Characteristics & Custom Packaging for Different Ready Meals
1.Cooked Meat Ready Meals
Product Features
High protein and rich soup content. Meat products easily breed spoilage bacteria. Grease oxidizes quickly and produces rancid odors during storage.
Recommended Gas Formula
CO₂ 30%–45% + N₂ balance
Suitable Packaging Form
Vacuum replacement MAP packaging. High-concentration CO₂ provides strong antibacterial performance, while nitrogen supports the tray shape to avoid collapse and extrusion deformation.
2.Mixed Meat & Vegetable Meals
Product Features
Combination of meat, stems and leafy vegetables. Different ingredients have different respiration and oxidation rates, easily causing partial yellowing, discoloration and deterioration.
Recommended Gas Formula
CO₂ 25%–35% + N₂ balance
Suitable Packaging Form
Balanced precision MAP packaging. Stabilizes both meat color and vegetable freshness, ensuring consistent quality during long-term shelf display.
3.Seafood Prepared Dishes
Product Features
Seafood has extremely high deterioration speed. It is sensitive to oxygen and bacteria, prone to fishy odor and microbial spoilage even under refrigeration.
Recommended Gas Formula
CO₂ 40%–55% + N₂ balance
Suitable Packaging Form
Deep vacuum replacement MAP packaging. Ultra-low oxygen environment suppresses bacteria metabolism and greatly extends cold storage shelf life for long-distance shipping.
4.Vegetable & Light Ready Meals
Product Features
High enzyme activity and strong respiration. Vegetables easily wilt, lose crispness and turn yellow after packaging.
Recommended Gas Formula
CO₂ 20%–30% + N₂ balance
Suitable Packaging Form
Gentle precise MAP packaging. Avoid over-squeezing, retain vegetable crispness, and maintain bright retail appearance.
Core Advantages of Vacuum Replacement MAP for Ready Meals
1.Ultra-low residual oxygen (＜0.5%) effectively prevents oxidation, oil rancidity and discoloration
2.High gas precision (±1%) ensures uniform freshness for every batch
3.Non-compression packaging perfectly maintains dish shape and texture
4.Physical fresh-keeping reduces preservative reliance, meeting healthy food standards
5.Greatly expands cold-chain distribution radius and improves product market competitiveness
