What are the temperature requirements for the storage of plastic stretch film

Plastic Stretch Film is an indispensable and important material in the modern packaging industry and is widely used to fix and protect various items. The stability of its performance and service life are affected by a variety of storage conditions, among which temperature control is particularly critical.

Effect of temperature on properties of plastic stretch film
Plastic stretch film is mainly made of thermoplastics such as polyethylene (PE) and polypropylene (PP), which exhibit different physical and chemical properties at different temperatures. Extreme temperature changes can significantly affect the mechanical properties, chemical stability and service life of the film.

Effect of high temperature
In high temperature environments, plastic stretch films tend to soften, resulting in a significant decrease in their tensile strength and tear strength. Not only does high temperature accelerate the aging process of the film, it can also make it brittle, prone to cracking and, in some cases, may release odors. Although anti-UV agents are added to some films to improve their protective properties, long-term exposure to high temperatures will still weaken their protective effects. Therefore, management of high-temperature environments is particularly important to ensure that the performance of plastic stretch films is not compromised.

Effect of low temperature
On the contrary, in a low temperature environment, the plastic stretch film will harden and lose its flexibility and ductility. Not only does this change reduce the tensile properties of the film, it can also lead to cracks or breaks during the packaging process. Low temperature environment will also affect the self-adhesiveness of the film, thereby affecting the packaging effect. Therefore, maintaining a suitable storage temperature is crucial to the performance of plastic stretch films.

Ideal storage temperature range
In order to ensure the best performance of plastic stretch film, it is recommended to control its storage temperature between 15℃ and 25℃. Within this temperature range, the film can maintain appropriate flexibility and mechanical strength, avoiding the adverse effects of high and low temperatures on its performance.

Practical recommendations for storage temperature control
Warehouse selection
When choosing a warehouse to store plastic stretch film, make sure it has a stable temperature control system to maintain the indoor temperature within the ideal range. In addition, the warehouse should be equipped with good ventilation facilities to reduce indoor humidity and prevent the film from getting damp to ensure that its performance is not affected.
temperature monitoring
Regular monitoring of the temperature of the storage environment is necessary to ensure that temperature fluctuations remain within allowable limits. For large warehouses, it is recommended to install temperature sensors and alarm systems to detect and handle temperature abnormalities in time to ensure that the storage conditions of plastic stretch films are always in the best condition.
Seasonal adjustment
In summer and winter, due to drastic changes in ambient temperature, special attention should be paid to adjusting the temperature of the storage environment. For example, in summer, the indoor temperature can be reduced by turning on air conditioners or fans, while in winter, heating equipment can be used to maintain the stability of the indoor temperature.
film protection
During storage, try to avoid direct exposure of the film to extreme high or low temperatures. Consider storing the film in a well-sealed packaging material to reduce the impact of temperature fluctuations on its performance. This measure will effectively extend the service life of the plastic stretch film and ensure its stable performance in practical applications.
