Our kraft paper flat bottom coffee bag features a front zipper and optional valve, allowing easy product filling and re-sealability, along with strong shelf presence and space utilization. The pouch maintains product freshness with a metalized inner layer.

Natural  Brown kraft paper.

Metallized foil lining, high barrier and waterproof. 

Food grade PE inside layer, FDA food grade certified.

Heat sealable, sealed by heat sealer.

You need to have a heat sealer, there are plenty available at reasonable prices. Once you have that they seal perfectly and then the zip portion can be used but needs to be heat sealed first.

The bag is paper, foil, and plastic all laminated together. It's not recyclable unless you painstakingly separate all these materials.                                                                

Ink stamping would work just fine.
