What Makes 3 Side Seal Pouches Right for Your Product?

A 3 side seal pocket is a level, rectangular bundle with three factory-sealed edges—leaving one open conclusion for you to fill and seal. This basic plan understands three basic bundling challenges:

1. Maximum Freshness Protection

Multi-layer films (PET/AL/PE or PA/PE laminates) create an airtight barrier that blocks:

· Moisture (prevents clumping in powders)

· Oxygen (extends shelf life by 3-6 months vs. standard packaging)

· Light & contaminants (preserves flavor and color)

Real-world impact:A U.S. nibble brand decreased item returns by 34% after exchanging to our aluminum-laminate pockets.

2. Shipping & Storage Savings

The flat profile means:

· 40% more unitsper pallet vs. stand-up pouches

· Lower freight costs(reduced dimensional weight)

· Faster stackingin warehouses

Taken a toll example:A 10,000-unit arrange spares around $320 in shipping compared to inflexible holders.

3. Production Line Compatibility

Our pouches integrate seamlessly with:

· Vertical/horizontal form-fill-seal machines

· Vacuum packaging systems

· High-speed automated lines (tested up to 200 pouches/min)
