/GBPI Hosts Pivotal National Standard Revision Meeting for Packaging Composite Films and Bags
GBPI Hosts Pivotal National Standard Revision Meeting for Packaging Composite Films and Bags March 28,2025.

Guangzhou, China March 27, 2024 Guangzhou Biaoju Packaging Equipment Co., Ltd. (GBPI) successfully hosted the National Standard Revision Meeting for General Rules for Plastic Composite Films and Bags for Packaging, a critical initiative organized by SAC/TC48/SC1 (Subcommittee for Plastic Daily-Use Products under the National Technical Committee for Plastic Products). This high-profile event brought together over 50 experts, corporate representatives, and technical leaders from across China to refine and modernize the national standard GB/T 21302-2007, which has governed the industry for nearly two decades.  

 Revolutionizing an 18-Year-Old Standard  

The revision, mandated under Chinas 2024 Sixth Batch of Recommended National Standards (Plan No.: 20242730-T-607), responds to seismic shifts in packaging technology, safety requirements, and sustainability imperatives. Since the original standards implementation in 2007, the industry has undergone three transformative structural changes:  

1. Technological Leap: Innovations like co-extrusion composites, digital printing, high-barrier coatings, and solvent-free bonding have revolutionized production. Modified polyolefins and single-material structures now dominate, replacing traditional multi-layer designs.  

2. Enhanced Safety Protocols: Stricter limits on solvent residues and migrant substances, aligned with global food safety standards (e.g., EU and FDA regulations), demand advanced testing methodologies.  

3. Green Regulatory Pressure: Chinas dual-carbon goals and circular economy policies have accelerated adoption of eco-friendly materials and energy-efficient processes.  

Mr. Zhou, General Manager of GBPI Guangzhou, opened the meeting by emphasizing the urgency of aligning standards with these advancements: This revision isnt just about complianceits about leading the global packaging industry toward innovation and responsibility.”  

 Consensus-Driven Outcomes  

Under the leadership of Secretary-General Peng, delegates reached consensus on key revisions:  

- Material Innovation: Prioritizing mono-material structures to enhance recyclability and reduce carbon footprints.  

- Process Standards: Establishing benchmarks for emerging technologies like vacuum metallization and water-based adhesives.  

- Safety Thresholds: Lowering solvent residue limits to 3 mg/m² and adopting GC-MS (Gas Chromatography-Mass Spectrometry) as the primary testing method.  

- Sustainability Metrics: Introducing lifecycle assessment (LCA) criteria for composite films and promoting biodegradable alternatives.  

Industry leaders, including Jiangsu Caihua Packaging Group and Huangshan Novel Co., Ltd., underscored the economic implications. Standardization will eliminate low-cost, non-compliant competitors and foster high-value growth,noted a representative from Jiangsu Caihua.  

The Road Ahead for Chinas Packaging Industry  

The revised standard is expected to take effect in Q4 2025, with a 12-month transition period for industry compliance. Analysts predict it will:  

- Boost Export Competitiveness: Aligning with ISO and ASTM International standards to ease cross-border trade.  

- Drive R&D Investment: Over 60% of surveyed firms plan to increase budgets for green material development.  

- Accelerate Consolidation: SMEs lacking technical capacity may merge with larger players, raising industry concentration.  

GBPI Guangzhou, a key contributor to the revision, reaffirmed its commitment to supporting enterprises through advanced testing equipment and technical training. Were not just setting standardswere building ecosystems,said a GBPI spokesperson.  

 Global Implications  

As China produces over 40% of the worlds plastic packaging, this revision carries global significance. International observers, including the Sustainable Packaging Coalition, praised the focus on solvent-free processes and mono-materials. Chinas leadership could reshape supply chains,remarked a European industry analyst.  

 Conclusion  

The successful conclusion of this meeting marks a milestone in Chinas packaging industry. By harmonizing innovation with sustainability, the revised GB/T 21302 standard will empower businesses to meet tomorrows challenges while safeguarding todays resources. GBPI Guangzhous role as a convener and innovator highlights its growing influence in shaping global packaging standards.
