How to choose the suitable Coffee Bean Packaging Bags

2022-07-30

You just finished roasted coffee, how do you properly store the fresh coffee?You may be able to distinguish the quality of coffee, but have you paid attention to the quality of Coffee Packaging Bags?
Sometimes the quality of the coffee may be very good, but the wrong Packaging Bag is used, which greatly compromises its quality.

Now, I want to tell you how to choose the right coffee bean packaging bag.

1.Coffee type
There are many coffee bean bag types : Stand up bag, Flat Bottom Bag, Side Gusset Bag, flat bag, etc. You can choose according to your personal preference. It doesn`t matter.

2. Coffee Bag Material
Coffee beans need to be shaded, so three layers of material must be used, the key is how to choose these three layers of material.

PET/MOPP+VMPET/AL+PE/CPP
1) Coffee Bag Material: External layer
PET is glossy, MOPP is matt, just choose according to the effect you want.
2) Coffee Bag Material: Mezzanine
The VMPET is aluminized, and the AL is aluminum foil. The barrier of oxygen and moisture is good for both of material.
3) Coffee Bag Material: Inner layer
PE is the inner material of most plastic bags, it is the safest food grade material, so there is nothing to say. CPP is another inner layer material, but it is generally used when packaging lighter things. I do not recommended it for heavier products such as 500g, 1kg of coffee beans.

3. Coffee Bag Details

1) Coffee Bag Zipper

The zipper is of course a must, it can help us better store coffee beans. However, if you choose an organ bag, you can use a tin tie instead of a zipper.

2) Coffee Bag: One-way exhaust valve
The valve is the most important part, and it has many benefits.
Coffee Bag: Exhaust (anti-swelling bag):
Coffee beans will continue to release carbon dioxide several times the volume of the coffee beans themselves for a period of time after roasting. A one-way exhaust valve is installed on the coffee packaging bag to discharge excess carbon dioxide out of the bag to prevent the bag from bursting.

3) Coffee Bag: Round corner and easy tear notch

Coffee Bag: No air intake (coffee preservation):
In addition, the one-way exhaust valve can also block the oxygen outside the coffee bag from entering the bag, preventing the coffee beans from oxidizing and causing the aroma to quickly spread, thereby absolutely ensuring that the flavor of the coffee beans remains unchanged.

3) Coffee Bag: Round corner and easy tear notch
These little details are of course indispensable, which can make the packaging more convenience and smart.

Okay, that`s all about coffee bean packaging.
Hope it is helpful to how to choose the right coffee packaging bag.
