Insufficient CO₂ barrier of PLA carbonated beverage bottles
ظاهرة المشكلة
The CO₂ permeability of PLA bottles is high, and the gas loss of carbonated beverages is fast.
تحليل الأسباب
The barrier properties of PLA to CO₂ and O₂ are both inferior to PET, with high gas permeability.
الحل
Use PLA composite barrier layers; nano fillers increase the path tortuosity.
الخلاصة الأساسية
The barrier property of PLA is a technical obstacle to beverage bottle applications.
