Best Stretch Wrap for a Business:
To figure out what makes today’s excellent pallet wrap or stretch wrap, it’s helpful to study the development of this material, which has become ubiquitous in warehouses all over the globe. It was developed almost a century ago and was manufactured of PVC. In the 1950s, it had a huge international consumption. By the 1970s, a wrap with a 50% stretch had been developed, which was a significant scientific breakthrough at the era.
It was necessary to devise a fresh strategy. Low-density polyethene was the material used. Yes, it was more robust, but the negative this time was its lack of “stretchability” — this could only stretch 30 percent. LLDPE film (Linear low-density polythene) was developed after another revision in 1976, and it was introduced to the US market.
Stretch Wraps with a Twist:
Stretch wrap has evolved into the go-to protective packaging component for dependable and durable transportation of products by the late 1980s and early 1990s. Stretch wrap enabled the transportation of bigger pallets, resulting in more cost-effective deliveries.
Stretch wrap enabled the transportation of bigger pallets, resulting in more cost-effective deliveries. As a result, the race was on to create a wrap that could extend even longer, delivering even larger savings while maintaining the same level of dependability.
A single layer of film, known as a “mono” layer, was used to make the stretch wrap at the time. As a result, experimenting with added layers of film became the beginning point for the next stage of its growth.
With the addition of more layers, each layer developed its own distinct ‘signature’ in terms of the function it served. For example, a layer was created to gain higher stretch, another for stability, and still another one for cling — when these layers were merged, they created the very first stretch wrap that is being used nowadays. It increased the stretch of the 1970s version to 100%, and this was the beginning of additional testing that saw much more layers added, each with its own purpose, much like a recipe.
Types of Stretch Wrap:
There are two types of stretch wrap.
- Blown Stretch Film
- Cast Stretch Film
Blown stretch film and cast stretch film are the two primary forms of film distinguished by the production method.
Blown Stretch Film Characteristics:
The production technique of blown film extrusion lends itself to blown wrap has a number of appealing properties, including:
- Exceptionally robust and long-lasting.
- Excellent resilience to punctures
- Reduces the amount of scrap produced in the production process.
- Has a strong cling factor
Cast Stretch Film’s Characteristics:
Cast extruded stretch film has the following advantages:
- Exceptional clarity
- Aromas, dampness, and fumes are all held at bay by this remarkable barrier.
- Thickness is consistent all across
- The film thickness is unrestricted.
- A peaceful way to decompress
Nano Film & High-Performance Stretch Wrap (iWrap):
The method has been improved even further, and until recently, the most interesting breakthrough in stretch wrap was a product called Nano Film, which has been on the market for about 5 years. A four-layer film structure is used to create it. The film is divided and re-joined in order to increase the number of layers. This separating and re-joining process may be repeated indefinitely, but the main disadvantage is that it still only has the qualities of the four initial film layers, making it restricted by nature.
With the introduction of the iWrap, a next-generation high-performance stretch wrap, science has once again come to the rescue. This Intelligent Pallet Wrap features 11 layers of film that are all created directly from the extrusion head. As a result, unlike in the Nano film example, there is no need to divide and rejoin the film layers.
Each layer in iWrap has its own purpose and attribute. It truly is a best-in-class product, with the ability to program in stretch, cling, and tear resistance capabilities at the time of production to meet your unique demands and specifications.
Where Does Stretch Wrap Stand in the Future?
Plastic usage and disposal will continue to be a problem, and we should all be searching for methods to limit our consumption. iWrap is the thinnest and most stable film available. iWrap will continue to evolve to meet the demands of modern organizations, with a latest version with 500 percent stretch in the works. This is fantastic news for all supply chain users and end-users.
