YBB
NATIONAL STANDARD OF THE
PEOPLE’S REPUBLIC OF CHINA
LDPE Films and Pouches for Pharmaceutical Packaging
LDPE Films and Pouches for Pharmaceutical Packaging
This Standard is applicable to pharmaceutical films produced by casting and blowing
methods with low-density polyethylene resin (LDPE) as the main raw material, and
pouches made by heat sealing the films. This product is applicable to the packaging of
non-sterile solid active pharmaceutical ingredient.
[Appearance] Take an appropriate amount of this product and look directly at it in a
bright place with natural light. The surface shall be smooth, uniform in color, and free
of perforations, foreign objects, odors, and adhesions. The heat-sealed part of the
pouches shall be smooth and free of false seals.
[Identification] * (1) Infrared spectroscopy: Take an appropriate amount of this
product and measure it according to the fourth method of infrared spectroscopy
determination method for packaging materials (YBB00262004-2015). It shall be
basically consistent with the reference spectrum.
(2) Density Take about 2g of this product; use absolute ethanol as the immersion
solution; and measure it according to the density measurement method
(YBB00132003-015). The density of this product should be 0.910~0.935 g/cm3.
[Barrier performance] Water vapor transmission rate: Take an appropriate amount
of this product; and measure it according to the first method experimental condition B
of the water vapor transmission rate measurement method (YBB00092003-2015), and
it shall not exceed 15g/ (m2•24 h).
Oxygen gas transmission rate: Take an appropriate amount of this product and
measure it according to the first or second method of the gas transmission rate
measurement method (YBB00082003-2015), and it shall not exceed 4000cm3/
(m2•24h•0.1MPa).
[Mechanical properties] Tensile strength: Take an appropriate amount of this
product; and measure it according to the tensile property determination method
(YBB00112003-2015). The test speed (no-load): 300mm/min±30mm/min, and the
specimen is Type-I. The average longitudinal and transverse tensile strength shall be
no less than 10MPa.
Elongation at break: Take an appropriate amount of this product; and measure it
according to the tensile property determination method (YBB00112003-2015). The test
speed (no-load) is 300mm/min±30mm/min, and the specimen is Type-I. For films with
a thickness less than or equal to 0.05mm, the average longitudinal and transverse
elongation at break shall be no less than 130%; for films with a thickness greater than
