Convenience and efficiency are major factors influencing customer decisions in today's fast-paced environment, particularly in regard to food packaging.Presenting a ground-breaking solution: the high temperature resistance retort pouch. This novel format is changing how we store, transport, and consume shelf-stable foods in contrast to conventional rigid packaging.

What is a Retort Pouch?

Retort pouch, which is composed of a lamination of metal foil and flexible plastic.It provides the same durability and shelf-stability as conventional cans and glass jars but is lighter and more flexible.The food inside these pouches stays safe and fresh for extended periods of time since they are made to withstand high-temperature sterilization. 

Why Retort Pouches Matter in Food Packaging‌？

The Secret to Their Strength: Retort bags are engineered to withstand even the harshest conditions, thanks to their robust multi-layer design.Usually, they mix:

  - ALOX-PET Surface Layer: Provides enhanced barrier properties and durability, ensuring the pouch retains its integrity under high heat.

  - NY Composite Layer: Offers high strength and toughness, with excellent puncture resistance to prevent damage during handling and cooking.

  - RCPP Inner Layer: For products cooked at 121 degrees, we use RCPP that maintains its quality without delamination. For higher demands, 135-degree RCPP ensures superior performance.

The pouch is guaranteed to stay intact even when sterilized at temperatures of 135°C or higher thanks to this 'sandwich' design.
