Newly Identified Defects and Solutions for Vacuum-Packaged Rice（4）

The shrinking and tightening of vacuum packaging surfaces often causes key information such as nutrition facts and origin details to wrinkle and deform, making some text difficult to read. Additionally, the curved structure of the packaging frequently leads to barcode scanning difficulties during checkout, reducing supermarket efficiency. Consumers' purchasing willingness decreases when they cannot quickly access complete product information.

Solutions:

1. Implement zoned flat surface design: Create dedicated flat areas on the packaging surface for printing, using special heat-sealing processes to prevent shrinkage in these zones and ensure clear readability
2. Introduce smart identification technology: Place multiple backup barcodes on the packaging while adding QR codes linking to detailed electronic product information, enabling a "scan-to-know" convenient experience

During express delivery processes, vacuum packaging undergoes multiple handlings and potential impacts, making it susceptible to air leakage from sharp object collisions. Meanwhile, temperature fluctuations during transportation cause changes in internal and external pressure differences, potentially leading to bag expansion or shrinkage deformation that affects product appearance upon arrival. Standard vacuum packaging struggles to withstand the specific challenges of logistics processes.

Solutions:

1. Develop e-commerce specific packaging: Use three-layer composite puncture-resistant materials with added cushioning air chambers at the four corners to effectively withstand transportation impacts
2. Innovate pressure balance structure: Embed micro-porous pressure adjustment devices in the packaging to automatically regulate internal and external pressure differences, maintaining stable packaging morphology under various altitude and temperature conditions
