This discrepancy can lead to overestimation of cellophane's compostability performance in practical applications.

Advancing cellophane's compostability standards also faces economic challenges. Developing new formulations or manufacturing processes to enhance compostability while maintaining product performance can be costly. This economic barrier may slow down industry-wide adoption of improved compostable cellophane products, particularly in competitive markets where price sensitivity is high.

Lastly, the lack of consumer awareness and proper disposal infrastructure presents a challenge in realizing the full potential of compostable cellophane. Even if improved standards are developed and met, the environmental benefits can only be fully realized if consumers correctly dispose of cellophane products in appropriate composting facilities. This highlights the need for comprehensive approaches that address not only technical standards but also education and infrastructure development.

The cellophane compostability standards market is in a growth phase, driven by increasing environmental concerns and regulatory pressures. The market size is expanding as more industries adopt sustainable packaging solutions.
