What are retort pouches?


Retort pouches are a type of high-temperature resistant flexible packaging that can withstand high-temperature and high-pressure sterilization at 121℃-135℃. Food is cooked, sterilized, and sealed inside in one step, and then has a shelf life of 12-18 months at room temperature.


They are lighter than metal cans and more convenient than frozen foods; simply open the pouch and heat before eating.


Core Technology: Multi-layer Composite


Retort pouches are not ordinary plastic; they have a three-layer composite structure:


Layer | Material | Function


Outer Layer | PET | Strong and scratch-resistant, printed with patterns


Middle Layer | Aluminum foil or Nylon | Barrier to oxygen, moisture, and light


Inner Layer | CPP | High-temperature resistant, direct contact with food


Barrier Performance: Oxygen permeability ≤0.1cc/m²/day, water vapor permeability ≤0.5g/m²/day, preservation effect comparable to metal cans.


Transparent Version: Uses nylon instead of aluminum foil, allowing visibility of the food, but with slightly lower barrier properties.

Q1: How long does the production and delivery cycle usually take?

A: From design confirmation and plate making to production and delivery, it usually takes 4 to 8 weeks. The time mainly depends on plate roller manufacturing (e.g., new plate making takes 1-2 weeks), material procurement, and production scheduling. It may take longer during peak seasons.


Q2: What is the typical minimum order quantity?

A: For customized designs (size, material, pattern), suppliers usually have a minimum order quantity requirement, typically ranging from 100,000 to 500,000 units. For "standard" bags using the supplier's existing printing plates, the minimum order quantity can be significantly lower.


Q3: What are the main factors affecting the price?

A: The main factors are: material structure (aluminum foil bags are usually cheaper than transparent high-barrier bags), size and thickness, printing colors and area (spot colors and full-coverage printing are more expensive), and order quantity. Surface treatments (such as matte finish) will also increase the cost.
