What is a trayless bread packaging machine?

An automatic flow packaging machine for packaging breads without a tray, also known as a trayless packaging machine, is an automatic horizontal packaging machine. Trayless packaging is different from ordinary packaging with trays. The packaging machine can automatically pack multi-piece regular-shaped products without needing a tray. 

The most significant advantage is that it saves trays and reduces the manufacturer’s production costs. The packaging without a tray has a beautiful and elegant appearance. Removing the tray can reduce the overall packaging size, which is convenient for consumers to carry when traveling. It is suitable for packaging multiple rows of regular objects, such as bread, steamed buns, steamed twisted rolls, wontons, and other products without trays.

How does the trayless packaging machine work?

Trayless packaging machines usually adopt an upper film roll structure. Its working principle is that the packaging film enters the former through the packaging film driving roller and then formed. After the packaged items are fed into the former by the feeding conveyor, they are sealed longitudinally, transversely sealed and cut, and output by the discharge conveyor.

Workflow overview

The workflow of the multi-row bread packaging machine has the following steps: preliminary arrangement of multiple breads, automatic transportation of breads, supply and shaping of packaging materials, packaging of bread, and discharging of finished product.

Detailed workflow:

1. Preliminary arrangement of bread:

Operators manually feed the breads onto the feeding conveyor. The feeding conveyor will transport the products to the next working station. 

2. Automatic conveying of bread:

The conveyor belt transports the arranged bread to the bag forming position of the packaging machine at a certain speed.

The design of the conveyor belt ensures that the bread will not tip over or become dislocated during transportation.

3. Supply and forming of packaging materials:

The packaging roll film enters the bag former through the packaging film driving roller. It passes through the forming device to form a packaging shape suitable for bread.

The forming device adjusts according to preset parameters to accommodate products of different sizes or shapes.

4. Bread packaging:

After the feeding conveyor feeds the packaged materials into the bag former, the central and horizontal sealing devices perform longitudinal sealing and transverse sealing and cutting.

5. Finished product output:

After packaging, the output conveyor will discharge the finished products.  

Advantages of trayless bread packaging machine:

1. It adopts a three-servo control system, has a wide application range, flexible packaging, and simple operation.

With an anti-empty bag function. It runs when there is material and stops when there is no material, so no film is wasted.

It has an automatic memory function that can store parameters without repeated settings.

2. Multiple rows of bread can be processed at the same time, which greatly improves packaging speed and production efficiency. Compared with traditional single-row packaging machines, it can significantly reduce packaging time and meet mass production needs. 

3. Quick-frozen foods such as steamed buns, and steamed twisted rolls can be packaged without trays, which can also save the cost of a tray.

4. Exquisite packaging can enhance the product’s image and market competitiveness. Multi-row trayless bread packaging machines can provide stable and beautiful packaging effects to meet consumer demand for high-quality products.

5. Can be equipped with a date coding device.

6. All food contact parts are made of 304 stainless steel, which is safe and hygienic.

To sum up, the multi-row trayless bread packaging machine has the advantages of high efficiency, space-saving, high degree of automation, strong flexibility, hygiene and safety, material saving, and improved product image. These advantages make it an indispensable part of the modern food packaging industry.
