Description de produit

Guardian Pro: Multi-Laminate Freshness Coffee Bag

Where Material Science Meets the Art of Roasting

For roasters who define quality by the first crack and the last sip, we present the Guardian Pro. This premium liquid-style bag is the result of material science explicitly engineered for coffee preservation. We go beyond simple barriers; we've architected a proprietary multi-laminate film structure that systematically defeats the three enemies of freshness: oxygen, light, and aroma loss. This isn't packaging—it's a controlled-environment vault for your craft.

Engineered Laminate: A 4-Layer Fortress

Our bag is built using a state-of-the-art reverse-printed, multi-layer laminated film. This structure is precision-engineered for maximum barrier performance and luxurious feel:

Layer 1 (Outer Layer / Printing Surface): 12-15 micron PET or Matte OPP. Provides exceptional graphic printability for stunning, high-resolution branding with superior scuff resistance and a smooth or luxe matte tactile finish.
Layer 2 (Core Barrier Layer): 5-7 micron Metallized PET or EVOH. The heart of the system that creates an impenetrable barrier against oxygen and light (99.9% UV barrier).
Layer 3 (Tie Layer / Structural Core): 15-20 micron Nylon or LLDPE. Provides phenomenal puncture resistance, tensile strength, and flexibility while preventing pinholes.
Layer 4 (Inner Sealing & Aroma Lock Layer): 50-70 micron LDPE or food-grade PE Blend. Ensures strong, reliable heat seals and locks in aromatic compounds with a safe food-contact surface.

Integrated Freshness Technologies

Aroma-Lock™ One-Way Valve: Precision-calibrated to vent CO₂ without allowing oxygen re-entry or significant aroma escape.
Light-Lock™ Opacity: Achieved through metallization, opaque pigments, and multiple material layers for total darkness.
Reclosable Precision Zipper: Integrated wide-track zipper for perfect, airtight resealing.

Form & Function Synergy

The laminate is specifically engineered for the "liquid stand-up pouch" form factor. It maintains the perfect balance of stiffness for clean, upright standing and flexibility to collapse elegantly around coffee, minimizing headspace.

Why This Film Structure Wins

Superior Barrier Performance: Combination of specialized materials exceeds single-layer or co-extruded film barriers.
Brand Excellence: Reverse printing between layers ensures vibrant, scratch-proof, food-safe graphics.
Durability & Integrity: Nylon/LLDPE strength and thick sealant layer prevent leaks and breakages.
Proven Freshness Extension: Industry benchmark for extending optimal freshness of whole bean coffee to 6-12 months.
