Coffee is a popular beverage all over the world, especially in Europe and America. When we buy coffee in the supermarket, we can see that coffee is packaged with different coffee packaging materials. But why does coffee need packaging? It protects it from the following effects:
1. Environment: Coffee will spoil in contact with air. If the coffee is directly exposed to the air, the greater the area in contact with the air, the faster it will deteriorate.
2. Oxygen: Can interact with the aroma of coffee components, especially the oxidation of fat, the smell of erosion.
3. Temperature: Freshly ground coffee powder will quickly absorb the moisture in the air, so that the weight of coffee increases, reducing the purity of coffee powder. And the work is complicated by the internal molecular pressure created by water. During roasting, coffee beans produce more carbon dioxide, which further reduces the aroma.
Here's why we chose the packaging for coffee:
1. Extend the shelf life of coffee, avoid coffee and air, oxygen and moisture contact, avoid the loss of fragrance.
2. The coffee packaging materials should be strong enough to avoid accidental tearing or damage by external pressure.
3. It can avoid the influence of air and humidity.
So what kind of packaging materials should we choose for coffee?
Coffee packaging material is the key to ensure the quality of coffee in the field of purchase, sales, storage and circulation. A delicate and unique coffee packaging bag can not only give people the enjoyment of beauty, but also directly stimulate consumers' desire to buy, so as to achieve the purpose of promoting sales.
Coffee packaging is available in a wide variety of materials. The raw material for the manufacture of coffee bags is laminated paper, because it not only ensures that the coffee beans are not oxidized but also ensures that the aroma will not be lost, and at the same time has sufficient strength to ensure that the package will not be damaged by air pressure and can be stored for up to two years.
Different types of coffee packaging are also made of different materials. Generally, the raw coffee bean packaging material is relatively simple, which is a common sack material. Instant coffee packaging also has no special material requirements, basically using general food packaging materials. The coffee bean (powder) packaging generally adopts an opaque plastic composite material and a relatively environmentally friendly coated paper composite material due to requirements for oxidation prevention and the like.
