5. How vertical bagging machine differs from horizontal bagging machine?

Both vertical bagging machine and horizontal bagging machine are popular packaging equipment, and they have similar applications, however, there are some differences between the two machines, which are as follows:

• Packaging Process

You can observe the appearances of the two machines, it is obvious that their working directions are different. The raw material enters the vertical bagging machine from the hopper on the top, while horizontal bagging machine uses a conveyor to deliver raw material. For all operations after that, one of the two machines works vertically and the other one works horizontally.

• Suitable Products

As you know that vertical bagging machine can deal with different forms products such as powders, granules, liquids and semi-liquids. But for horizontal bagging machine, it isn’t suitable for liquid products because of its working direction.

• Bag Style

Vertical bagging machine can provide a wide range of bag styles which are different in shapes and sizes, not only limit in sachet, therefore, it can meet more packaging demands. However, the horizontal bagging machine don’t has such a high flexibility, it can make sachets and pouches.

• Occupied Area

Vertical bagging machine has small occupied area, while horizontal bagging machine need a larger area because of its horizontal layout. Therefore, vertical bagging machine is suitable for factories which have limited spaces.

6. How many components consist of a vertical bagging machine?

Actually, vertical bagging machine doesn’t have a complex structure, it is easy for you to learn the components of this machine, just read the following content.

• Hopper: The hopper is at the top of vertical bagging machine, it is to store the raw materials before they are filled and packed.
• Roll Film Placement Device:You can also call this part as film holder, it is to place and fix packaging film.
• Measuring Cup:This part is used for material metering and unloading, in other word, it is to determine the dose of material, ensure the filling accuracy.
• Control Panel: You can regard this component as the brain of the vertical bagging machine, it controls all working steps of the machine.
• Coder: The function of coding is to print the production date and other information of the product on the packaging film.
• Bag Forming Machine: During the working process of vertical bagging machine, the film is pulled down and come into shape of bags in this part.
• Vertical Sealing Device: The vertical sealing device is to heat seal the two sides of the bag.
• Horizontal Sealing Device: The function of this part is similar to that of vertical sealing device, but the horizontal sealing device is to seal the top and bottom of the bag.
• Cutting Device: This part is to cut off the connection of each two bags so that the finished product can be discharged.

7. What is the working principle of vertical bagging machine?

Totally speaking , the whole working process of vertical bagging machine can be divided into 10 steps, including packaging film unwinding, coding, bag forming, vertical sealing, bottom sealing, metering, material filling, top sealing and cutting & discharging.

• Packaging Film Unwinding: When the vertical bagging machine begin working, the packaging film is pulled out and tensioned by rollers, this step is to make preparation for the bag forming step.
• Coding: Some vertical bagging machine has the coding function, the coder will print the production dates and other information on the packaging film.
• Bag Forming: When the packaging film pass through the bag forming device, it is twisted and folded, at this moment, the packaging bag is preliminary shaped.
• Vertical Sealing: This is the first sealing step, which is to seal the side of the bag. How to achieve this operation? The vertical sealing device is heated and then presses on the side of the bag so that it is perfectly sealed.
• Bottom Sealing: It is not enough that the sides of the bag are sealed, the bottom also need to be sealed, otherwise the material filled into the bag will leak out. Therefore, the next step of vertical sealing is bottom sealing, it is achieved by the horizontal sealing device.
• Metering: Vertical bagging machine is equipped with a measuring cup which is used to measure the dose of material, ensure the accurate filling.
• Material Filling: The bag is now sealed on three sides, which is ready to be filled, therefore, in this step, the measured raw material is fallen and filled into the bag.
• Top Sealing: When the filling process is finished, the horizontal sealing device will seal the top of the bag so that the raw material is packed in it, the packaging process is finished.
• Cutting & Discharging: Even though the raw material is filled and packed in the bag, this bag is still connected to the bag above it. Therefore, in the final step, the machine cut off the connection of the two bags and the finished product is discharged.

8. What raw materials can be packed by vertical bagging machine?

It is obvious that vertical bagging machine can pack many products of different industries, even though the categories of these products are various, in essential, they can be classified into certain forms, such as:

Powders

Vertical bagging machine is able to pack powdered products, such as milk powder, coffee powder, flour, wheat flour, drug powder, seasoning powder, chocolate powder, matcha powder, egg yolk powder, washing powder and so on. When the vertical bagging machine pack powders, it mainly uses the powder screw with the measuring cup for material feeding.

The powder screw is stirred in the hopper, so the powder product is more uniform during the stirring, and then falls into the measuring cup, which plays a role in metering, and next the measured powder product will be filled.

Granules

Also, vertical bagging machine can be used to fill and seal granular products, including but not limited to rice, nuts, beans, grains, seeds, plastic particles, gummy candies, fertilizer, desiccant, tea leaves, etc. The granule vertical bagging machine is specially designed to package these products.

To fill and pack granular products better, the vertical bagging machine is always equipped with a multi-head weigher, which plays a role in weighing and material feeding.

Liquids & Semi-liquids

Besides solid products, vertical bagging machine can pack liquid products, either. The machine can pack liquids and semi-liquids, which include beverages, shampoos, sauces, pastes, yogurts, body lotion, laundry detergent, face cream, various oral liquids, etc. For better packaging of liquid products, you can use a liquid paste vertical bagging machine.

Different from other vertical bagging machine, liquid paste vertical bagging machine adopts a liquid pump which is used for automatic quantitative packaging of liquid and sauce materials. And notice that, if you need to pack viscous liquid product, the liquid pump should be replaced by a rotor pump.

9. What shape bags can be made by vertical bagging machine?

Different products have different packaging requirements. Of course, it is impossible for a vertical bagging machine to provide only one kind of bag style, guess how many shape bags can be made by this machine? Come and learn then now.

3-side Seal Bag

The gusseted bag has good stability, which is because of its shape, the top and bottom are sealed while the two sides are propped up. This kind bag is always used in PET food packaging and fertilizer packaging.

Triangle Bag

Triangle bag is three-dimensional, this bag is sealed on two sides and contains four triangle faces, the compact tetrahedral structure provides great stability. The triangle bag is applied in packaging coffee, tea and snacks.

Double-layer Bag

Double-layer bag contains an inner bag and a outer bag, generally speaking, the inner bag has filter function, this kind of bag is used to pack coffees and teas. Not every vertical bagging machine can provide this bag style, to make double-layer bag, you need to use special vertical bagging machines, which can produce the inner bag and the outer bag, and put the inner bag into the outer bag.
