How to Choose the Correct Configuration

The correct coffee bean hermetic jute liner should be selected from the actual sack, commodity, route, and storage program rather than nominal capacity alone. A physical fit and sealing test is recommended whenever a new jute sack supplier, filling weight, material grade, or closing method is introduced.

1. Measure the outer sack: Provide the usable width and length, seam position, opening style, and internal space of the actual jute sack.

2. Confirm the target net weight: State the commodity, bean density, target capacity, and required headspace for gathering, cable tying, and heat sealing.

3. Choose the size: Use S for approximately 10-20 kg, M for approximately 25-35 kg, or L for approximately 60-70 kg after checking the physical fit.

4. Select the grade: Match Basic, Pro, or Premium to coffee value, storage period, route humidity, climate, buyer specification, and purchasing budget.

5. Validate the closure: Confirm cable-tie position, heat-sealer width, temperature, pressure, dwell time, and operator procedure using production samples.

6. Review handling risks: Check hooks, sharp sack seams, pallet boards, rough floors, compression, abrasion, and container surfaces that could puncture the liner.

7. Approve artwork and packing: Confirm printing, private-label information, labels, “No Hook” stickers, inner-pack quantity, master-carton markings, and mixed-size ratios.

8. Complete a trial pack: Fill, close, stack, palletize, and inspect a sample package before releasing a new configuration for bulk production.

Selection Guide

Selection Factor	Recommended Direction
Small or separated lots	Select S size for approximately 10-20 kg programs, micro-lots, trials, or easier lot separation.
Medium-capacity packing	Select M size for approximately 25-35 kg sacks and flexible cooperative, importer, or roaster handling.
Standard export sacks	Select L size for approximately 60-70 kg green coffee or cocoa packing after confirming sack dimensions.
Routine commercial shipment	Consider Basic grade where practical protection and cost control are the main priorities.
Higher-value or longer handling	Consider Pro grade where stronger material performance and a balanced barrier are required.
Specialty coffee or demanding routes	Consider Premium grade for longer storage, humid climates, sensitive lots, and quality-focused buyer programs.
Repeated warehouse handling	Use clear “No Hook” instructions and protect the liner from sharp edges, abrasion, puncture, and excessive compression.
New sack or sealing equipment	Complete a physical fit, filling, cable-tie, heat-seal, stacking, and transport trial before bulk production.
