Plastic products, paper products, etc. play an important role in daily life, physical performance index can be used as a standard to measure the quality of products, in addition to traditional plastics, emerging biodegradable plastics are also widely concerned.

Biodegradable plastics refer to the degradation caused by microorganisms existing in nature, such as soil, sand, fresh water environment, seawater environment, specific conditions, such as composting conditions or anaerobic digestion conditions. And will eventually fully degrade to a plastic form of carbon dioxide (CO₂) or/methane (CH₄), water (H₂O), mineralized inorganic salts of the elements contained therein, and new biomass such as microbial dead bodies.

Food related products: Food Safety Law, Product Quality Law, interim Measures for Product Quality Supervision and Sampling Inspection management, Detailed rules for implementation of food related Product production License, etc

Mulching: administrative measures for agricultural mulching

Biodegradability and biodegradation products related testing:

Determination of the ultimate aerobic biodegradability of plastic materials under conctrolled composting conditions——Method by analysis of evolved cabon dioxide——Part 1：General method(GB 19277.1)

Determination of the ultimate aerobic biodegradability of plastic materials under controlled composting conditions——Method by analysis of evolved carbon dioxide—Part 2:Gravimetric measurement of carbon dioxide evolved in a laboratory-scale test(GB19277.2)

Degradability and identification requirements of biodegradable plastics and products（GB/T 41010)

Biodegradable plastic shopping bags（GB/T 38082)

Biodegradable drinking straws(GB/T 41008)

Starch-based biodegradable resin(GB/T 27868)

Starch-based plastic shopping bags

Biodegradable mulching film for agricultural uses(GB/T 35795)

Common physical performance testing：

Length/width/volume deviation, load-bearing performance, tensile performance, drop performance, sealing strength, heat resistance, cold resistance, impact strength of simply supported beams, melt flow rate, right-angle tearing load, water vapor permeability, oxygen permeability, artificial aging performance, etc
