While temperature plays a more significant role in affecting the barrier properties of BOPP film, humidity still warrants consideration. In a warehouse environment, particularly one with elevated humidity levels, there is a greater likelihood of moisture absorption by the packaged products.
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.
BOPP Glossy Thermal Lamination Film is a thermoplastic film with polypropylene as the base material and made using special processes and formulas with high transparency, high gloss, high strength, high breathability and high durability. It is usually used for packaging, printing, Composite and other fields.
3D Color Thermal Lamination Film is a special thermoplastic coating material widely used in printing, packaging, advertising, decoration and other fields. It has the following advantages:
Determining the precise shelf life of BOPP films proves challenging, given that their degradation is contingent upon various conditions:
The most commonly asked question regarding plastic packaging films pertains to their expiration date. It is widely acknowledged that plastic possesses a significantly longer shelf life compared to other packaging materials like paper.
