Bio-based Artificial Leather for Bags
Bio-based Artificial Leather are more and more widely used for shoes, bags, garments , sofa, furniture and other products.
Our Bio-based leather are widely sold all over the world. It's one of our main production.
Here we would like to talk about the composition & Physico , Chemical Test Data of it for your reference.
1. Overview
This document summarizes the composition ratios, physical performance, and chemical / environmental test data for plant- and fruit-based bio-based artificial leather intended for bag and luggage applications. All data is aligned with current GB/T national standards and industry benchmarks, and can be used directly for product development, quality control, and customer technical communication.
Key advantage: Bio-based carbon content (XOC) ranges from 30% to 66%, some are even 100%, significantly reducing reliance on fossil-based resins while maintaining bag-grade mechanical performance.
