Introduction
Interpretation of the National Standard of the People's Republic of China GB/T 33897—2017
1. Background of Standard Formulation and Analysis of Technological Evolution
Biopyester, especially polyhydroxyalkanoate (PHA), as an environmentally friendly material, has received extensive attention in recent years. The formulation of GB/T 33897—2017 aims to regulate the quality and performance of PHB blown film and promote its application in packaging, agriculture and other fields.
2. Comparative analysis of standard frameworks
| Dimensions | Standard requirements | Technical indicators |
|---|---|---|
| Product requirements | Product specifications, sensory requirements, physical and mechanical properties and biodegradability of the film | Thickness deviation, width deviation, tensile strength, biodegradability ≥ 60% |
| Test methods | References to GB/T 1037, GB/T 1040.1 and other standards | Cup method for measuring water vapor permeability, differential pressure method for measuring gas permeability |
| Inspection rules | Classification of factory inspection and type inspection | Appearance, thickness and width are mandatory inspection items |
Explanation of professional terms
Biodegradation rate: The degradation ability of materials in the natural environment, this standard requires ≥60%.
Polyhydroxyalkanoate (PHA): A bio-based material with good degradability and environmental protection.
Implementation suggestions
1. Production enterprises
- Optimize the ratio of raw materials to ensure that the biodegradation rate meets the requirements
- Establish a strict quality inspection system, focusing on monitoring thickness and width deviations
2. Users
- Select film products that meet the standards to ensure environmental protection performance
- Establish a long-term cooperation mechanism with suppliers to ensure product quality
