When it comes to protecting and securing palletized loads during transit and storage, stretch wrap is an ideal option. But to get the most out of this packaging material, you need to make sure that you choose the best thickness for your specific application.
The thickness of a stretch wrap film is one of its key performance characteristics as it affects the properties and performance of the film. As such, choosing the correct thickness is paramount to ensure that your palletized loads are secure and protected during transit or storage.
With this in mind, there are several key factors you need to consider when selecting the appropriate stretch wrap thickness for a specific application:
Understanding Stretch Wrap Thickness:
The thickness of stretch wrap is usually measured in either gauge (ga), mils (1/1000 inch) or microns (µm). In general, the higher the number, the thicker and stronger the material.
For example, a heavy-duty stretch film may be rated at 125 – 150 gauge while a lighter duty film may be rated at 80-125 gauge.
Strength and Durability:
The strength and durability of stretch wrap are directly related to its thickness. Generally speaking, thicker films such as those ranging from 120 to 150 gauge provide the most security for heavy loads. Thinner films, on the other hand, can yield some savings in terms of cost but tend to offer less strength and puncture resistance.
It is important to note that while thicker stretch wrap may be more expensive, it generally requires fewer wraps per pallet so the overall cost savings can be significant in the long run.
Stretchability and Yield:
Another important factor to consider when selecting a stretch wrap is its ability to stretch and yield. Stretch wraps are either designed to be highly or low-stretch, depending on application.
Low-stretch films tend to provide greater holding power since they require more hand force for application but less stretchability. This makes them better suited for lighter loads (such as boxes).
High-stretch films, on the other hand, are highly elastic and stretchable so they can provide greater coverage with fewer wraps. This is ideal for heavier loads (such as pallets) since it can result in significant cost savings.
Load Handling and Transit Conditions:
Finally, it is important to consider the conditions under which the stretch wrap will be handled and transported. Temperature, humidity, and even outdoor exposure can all play a factor in the type of stretch wrap chosen for a particular application.
For instance, thicker films are typically better suited for cold temperatures since they maintain their shape better than thinner films and provide greater puncture resistance. On the other hand, thinner films are less likely to break when exposed to extreme heat (such as in a hot warehouse) and can provide better load containment.
It is also important to consider whether or not a stretch wrap will be used outdoors since wind can be an issue with some lighter films. Thicker films tend to offer greater stability in windy conditions and are less likely to be damaged or cause damage to the load.
Different Thickness Options:
When selecting a thickness for a specific application, you should consider the size of your palletized load, the weight of each pallet and the environment in which it will be transported or stored.
Below is a quick guide to help you determine the best stretch wrap thickness for your application:
Light Duty – 40 – 80 Gauge (10-20 µm) – Recommended for holding light objects and relatively small loads.
Medium Duty – 80 – 125 Gauge (20-32 µm) – Recommended for heavier items and larger palletized loads.
Heavy Duty – 125 – 150 Gauge (32-38 µm) – Recommended for extra heavy, unstable or sharp edged items. Can also be used to secure large, bulky and lightweight items.
In addition to these standard thicknesses, there are also stretch wraps available with special properties such as higher puncture resistance and UV protection. For applications where durability and strength are of the utmost importance, it is highly recommended that you use a high-quality stretch wrap film to ensure maximum security for your loads.
Also note that some suppliers may offer custom thicknesses to meet the specific needs of their customers. As such, be sure to check with your supplier before purchasing stretch wrap for your application.
Finally, it is essential that you select the right gauge and widths for your items in order to ensure that they are safely and securely wrapped during transport or storage. Choosing the wrong thickness can not only lead to premature failure, but also increase your chances of having a product damaged during transit. For this reason, it is important to select the right thickness for each application in order to ensure the safety and security of your products.
Conclusion
Stretch wrap thickness is an essential factor when selecting the appropriate packaging for your items. By considering factors such as weight, size, and durability of the item to be wrapped, you can ensure that you are selecting the right thickness for your application. Additionally, it is important to check with your supplier regarding custom available thicknesses should they exist. Doing so will help ensure that your items are securely wrapped during transit or storage.
In conclusion, choosing the right stretch wrap thickness is a critical step in the packaging process. With the right thickness, you can ensure that your items remain safe and secure throughout transport or storage.
By following these guidelines, you can rest assured knowing that your products will remain protected during transit or storage.
Furthermore, by selecting the appropriate thickness for each application, you can reduce any potential damages due to improper wrapping methods.
