The Development History of Flow Packaging Machines
The Flow packaging machine is an automated packaging equipment. The invention relates to the Industrial Revolution and the emergence of the bakery industry.
In the late 19th century, with the development of industrial technology and the gradual popularization of machinery manufacturing, a group of machinery manufacturers emerged, beginning to produce and sell food processing equipment. Bread, one of the main foods at that time, became the object of research and invention for new bread production machinery.
In the early 20th century, American bread producers began to use a new packaging form called “Pillow Pack”. This packaging form uses two plastic films to sandwich the bread in between, resembling a pillow in shape, hence the name “pillow packaging”. Pillow packaging machines, also known as flow packaging machines, can automatically wrap products(such as food, pharmaceuticals, cosmetics, etc.) into three-dimensional hanging ear bags or three-side sealed bags to protect storage life, expand sales, and increase product added value.
Food packaging equipment manufacturers began to develop machines that could automatically complete the pillow packaging process, namely flow packaging machines, to meet market demand. After years of improvement and innovation, modern flow wrapping machines have become widely used automated food packaging equipment.
The flow packaging machine is a type of continuous packaging machine with strong packaging capability, suitable for various specifications of food and non-food packaging. It can use transparent film materials without trademarks and preprinted film materials with trademark patterns.
Working Principle of Flow Packing Machines:
At present, industries widely use pillow automatic packaging machines in industrial production. Horizontal packaging machines can be used for high-speed packaging of products with regular shapes in food production, hardware parts, daily chemical products, etc. Servo pillow packaging machines are a higher configuration type of machine using multi-servo control, with features such as fast packaging speed, high efficiency, accurate positioning, reliability, and meeting the needs of automated high-speed operation.
Packaging film feeding rollers drive the packaging film into the bag former to shape it. The feeding conveyor sends the goods into the bag former, undergoing longitudinal sealing and transverse sealing and cutting. The discharge conveyor outputs the finished products.
Advantages of Three-Servo flow wrapper:
1. The HMI interface has a convenient setting of functional parameters, is easy to operate, and has a fault diagnosis function.
2. Three-servo motor drive control, independent control of end sealing, center sealing, and feeding, realizing the synchronous coordination of feeding, film feeding, and transverse sealing and cutting axes, making operation more stable, adjustment more convenient, low noise, and long service life.
3. Packaging bag length is not limited. One can choose fixed-length mode or color mark tracking mode to determine bag length, making bag length more precise, and convenient for docking with production lines.
4. Temperature independent PID control, can use various heat-sealable film packaging materials such as PP/PE, aluminum foil/PE, polyester/aluminum plating/PE, nylon/reinforced PE, paper/PE.
5. Software implements the control system, facilitating functional adjustments and technological upgrades. The transmission system is concise, work is more reliable, and maintenance is more convenient, which is conducive to the installation and commissioning of pillow packaging machines.
6. High-sensitivity photoelectric eye color mark tracking, digital input sealing and cutting position, making the sealing and cutting position more accurate, with features such as anti-empty bag, material cutting stoppage, etc.
7. Materials contact parts are made of SUS304, meeting the hygiene requirements of QS and GMP.
8. The flexible adjustment system and the extensive packaging range. Flow packaging machines can package various specifications, shapes, and properties of items, such as biscuits, potato chips, tissues, soaps, hardware products, paper boxes, etc.
9. Horizontal flow wrappers have a wide range of applications. They can meet the packaging needs in various fields, such as food, daily necessities, medicine, hardware, stationery, toys, etc.
Application Range of Horizontal Packing Machines
The flow packaging machine has a very wide range of packaging objects. It can package many types and shapes of items, including but not limited to:
Food: flow packaging machines can package various foods such as biscuits, bread, chocolates, candies, puffed foods, meat products, seafood, vegetables, fruits, etc.
Pharmaceutical Industry: Flow packaging machines can package tablets, oral liquids, syringes, medical devices, etc.
Daily Chemical Products: Flow packaging machines can package shampoos, shower gels, toothpaste, soaps, gloves, knives, forks, etc.
Industrial Products: Flow packaging machines can package industrial products such as electronic components, stationery, etc.
Flow packaging machines can package a variety of products as long as the products are packaged in plastic bags.
Flow packaging machines are divided into two types: upper film and lower film. The upper film packaging machine is suitable for solid materials with relatively regular shapes, while the lower film packaging machine is suitable for relatively scattered, elongated products with a broader range of packaging. The rear-pull film machine is one of the lower film types, ideal for sticky products, such as candy packaging.
Future Development Prospects of Flow Packaging Machines
There is a significant demand for the flow packaging machinery market. With people’s increasing demand for quality of life, the requirements for packaging forms are also gradually increasing.
Horizontal packaging machinery can meet the requirements of product aesthetics, convenience, easy storage, etc., and has won the favor of the majority of consumers. The demand for packaging equipment is high, especially in growing industries like food and pharmaceuticals. Therefore, the future development space of the flow packaging machinery market is still expansive.
