Whether you're looking to increase production capacity, or you just want to improve the quality of your stretch film, you'll need to look into some of the latest features available on stretch film making machines. Among the new innovations available on these machines is the ability to integrate all functions onto a touch screen. This increases productivity and simplifies operations.

Another important feature of these machines is that the entire winding process is controlled using a PLC program. This ensures that the roll quality is consistent across the entire web. It also allows for adjustments to the roll's air gap, which is important for distributing air and hardening the film.

The winding station is divided into three parts. The first part is the extruder. The extruder sends molten resin through a large extruder, which forces the thin layer of film over a drum. It then moves forward. It is a common practice for some winders to need to change rolls often.

Co-extruder

During the co-extrusion process, two or more materials are extruded at the same time through a single die. The process is used to create layered parts, such as tubes and pipes, encapsulated parts, and structural units. The process can also be used to produce food packaging films.

Co-extrusion is used for a variety of applications, from packaging bottles to producing food packaging films. The process involves mixing and extruding materials together to create new, more durable films. In addition to creating layers, the process also allows for the production of multilayer pipes. The resulting material is usually made up of seven or more layers. The number of layers varies depending on the application. The material used for the layer must be able to provide a good level of transparency.

One example of a co-extruder is the FT-500/1000 double layer co-extrusion stretch film making machine. This machine uses several different kinds of resins to produce a self-sticky stretch wrap film. It has high impact strength, tensile strength, and anti-pricking properties.

Production process

Generally, the production process of a stretch film making machine is divided into three main stages. These stages include material preparation, film preparation, and winding. Each stage is important in producing the stretch film.

Firstly, the material is heated and cast into a thin walled tube. Then, it enters a heating chamber and reheats until it is stretched to a specified temperature. The temperature of the film can affect its performance. The optimum temperature for stretching the film is a function of the film type. For example, blown film has better mechanical properties than cast film.

Stretch film can be used in a variety of applications. It can be used for pet food packaging, food packaging, and waste packaging. It can also be used in carrier bags and pallets. The thickness can vary between 17 mm and 23 mm. Some films can be processed into twist wrap film or compression packaging.Bubble film machine

After the first stretching step, the film is cut into rolls. A second stretching step follows to achieve a total stretch ratio of 1:3.3. The film is then compacted and fed into a recycling extruder.

Maintenance

Performing regular Maintenance of Double Layer Stretch Film Making Machine helps in prolonging the lifetime of the machine. It reduces downtime and ensures consistent performance. It is important to keep the machine clean to avoid dirt accumulation and fouling. Maintaining proper lubrication also ensures smooth functioning.

Defective film-on-rolls are fed through nip rolls on top of the cutter-compactor. They are then compacted and fed into the recycling extruder. The recycled film is then processed to produce new film.

The stretch film must have the ability to adhere to other layers and maintain adhesiveness during changes in conditions. This is especially important in machine wrap stretch film, which requires consistent application to ensure holding power.

Film buildup can also cause strain on the motor and bearing, which can lead to costly repairs. It can also prevent the free rotation of the film. It also increases the cost of film by up to 300%.

Decreased tackiness can also lead to an increase in film usage. It is important to clean the rollers with isopropyl alcohol to avoid dirt accumulation and reduce the tackiness of the film. It is also important to clean the rubber on the rollers, as it gets coated with dust from stretch film.
