities by hand. We know and trust them as the best available for professional heat sealing.
Our current range are all lightweight, easy to use machines that create optimum seals consistently and easily. This is essential when performing medium to high volume sealing jobs, as the operator will need a reliable machine that is lightweight to avoid handling fatigue. Most important of all, however, is that the machine is safe to use.
We have machines like the WSZ, which is preferred for thick, multilayer, heavy-gauge industrial packaging, such as supersacks, octabin liners and other export packaging materials. WSZ machines are available in 300 mm and 400 mm jaw widths and can be supplied as standard or with PTFE coated blades.

Then step down and press the handle until the front pilot light of the machine turns on, hold down the handle until the front pilot light turns off, the front pilot light will automatically turn off to indicate that the sealing of the bag is finished, give it a cooling time before removing the bag in order to get a perfect seal, then step down and press the handle until the front pilot light turns on, hold down the handle until the front pilot light turns off, the front pilot light will automatically turn off to indicate that the sealing of the bag is finished, give it a cooling time before removing the bag in order to get a perfect seal.
Then step on and press the foot pedal until the front pilot light comes on, hold down the pedal until the front pilot light turns off, the front pilot light turns off automatically to indicate that the bag has finished sealing, give it a cooling time before removing the bag in order to obtain a perfect seal.
The machines have two Teflon-coated bronze jaws, each of which houses an electrical resistor. The resistors are manufactured from an alloy of Nickel (80%) and Chromium (20%), all inside a stainless steel cartridge guaranteeing a long life span.
Our FR-770 and FR770-LW models are made of AISI304 stainless steel. They can seal and print at the same time a variety of plastic bags of unlimited width at an adjustable speed.
