Spout Pouch Materials Options

Spout pouches are constructed from a combination of materials that offer durability, flexibility, and protection against external factors such as moisture, oxygen, and light. The material composition varies depending on the product being stored, but the common components include:

Outer Layer

Material: Polyester (PET)
  • Purpose: Provides strength, printability, and a high-quality finish.
  • Benefits: Durable and resistant to external factors like scratches and UV rays.

Middle Layer

Material: Aluminum Foil or Metallized PET
  • Purpose: Acts as a barrier layer to block oxygen, moisture, and light.
  • Alternative: Nylon (PA) is sometimes used for lightweight products.
  • Benefits: Preserves freshness and extends shelf life.

Inner Layer

Material: Polyethylene (PE)
  • Purpose: Food-grade layer that comes in direct contact with the product.
  • Benefits: Heat-sealable and provides excellent leak-proofing.

Optional Layers

Nylon (PA): Enhances puncture resistance, ideal for sharp-edged or dense products.
EVOH (Ethylene Vinyl Alcohol): Used for high-barrier properties without aluminum, making the pouch recyclable in some cases.
