69kg Hermetic Jute Liner

The durable 69kg hermetic jute liner offered by GrainGuard, a professional manufacturer in China. This hermetic jute liner helps reduce green coffee beans’ exposure to moisture exchange, oxygen, insects, dust, external odors, and handling contamination during warehouse storage, export preparation, container loading, and international shipment. When correctly filled and closed, it supports a more stable internal environment and helps maintain coffee quality throughout the supply chain.
As a capacity-specific option within the GrainGuard coffee bean hermetic jute liner range, the product is available in Basic, Pro, and Premium configurations for different coffee values, storage conditions, protection requirements, and purchasing budgets.
GrainGuard also supports OEM printing, private-label packaging, customized carton packing, wholesale orders, and factory-direct export service from Qingdao, China.

Product Introduction

The GrainGuard 69kg hermetic jute liner is designed for coffee exporters, cooperatives, dry mills, traders, and roasters that use standard large jute sacks but require improved internal protection for green coffee beans. In many coffee-producing regions, 60-70 kg jute sacks remain a widely used export packaging format because they are practical for filling, stacking, handling, storage, and international trade. However, jute is naturally breathable and cannot provide sufficient protection against moisture exchange, oxygen exposure, insects, external odors, dust, and warehouse contamination on its own.

When placed inside a traditional jute sack, the hermetic liner creates a separate inner packaging layer around the coffee beans. This helps reduce direct contact with the jute material and limits exposure to changing warehouse and transport conditions without altering the accepted outer packaging format. The liner can be used after dry milling, during origin storage, while coffee is waiting for grading, documentation, or container booking, and throughout delivery to importers, traders, and roasters.

This product is specifically focused on the nominal 69 kg export-sack application rather than sample bags or medium-capacity formats. Its L-size dimensions are developed for common 60-70 kg green coffee and cocoa packing requirements. Basic, Pro, and Premium options allow buyers to select an appropriate balance of cost, barrier performance, storage requirements, and product positioning.
