Introduction
Interpretation of GB/T 9106.2—2019, the National Standard of the People's Republic of China
1. Background and significance of the standard
GB/T 9106.2—2019 replaces the original GB/T 29345—2012, and mainly optimizes and supplements the specification classification, structural dimensions and technical requirements of aluminum easy-open steel cans. The formulation of this standard aims to meet the needs of industry development, improve product quality, and ensure the safety and functionality of food packaging.
2. Comparison of standard frameworks
| Standard version | Main changes |
|---|---|
| GB/T 29345—2012 | The old standard has relatively simple provisions on can type classification and structural dimensions, and does not cover modern diversified needs. |
| GB/T 9106.2—2019 | Added 202 series can types, optimized structural dimension parameters, and strengthened food safety requirements and test methods. |
Case Study: Comparison between 202 and 206 Series
The 202 Series is suitable for 330mL, 355mL and 500mL capacities, with tank heights of 122.22mm, 122.22mm and 167.84mm respectively. While the 206 Series has a larger outer diameter (such as 206/211 models) at the same capacity, it is suitable for scenarios with higher capacity requirements.
3. Interpretation of Core Technical Requirements
3.1 Tank Structural Dimensions
Key parameters such as tank height, outer diameter, necking inner diameter and flange width must strictly comply with the requirements of Table 2. For example, the can height of the 202 series is 122.22mm, and the limit deviation is ±0.38mm.
3.2 Performance of aluminum easy-open lids
The compressive strength of aluminum easy-open lids must reach ≥610kPa, and the bursting force and full opening force must not exceed 31N and 45N respectively. At the same time, the dry film mass of the sealing glue is 16~36mg and 26~46mg in the 202 and 206 series respectively.
4. Implementation suggestions
4.1 Strictly control material quality
Tin-plated steel sheets that meet the GB/T2520-2017 standard should be selected to ensure that the content of harmful elements is within a safe range. The inner wall coating must meet the requirements of GB4806.10, and the sealing glue should follow the GB4806.11 specifications.
4.2 Strengthen quality inspection
It is recommended to use automated inspection equipment for dimensional measurement and sealing tests. In particular, for the inner coating integrity test, a high-precision tester is required to ensure that the current value meets the standard requirements.
4.3 Optimize the production process
Introduce an intelligent production management system to monitor key process parameters in real time. Regularly maintain the tooling and molds to ensure that the dimensional deviation is within the allowable range.
