Automatic Plastic Film Packaging Machine is a kind of automated equipment widely used for packaging various kinds of products such as food, medicine, cosmetics, daily chemicals and so on. It can quickly and efficiently cut and seal the plastic film and completely encapsulate the products in the plastic film through the automated operating system to ensure the sealing and safety of the products. With the progress of industrial automation and intelligent manufacturing technology, fully automatic plastic film packaging machine plays an increasingly important role in the production line. In this paper, we will discuss the working principle, advantages, application areas and its development trend of automatic plastic film packaging machine.

　　First, the working principle of automatic plastic film packaging machine

　　Automatic plastic film packaging machine is mainly composed of conveyor belt, film release device, cutting and sealing system, heater and control system and other parts. Its basic workflow includes the following steps:

　　Product transfer: The products to be packed automatically enter the working area of the packaging machine through the conveyor belt.

　　Film Placement: The plastic film is pulled out and laid above or below the product through the film rolling device. The packaging machine is able to automatically adjust the tension and width of the plastic film to accommodate products of different sizes.

　　Cutting and sealing: The machine automatically cuts the film and seals it according to the set package size and shape. Generally, heat sealing technology is adopted, in which the opening of the plastic film is heated by a heater to make it tightly sealed to ensure the airtightness of the package.

　　Cooling and molding: After sealing, the bags are processed by the cooling system to form the final finished packages, which are transported to the subsequent production process through the conveyor belt.

　　Second, the main advantages of automatic plastic film packaging machine

　　Efficient production: automatic plastic film packaging machine has a high degree of automation, can greatly improve the packaging efficiency of the production line. Traditional manual packaging is not only time-consuming and laborious, but also prone to inconsistent packaging quality. The automated equipment can realize continuous batch production, to ensure that each product packaging speed and quality consistency.

　　Packaging aesthetics: automatic plastic film packaging machine using plastic film material is flexible, can be tightly wrapped around the product, so that the appearance of the packaged products neat and beautiful, enhance the competitiveness of the products on the market, especially in the food, pharmaceuticals, cosmetics and other appearance-conscious industries.

　　Simple operation, easy maintenance: modern automatic plastic film packaging machine is usually equipped with intelligent control system, user-friendly interface, workers can start to operate after simple training. The automation design reduces the reliance on manual labor and lowers labor intensity. At the same time, the modular design of the equipment makes repair and maintenance more convenient, reducing the downtime of the production line.

　　Good packaging sealing, safety and hygiene: Plastic film packaging has good sealing performance, which can effectively prevent the products from being affected by the external environment, such as air, moisture, dust, etc., in the process of storage and transportation, and is especially suitable for food, pharmaceuticals, and other industries with high requirements for packaging sealing. At the same time, automated packaging reduces manual contact and ensures product hygiene and safety.

　　Reduce the waste of packaging materials: the automated equipment can automatically adjust the length and width of the plastic film according to the size and shape of the product, thus avoiding the waste of materials. Meanwhile, the equipment's efficient sealing technology reduces rework or material waste due to poor sealing, further reducing production costs.

　　Third, the application areas of automatic plastic film packaging machine

　　Food industry: In the food industry, automatic plastic film packaging machine is widely used in the packaging of various foodstuffs, such as cookies, breads, chocolates, frozen foods, instant noodles and so on. Its tight package can effectively extend the shelf life of food, prevent the food from moisture deterioration, while ensuring product hygiene.

　　Pharmaceutical industry: Pharmaceutical products have very high requirements for packaging hygiene and safety, automatic plastic film packaging machine can meet the requirements of the pharmaceutical industry for sealing and sterility. Various medicines, medical devices and other products can be packed by automatic plastic film packaging to ensure that they will not be contaminated or damaged during transportation and storage.

　　Cosmetics and daily chemical industry: cosmetics, skin care products and daily chemical products also need packaging aesthetics and sealing, automatic plastic film packaging machine can provide high-quality packaging for these products to enhance the market attractiveness of the product.

　　Electronic products: automatic plastic film packaging machine is also widely used in the packaging of electronic products, such as batteries, chargers, data cables and other products, through the plastic film tightly wrapped to prevent electronic products from moisture, oxidation or by the external environment.

　　Fourth, the development trend of automatic plastic film packaging machine

　　Intelligent and automated enhancement: with the continuous promotion of industry 4.0 and intelligent manufacturing, automatic plastic film packaging machine is developing in the direction of more intelligent. The future equipment will have a more powerful self-monitoring and automatic adjustment function, able to adjust the parameters in real time according to the production demand, improve the flexibility and efficiency of the production line.

　　Application of environmentally friendly packaging materials: in the context of the global environmental awareness, the future of automatic plastic film packaging machine will pay more attention to the use of environmentally friendly biodegradable materials to reduce the negative impact of plastic packaging on the environment. At the same time, the equipment will further optimize the utilization rate of packaging materials, reduce material waste and lower production costs.

　　Equipment modular design: in order to adapt to the packaging needs of different industries and products, the future of the automatic plastic film packaging machine will pay more attention to the modular design, so that the equipment can be quickly adjusted according to the different products and replacement of packaging components, to enhance the versatility and flexibility of the equipment.

　　Automatic plastic film packaging machine as a modern packaging industry important equipment, in improving production efficiency, ensure packaging quality, reduce production costs and so on play an important role. With the continuous progress of automation and intelligent technology, automatic plastic film packaging machine will continue to be widely used in various industries, and towards a more environmentally friendly, efficient and intelligent direction. For enterprises, choosing the right automatic plastic film packaging machine can not only improve production capacity, but also enhance the competitiveness of products in the market.
