Coffee Storage Hermetic Jute Inner Liner

The GrainGuard coffee storage hermetic jute inner liner helps reduce exposure to moisture exchange, oxygen, insects, dust, external odors, and handling contamination during origin storage, export waiting periods, port holding, inland transport, and roaster inventory management. When correctly filled and sealed, it supports a cleaner and more stable storage environment for individual coffee lots.
As a storage-focused option within the GrainGuard coffee bean hermetic jute liner range, it is available in S, M, and L sizes and in Basic, Pro, and Premium grades. We supports wholesale orders, OEM printing, private-label packaging, customized carton packing, and factory-direct export service from Qingdao, China.

Product Introduction

The GrainGuard coffee storage hermetic jute inner liner is developed for coffee lots that must remain protected after processing and before final shipment or roasting. In origin warehouses, green coffee may wait for grading, cupping, buyer approval, documentation, container booking, or export consolidation. During this period, ordinary jute sacks remain exposed to changing humidity, air exchange, insects, dust, and odor transfer from nearby cargo because jute is naturally breathable. The liner is placed inside a clean, dry jute sack before filling. Green coffee beans are filled directly into the liner, after which the opening is gathered and closed according to the approved packing procedure, commonly using a cable tie and heat sealing. The outer jute sack can then be sewn or closed in the normal way. This two-layer system keeps the practical handling strength of jute while adding a cleaner internal barrier around the beans.
Because protection is applied at the individual-sack level, the product is useful for warehouses managing multiple origins, grades, screen sizes, processing methods, certifications, or buyer contracts at the same time. Separate lots can remain clearly identified while receiving added internal protection during origin storage, port holding, international shipment, importer warehousing, and roaster inventory control.

Origin and export warehouses managing multiple lots, origins, grades, and buyer contracts.

Storage and Handling Guidance

Use a clean, dry, undamaged jute sack before inserting the liner.
Open and align the liner fully so that coffee is filled into the liner rather than between the liner and sack.
Avoid punctures, sharp tools, hooks, rough floors, and damaged pallets during filling and handling.
Close the liner according to the approved packing procedure and verify the seal before sewing the outer sack.
Store packed sacks in a clean, dry, ventilated warehouse away from water, strong odors, chemicals, and direct contamination sources.
Use suitable pallets and warehouse controls; the liner supports storage protection but does not replace good warehouse practice.
