Technical requirements for environmental products

technical requirements for environmental products

technical requirements for certification of environmental labeling products

hjbz 12-2000

packaging products replace HJBZ 12-1997

the certified technical requirement for environmental labeling products

packaging produc in addition, PolyOne has specially hired sales and technical personnel with special engineering materials background in India ts

1 scope

this technical requirement It specifies the classification, definition, basic requirements, technical contents and inspection methods of environmental labeling products for packaging products. The technical requirements are applicable to substitute non degradable plastic film and bag packaging products (excluding disposable catering containers)

the composite film packaging products specified in the technical requirements are only applicable to paper plastic composite packaging products

PVC shall not be used in the production of all plastic components applicable to the technical requirements. 2 reference standard

the articles contained in the following standards are cited in the technical requirements, that is, the articles constituting the technical requirements, and have the same effect as the technical requirements

astm D 5338-92 Standard Test Method for aerobic biodegradation of plastics under controlled composting

gb 1040-92 test method for tensile properties of plastics

gb 9344-88 test method for exposure of plastic xenon lamp light source

gb 13022-91 test method for tensile properties of plastic films

when the above standards are revised, the latest version shall be used

3 product classification

products are divided into the following three categories according to plastic substitution: substitute packaging products: including completely substitute packaging products and composite film packaging products

easy to handle and recycle packaged products

degradable packaging products: biodegradable packaging products, photodegradable packaging products, photodegradable packaging products

4 definition

4.1 packaged products: the general name of containers, materials and auxiliary materials used according to certain technical methods to protect products, facilitate storage and promote sales during circulation

4.2 substitute packaging products: refer to packaging products made of plant fiber, animal fiber, starch, waste molasses, biodegradable synthetic polymer materials or water-soluble polymer materials with little or no plastic fiber

4.3 composite film packaging products: refers to packaging products made by combining two or more films in the product

4.4 Degradable Plastics: plastics whose chemical structure changes significantly under specific environmental conditions and whose material properties can be determined by standard test methods

approved by the State Environmental Protection Administration on March 10, 2000 to implement HJBZ 12-2000

4.5 biodegradable plastic packaging products on March 10, 2000: it maintains the same function as existing plastics in use, and can be decomposed into low molecular compounds for microorganisms in nature after use, and finally into inorganic materials such as water and carbon dioxide

4.6 photodegradable plastic packaging products: under the action of natural sunlight, the polymer as the main body of the plastic can break its molecular chain orderly, resulting in its fragmentation and decomposition

4.7 photo biodegradable packaging products: Human Detection Classification: it can be divided into the packaging products with improved measured activity. Due to the addition of photosensitizer or the promotion of biological oxidant, it can not only be affected by natural sunlight to cause chemical structure changes (molecular weight decline), but also reduce the strength of the material, resulting in cracking and fragmentation, but also moldy and rotten due to the action of microorganisms in nature. 4.8 easy to handle and recycle packaging products: refers to packaging products that will not produce any substances harmful to human health during the process of handling and recycling, and are easy to recycle 9 degradation rate: mass percentage of carbon element converted to CO2 and carbon content of sample under specified test conditions: D = wco2 × 12／44 × 100%

wco2 = GC2/GC, where: D - degradation rate ()

w differences between metal and non-metal tensile test settings CO2 - cumulative amount of 2 produced by degradation of unit weight sample (amount/)

gco2-co2 accumulation ()

gc - mass of carbon element in the sample ()

4.10 degradation tensile strength retention rate and degradation elongation at break retention rate: f=f2/f1

where: F - degradation tensile strength retention rate or 4. Penetration test degradation elongation at break retention rate;? F1 - tensile strength or elongation at break of the product before degradation test; F2- tensile strength or elongation at break of the product after the degradation test

5 basic requirements

5.1 the product quality shall meet the requirements of corresponding product quality standards

5.2 the hygienic indexes of products used for food packaging must meet the requirements of relevant hygienic standards

5.3 the pollutant discharge of enterprises must comply with the national or local pollutant discharge standards

6 technical content

6.1 requirements for substitute packaging products () completely substitute packaging products shall not contain plastic fibers

() plastic materials in composite film packaging products must meet the requirements of degradable products. 6.2 requirements for degradable packaging products (1) the degradation rate of biodegradable membrane packaging products shall be ≥ 1%

() the retention rate of degradation elongation at break of photodegradation type film packaging products shall be less than or equal to%

hjbz 12 － 2000

(3) degradation rate of photo biodegradable film packaging products ≥ package%, retention rate of degradation breaking elongation ≤ length%. 6.3 easy to handle and recycle packaging products? (1) The percentage of the quality of the recovered waste in the product raw materials to the product quality must be greater than argon%

(2) the recycling department in the product distribution area must undertake the product recycling. 7 inspection

7.1 the requirements of technical content 6.1 are verified by on-site inspection

7.2 the biodegradation of the product was tested by the method of st of Tilia amurensis Lindl

7.3 degradation tensile strength retention rate and degradation elongation at break were determined by the methods of "Tu Dao Yan" and "Chang 1040 -"? Or gb130-2

7.4 the requirements of 6.3 of technical content shall be completed through document review

additional notes:

this technical requirement is proposed by the science and Technology Standards Department of the State Environmental Protection Administration

the technical requirements shall be interpreted by the State Environmental Protection Administration
