Temperature has a significant impact on the shelf life of BOPP film, particularly in terms of its barrier properties such as water vapor transmission rate (WVTR) and oxygen transmission rate (OTR). Elevated temperatures lead to an increase in both WVTR and OTR for BOPP film. Consequently, the film's ability to shield the packaged product from moisture and oxygen is compromised.
As moisture and atmospheric oxygen infiltrate the packaged items, food products are subject to accelerated degradation. This renders the film ineffective in preserving the quality of the contents. To ensure the prolonged effectiveness of your BOPP film, it is crucial to maintain warehouse temperatures below 35°C.
In the event that temperatures exceed this threshold due to seasonal fluctuations or day-night variations, physical alterations may occur in the flexible packaging film. This can result in issues such as bagginess and slack edges.
