Hand stretch film is a widely used solution for securing goods during transportation and storage. However, businesses often encounter a few common issues with its use. Understanding the root causes of these problems and knowing how to address them can ensure more efficient packaging and reduce material waste. PWP Stretch Film, a trusted brand in the industry, offers high-quality solutions designed to mitigate these challenges. Here are some common problems with hand stretch film, along with their solutions, which PWP Stretch Film effectively addresses:
Film Breakage or Tearing
Problem: One of the most common issues with stretch film is breakage or tearing, which can occur during the wrapping process. This problem is typically caused by using film with insufficient strength for the load being wrapped. Film breakage can also be due to rough handling, high tension, or incorrect gauge choice.
Causes:
- Incorrect Gauge: Using a film with too low of a gauge for heavy or irregularly shaped loads can lead to breakage of Common problems.
- Sharp Edges: Items with sharp edges can puncture or tear the film.
- Excessive Tension: Stretching the film too tightly can cause it to snap.
Solution:
- Select the Right Gauge: Choose a stretch film with an appropriate gauge for the load. For lighter loads, an 80-gauge film may suffice, while heavier or more irregular loads may require a 90-110 gauge film.
- Use Blown Stretch Film: Blown stretch film is often more resistant to punctures and tears compared to cast film, making it a good option for handling sharp-edged or heavier items.
- Proper Handling: Ensure the film is dispensed correctly, and avoid over-stretching or applying excessive tension during the wrapping process of Common problems.
Difficulty in Handling
Problem: Operators may experience fatigue or difficulty handling the stretch film, especially when wrapping large or heavy pallets. This can lead to inconsistent application and reduce packaging efficiency.
Causes:
- Heavy Rolls: Larger rolls of stretch film, especially machine stretch film, can be cumbersome and difficult to manage manually.
- Low-quality Film: Poorly made or flimsy stretch films can be harder to apply, requiring more effort to achieve the same load retention of Common problems.
Solution:
- Pre-Stretched Films: Pre-stretched films are a great solution for reducing operator fatigue. These films are already stretched during manufacturing, which means less effort is required to apply them. They also offer consistent performance and help reduce material waste.
- Use a Film Dispenser: Hand stretch film dispensers can help operators apply film with more ease and precision. These devices provide better grip and control, reducing fatigue and improving wrapping consistency.
- Smaller Rolls: If your business does not require wrapping large pallets, consider opting for smaller rolls or narrower widths. They are easier to manage and can be more cost-effective for smaller operations.
Incorrect Stretch Ratio
Problem: An incorrect stretch ratio can lead to inefficiency in the wrapping process. If the stretch ratio is too low, more material will be used to secure a load than necessary, leading to wasted film. On the other hand, if the ratio is too high, the film may not provide adequate load retention, making the packaging less secure of Common problems.
Causes:
- Wrong Film Choice: Choosing a stretch film with an inappropriate stretch ratio for the product being wrapped can cause inefficiency. Films with a high stretch ratio (e.g., 250-300%) may be used for lighter loads, while heavier products require films with a lower stretch ratio.
- Inconsistent Application: If operators stretch the film too much or too little, it can affect the final load containment, leading to under-stretching or over-stretching.
Solution:
- Select the Right Stretch Ratio: The key to choosing the right stretch ratio is to consider the type of product being wrapped. For heavy-duty items or irregular shapes, a lower stretch ratio (150-200%) may be more suitable, as it offers greater control and better containment. For lighter loads, a higher stretch ratio (up to 300%) can maximize efficiency and reduce material use.
- Training for Operators: Proper training on how to handle the film and achieve the optimal stretch is essential. Ensure that operators are familiar with the ideal stretch ratio for the products they are wrapping to avoid excess material use or under-secured loads.
Environmental Concerns and Waste
Problem: Environmental impact and film waste are growing concerns in industries that use large amounts of stretch film. The non-biodegradable nature of plastic stretch films, as well as overuse of material, can contribute to environmental pollution and increase operational costs.
Causes:
- Excessive Material Use: Improper stretch ratios or film application techniques can result in overuse of stretch film.
- Non-Eco-friendly Film Options: Many stretch films are made from petroleum-based plastics, which are not biodegradable.
Solution:
- Eco-friendly Options: Look for suppliers that offer biodegradable stretch film or recycled films. Some VCI stretch film are made from recycled materials, making them an eco-friendly choice for businesses that need corrosion protection without compromising sustainability.
- Reduce Waste: Opt for films with higher stretch ratios to reduce the amount of material used per load. Pre-stretched films are also more efficient, as they provide maximum coverage with less material of Common problems.
- Film Optimization: Invest in stretch film dispensers that allow precise film application to minimize waste. Additionally, reevaluate your wrapping process to ensure you’re using the right amount of film for each type of load.
