As a packaging-focused option within the GrainGuard coffee bean hermetic jute liner range, the product is available in S, M, and L sizes and in Basic, Pro, and Premium grades.

Product Introduction

The GrainGuard coffee bean packaging jute hermetic liner is developed for packing stations, cooperatives, dry mills, exporters, and roasters that want to improve the internal protection of jute sack packaging without changing established handling practices. Jute sacks remain widely accepted in the green coffee trade because they are durable, stackable, easy to identify, and compatible with standard warehouse and export operations. However, jute is naturally breathable and cannot provide a controlled internal barrier against moisture exchange, oxygen, insects, dust, or external odors on its own.

The liner is placed inside the jute sack before filling. Green coffee beans are loaded directly into the liner, which separates the product from the outer jute material and the surrounding packing environment. After the target weight is reached, the liner is gathered and closed using the specified cable-tie and heat-sealing procedure, while the outer jute sack is sewn or closed according to the buyer's normal packing method.

This product page is specifically focused on the final packaging stage after sorting, grading, dry milling, cupping approval, or lot preparation. It is suitable for coffee that will move from a packing area into palletized storage, export warehouses, inland transport, container loading, or customer delivery. The S, M, and L sizes support different lot formats, while Basic, Pro, and Premium grades allow buyers to match the packaging solution to coffee value, handling time, transport conditions, and budget.

Packaging Workflow

1. Prepare a clean, dry jute sack and confirm that it is free from sharp objects or contamination.
2. Insert the hermetic liner and open it fully so that the film follows the shape of the outer sack.
3. Fill the green coffee beans directly into the liner and verify the target packing weight.
4. Carefully reduce excess air without puncturing or overstressing the film.
5. Gather the liner mouth, apply the cable tie, and heat seal according to the approved packing procedure.
6. Close or sew the outer jute sack and proceed with labeling, palletizing, storage, or shipment.

Size and Grade Selection

Select the liner size according to the actual sack dimensions and target filling weight. S is suitable for small lots and trial packing, M supports medium-capacity and specialty programs, and L is the normal option for standard 60-70 kg export sacks. Grade selection should consider coffee value, expected holding time, climate, transport route, customer requirements, and budget. Basic is suitable for regular commercial packing, Pro provides a balanced solution for export and higher-value lots, and Premium is positioned for specialty coffee, longer routes, and more demanding quality programs.
