Defect 1: Packaging Material Permeability Leads to Aroma Loss
Although vacuum packaging can block oxygen, its barrier effect against certain aromatic compounds is limited. The natural aromatic components in rice slowly escape through the packaging material, particularly when stored in higher temperature environments where aroma loss accelerates. After extended storage, the natural fragrance of the rice upon opening is significantly diminished, affecting the eating experience.
Solutions:
- Develop high-aroma-barrier composite materials: Use nanomodification technology to enhance the packaging material's barrier properties against aromatic substances, adding an aroma-blocking coating on top of the aluminum foil layer
- Optimize storage condition recommendations: Clearly mark the optimal storage temperature range on the packaging, advising consumers to store unopened vacuum-packaged rice in cool environments
Defect 2: Lack of Effective Measuring Convenience After Opening
After opening vacuum packaging, traditional packaging designs make precise measuring and convenient resealing difficult. Consumers often need to transfer rice to other containers or scoop directly from the exposed bag, which not only increases the risk of moisture absorption but also compromises usability. Particularly during humid seasons, repeated opening and closing can easily lead to deterioration of remaining rice.
Solutions:
- Design an integrated measuring and sealing system: Incorporate a graduated dispensing device at the bag opening that enables precise portioning while maintaining sealing integrity
- Provide dedicated freshness accessories: Include a portioning scoop and silicone sealing plug with the packaging, ensuring effective resealing after each use to extend the shelf life after opening
