6. Modified Atmosphere Packaging (MAP) Machines

MAP Machines are designed to replace the air inside the packaging with a carefully controlled mixture of gases, such as oxygen, carbon dioxide, and nitrogen. This modified atmosphere helps to slow down the aging process, inhibit the growth of bacteria, and maintain the freshness, color, and texture of the vegetables.

Features:

Sealing Method: Alters the atmosphere inside the packaging to prolong freshness.

Use: Extends the shelf life without using preservatives.

Suitable For: Fresh-cut vegetables, organic produce, etc.
