What Is a Plastic Sealing Machine

 

 

The key function of a plastic sealing machine is to bind layers of plastic together. The sealed pack offers protection of the contents from contamination and leakage, as well as enabling efficient handling and secondary packaging.
The sealing process includes binding two sides of a flexible plastic bag or pouch, through to sealing a rigid tray with a film lid. The seals are commonly created by heating the plastic and applying pressure by means of a sealing bar.
Plastic and other materials can be sealed with glue and adhesives, usually with the application of heat to melt the binding agent in a process known as hot melt gluing. Adhesives are most commonly used to apply plastic films to trays.
Rigid plastic tubs are commonly sealed by clip fitting a lid with a gasket, while packaging lines for plastic bottles and jars apply a screw cap to seal the container. Sealing machines for rigid plastic tubs, jars and bottles are known as capping machines.

The Working Principle of the Plastic Sealing Machine

 

The working principle of the plastic sealing machine: Its working principle is simpler and easier to understand than those of larger packaging equipment such as shrinking machines.
When the package containing the heat-shrinkable film is placed on the heat-sealing film conveyor belt, the sealing part of the bag is automatically sent between the two sealing belts running the heat-shrinking gun and brought into the heating zone, and the heat of the heating block is transmitted through the sealing belt to the sealing part of the bag, the film is heated and softened, and then through the cooling zone.
The surface temperature of the film is appropriately lowered, and then it is rolled by the knurling wheel or the printing wheel, so that the upper and lower plastic films of the sealing part are bonded and pressed into a net pattern or the logo is printed, and the sealed packaging bag is sent out of the machine by the guiding rubber belt and the conveyor belt, and the plastic sealing machine completes the sealing.
The assembly part of the plastic sealing machine is composed of a frame, a transmission mechanism for slowing down and speed regulation, a printing mechanism during sealing, a conveying device and an electrical and electronic control system. After the plastic sealing machine is connected to the power supply, each mechanism can start to work.
The electric heating element is heated by electricity, so that the temperature of the upper and lower heating parts rises sharply. The temperature can be controlled to adjust the system to the required temperature. The impression wheel rotates according to the cooling system needs to start cooling, and the conveyor belt is transferred and adjusted to the required speed by the speed control device.
The plastic sealing machine adopts electronic optional precision temperature controller, sealing and printing are automatically completed at one time, and can seal any kind of heatable film. The plastic sealing machine is the development and application of modern technology. It is easy to operate and uses delicate ptfe-coated sealing tape. Nowadays, whether it is heat-sealing film food, cosmetics, clothing and shoes, or heat-sealing film chemicals, electrical appliances, medicine, tea, dairy, beverages and other fields.

Applications of Plastic Plastic Sealing Machine

 

Plastic sealing machines are used widely in the chemical, medical, and pharmaceutical industries. Plastic sealing machines are also used to process food, beverages, cosmetics, electronics, and semiconductors.
End of line machines get the package ready for shipment. This may include bundlers (also called sleeve wrappers), palletizers, pallet wrappers, plus the conveyor system needed to transport the products. Additional equipment is used to apply labels or print on the box.
Uniform case sealers should be used for production runs of cases of the same size. They can be physically reset between cases of boxes.
Random case sealers are used when each box size can vary randomly, such as in order picking warehouses. The machine automatically adjusts to the size of the box as presented. Random case sealers are for lower volumes and more expensive than uniform case sealers.
Standup pouch filling machines are use for products displaying on a shelf (i.E. Bottled products). They use individual bags which are fed into the machine. Standup sealers can be used to fill powders, granules, or liquids into the pouch.

As the name implies, constant sealing machines provide permanent heat, and are designed for use in continuous packaging operations. The elements in impulse machines are heated only while they are sealing a bag or pack.
Impulse heat sealing machines start with entry level equipment capable of sealing up to 20 packs per hour. They are low cost, and use relatively low amounts of energy. However, they are generally only designed for use with lighter grade films. As such they are suitable for smaller operations such as artisan food producers and low volume retail stores using manual operation.

Q: How does a plastic sealing machine work?

A: To heat seal plastic, the essential requirements are heat and pressure. Whether they are impulse or constant machines, heat sealers feature one or more electrically heated elements which press against the open end of bags or the open sides of folded films.
The heating elements are usually in the shape of a bar which spans the top of the bags or films being used. Simple impulse sealers are most likely to feature a single electrically heated bar which melts the layers of plastic at the aperture of a bag.

Q: Why is plastic sealing machine not sealing?

A: Check the heating element and both PTFE pieces found under and over the heating element. Most often the problem with the sealer is that the PTFE & heating element are damaged/broken & need replacement. Please note that both element and PTFE will burn out with wear and tear and a replacement kit will fix this issue.
