What are the storage environment requirements for PET cups

PET (polyethylene terephthalate) is a widely used thermoplastic. It must follow strict environmental requirements during manufacturing and storage to ensure the quality and safety of the finished product. PET Cups are widely used in the food and beverage industry due to their excellent transparency, impact resistance and good processing properties. In order to ensure its performance during use, factors such as temperature, humidity, light and pressure in the storage environment must be controlled.

In terms of temperature, it is recommended to store PET Cups in a room temperature environment of 15℃ to 25℃. Too high or too low temperature may cause changes in the physical and chemical properties of the material and affect its use effect. Therefore, it is crucial to choose a warehouse with stable temperature and good ventilation.

Humidity management should not be ignored either. Due to the hygroscopicity of PET materials, excessive humidity will lead to excessive absorption of moisture, which will affect the performance of the material and may even cause mildew. Therefore, it is crucial to keep the storage environment dry. Using dehumidification equipment and ensuring good ventilation are effective means to control humidity.

In terms of light, long-term direct sunlight will damage PET Cups, especially ultraviolet rays will accelerate the aging of the material, causing color fading and decreased transparency. Therefore, it is recommended to take shading measures in the storage area to avoid direct exposure to sunlight and reduce the use of strong light sources to reduce the impact of light on the product.

Pressure control is also an important aspect during storage. Excessive pressure or extrusion of heavy objects may cause deformation of PET materials, affecting their appearance and performance. To this end, PET Cups should be placed stably on sturdy shelves, avoid stacking too high, and be handled and transported with care to prevent damage.

Finally, care should be taken to avoid contact with harmful chemicals and keep the storage environment clean. Contact with harmful substances such as lubricants and chemicals may cause contamination or corrosion of PET Cups, thereby affecting their safety and use effect. Therefore, ensuring the cleanliness and safety of the storage area is an important measure to maintain the quality of PET Cups.
