The TRI-1300A is engineered for high-barrier and specialty flexible packaging applications where a simple two-layer film isn't sufficient. Typical 3-layer structures include:

• 
  

  PET / Aluminum Foil / CPP: The classic high-barrier structure for retort pouches (ready meals, pet food) requiring maximum protection from oxygen, light, and moisture.

  
  


• 
  

  BOPP / Metallized BOPP / PE: Used for premium snack foods and coffee packaging, combining printability, barrier properties, and heat-sealability.

  
  


• 
  

  Paper / PET / PE: Common in stand-up pouches for dry goods or liquid soaps, where paper provides stiffness and a premium look, while PET and PE provide barrier and sealing.

  
  

The TRI-1300A's precise tension control across all three unwinds ensures that even delicate materials like foil or thin films are combined without wrinkles or tears.
