Cast Stretch Film Line

Cast stretch film is a type of plastic packaging material produced by feeding a sheet of heated resin through a flat die. The resulting film has micro-perforations that are ideal for a range of applications. This type of film was introduced in Asia, where it is currently the only manufacturer. Its lightweight composition makes it an ideal choice for a variety of applications. Although it has a limited range of applications, blown film is preferred for some types of applications, especially construction products. It is a good idea to choose both types of film when considering cost and weight.
Cast stretch wrap is created by feeding a sheet of heated resin through a flat die

Stretch films are essential components of the packaging industry. They offer a cost-effective, versatile solution to many packaging needs. The production process uses a flat die to extrude a sheet of heated resin into a film. AC motors play a vital role in ensuring high-quality output. Read on to learn about the benefits of stretch film and how this process works.

There are two types of stretch film: blown and cast. Blowing stretch film is created by forcing beads of resin through a hot barrel and narrow slotted die. The "sheet" of film then solidifies and is made into rolls. Compared to blown stretch film, cast stretch film is less labor-intensive, quicker, and cheaper. The final product is perfect.
It produces micro-perforated film

Stretch films are a necessity for the packaging industry. They offer a high-quality and economical solution to packaging problems. The process of manufacturing stretch films is done with a flat die extrusion. AC motors play an important role in ensuring that the film is of a high quality. Generally, a stretch film consists of multiple layers of resin, each of which is extruded.

Metallocene resins are specially made for stretch film manufacturing. Metallocene resins are manufactured with a catalyst that allows Exxon to incorporate the properties desired for stretch film. Pactiv, another company that produces these films, uses the cast film manufacturing method for its metallocene resins. Until September 1995, large panels were placed into corrugated boxes or polyethylene bags.
It is suitable for a range of applications

A Cast stretch film line is a flexible and economical packaging solution for a variety of applications. It is traditionally produced from polyethylene or polypropylene, but is also available in other materials such as EVOH or nylon. PE is the most popular choice for stretch-wrapping because of its high tensile strength and excellent cut-ability. PE also provides the greatest economies of scale for producers. The stretch-wrap market in Europe saw growth of five to seven percent in 2004, with a total production of 1.1 million tonnes. It was further divided into hand-wrap and machine-wrap.

The UVI Stretch Film line is suitable for a wide variety of applications. It is especially suitable for wrapping small packages, multiple boxes, and pallets. It reduces the risk of denied freight claims, limits visibility, and improves security. UVI Stretch Film can also help you easily identify your products, as it offers 10 colors to match your packaging requirements. It is also recyclable. You can contact a local recycling facility to determine whether it is accepted for recycling.
It is the first manufacturer in Asia

The latest cast stretch film line has been launched by Davis-Standard in Asia. The dsX inline pre-stretch line was first launched at K 2013 and will serve the fast-growing stretch film market in the region. As part of the expansion, Davis-Standard plans to set up a spare parts and service center in its new facility in China. The company already operates one manufacturing plant in Asia and regards China as an "important" market.

The production process of cast stretch film involves an entirely different chemical process. Resin, often called polymeric feed stock, is delivered to the production line in the form of small plastic pellets. The process of creating this film is complex, and each individual film may have several layers of resin. The resin is then heated and compressed in a process known as extrusion. The result is a continuous layer of plastic.
It is equipped with a cooling unit

A cool air stream provides an optimum temperature for the stretch film extruder. This cooling unit ensures a fast changeover of materials while minimising thermal stress on the polymer. Moreover, it reduces barrel heating energy and heat emission. Since the raw materials constitute 80 per cent of the total cost of stretch film production, it is vital to use them as efficiently as possible in all film layers. A cooling unit on the Cast stretch film line helps in this.

The cooling unit on a Cast stretch film line consists of two rolls: the primary quenching roll and the secondary quenching roll. The first chill roll has an electro-chemically matted surface that ensures homogenous cooling and ease of film release. The second chill roll is polished and has a higher cooling capacity. Both rolls are fitted with separate drives and water tempering systems. The cooling unit can also include infrared, X-ray, or beta-ray sensors for enhanced film quality.
It has a surface-center winderStretch film making machine
A cast stretch film line with a surface-center winder offers a number of benefits. It allows the film to be wound on adjacent cores on one shaft, avoiding the wasteful bleed trim. The winding process is operator-friendly, incorporating two 17-inch touch screens that handle all functions needed for running the entire line. One touch screen deals with input of raw material ratio and the other controls winding parameters. A second touch screen linked to the main terminal allows for winding parameter adjustment directly from the operator's field of vision. It is also equipped with different levels of access and has features such as alarm management, recipe administration, and remote service via ethernet or internet.

Another advantage of this type of line is its high output. Cast film is the most efficient method of producing stretch film in a high output range. The SML team continually develops core components to improve the production flexibility of their stretch film lines. The company offers standard solutions for widths ranging from three to twelve up and custom lines based on these concepts. The range of options includes hand-stretching systems and inline winding on 2-inch cores. The company also offers coreless winding systems and various layers and structures for a wide range of output requirements.
