How Does a High-Barrier Stand-Up Pouch Achieve "High Barrier"?
The performance of a barrier stand-up pouch comes from its multi-layer composite structure. Each layer has a specific function:
A typical high-barrier structure might look like this:
1. Outer layer (Substrate/Print Layer)
Materials: BOPET (Polyester), BOPP (Polypropylene), Nylon (PA), or Paper.
Function: Provides mechanical strength, puncture resistance, and a high-quality surface for vibrant printing and graphics.
2. Intermediate barrier layer (core functional layer)
Materials:
Aluminum Foil (Al): Provides an absolute barrier against light, oxygen, and moisture. Common for coffee, pharmaceuticals, and sensitive supplements.
Transparent Barrier Films: SiOx or AlOx coated films (e.g., KPET or KOPP) offer excellent, see-through oxygen and moisture barriers. EVOH is a high oxygen barrier, often used as a middle layer in retort applications.
Function: This is the critical layer that determines the pouch's shelf-life extension capabilities.
3. Inner layer (heat seal layer)
Materials: Polyethylene (PE) or Cast Polypropylene (CPP).
Function: Provides a safe, food-grade inner surface that can be heat-sealed to form the pouch's seams and create a strong, airtight closure.
These layers are bonded together using lamination processes like dry laminating or extrusion laminating.
