Official  Product Name: SuperGrainbag® Sample


The GrainPro Sample Bag is a resealable bag with capacities of approximately up to 850 & 500 grams for green or roasted coffee samples (may vary depending on coffee variety). This Ultra-Hermetic™ coffee solution is made of high-strength polyethylene with a proprietary barrier layer that protects coffee and other sample commodities from air and moisture ingress. It retains the freshness of stored samples and protects against insect infestation.

It is equipped with a single-track hermetic zipper and can also be sealed with heat welding. A tear notch at the top of the bag makes it safe to cut through the welding as well as easy access to the stored commodity.
