FAQ
What valve options are available for 500g coffee bags?
We offer one-way degassing valves that release CO₂ while blocking oxygen. Standard adhesive valves are placed 70 mm from the top seal; screw-in valves are available for premium lines.
Which barrier laminate preserves coffee freshness longest?
PET 12µm / AL 7µm / PE 80µm delivers OTR ≤ 0.5 cc/m²·day and targets 12+ months shelf life. Kraft-front structures with VMPET provide 6–9 months for shorter shelf-life roasts.
Can I order a 500 PCS trial before bulk production?
Yes. MOQ is 500 PCS per size and artwork. We produce a printed sample proof for your approval before starting the trial run.
