Multi-layer bags (kraft · foil · HDPE)
Outer food-grade kraft for stack strength; inner aluminium-laminate or HDPE liner — or both — for the actual barrier. Foil laminate has the best barrier + light exclusion; plain HDPE alone is cheaper but weaker. Spec foil laminate for quality-sensitive retail.
- Heat-sealed inner foil pouch
- Silica desiccant sized to pack volume
- Optional N₂/CO₂ flush where equipment exists — specify for premium supplement/cosmetic
- Outer kraft sewn or heat-welded
- Ask for a photo / tech drawing of the construction
