Choosing the Right Plastic Stretch Film for Your Packaging Needs

Choosing the Right Plastic Stretch Film for Your Packaging Needs

When it comes to packaging products for transit, choosing the right plastic stretch film is crucial. A poorly chosen stretch film can result in damage to the product, higher costs due to excess material usage or even a negative impact on the environment. In this blog post, we will provide an overview of how to choose the right plastic stretch film for your packaging needs.

Types of Plastic Stretch Film

The most common types of plastic stretch film include cast stretch film, blown stretch film, and pre-stretched film. Cast stretch film is known for its clarity, quietness, and high tack, making it ideal for wrapping lightweight to medium-weight loads. Blown stretch film is tougher, thicker and more puncture-resistant than cast stretch film, making it ideal for heavier loads or products that have sharp edges or corners. Pre-stretched film, on the other hand, is a lighter gauge film that has been pre-stretched to reduce the amount of film needed to wrap a load, thus reducing material costs and environmental impact.

Factors to Consider When Choosing Plastic Stretch Film

Several factors must be considered when choosing plastic stretch film. The size and weight of the load, transit and storage conditions, pallet type and configuration, environmental impact, cost, and efficiency are some of the primary considerations. A well-informed decision is required to select the stretch film that best suits specific packaging needs. For example, heavier loads may require thicker stretch film, while lighter loads may be wrapped with thinner film. The environment in which the product will be stored and shipped also needs to be taken into consideration as certain types of stretch film may not perform well under extreme temperatures or humidity.

Testing Plastic Stretch Film

Testing the plastic stretch film before using it for packaging is essential to ensure its efficacy. Various types of tests can be performed to determine the quality of the stretch film. Some of the commonly performed tests include load retention, puncture resistance, and elongation. These tests are used to determine the strength, durability, and stretchability of the film.

Tips for Using Plastic Stretch Film

Using plastic stretch film effectively is key to ensuring that products are protected during transit. Here are some tips for using plastic stretch film to make the process easier and more efficient:

Start at the base of the load and work your way up: Starting at the base of the load and wrapping upwards will help ensure that the load is wrapped securely and that the film doesn’t slip during transit.

Make sure to overlap layers to ensure full coverage: Overlapping the layers of film will help ensure that the load is fully covered and protected.

Adjust the tension of the film based on the load weight: Adjusting the tension of the film based on the weight of the load will help ensure that the film is tight enough to secure the load, without causing damage to the product.

Use a dispenser to make wrapping easier and more efficient: Using a dispenser can make the wrapping process easier and more efficient, allowing for faster wrapping times and reduced material usage.

Common Mistakes to Avoid When Choosing Plastic Stretch Film

When choosing plastic stretch film, there are several common mistakes that companies should avoid:

Not considering the load weight and size when choosing the film: Choosing the wrong type of stretch film can result in damage to the product or increased material costs.

Failing to test the film before use: Testing the film before use is crucial to ensure that it will perform as expected.

Choosing a film solely based on cost without considering other factors: While cost is an important factor, it shouldn’t be the only consideration when choosing stretch film.

Not adjusting the tension of the film to match the load weight: Failing to adjust the tension of the film can result in either the load not being properly secured or the product being crushed by the film.

Case Studies

Here are some examples of companies that have successfully chosen the right plastic stretch film for their packaging needs:

Company A was experiencing damage to their products during transit due to the stretch film not providing enough support. After switching to a heavier gauge stretch film, they saw a significant decrease in product damage.

Company B was using a high-gauge stretch film for all of their products, resulting in excess material usage and higher costs. After evaluating their packaging needs, they switched to a pre-stretched film, reducing material usage and saving money.

Future of Plastic Stretch Film

The future of plastic stretch film is likely to include advancements in technology and the use of sustainable materials. One potential area of development is the use of nanotechnology, which could lead to stronger, thinner films that are more environmentally friendly. Additionally, there is an increasing demand for sustainable materials, and manufacturers are exploring ways to produce stretch film using materials such as biodegradable plastics and recycled materials.


Choosing the right plastic stretch film for packaging needs is crucial to ensure the safety of the product and minimize costs. By considering factors such as load weight, transit and storage conditions, and cost, companies can make an informed decision about which type of stretch film is best suited for their needs. Additionally, following best practices when using stretch film, avoiding common mistakes, and staying up-to-date on advancements in the industry can help companies optimize their packaging process and achieve better outcomes for their products.
