Proper storage conditions for plastic raw materials are crucial, as inappropriate conditions can affect their quality and even render the products ineffective. Here are the main storage requirements for plastic raw materials:

1. Temperature: For most plastics, storage temperatures should be between 15-25°C, avoiding temperatures higher than 30°C or lower than 0°C. It is crucial to prevent sudden changes in temperature during storage, and temperature-stable air conditioning or heating equipment should be used for regulation.

2. Humidity: Plastics raw materials have stringent humidity requirements as well, typically needing a relative humidity between 50%-60%. Excessive humidity can lead to increased moisture in the plastic, accelerated chemical changes, and faster aging; conversely, low humidity can potentially cause scratching and brittleness.

3. Ventilation: When storing plastic raw materials, it is crucial to ensure proper ventilation to prevent moisture and contamination. Therefore, the storage room should maintain a dry, well-ventilated environment with no odors and dust.

4. Lighting: Certain plastics are particularly sensitive to UV rays, and storage in areas prone to ultraviolet exposure can lead to color change and surface cracking. If exposure to sunlight is unavoidable, measures such as "sunshade" or diffused light should be taken to mitigate UV damage.

When storing plastic raw materials, the following points should be noted:

Storage Time: Prolonged storage of plastic raw materials can lead to a decrease in material properties and is prone to chemical reactions with the surrounding environment. Therefore, it should be stored according to the production date, and the storage period should be calculated based on the manufacturer's instructions.

Inventory Management: Store plastic raw materials in batches, mix them evenly with machinery, and conduct random inspections. Also, pay attention to safety measures such as warehouse weight, fire prevention, and theft prevention.

3. Environmental Requirements: Plastic raw materials must comply with environmental regulations during storage and should not be disposed of arbitrarily. Additionally, qualified protective materials and storage equipment should be chosen to prevent environmental pollution and impact.
