Compliance overview
Scope and applicability
This standard applies to the packaging of baled lint cotton and cotton linters. It specifically covers the technical requirements, packaging methods, marking, and testing methods for cotton bales. It is mandatory for all manufacturers and processors involved in the packaging of cotton products in China. The standard is not applicable to loose cotton or cotton textiles.
Technical requirements
The standard specifies the physical dimensions and weight tolerances for two types of cotton bales (Type I and Type II), including strict limits on height differences between the two ends of a bale. For packaging materials, it mandates the use of non-contaminating materials such as unbleached pure cotton cloth or specific plastic packaging bags. The plastic bags must feature breathable pores to prevent dust entry while avoiding residual film debris. For strapping materials, the standard outlines mechanical performance requirements for galvanized steel wire and polyester strapping bands. It specifically requires polyester bands to have defined joint overlapping lengths and surface markings indicating the manufacturer's trademark, name, and production date. Materials must not produce foreign fibers or contaminate the cotton. The standard also details the packaging methods, distinguishing between the strapping method (where compressed cotton is wrapped in cloth before strapping) and the bagging method (where the bag is applied after compression and strapping). It mandates that bales must not expose any cotton (except breathable pores) and must be free from packaging damage or contamination upon leaving the factory. Regarding marking requirements, it differentiates between batch-inspected and bale-inspected cotton. Marks must include the cotton origin, processing unit, quality identification, batch number, bale number, gross weight, and foreign fiber content code. For bale-inspected cotton, barcodes are mandatory and must be securely fixed to both ends of the bale.
Testing methods
The standard outlines various testing procedures to verify compliance. Dimensional inspections of cotton bales are conducted 24 hours post-packaging using calibrated measuring tools. Material tests include determining cotton cloth density and breaking force per GB/T 4668 and GB/T 3923.1. For plastic packaging films, tensile strength and elongation at break are tested according to GB/T 1040.3. Crucially, accelerated weathering tests using xenon arc and fluorescent UV lamps are mandated to evaluate the anti-aging properties of plastic films and polyester strapping bands. Mechanical properties of galvanized steel wire and polyester strapping, including joint breaking force and peeling force, are also rigorously evaluated.
FAQs
What products are regulated under GB 6975-2013?
This standard applies to the packaging of baled lint cotton and cotton linters. It covers the technical requirements, packaging methods, marking, and testing methods for both Type I and Type II cotton bales.
Are there any major updates from the previous version of GB 6975?
The 2013 version deletes the 200kg Type II bale, reclassifying the original Type III as the new Type II. It also adds basic manufacturing requirements for plastic packaging bags (including elongation and aging resistance), replaces "plastic strapping" with "polyester strapping for cotton packaging," and adds performance metrics for joint breaking force and peeling force.
How does GB 6975-2013 differ from international cotton packaging standards?
While the standard focuses specifically on the dimensional, material, and marking requirements for the Chinese cotton industry, it incorporates testing methodologies aligned with international ISO standards, such as ISO 527 (via GB/T 1040.3) for plastics and ISO 1421 (via GB/T 3923.1) for textile fabric tensile properties.
