How to use plastic wrap? Plastic wrap is something that many families have. It can be used to wrap food to prevent bacteria from invading, and it can also be used to prevent the smell between foods. But can you use plastic wrap? Let's share how to use plastic wrap for plastic packaging.

How to seal 1 plastic bag with plastic wrap (plastic wrap) The best sealing method is heat sealing;

1, heat with a saw blade, and then roll the plastic film. Absolutely practical, the effect is super good! The effect is the same as that of the sealing machine! But if you don't want to use this, you can just take a stick, roll up the bag to be sealed first, and then heat it with a small fire. It won't take long, but it will take some time, so that the bag won't burn.

Or there is a simpler way: bake the plastic bag soft with a torch, then leave the flame and pinch your mouth with your hands. If you think these methods are not good, you can only use a professional sealing machine, which is very beautiful and firm.

2. Turn on the electric iron (this one has it). When the temperature is almost the same, use a straight line at the back (because both sides are curved and the front is sharp, which is not easy to use), put an iron plate or something hard under it, and just press it with the electric iron at the back (the time can be controlled by yourself, maybe two seconds, depending on the temperature, but it is best not to be too high, 100 degrees).

Plastic sealing machine is suitable for aluminum foil bags, plastic bags and composite bags in medicine, pesticide, food, daily chemical, lubricating oil, meat products, seafood, fruits and vegetables, pickles, chilled meat, pharmaceutical products, hardware components, medical devices and other industries. The sealing machine is redesigned and manufactured on the basis of advanced models at home and abroad, and also has vertical and horizontal sealing functions.

Suitable for sealing and bag making of all plastic films. It is an ideal sealing device for food factories, cosmetics factories and pharmaceutical factories. It can run continuously and print the date and batch number according to the needs of users. Suitable for assembly line operation.

Principle and structure

The universal sealing machine consists of a frame, a deceleration and speed regulation transmission mechanism, a sealing and printing mechanism, a conveying device and an electrical and electronic control system.

When the power supply is turned on, all the mechanisms start to work. After the power supply is turned on, the electric heating elements generate heat, which causes the upper and lower heating blocks to heat up sharply, which is adjusted to the required temperature by the temperature control system. The pinch roller rotates, the cooling system starts to cool as required, and the conveyor belt rotates, which is adjusted to the required speed by the speed regulating device.

When the package containing articles is placed on the conveyor belt, the sealing part of the bag is automatically sent between two running sealing belts and brought into the heating zone. The heat of the heating block is transferred to the sealing part of the bag through the sealing belts, so that the film is heated and melted, and then passes through the cooling zone, so that the surface temperature of the film is appropriately reduced.

Then the Hua Lun (or printing wheel) rolls to make the upper and lower plastic films of the sealing part stick together and press out the net pattern (or printed logo), and then the sealed packaging bag is sent out of the machine by the guide tape and conveyor belt to complete the sealing operation.

Cleaning and maintenance

Regularly clean the machine surface, bottom plate, lower die slide plate, groove, upper die inner pressure plate and positioning rod (note: the power supply must be turned off to restore the room temperature). Regularly lubricate the lower die slide plate, pressure bar bearing, eccentric wheel, guide post, guide rail and other transmission parts to ensure the performance of the machine.

The method of cleaning the toothed cutter: firstly, plug the two drainage holes of the lower die with cotton balls, pour boiling water into the groove of the lower die until it is full, then push the sliding plate of the lower die into position, press the upper die down to the lowest point, and let the toothed cutter soak for a few minutes until it is clean, and repeat several times.
