Does the packaging material have a great influence on the raw coffee beans? What kind of packaging do you like for coffee beans?

Drinking a cup of delicious coffee, you may not think that these coffee beans are transported from raw beans to the roaster, and then roasted to get a good cup of coffee.

So will the packaging of raw coffee beans affect coffee beans? after one-stop transportation and the passage of time, this will always have a certain impact on the shelf life and quality of coffee beans. In Qianjie coffee, from the coffee beans received, there will be these kinds of packaging, gunny bags is the most common packaging, as well as vacuum bags, plastic bags. Then what are their advantages and disadvantages? let's take a look at them together.

Advantages and disadvantages of burlap

Canvas made from natural fibers extracted from plants, jute or jute is the most traditional material used to make coffee bags. This is an environmentally friendly option; according to the Food and Agriculture Organization of the United Nations, it is "100% biodegradable, recyclable and therefore environmentally friendly." It is also durable and relatively affordable, and is by far the oldest coffee packaging material.

However, it does not provide moisture or oxygen protection-these two factors are related to poor coffee quality and even defects such as mold. The bag is permeable.

In addition, jute bags traditionally hold 60 kilograms of coffee (or 70 kilograms in some countries). At the same time, plastic bags and container liners can store more than 1 to 20 tons of green beans. Depending on the batch stored or shipped, the manufacturer may decide to choose a larger and more efficient storage option.

Advantages of plastics

The most common ones are made of polyethylene or polypropylene, and plastic storage options range from 60kg bags to large bags and container liners. Compared with jute, this material is cheaper and more moisture-resistant and gas-proof, but still permeable.

High vacuum cost

When coffee is vacuum packed, it is also stored in watertight plastic bags. Then, in addition to airtight isolation of raw coffee, negative pressure is generated to remove all air. It is generally believed that multi-layer vacuum packaging is the most effective way to maintain the quality of raw coffee. However, due to the high cost, this method is usually only used for samples or special boutique coffee in small and nanometer quantities.

High barrier effect

Professor Fl á vio Meira Bo é m is an agronomic engineer who specializes in vegetable production. He has devoted himself to the study of coffee for the past few years. A high-barrier bag is "a package with different components and structures that can prevent the exchange of gas and water between the interior and the atmosphere," he said.... It is a package with high impermeability. "

Although more expensive than other types of packaging, high-barrier bags are designed to maintain coffee quality over time by preventing chemical reactions with moisture and oxygen. You can find high barrier packaging in all sizes, including container lining.

Of course, what kind of packaging materials for coffee is not our own control, as long as we can ensure the quality of coffee is the ultimate goal.
