PVC is a mixed bag for bag material suitability. It offers durability and moisture resistance but poses significant environmental and health concerns.

PVC (polyvinyl chloride) is widely used in bags due to its lightweight nature, resistance to moisture and chemicals, and low cost. Studies show PVC bags can last 10–20 years under ideal conditions, outperforming alternatives like cotton or paper in longevity. However, PVC’s environmental impact is severe. The EPA estimates PVC accounts for 6% of global plastic waste, with only 25% recycled due to technical challenges. Incinerating PVC releases toxic dioxins, linked to cancer and reproductive issues. A 2021 study in Science found PVC contributes 10% of microplastic pollution from packaging. Additionally, producing PVC generates 10x more greenhouse gases than biodegradable alternatives. While PVC bags reduce single-use waste compared to alternatives like plastic films, their long-term persistence in landfills and oceans exacerbates ecological damage. The EU restricts PVC in food packaging due to leaching risks, while the U.S. EPA’s 2023 guidelines advise minimizing PVC use. Alternatives like HDPE (high-density polyethylene) or compostable materials offer better sustainability profiles. In conclusion, PVC is functional but environmentally detrimental, making it a poor choice for long-term bag solutions despite short-term convenience.
