3 Terms and definitions
3.1
Disposable paper straw for food contact
The disposable paper straw for food contact which is made from wood pulp
or other plant fibers as the main raw material, by processes such as bonding,
winding, drying and slitting after printing or without printing.

4806.1.
5 Raw material requirements
5.1 The raw materials used in disposable paper straws for food contact shall
not cause harm to human health.
5.2 The paper, oil, ink, adhesive used in disposable paper straws for food
contact shall meet the relevant requirements of the national food safety
standards.
5.3 Disposable paper straws for food contact, including additives used in
coating, shall meet the requirements of GB 9685 and related announcements.
5.4 Do not use or partially use recycled paper pulp to produce disposable paper
straws for food contact.
5.5 Do not use coated paper and cardboard such as polyethylene,
polypropylene or polyethylene terephthalate (PE, PP or PET) film to produce

Table 1 -- Sensory requirements
Item Requirements
Appearance
The outer wall is smooth; the cut is flat and free of burrs; there is no peeling, cracks or
grooves between layers; there is no defect such as dents or impurities
Printing a The pattern is clear; there is no misregistration and ink falling off.
the first acceptance number and the first rejection number, the second sample
of the sample size given by the plan shall be checked and accumulated in the
number of nonconforming products as found in the first sample and the second
sample. If the cumulative number of nonconforming products is less than or
equal to the second acceptance number, then the batch is determined to be
acceptable; if the cumulative number of nonconforming products is greater than
or equal to the second rejection number, then the batch is determined to be
unacceptable.
11 Judgment rules
11.1 Exit-factory inspection items
The exit-factory inspection items include the contents in Chapter 6 and Chapter
9.
11.2 Judgment of exit-factory inspection items
If the exit-factory inspection items comply with the requirements, the batch of
products is determined to be qualified. If more than one item does not meet the
requirements, the batch of products is determined to be unqualified. If there is
only one item that does not meet the requirements, double number of samples
shall be taken from the original batch for the reinspection of the nonconforming
items. If the results of the re-inspection meet the requirements, the batch of
products is determined to be qualified.
11.3 Type inspection items
Type inspection shall be carried out in the following situations, which shall
include all items of this standard:
a) When the new product is put into production;
b) When changing main raw and auxiliary materials or changing key
processes;
c) When the production is resumed after suspension for more than 3 months;
d) When there is a big difference between the exit-factory inspection result
and the last type inspection result;
e) When required by the national market supervision department.
11.4 Judgment of type inspection
When all the test items comply with the regulations, the batch of products is
determined to be qualified.

Test method
A.1 Migration test method
The migration test shall be carried out in accordance with the provisions of GB
31604.1 and GB 5009.156, unless there are special provisions in this standard.
A.2 Color migration test in artificial saliva
A.2.1 Preparation of artificial saliva
Accurately take 4.2 g of sodium bicarbonate, 0.5 g of sodium chloride, 0.2 g of
potassium carbonate, 0.03 g of sodium nitrite in a large beaker. Use purified
water to dissolve and dilute to about 900 mL. Add 1 mol/L sodium hydroxide
solution or 1 mol/L hydrochloric acid solution dropwise to adjust the pH to 9.0.
Transfer the solution into a 1 L volumetric flask. Use distilled water to dilute to
make its volume reach to the mark.
A.2.2 Preparation of impregnated paper straws and filter paper strips
Cut the paper straw into a size of 5 cm long; cut the filter paper into a size of
about 2 cm x 5 cm. Place the cut filter paper strips in artificial saliva and soak
for 1 min. Take it out to prepare for use.
A.2.3 Test color migration
Take the filter paper out of the artificial saliva. Lay the two saturated filter paper
strips in parallel on the glass plate to avoid wrinkles. Place two segments of
straws on them; keep the central axis aligned; keep the two ends are flush, see
the schematic diagram A.1 for the specific placement. Press another glass plate
on the paper straw; add a 1 kg weight or equivalent weight to the glass plate;
keep it at (23 ± 2) ...
