Due to the recent situation in the Middle East, the procurement of raw materials and the supply of products are beginning to be affected. There are increasing concerns about future supply uncertainties, even for petroleum-derived products such as polyethylene. In light of this situation, we propose biodegradable stretch film as one of the options for existing stretch films. Unlike petroleum-derived products, it has a supply chain that includes plant-based components, making it relatively less susceptible to the logistics and raw material risks currently being raised. In addition to environmental considerations, it can also be utilized as an alternative option to existing stretch films. *For more details, please download the PDF or feel free to contact us.*
