In the modern food packaging industry, blister packaging has become an important means of food preservation due to its significant advantages in extending the shelf life of fresh food.
1. Preservation principle of blister packaging
- Vacuum packaging: vacuum technology is used to extract the air in the package to form an oxygen-free environment, inhibit the growth of bacteria and microorganisms, and thus extend the shelf life of food.
- Microporous preservation technology: by punching holes in the packaging material, the food can breathe in the package, adjust the internal gas composition, and slow down the aging and deterioration of the food.
- Water-blocking and oxygen-blocking functional materials: a single material with water-blocking and oxygen-blocking functions is used to prevent external oxygen and moisture from entering and maintain the freshness of the food.
2. Technical advantages of blister packaging
- Extending the shelf life: blister packaging can effectively extend the shelf life of fresh food and reduce food deterioration and waste. For example, vacuum blister packaging can extend the shelf life of meat and seafood several times.
- Maintain food quality: By isolating oxygen and moisture, blister packaging can maintain the original taste and nutritional value of food and enhance consumers' eating experience.
- Moisture and mildew resistance: Blister packaging has good moisture and mildew resistance, and is particularly suitable for packaging foods that are susceptible to moisture, such as nuts and dried fruits.
- Environmental protection and sustainability: Many blister packaging uses degradable materials, which meets environmental protection requirements and reduces the impact on the environment.
