A bubble film making machine is an automatic (Lượt xem: 366)
A bubble film making machine is an automatic equipment that produces bubbles of plastic. The bubble film is made up of several layers. Usually, there is only one extruder per film, but two or more are possible. There are two or three extruders that can produce one to five layers of film. The rewinder part of the machine is used to compound one or two layers of EPE with aluminum foil or other recycled material. It can also produce color bubble film by adding a masterbatch of color. Compound PE air bubble film making machine
Compound PE air bubble film making machine consists of the extruder unit, air bubble forming device, perforation device, cutting device, and cabinet control system. It is mainly used to produce air bubble film with four different universal bubble diameters. It is also suitable for other plastics-based film-making industries. The main functions of a compound PE air bubble film making machine include making air bubble film of various sizes, varying in thickness and quality, and ensuring product safety.
The air bubble film making machine can produce different layers of polyethylene compound bubbles, ranging from six to thirty-two layers. It can also be programmed to produce the films with different weights, from 30gsm to 300gsm. It is also designed to be versatile, allowing it to produce a variety of materials. One air bubble film making machine can produce one or two layers of PE, while another can produce three to five layers. Moreover, these air bubble film making machines can be configured to produce foamed PE sheet or aluminized film. High efficiency
A high efficiency bubble film making machine can produce films in various colors and weights. It is made up of seven parts, including an extruder, forming and cutting unit, winding unit, and edge trimming device. The extruder uses mechanotronics to achieve automatic control. The finished roll can be rewound automatically. Its advantages include its wide range of applications, low investment cost, and fast economic return.
The high-efficiency bubble film making machine controls the bubble diameter and thickness by balancing the blowup ratio and cooling rate. It also controls film tension. The thickness of the film can be adjusted according to the desired quality. Moreover, it is easy to operate and can be operated by anyone. The process is also standardized. It is also a good investment for small enterprises. The following are the key features of a high-efficiency bubble film making machine. Excellent product quality
Bubble films can be manufactured with one or two extruders. These extruders have different degrees of machine direction orientation and blow-up ratios. They are also used to produce various types of bubble films, including anti-static bubble bags, printed bubble bags, and mailer bags. The film's mechanical behavior is characterized in terms of tensile strength, tear resistance, and BUR (transverse direction stretch ratio). All samples exhibit biaxial lamellar structures.
The production process involves two processes, the first of which is the double bubble process. Double bubble process involves reheating and quenching the polymer tube, which results in an uneven orientation temperature. Both processes have different advantages, but double bubble films generally have better orientation properties. The only disadvantage is that the film's crystallinity is lower than that of a conventional blown film, which results in wider thickness variations.
A bubble film making machine can be used for various applications. The process of producing bubbles is simple and involves a downward extrusion of a tube with a blow-up ratio of 1:1. After the bubbles are formed, they are water-quenched to form an amorphous structure with low crystallinity. This structure gives the final product an attractive appearance. Moreover, bubble film making machines can save energy significantly as they are equipped with a variable-speed drive.
The thickness of the finished bubble film can be controlled by balancing the cooling rate, blowup ratio, and tension. It is also possible to make customized bubble bags, such as anti-static bubble bags, printed bubble bags, or mailer bags. All these factors can be controlled with the help of the bubble film making machine. However, it is better to consider the cost of the machine before purchasing one. It is an investment worth making. Types
There are two basic types of Bubble film making machines. One makes bubble films using a melt that exits a die. The other produces films by pulling extrudate through the system at a slow speed. During production, nip rolls are closed so that new film does not pass through the top of the tower. Air is used to blow the bubble to the desired size. The process is repeated several times until the desired thickness of the film is achieved.
Blown films are often used in consumer packaging and for greenhouse applications. They are made using polyethylene resins. These machines are often tall vertical towers. Then the blown film is stretched to the desired thickness and rolled through rollers to create the final product. Depending on the type of film, the machine can make single or multilayered films. Bubble film machines are ideal for small-scale businesses because they are less expensive and easier to operate than other types of film-making machines.
