Core Analysis of Retort Pouch (Soft Can): Function, Advantages, and Material Essence

A retort pouch, or "soft can," uses high-pressure steam sterilization (121-135°C) to make food shelf-stable for 1-2 years without refrigeration.

Key benefits:

1. Long Shelf Life & Freshness: Preserves flavor and nutrients better than cans.

2. Convenience: Lightweight, easy to open, and often microwavable.

3. Cost-Effective: Saves on shipping and storage due to light weight.

4. Safety: Multi-layer materials (e.g., PET/Al/CPP) block air and moisture.
