After talking about packaging materials, let's take a look at the form that is convenient for consumers.
First of all, the one-way outlet valve is absolutely necessary, the air in the coffee bag can go out, but the outside air can't get in.
Why do you need a one-way outlet valve? Because after the coffee is roasted, it will continue to react and discharge carbon dioxide. If there is no one-way air outlet valve, the bag will swell and even burst the coffee bag.
The one-way air outlet can prevent the outside air from entering, and gradually the oxygen content of the air in the bag will decrease. Therefore, for coffee beans, the air valve is a device that allows only air to flow in, effectively slowing down the coffee beans. The rate of aging, so as to ensure the aroma of the coffee beans.
Think about what a blissful moment a consumer can smell the aroma of coffee when they open a coffee bag with a valve.
Secondly, Stand Up Pouches with ziplock is the bag type that consumers often choose to use, especially for one-pound, half-pound, or even 1/4-pound coffee bean packaging, because consumers often do not use it once. After getting all the coffee beans, there is a zippered coffee bean bag sealing design, which will be very convenient to seal the remaining beans.
The stand-up bag is convenient for consumers to display on the cabinet, and it is also convenient to find different beans. It would be a bit of a hassle to find the coffee beans that you want to drink if all of them are lying in the cupboard!
In addition, some operators will open a transparent window in the bag so that consumers can see the condition of the beans inside. These are all designs to provide consumers with a good user experience.
