拉伸膜 plays a crucial role in modern packaging and logistics, widely used for protecting and securing goods. However, users often encounter problems during actual use, such as poor film adhesion, tearing, and uneven wrapping. These issues can affect the safety of goods during transportation and overall efficiency. Understanding these common problems and their simple solutions will help users utilize stretch film more effectively, thereby improving packaging quality and transportation efficiency. This article will provide a detailed introduction to these problems and corresponding solutions.
I. Poor Stretch Hood Film Adhesion
Problem Description: When bundling goods, the film’s adhesion is insufficient, causing it to fail to adhere firmly to the surface of the goods, leading to slipping or detachment.
Solutions:
Choose the appropriate film type: Ensure that you use stretch film suitable for the specific goods. For example, for goods with smooth surfaces, choose a film with stronger adhesion.
Adjust the stretching force: When using the film, appropriately increasing the stretching force can improve the film’s adhesion, ensuring it tightly wraps around the goods.
Clean the goods’ surface: Ensure that the surface of the goods is clean, dry, and free of oil or dust, which can improve the film’s adhesion.
II. Film Tearing or Damage
Problem Description: During packaging or transportation, the stretch film is prone to tearing or damage, affecting its protective effect.
Solutions:
Check the film quality: Choose high-quality stretch film to ensure it has sufficient toughness and tear resistance.
Avoid contact with sharp objects: During loading and transportation, try to avoid contact between the film and sharp objects, especially when stacking heavy objects.
Proper stacking: Ensure that the goods are stacked stably to avoid damage to the film caused by the pressure of heavy objects.
III. Uneven Wrapping
Problem Description: When using 拉伸膜, uneven wrapping may occur, resulting in some areas being too loose or too tight.
Solutions:
Master the correct wrapping techniques: Use different wrapping methods according to the shape of the goods to ensure that the film evenly covers all surfaces.
Use film pallets: For irregularly shaped goods, using pallets or supports can help maintain stability and make the film wrapping more even. Setting Wrapping Standards: Establish specific operating standards, including the number of wrapping layers and stretching ratio, to ensure consistency in each packaging process.
IV. Deformation During Transportation
Problem Description: During transportation, goods wrapped with stretch film may deform due to vibration, affecting product safety.
Solutions:
Strengthen Fixing Measures: When bundling, ensure the film tension is appropriate, providing a tight wrap while also accommodating vibrations.
Use Auxiliary Materials: If necessary, use auxiliary materials such as foam pads and bubble wrap to enhance cargo protection and reduce the risk of deformation.
Choose Suitable Transportation Vehicles: Select appropriate transportation vehicles to ensure good stability and shock absorption during transportation.
V. Adhesion Between Films
Problem Description: When bundling multiple goods, the stretch film may stick together due to its inherent tackiness, making packaging difficult.
Solutions:
Use Isolation Materials: Place cardboard or other materials between different goods to prevent direct contact between the films.
Control Environmental Humidity: In humid environments, the film’s tackiness may increase; therefore, the working environment should be kept as dry as possible.
Adjust Film Thickness: Choose a film of appropriate thickness to reduce the risk of adhesion between different film layers.
Stretch hood system may encounter various problems during use, but with targeted solutions, users can effectively reduce the impact of these problems on packaging quality. Mastering correct operating techniques and choosing suitable materials can not only improve packaging safety but also increase overall transportation efficiency. We hope that the suggestions provided by Hsydpac will help you better apply stretch film in your daily work, ensuring the safety and integrity of your goods, and bringing greater convenience and efficiency to your logistics management.
