T/SGX 013-2022 Special material for poly(butylene adipate terephthalate)/polylactic acid film
Abstract
Scope: This document specifies the terms and definitions, product marking, requirements, test methods, inspection rules, labeling, packaging, transportation, and storage for polybutylene terephthalate-butylene adipate (PBAT) and polylactic acid (PLA) blended modified film special materials. This document applies to film special materials made from polybutylene terephthalate-butylene adipate and polylactic acid as the main raw materials, with the addition of corresponding additives, and obtained through melt blending modification. Main technical content: Serial number Item/Unit Indicators Requirements PLA nominal content (%) ≤ 10 10–20 (inclusive) 20–30 (inclusive) 30–40 (inclusive) > 40 Density/ (g/cm3) 1.25 ± 0.05 Melt flow rate (MFR)/ (g/10 min) X < 5 X ± 15 X ≤ 10 X ± 1.5 X ≥ 10 Ash content/ % ≤ 54 Water content/ % ≤ 0.15 Tensile strength/ MPa > 15 > 20 6 Breaking tensile strain/ % ≥ 500 ≥ 400 ≥ 300 ≥ 150 ≥ 50 Note: X is the melt flow index nominal value of the model product.
