Overcoming the transverse strength loss of Uniaxially stretched PLA films: The role of rigid amorphous fraction in achieving high performance

Key Points

• Transverse strength improves significantly with rigid amorphous fraction integration, enhancing overall performance.
• Introducing rigid amorphous fractions can reduce strength loss, marking a positive change in material properties.
• Observational analysis of PLA films reveals key interactions between structural components and strength.
• These insights may drive advances in materials engineering for better applications of PLA films.
