Hermetic Liner Bag For Green Coffee Bean

Available in both Basic and Pro versions, GrainGuard factory’s Hermetic Liner Bag For Green Coffee Bean is engineered to fit seamlessly inside traditional jute bags, creating an airtight barrier that prevents moisture ingress, insect infestation, and oxidation while maintaining the classic aesthetic of jute packaging.

Product description

GrainGuard Hermetic Liner Bag For Green Coffee Bean combines traditional jute bag aesthetics with modern hermetic technology. Each liner consists of multilayered food-grade polyethylene material with exceptional gas and moisture barrier properties, ensuring that green coffee beans, cocoa beans, and other sensitive agricultural products remain fresh throughout their journey from farm to roaster.
The hermetic seal created by these liners eliminates the exchange of air and moisture between the stored commodity and the external environment. This oxygen-free storage environment naturally prevents insect development and mold growth, eliminating the need for chemical treatments while preserving the beans' germination potential, flavor profile, and aromatic characteristics.
Available in three sizes (Small, Medium, and Large) to accommodate different bag capacities from 10kg to 70kg, GrainGuard Jute Liners are supplied with cable ties and "No Hook" stickers for easy, secure sealing. The liners can be sealed using either cable ties for quick closure or heat sealing for long-term storage and international shipping.

Frequently Asked Questions (FAQ)

Q2: How do I seal the hermetic liner?
A: GrainGuard Jute Liners come with cable ties for quick sealing. For short-term storage and local transport, cable ties provide adequate sealing. For long-term storage and international shipping, we recommend heat sealing for maximum hermeticity. Each liner includes a heat-sealable area at the top.

A: When properly sealed, GrainGuard Jute Liners can preserve bean quality for 6-12 months or longer, depending on storage conditions. The hermetic seal prevents moisture ingress, insect infestation, and oxidation, maintaining freshness throughout extended storage periods.

Q6: Do I need to use pesticides or fumigants with these liners?
A: No. The hermetic seal creates an oxygen-depleted environment that naturally prevents insect development and mold growth, eliminating the need for chemical treatments. This makes them ideal for organic products and health-conscious businesses.

Q7: How do I choose the right size?
A: Choose based on your standard jute bag size and commodity weight: Small (10-20kg), Medium (25-35kg), or Large (60-70kg). The liner should fit comfortably inside your jute bag with enough material at the top for proper sealing.
