Types of Stretch Film Machines
The different types of Stretch Film Machines have different purposes. The types that turntable stretch wrapper uses are commonly used for packaging products ranging from a single sheet of cardboard to a large box or crate. The types that spin also vary, and these types are useful for packaging light loads or those that wouldn't tip over at high speeds. To learn more about the different types of Stretch Film Machines, read on. You'll be able to decide which is best for your needs.
Cast stretch wrap
A cast stretch wrap machine is the heaviest type of stretch film available, so it is ideal for heavy-duty pallet loads. Its load capacity is limited by the gauge, so the recommended weight limit is only a guideline, not a specification. You can find a gauge conversion chart, as well as technical stretch wrap data, here. The film used in a cast stretch wrap machine is much more durable than the blown variety.
The process of casting stretch film involves feeding a thermoplastic substrate through a heated screw barrel and a narrow slot die. The thermoplastic material melts as it passes through the die, and then quickly solidifies as it is transferred to the chill roll. The cast film unwinds quietly and offers superior clarity and tear resistance. You can buy cast stretch films in different widths and thicknesses. Depending on the thickness of your packaging, you can choose from a wide range of thicknesses and widths.
Blown stretch wrap
A blown stretch wrap film machine produces high-quality woven stretch wrap. This film is made by a process called blown extrusion. The plastic melt is fed into an annular slit die and then extruded through the machine, creating a thin-walled tube. After the material has passed through the die, air is pushed into the tube to cool it. The resulting film is more rigid and strong than cast films and can hold more weight than cast wraps.
Bubble film machine
Blown stretch film is often more expensive than cast stretch wrap. But it's a better choice for many applications because it provides a higher degree of clarity, has a lower micron value, and unwinds quietly. Blown stretch wrap also enables users to down-gauge to a thinner film, saving money and reducing plastic waste. This type of film is usually used for heavy-gauge products such as timber, pulp, and construction products.
Turntable stretch wrapper
A turntable stretch wrapper is a high-profile, economical pallet-wrapping machine. It features an exclusive roping device and Logo Wrap feature that previously only was available on the Octopus line of ring stretch wrappers. The roll raises and lowers as the load rotates, applying an even layer of film across the entire load. Turntable stretch wrappers are ideal for low and medium-volume packaging applications, and can stretch wrap 20 to 40 loads per hour.
The Wulftec SMH-HVY high-volume turntable stretch wrapper is a semi-automatic, extra heavy-duty system that can wrap up to 30 loads per hour. The SML-200 low-profile stretch wrapper has a standard base and a 77-inch turntable, ideal for large pallet loads. The SML-EXT model has a 2-foot extension for additional wrapping space.
LLDPE stretch film
An LLDPE stretch film machine produces three and five-layer films. Its design was based on years of manufacturing experience and is highly efficient, energy-efficient, and simple to use. Its components include an LLDPE stretch film machine, a manipulator equipment, and a static state mixer. In addition to the extruder and feedblock, it includes a feedblock and a die. The LLDPE stretch film machine can be customized to suit various production requirements.Stretch film making machine
The film is usually made with two different types of plastic films: blown and cast. Blowing stretch film produces better quality films and is generally more expensive. Cast stretch film machines produce lower-quality stretch film that does not meet industry specifications. However, once the film is made, it can be recycled into floor tiles and trash liners. These types of plastic materials are recyclable and can be recycled as many as seven times. This makes LLDPE stretch film a valuable resource for the environment.
