Laser perforation in MAP packaging: improving freshness with precision technology
MAP Food Packaging
In the ever-changing world of food packaging, modified atmosphere packaging (MAP) has become a popular solution to preserve the freshness of food by altering the atmosphere inside the package to reduce the growth of spoilage organisms. One of the most innovative advances in MAP technology is laser perforation, a process that optimizes airflow and gas exchange to improve shelf life and product quality.
Laser perforation refers to the process of using a focused laser beam to create small, controlled holes in packaging material. These microscopic perforations allow for controlled gas exchange, which is especially important for fresh produce and perishable items that require varying levels of oxygen and carbon dioxide throughout their shelf life.
Laser technology can create precise, evenly spaced holes with minimal heat, ensuring that the integrity of the packaging material is maintained while still allowing the necessary gas flow.
Main advantages of laser perforation in MAP packaging
Increased freshness and shelf life
For fresh produce, such as fruits and vegetables, the tiny perforations help regulate the respiration rate of the produce, slowing the aging process and preserving the color, taste and nutrients of the food longer.
Accuracy and consistency
One of the main advantages of laser perforation over traditional methods is its accuracy. Laser systems can create holes of exact shapes and sizes, allowing for consistent gas flow and a more controlled atmosphere within the package.
Customization for different products
Different foods require different levels of oxygen and carbon dioxide to stay fresh. Laser perforation allows customization of perforation patterns to meet the specific needs of each individual product
Minimized ecological footprint
Increased food shelf life contributes to a decrease in overall food waste. This makes laser perforation a more sustainable option for the food packaging industry.
