Technical requirements for environmental labeling products of packaging products

In order to implement the "Environmental Protection Law of the People's Republic of China" and the "Law of the People's Republic of China on Energy Conservation", reduce the impact of packaging products on the environment and human health during production and use, improve the quality of the environment, solve the problem of white pollution, and promote the production of This standard is formulated using degradable or recyclable packaging products.

This standard partially changes the technical contents of "Technical Requirements Packaging Products for Environmental Labeling Products" (HJBZ12-2000) and has undergone a full editorial revision.
This standard is compared with the "Technical Requirements Packaging Products of Environmental Labeling Products" (HJBZ12-2000). The main changes are as follows:
-- Added the GB/T16288 plastic packaging product recycling mark in the normative reference documents;
In the classification, the packaging products that are in direct contact with foods, and the classification forms of packaging products that are not in direct contact with foods are added;
--Technical content adds requirements for materials used in packaging products that come into direct contact with food;
--Technical content has increased the requirements for product labels;
-- The technical content adds requirements for product storage and transportation processes.
This standard is a recommended standard and is applicable to the certification of China's environmental labeling products.
This standard was proposed by the Science and Technology Department of the State Environmental Protection Administration.
This standard is drafted by the State Environmental Protection Administration Environmental Development Center.
This standard was approved by the State Environmental Protection Administration on November 22, 2005.
This standard shall be implemented as of January 1, 2006, and shall replace the “Technical Requirements Packaging Products for Environmental Labeling Products” (HJBZ12-2000) from the date of implementation.
This standard is interpreted by the State Environmental Protection Administration.
The previous versions of the standard replaced by this standard are: HJBZ12-1997, HJBZ12-2000

First, the scope

This standard specifies the classification, definition, basic requirements, technical content, and inspection methods for environmental labeling products of packaging products.
This standard applies to replace non-degradable plastic film, bags and boxes of packaging products (except disposable dining containers).
The composite film packaging products in this standard classification are only applicable to paper-plastic composite packaging products.

Second, normative references

The clauses in the following documents have been adopted as references to this standard. For dated references, subsequent amendments (not including errata content) or revisions do not apply to this standard. However, parties that have reached an agreement based on this standard are encouraged to study whether the latest versions of these documents can be used. . For undated references, the latest version is applicable to this standard.

Third, product classification

Products are divided into two categories according to their use: packaging products that are in direct contact with food, and packaging products that are not in contact with food.
Products are divided into the following three categories according to plastic alternatives:
(1) Alternative packaging products: It includes completely substituted packaging products and composite film packaging products.
(2) Easy to handle and recycle packaging products.
(3) Degradable packaging products: biodegradable packaging products, photodegradable packaging products, and photo-biodegradable packaging products.

IV. Terms and Definitions

The following terms and definitions apply to this standard.
4.1 Packaging Products: The general term for containers, materials, and auxiliary materials used to protect products, facilitate storage, and promote sales according to certain technical methods during the circulation process.
4.2 Alternative packaging products: The use of plant fibers, animal fibers, and the use of starch, molasses, and synthetic biopolymers or water-soluble polymeric materials with little or no use of any plastic fibers. Packaging products.
4.3 composite film packaging products: refers to the product will be two or more films made of composite packaging products.
4.4 Degradable Plastics: Plastics whose chemical structure changes significantly under specific environmental conditions and whose physical properties can be determined using standard test methods.

4.5 biodegradable plastic packaging products: In use to maintain the same function with the existing plastic, after use can be broken down into low-molecular compounds for the existence of microorganisms in nature, and eventually decomposed into inorganic materials such as water and carbon dioxide polymer materials.
4.6 Photodegradable plastic packaging products: Under the action of natural sunlight, the polymer that is the main part of the plastic can be broken through the molecular chain, causing it to break and break down.
4.7 Photo-biodegradable packaging products: Synthetic polymer materials, due to the addition of photosensitizers or the promotion of biological oxidants, can cause changes in chemical structure (decrease in molecular weight) due to natural sunlight, decrease in material strength, and cracks. , broken, and can be caused by the role of microorganisms in the natural moldy, rotten packaging products.
4.8 Easy to process and recycle packaging products: refers to the packaging products that will not produce any substances that are harmful to human health during the processing and recycling process, and are easy to recycle and reuse.
4.9 Degradation rate: the mass percentage of the carbon element converted to C02 and the carbon content of the sample under the specified test conditions:
D=WCO2×12/44×100%
WCO2=GCO2/GC
In the formula: D--degradation rate (%);
W C O 2 CO 2 accumulation (g/g) due to degradation of a unit weight sample;
GCO2 - CO2 accumulation (R);
GC - mass of carbon in the sample (g).
4.10 Decomposition tensile strength retention or degradation elongation at break retention:
F=F2/F1
In the formula: retention of F-degradation tensile strength or retention of degradation elongation at break;
F1 - tensile strength or elongation at break of the product prior to degradation testing;
F2- The tensile strength or elongation at break of the product after the degradation test.

V. Basic requirements

5.1 The product quality should meet the requirements of the corresponding product quality standards.
5.2 The hygienic indicators of packaging products that are in direct contact with food should meet the requirements of relevant hygienic standards.
5.3 The emission of pollutants from the production enterprises shall meet the requirements of national or local pollutant discharge standards.
