Introduction

Increasing the use of biomass resources in the manufacture of plastic products can effectively reduce global warming and the consumption of fossil resources.

Current plastic products consist of bio-based synthetic polymers, fossil-based synthetic polymers, natural polymers and additives (may include biological substrates)

料) Composition.

Bio-based plastics refer to plastics that contain all or part of materials of biological origin.

In this series of standards, the bio-based content of bio-based plastics only refers to the content of bio-based carbon, the content of bio-based synthetic polymers, or the content of bio-based synthetic polymers.

The content of bio-based substances.

1 Scope

This part of GB/T 39715 specifies the determination method for the bio-based content of bio-based synthetic polymers in plastic products. The student

The calculation method of the content of the material-based synthetic polymer is based on the quality of the bio-based synthetic polymer in the plastic product.

This section applies to plastic products, plastic materials, polymer resins, monomers or additives made from bio-based and/or fossil-based ingredients.

Knowing the bio-based content of plastic products helps to assess their environmental impact.

4 Principle

Biomass labeling used in plastic products is a feasible method to evaluate the development effectiveness of partially or completely bio-based synthetic polymers. Other

It also helps consumers understand and compare their relative contributions to environmental protection.

This section provides methods for measuring the content of bio-based synthetic polymers derived from biomass resources.

The content of bio-based synthetic polymers in plastic products can be based on the composition of the plastic (as described in the list of component mass fractions), and the corresponding
