Introduction to Packaging Machines

Packaging machine It is a machine used for packaging products, serving both protective and aesthetic purposes. Packaging machines can be broadly categorized into two main types: 1. Production and packaging along an assembly line; 2. Peripheral packaging equipment for products.

Packaging machine Application

The integrated production and packaging line is suitable for filling (filling), sealing, and coding products in the food, pharmaceutical, daily chemical, hardware, lighting, and furniture industries (for both bagged and bottled products).

The main products include: liquid (paste-like) filling machines, pillow-type packaging machines, horizontal packaging machines, vertical packaging machines, powder and granule packaging machines, automatic bag-filling packaging machines, and automatic packaging machines for frozen products, among others.

As people’s living standards continue to improve, the demand for various convenient foods has also risen significantly, further boosting the rapid development of China’s food packaging industry. Vacuum packaging machines are among the fastest-growing types of packaging machinery and boast tremendous growth potential. There are many different kinds of vacuum packaging machines. Let me introduce them to you below.

Packaging machine definition

The equipment that often places packaged goods outside a vacuum chamber to complete vacuum packaging is called a vacuum packaging machine.

Packaging machine Principle

The vacuum packaging machine places the product to be packaged into a packaging bag via a suction nozzle, evacuates the air from the bag, and then seals it by closing the nozzle.

Packaging Machine Features

1. By removing some of the air (oxygen) from the packaging container, food spoilage can be effectively prevented.

2. By using packaging materials with excellent barrier properties (airtightness), advanced sealing technologies, and stringent quality requirements, it is possible to effectively prevent the exchange of substances within the packaged contents, thereby avoiding weight loss and deterioration of taste in food products and preventing secondary contamination.

3. The gas inside the vacuum-packed container has been removed, which accelerates heat transfer, thereby improving the efficiency of thermal sterilization and preventing the packaging container from bursting due to gas expansion during thermal sterilization.

In the food industry, vacuum packaging is widely used for products such as chicken legs, ham, and sausages. An increasing number of preserved foods—such as pickled vegetables, soybean products, and dried fruits—are also being packaged using vacuum techniques. Vacuum-packed foods have a longer shelf life, significantly extending their expiration dates.

Precautions for Packaging Machines

When selecting a vacuum packaging machine, you can't simply choose a model based on its model number alone. Generally speaking, since different users produce different types of food (and packaging), the package sizes also vary.

Form

Vacuum pump, motor, vacuum chamber, sealing strip, acrylic cover plate, air bag, solenoid valve, and others.

Packaging machine Technical Specifications

1. Feeding and discharging method: Discharge forward and to the right.

2. The compression vacuum packaging machine employs a fixed, instantaneous heating method using a hot chamber, which saves energy.

3. Special electric heating arrangement ensures uniform heat distribution.

4. The body is compact and occupies a small footprint.

5. Vacuum packaging machines suitable for small-batch and medium-batch production, which can be integrated with assembly lines to enhance efficiency.

6. Imported from Taiwan Province, Japan, and South Korea; stable and reliable performance.
