What are the temperature requirements for storing disposable crystal trays

Disposable crystal plates are widely used in catering, parties, events and other occasions due to their lightness, economy and beauty. However, to ensure their safety and effectiveness during use, storage conditions, especially temperature control, are particularly important.

Storage temperature requirements
Disposable crystal plates are mainly made of materials such as polystyrene (PS) or polypropylene (PP), which exhibit excellent physical properties within a specific temperature range. It is generally recommended to maintain the storage temperature between 10°C and 30°C. Within this range, the physical properties of the material remain stable, reducing the risk of deformation or damage. If the temperature of the storage environment is too high, the material of the crystal plate may soften, causing deformation, distortion or even cracking. In addition, excessively high temperatures may also cause the chemical composition of the material to decompose, thereby releasing harmful substances, which directly affects food safety. Therefore, during storage, companies should avoid placing disposable crystal plates in high temperature environments, such as areas with direct sunlight or near heat sources.

Effect of high temperature on material properties
In high temperature environments, the melting points of polystyrene and polypropylene materials are generally low, usually between 70°C and 100°C. When the temperature exceeds this range, the molecular structure of the material may change, resulting in a significant decrease in physical properties. For example, the strength and rigidity of the crystal plate will be weakened, and it is more likely to break during use. In addition, long-term exposure to high temperature environments may also cause aging of the material, which is manifested as color fading, surface roughness and other problems, which not only affects the appearance of the product, but may also affect its use effect.

Effect of low temperature on materials
Although the effect of low temperature on disposable crystal plates is relatively small, the brittleness of the material may increase under extreme low temperature conditions. Polystyrene may become more fragile in an environment below 0°C and easily break when it is hit or under pressure. Although low-temperature storage will not directly cause product deformation, special attention should be paid during use to prevent accidental breakage.

Effect of temperature fluctuations
Severe fluctuations in temperature will also have a negative impact on the quality of disposable crystal plates. When the temperature of the storage environment changes frequently, the material of the crystal plate may be affected by thermal expansion and contraction, resulting in the generation of tiny cracks. These cracks may expand during use and eventually lead to product damage. Therefore, maintaining a stable storage temperature is the key to ensuring the quality of disposable crystal plates.

Selection of storage environment
In order to effectively control the storage temperature, companies should choose a suitable storage environment. This includes using air conditioning or constant temperature equipment to maintain a suitable temperature range. The storage area should avoid direct sunlight, and it is best to choose a cool, well-ventilated place. In addition, regularly check the temperature and humidity of the storage environment to ensure that it meets the standard requirements. Through scientific and reasonable storage measures, companies can not only extend the service life of disposable crystal plates, but also ensure their safety and effectiveness during use, thereby providing customers with a higher quality product experience.
