Laminated pouches and cans with one-way valve feature are well suited as coffee packaging. The feature prevents entry of gasses from outside environment but allow exits of internal accumulating air.
A freshly roasted coffee should be let stand, at least overnight, with loose cover. It is essential to bent off the accumulating carbon dioxide. Packing it immediately will likely to result in a bloated package. The valve feature removes both the hassle of waiting and package bloating.
I was wrong to think both package types were not available here in our country. I just saw laminate samples which came from:
Afdell Packaging Solutions, Inc

Tel. Nos. 244-4049, 309-3216
Telefax No. 242-9114
It is a generic packaging, no label. I never know more info. Please inquire to above contact. However, I am very sure it can be procured in low quantities. Enough reason for you to try and eventually use the appropriate coffee packaging.
