How to store PLA non woven?

by chad•

PLA non woven fabric, derived from polylactic acid, is an eco – friendly alternative to traditional non – woven materials. As a supplier of PLA non woven, I understand the importance of proper storage to maintain its quality and performance. In this blog, I will share some essential tips on how to store PLA non woven effectively. PLA Non Woven

Understanding the Characteristics of PLA Non Woven

Before delving into storage methods, it’s crucial to understand the properties of PLA non woven. PLA is a biodegradable polymer made from renewable resources such as corn starch or sugarcane. PLA non woven has several advantages, including good tensile strength, softness, and breathability. However, it is also sensitive to certain environmental factors, such as temperature, humidity, and light.

Temperature Considerations

One of the most critical factors in storing PLA non woven is temperature. PLA has a relatively low melting point, typically around 150 – 160°C. High temperatures can cause the material to deform, lose its shape, or even melt. Therefore, it is essential to store PLA non woven in a cool environment.

  • Optimal Temperature Range: The ideal temperature for storing PLA non woven is between 10 – 25°C. This range helps to maintain the material’s physical properties and prevent thermal degradation.
  • Avoiding Extreme Temperatures: Avoid storing PLA non woven in areas exposed to direct sunlight or near heat sources such as radiators, heaters, or ovens. In hot climates, it may be necessary to use air – conditioning or refrigeration to keep the storage area within the optimal temperature range.

Humidity Control

Humidity can also have a significant impact on the quality of PLA non woven. Excessive moisture can cause the material to absorb water, leading to swelling, mold growth, and a decrease in strength. On the other hand, extremely low humidity can make the material brittle.

  • Recommended Humidity Level: The recommended humidity level for storing PLA non woven is between 30 – 60%. This range helps to prevent moisture absorption and maintain the material’s flexibility.
  • Humidity Control Measures: To control humidity, you can use dehumidifiers in areas with high humidity or humidifiers in dry environments. Additionally, storing PLA non woven in sealed containers or bags can help to protect it from moisture.

Protection from Light

PLA non woven is sensitive to ultraviolet (UV) light, which can cause the material to degrade and lose its color and strength over time. Therefore, it is important to store PLA non woven in a dark or low – light environment.

  • Storage in Dark Areas: Store PLA non woven in opaque containers or in areas away from direct sunlight. If possible, use blackout curtains or blinds to block out UV light in the storage area.
  • Avoiding Fluorescent Lights: Fluorescent lights can also emit UV radiation, so it is best to use incandescent or LED lights in the storage area.

Proper Packaging

Proper packaging is essential for protecting PLA non woven during storage. The right packaging can prevent damage from physical contact, moisture, and light.

  • Sealed Bags or Containers: Use sealed plastic bags or containers to store PLA non woven. This helps to keep the material clean and dry and protects it from dust and debris.
  • Labeling: Label the packaging with information such as the type of PLA non woven, date of production, and any special handling instructions. This makes it easier to identify and manage the inventory.

Stacking and Handling

When storing PLA non woven, proper stacking and handling are important to prevent damage.

  • Stacking: Stack the rolls or sheets of PLA non woven in a stable and organized manner. Avoid over – stacking, as this can cause the material to deform or become damaged.
  • Handling: When handling PLA non woven, use clean and dry hands or gloves to prevent contamination. Avoid dragging or pulling the material, as this can cause tears or wrinkles.

Regular Inspection

Regular inspection of stored PLA non woven is necessary to ensure its quality. Check for signs of damage, such as tears, holes, or discoloration. Also, monitor the temperature and humidity levels in the storage area to ensure they remain within the recommended ranges.

Storage for Different Forms of PLA Non Woven

PLA non woven comes in various forms, such as rolls, sheets, and finished products. The storage methods may vary slightly depending on the form.

  • Rolls: Rolls of PLA non woven should be stored horizontally to prevent deformation. Place them on a flat surface or use a storage rack designed for rolls.
  • Sheets: Sheets of PLA non woven can be stacked neatly in a box or container. Make sure to separate the sheets with a layer of paper or plastic to prevent sticking.
  • Finished Products: Finished products made from PLA non woven, such as bags or wipes, should be stored in their original packaging or in a sealed container to protect them from damage.

Long – Term Storage

For long – term storage of PLA non woven, it is important to take extra precautions.

  • Vacuum Sealing: Vacuum sealing can be an effective way to store PLA non woven for an extended period. This helps to remove air and moisture, which can cause degradation.
  • Periodic Rotation: If you have a large inventory of PLA non woven, it is a good idea to rotate the stock periodically. This ensures that the older materials are used first and helps to prevent long – term storage issues.

Conclusion

Proper storage of PLA non woven is essential to maintain its quality and performance. By controlling temperature, humidity, and light, using proper packaging, and following good handling practices, you can ensure that your PLA non woven remains in excellent condition. As a supplier of PLA non woven, I am committed to providing high – quality products and sharing my knowledge to help you make the most of this eco – friendly material.
