What types of coffee packing bags
Many people are keen on drinking coffee in life, but few people will know about coffee bags. Today, Soonk Packaging machine factory shares some information about coffee Packaging.
There are four common types of packaging for coffee bags, each of which also represents a certain amount of information. General red packaging of coffee, the taste is generally thick, can let the drinker quickly wake up from last night's good dream. Black pack coffee, belongs to the high quality coffee. The golden package of coffee symbolizes wealth and wealth, indicating the best coffee. Coffee in blue, usually "decaffeinated" coffee. Details of coffee packaging machine packaging bags are as follows:
First, non-airtight coffee packaging: this is the most economical kind of packaging. It's usually used by small local bakeries because they guarantee a quick supply. Coffee beans can be used up in time. Beans packed this way will last only a short time. It's actually called an air pack, a bag filled with air, and of course the bag or container is airtight. The packaging simply blocks out moisture, flavor loss and light from the beans, but the beans are oxidized by the air in the bag or container over a long period of time, resulting in a shorter tasting period.
Second, airtight packaging: after loading the coffee, vacuum and seal it. Because carbon dioxide is formed during baking, the packaging can only be used after the coffee has been degassed for a period of time, so there is a storage interval of several days. Coffee beans last longer than ground coffee. Low cost due to no air separation during storage. Coffee packed this way should be used up within 10 weeks.
Third, vacuum packaging: there are two conditions for making vacuum packaging: 1. Vacuum the air. 2. A flexible and soft material. Of course, the technology can be applied to some hard materials, but it is common to use some soft materials, making it a hard product like "bricks". This way the coffee is tightly packed with the packaging material, but it must be the fully vented coffee bean, otherwise the coffee bean's own exhaust reduces the tightness of the package and makes it soft and bloated. This is what you see in most of the "bricks" in the supermarket: coffee grounds, not coffee beans.
Pressurized packaging: this is the most expensive way to store coffee for up to two years. After a few minutes of roasting, the coffee can be vacuumed. Add some inert gas and maintain proper pressure inside the package. Coffee beans are stored under pressure, allowing the aroma to flow over the fat, thereby improving the flavor of the drink. Such packaging is often used on watered-down coffee beans, which tend to have a shorter shelf life and a less savoury flavor. If the container is a hard material, there will be a pressure difference between the coffee beans themselves and the tank after the vacuum. Coffee beans release gases that saturate the environment and inhibit the aroma. In general, hard materials are not vacuumed as thoroughly as soft materials.
In fact, the packaging of coffee bags is also the most common in our life. Those who like to drink coffee will know that there are various types of packaging for coffee. I believe you can have a new common sense on the packaging of coffee bags. SOONK coffee packaging machine manufacturer offers you more details about coffee packaging.
