Sustainable contractors need to understand all of the best building strategies that can help them lower the carbon footprint of their operations and minimize the use of raw materials. They need to use tools that help them reduce the amount of material that is wasted during the building process.

One product that eco-friendly building professionals should be aware of is a stretch wrap pallet. Keep reading to learn more about stretch wrap pallets and their role in sustainable building projects.

The Importance of Stretch Wrap Pallets for Eco-Friendly Building Projects

Stretch wrap pallet, a plastic film that is incredibly stretchable, usually made of LLDPE wrapped around objects. The elastic recovery clings to the part tightly.

Stretch film is used to wrap and secure pallets. To help minimize material waste, avoid disruption to loads, and eliminate worker accidents. The reduction in material waste plays a big role in helping ensure contracting projects are eco-friendly. In our blog post, we go into greater detail about the purpose of stretch film. There are numerous widths, thicknesses, and stretch film configurations available.

The following section discusses the two most popular types of stretch film extrusion for green building projects. The process of extrusion is used to create stretch films and a variety of other flexible plastic products. Visit our website for more details on the extrusion method.

It is also known as cast stretch wrap. It is manufactured using the cast extrusion technique. The casting extrusion procedure is a continuous process that involves melting a thermoplastic material and extruding it onto a chill roll using a flat die that has been softened and re-solidified. This technique makes the Cast stretch film more visible, requires less force to stretch, increases tear efficiency, allows the film to sit quietly on the devices, and provides improved cling. As a result, stretch film is suitable for both computerized and manual grading.

Advantages in Cast Stretch Film Cast stretch film: Itis less expensive than exploded stretch film and is thus more prevalent due to its reduced manufacturing costs. Consumers will also display packaged objects due to increased illumination. In contrast to blown stretch wrap, cast stretch wrap relaxes quietly. In addition, cast stretch film has a double-sided cling, which allows for safe packaging.

Disadvantages of Cast Stretch Film: It does not have the power source that exploded stretch film does. Furthermore, cast stretch film exhibits fewer resistance and memory than blown stretch film.

The burst stretch cover is often referred to as the stretch wrap pallet. The vertical die of the ring slit extrudes this plastic melt to build a thin wall tube. Air is blown through the film tube in the shape of a ball through a crack in the die’s middle. A cooling air ring circulates the film tunnel. As a result of this method, the blown film is more robust and challenging than the cast film. Additionally, the exploded film’s superior technical properties usually result in more substantial holding power.

The benefits of a blown stretch wrap: Include increased load capacity and extensibility. The blown stretch film is a high-end production. Until prolonged, blown stretch film has a higher memory level, which helps preserve product loads. Additionally, increased tear resistance is advantageous when securing loads with sharp boundaries.

Disadvantages of Blown Stretch Wrap – Increased processing costs: The blown stretch wrap is opaque due to the crystallization process. Additionally, the blown film is often very disruptive when rolls are unwound.

Manual vs. Automatic wrappers:

  • Manual (or hand) wrappers:

Extended heart: An expansion of the film’s center serves as a wrapping stick, providing less strength and making the handwork harder.

A simple mechanism protects a film roll, as well as a mechanical braking unit that provides power to allow the film to be extended.

Polar wraps: identical to mechanical braking mechanisms, but they are located at the end of a stretched shaft. The roll and brake are configured ergonomically to eliminate the need for stretching to wrap loads and strains to reach load tops.

Wrappers that reach for the hands. Two lead rollers for the stretch film have a mechanical portion on this one-handed wrapping product at varying speeds.

Windows that operate semi-automatically:

Turntable wrappers: With these options, the box will be packed is supported by a tower that rotates the load compared to the roll of film. The tower is placed inside of a carriage that can be moved to and from a stabilized mast. The load will be extended by rotating it faster than the film can be fed.

A carriage is used to store the film on a vertical ring in orbital wrappers. The load is fed into the rotating eye, and a film is fixed to it. An orbital stretch wrapper is a kind of horizontal ring structure in which the load is fixed. In comparison, a horizontal ring is rotated around the load. It is pulled vertically up and down about it, similar to a rotary arm stretch wrapper.

Rotary arm wrappers: The load is going to be stationary as a arm rotates around it. This system is ideal for loads with lower weights or those with speeds where the load can collapse due to the fast rotational speeds.

  • Winding devices that operate automatically:

Typical fully automated rotary ring wrappers

Automatic wrappers are usually semi-automatic versions of semi-automatic devices. The automated wrappers incorporate a conveyor mechanism that automatically loads, seals, and supports the film on the wrapping machine and automatic devices.

Turntable wrappers: The box to be packed is supported by a tower that rotates the load compared to the film roll. The tower is placed in a carriage that can be moved to and from a fixed mast. Extending the load is achieved by rotating it faster than the film is fed.

Rotary arm wrappers: The load remains stationary as a rotating arm surrounds it. This system is used for light loads or speeds that allow the load to collapse due to the fast rotational speeds.

Rotary ring wrappers: With these types of wrappers, the film is contained in a carriage on a horizontal ring that rotates around the container. It is raised and lowered concerning the load. Additionally, the rotary ring technique is a better balanced solution that requires minor wear and upkeep than other wrapping techniques. Additionally, this wrapper can operate at a total capacity (as many as 160 pallets per hour).

Stretch Wrap Pallets Are Important for Eco-Friendly Construction

There are a number of important tools that eco-friendly building professionals should have in their arsenal. Stretch wrap pallets are some of the most overlooked. You should use them to your full advantage as a green building professional.
