General Requirement of Degradable Disposable
Tableware
1 Scope
This Part specifies the definitions and terms, classification, technical requirements, test
methods, inspection rules, and product packaging and marking, packaging,
transportation, and storage requirements for degradable disposable tableware.
This Part is applicable to the degradable disposable tableware made from various raw
materials such as resin, starch, plant fibre, etc., as defined in 3.3; and also, is
applicable to other degradable disposable tableware food contact layers covered or
coated with or compounded with biodegradable plastic films or sheets.
This Part is not applicable to paper tableware such as paper cups and paper bowls.

3.2 Disposable tableware
Utensils intended for meals or similar purposes, including disposable food boxes,
plates, dishes, knives, forks, spoons, chopsticks, bowls, cups, barrels, jars, pots, lids,
etc.; and disposable inner-lining tableware with external support; as well as includes
food packaging for dining or similar purposes. However, it does not include food
packaging materials that are not intended for meals or similar purposes, such as fresh
food trays, yogurt cups, jelly cups, etc.; and food packaging materials that are only
used for food preservation, display, storage, and sealing, such as biscuit backing, cake
boxes, etc.
3.3 Degradable disposable tableware
Disposable tableware (3.2) made of biodegradable (3.1) materials.
4 Classification
The degradable disposable tableware specified in this Part can be divided into heat-
resistant and heat-labile degradable disposable tableware according to the degree of
heat resistance during use.
5 Technical Requirements
5.1 Appearance
The appearance shall comply with the following requirements:
a) Normal colour;
b) There shall be no cracks and filling defects;
c) No oil, dust, mildew and other foreign matter on the surface;
d) The surface is flat and clean, with uniform texture, no scratches, no wrinkles, no
peeling or delamination, no cracks, no perforations;
e) Coloured tableware must not have obvious discoloration, fading, uneven colour
(except for decoration requirements), stains, etc.;
f) If the surface of the tableware is painted, there shall be no sagging, peeling,
cracking, blistering, etc. on the painted surface;
The half-folding test of the lid only has requirements for degradable disposable
tableware with one-piece lid and container; and there are no requirements for those
tableware that are two-piece lid and container, or lid-free, such as food boxes, bowls,
cups, plates, dishes, knives, forks, spoons, chopsticks, etc.
5.3.5 Heat resistance
5.3.5.1 Hot-water resistance
After the hot-water resistance test, it shall not be deformed, peeled, or wrinkled; and
the tableware with container function shall not be deformed, infiltrated or leaked.
The two tested samples shall be no obvious deformation, infiltration and leakage, either.
The hot-water resistance test only has requirements for degradable disposable
tableware that may contain hot vegetables, hot foods and hot drinks, such as boxes,
cups, bowls, etc.; it has no requirements for the degradable disposable tableware that
do not require heat-resistance, such as plates, dishes, knives, forks, spoons,
chopsticks, lids, etc.; it also has no requirements for the degradable disposable
tableware that are labelled heat-labile.
Degradable disposable tableware made of materials that are heat-labile, including
foamed and non-foamed tableware, shall be clearly marked with the highest heat-
resistant temperature. The hot-water resistance test shall be carried out according to
the marked temperature during the test. If there is no mark, it shall be uniformly tested
as the heat-resistant degradable disposable tableware.
5.3.5.2 Hot-oil resistance
After the hot-oil resistance test, it shall not be deformed, peeled, or wrinkled; and for
the tableware with container function, it shall not infiltrate or leak.
The two tested samples shall be no obvious deformation, infiltration and leakage, either.
The hot-oil resistance test only has requirements for degradable disposable tableware
that contains hot vegetables and hot foods, such as boxes and bowls, etc; it has no
requirements for the degradable disposable tableware that do not require hot-oil
resistance, such as plates, dishes, knives, forks, chopsticks, cups, etc.; it also has no
requirements for the degradable disposable tableware that are labelled heat-labile.
5.3.6 Water leakage
For degradable disposable tableware that have the function of containing liquids, such
as boxes, bowls, cups, etc., no water shall leak after the test.
Test two samples, and there must be no leakage.
The volatile solid content shall be ≥51%.
5.7 Degradability
The degradability shall meet the following requirements at the same time:
a) The relative biodegradation rate shall be ≥90%, and the biodegradation rate of
organic components with components ≥1% in the material shall be ≥60%.
b) If the degradable tableware is composed of a mixture or a composite of multiple
materials, the organic ingredients with a component content of < 1% shall also be
biodegradable, but proof of biodegradability may not be provided, and the total
amount of each component shall be < 5 %.
NOTE: The biodegradability of organic ingredients with a component content of < 1% can
provide corresponding product inspection reports or enterprise self-declaration.
5.8 Compostable degradability
5.8.1 Biodegradation rate
The biodegradation rate shall meet the following requirements at the same time: ...
