5 Tips: Selecting The Right Stretch Film

by Nicolai Edgar Andersen

Stretch film, often referred to as plastic wrap or pallet wrap, is a crucial tool in the world of packaging and shipping. Whether you are a small business owner or a logistics professional, selecting the right stretch film is essential to ensure your products are securely bundled and protected during transit or storage. In this guide, we will walk you through five tips for selecting the perfect stretch film for your specific needs.

1. Determine Your Application

Before diving into the world of stretch film options, you should first determine the primary application. Stretch films are used for various purposes, and the type you choose will depend on your specific requirements. Here are some common applications:

Pallet Wrapping: If you need to secure and protect palletized loads, standard stretch film is often suitable. It provides stability and prevents items from shifting during transportation.
Packaging Individual Items: For bundling smaller items together or wrapping individual products, consider hand stretch film or mini-rolls for more control and convenience.
Heavy-Duty or Oddly Shaped Items: When dealing with heavy or irregularly shaped objects, consider heavy-duty stretch film or specialty films designed for unique requirements.

2. Gauge

Stretch films come in various thicknesses, typically measured in microns or gauges. The thickness affects the film's strength and stretchability. Stretch film is commonly available in gauges ranging from 0.5 to 3.0 mil. When choosing the appropriate film thickness, factors such as load type, weight, and height all play crucial roles. Here is a general guideline:

Lower Gauge (Thinner): Thinner films are more cost-effective and suitable for light to medium-weight loads. They offer less puncture resistance but are easier to stretch.
Higher Gauge (Thicker): Thicker films provide superior puncture resistance and are ideal for heavy or sharp-edged loads. They offer greater load stability but may require more effort to stretch.

Select a gauge that aligns with the weight and potential hazards associated with your products.

3. Consider Environmental Factors

If environmental concerns are a priority for your business, you may want to explore eco-friendly stretch film options. Some manufacturers offer films that are recyclable, biodegradable, or made from sustainable materials. These choices can align with your company's sustainability goals. In 2021, the world witnessed the debut of the first-ever compostable, industrial-strength stretch film.

In any scenario, making the right choice of film is vital when considering sustainable development. It contributes to reducing pollution, not only by preventing environmental littering but also by decreasing gas emissions through reduced film production.

4. Know Your Machinery

If you have machinery for stretch film application, make sure the film you choose is compatible with it. Different machines may require specific film types or sizes, so consult your equipment manual or supplier for guidance.

5. Test and Adjust

Lastly, do not hesitate to test different films and settings to find the ideal combination for your needs. Conduct load tests to ensure that your chosen film provides the necessary stability and protection.

In conclusion, selecting the proper stretch film involves an assessment of your application, the required thickness, environmental considerations, and machinery compatibility. By taking these factors into account, you can select the perfect stretch film to safeguard your products and streamline your packaging and shipping processes.
