Green Coffee Bean Hermetic Jute Bag Liner

As a professional manufacturer in China, GrainGuard would like to provide you quality green coffee bean hermetic jute bag liner, which helps reduce exposure to moisture exchange, oxygen, insects, dust, external odors, and handling contamination during origin storage, export preparation, warehouse holding, container loading, and international transportation. When correctly filled and closed, it supports more stable storage conditions and helps maintain green coffee quality throughout the supply chain.

The product range includes S, M, and L sizes for 10-20 kg, 25-35 kg, and 60-70 kg filling requirements, together with Basic, Pro, and Premium grade options. OEM printing, private-label production, customized packing, wholesale supply, and factory-direct export service are available from GrainGuard in Qingdao, China.

Product Introduction

The GrainGuard green coffee bean hermetic jute bag liner is developed for coffee businesses that already use jute sacks but require a cleaner and more protective inner packaging layer. Jute remains popular because it is strong, stackable, easy to handle, and widely accepted by exporters, importers, traders, and roasters. However, jute is naturally breathable and cannot provide an effective barrier against changing humidity, oxygen exposure, insects, dust, external odors, and warehouse contamination on its own.
By placing the hermetic liner inside the jute sack before filling, the beans are separated from direct contact with the outer jute material. After filling, the liner is closed according to the selected packing method to create a more controlled internal environment. The jute sack continues to provide the familiar external handling structure, while the liner supplies the primary internal barrier during storage and shipment.
Unlike a single-capacity product page, this product covers a complete jute bag liner range. The S size supports small lots and specialty coffee programs, the M size is suitable for medium lots and roaster or cooperative storage, and the L size is designed for standard 60-70 kg export sacks. Basic, Pro, and Premium options allow buyers to select an appropriate balance of cost, barrier performance, storage requirements, and product positioning.
The liner can be integrated into existing packing workflows without major changes to normal sack handling. It is suitable for use after dry milling, during grading and export waiting periods, in origin and port warehouses, during container transportation, and at importer or roaster storage facilities.
