Stretch film is an essential material in packaging, used to securely wrap products, protect them from damage, and optimize storage and transportation space. However, despite seeming simple to use, there are several common mistakes that can compromise its effectiveness, increasing costs and risks.
Using stretch film incorrectly can not only damage your products but also generate waste, impacting your operation’s efficiency. In this article, we’ll cover the 5 most common mistakes when using stretch film and how to avoid them to ensure that your packaging is optimal and efficient.
Error #1: Using the Incorrect Thickness for the Load
The Mistake:
One of the most common mistakes is choosing the wrong thickness of stretch film. If you select a material that is too thin for heavy products or too thick for light ones, you may not be fully utilizing its potential, or even generating unnecessary waste.
How to Avoid It:
The thickness of the stretch film should be chosen based on the weight and characteristics of the products being packed. For lightweight or small products, a thinner film (12 to 15 microns) is sufficient. However, for heavier or irregularly shaped products, it is recommended to use thicker films (20 to 25 microns). This not only ensures adequate protection but also reduces the possibility of breakage during transport.
Error #2: Incorrect Application Leading to Waste
The Mistake:
How stretch film is applied is crucial. If products aren’t wrapped efficiently, there may be excess material, which not only increases costs but can also affect the stability of the load. Too much film can lead to folds or bubbles that compromise safety.
How to Avoid It:
Make sure to wrap the products efficiently by stretching the film to the maximum without breaking it. The application should be even, covering tightly without overdoing it. If you’re using an automatic packaging machine, adjust the film’s tension correctly to avoid excess wrapping.
Additionally, apply the film in a “figure 8” or “X” pattern around the load to provide greater stability. This helps keep the product in place and prevents movement during transport.
Error #3: Not Considering Transportation Conditions
The Mistake:
Storage and transportation conditions, such as temperature, humidity, or exposure to sunlight, are key factors when choosing the type of stretch film. If these conditions are not considered, the film may not provide the appropriate protection.
How to Avoid It:
Before choosing the type of stretch film, assess the conditions to which your products will be exposed. If products are going to be stored or transported outdoors or in environments with extreme humidity or heat, select a film with special features, such as UV resistance or high durability against moisture.
For warm or outdoor climates, choose films with higher resistance or even anti-UV films that protect both the product and the packaging material.
Error #4: Choosing Low-Quality Stretch Film
The Mistake:
One of the most detrimental errors is selecting low-quality stretch film in an effort to reduce costs. Low-quality film can tear easily, which not only puts the safety of your products at risk but can also increase operational expenses due to potential damages.
How to Avoid It:
Always invest in high-quality stretch film that offers the necessary resistance and elasticity to ensure the safety of your products. Look for products that have the necessary certifications and guarantee durability. Check the manufacturer’s specifications, especially regarding tensile strength and elasticity, two key features that ensure proper protection.
Don’t forget to review other customers’ feedback and ratings to ensure the product meets your required standards.
Error #5: Not Using the Right Type (Manual vs. Automatic)
The Mistake:
Another common mistake is not choosing the appropriate type of stretch film based on your company’s packaging process. Manual stretch films are perfect for small volumes, but if you use an automatic machine for packaging and don’t choose the correct film type, you may encounter issues like tears or poor film fit.
How to Avoid It:
Manual Stretch Film: Ideal for small operations or products that don’t require high-volume packaging. It’s used by hand and is suitable for small loads.
Automatic Stretch Film: Perfect for large volumes and faster, more uniform packaging. This type of film is used with packaging machines, ensuring the application is precise and efficient.
Ensure that the film you choose is compatible with your system. If you work with an automatic machine, select a film designed to work with it, as packaging machines require materials with specific characteristics, such as greater elasticity and puncture resistance.
Stretch film is a fundamental tool in product packaging, but its effectiveness depends on how it is used. Avoiding these 5 common mistakes can improve the efficiency of your operation, reduce waste, and, most importantly, ensure proper protection of your products during transportation and storage.
By selecting the right type of film, applying it correctly, and considering the conditions in which it will be used, you will not only improve the safety of your products but also optimize your operational costs. Don’t underestimate the power of stretch film when used correctly!
