How to choose the most suitable coffee packaging bags

Good coffee packaging bags can extend the shelf life of coffee, which affects the flavor of coffee and also affects customers’ impression of our coffee. When customers hear a certain coffee brand, their packaging will immediately appear in their minds, so a packaging design that leaves a deep impression is particularly important. In addition to packaging design, roasters need to consider the following five aspects when choosing the best coffee packaging bags.

1. Bag type

There are many types of packaging bags, among which the following three types are commonly used for coffee packaging:
Doypack(stand up pouch)
Doypack is a very common bag type, and we usually add a zipper to it. Doypack is also known as stand up pouch. As the name suggests, it can stand up so that the information on the bag can be better displayed.

side gusset bag
Side gusset bag has expandable sides, which greatly increases its capacity. Although the side gusset bag does not have an expandable bottom, we can still make it stand upright when filled with coffee.

Flat bottom bag
The flat bottom bag looks a bit similar to the side gusset bag, but in addition to its expandable sides, it also has an expandable bottom. This design allows the flat bottom bag to stand firmly on the shelf. Because the production process of flat bottom bag is more complicated, its price will be relatively high.

2. Barrier performance

The shelf life of roasted coffee beans is generally short, so we must ensure that the coffee packaging bags has the ability to block oxygen and water vapor. We usually have more than three layers of materials for coffee packaging bags, which must include a layer of aluminum foil. Aluminum foil can well block oxygen and water vapor. However, we cannot blindly seal the coffee beans completely for the sake of barrier performance, because the roasted coffee beans will always release carbon dioxide. If the coffee packaging bags is completely sealed, one result will be that the bag will continue to expand until explode. In order to solve this problem, we will add a one-way exhaust valve to the coffee packaging bags. The carbon dioxide in the bag will be discharged out of the bag through this one-way exhaust valve, but the air outside the bag cannot be exhausted through this one-way exhaust valve. valve into the bag.
Of course, this coffee packaging bags with a one-way exhaust valve is only suitable for coffee bean packaging. So how to increase the shelf life of coffee powder? The answer is vacuuming. The coffee powder packaging bags produced by Lide Packaging can be used for vacuuming.

3. Packaging process

Roasters can choose to package coffee manually or semi-automatically. If it is a side gusset bag, then we recommend using a semi-automatic packaging machine. Because the opening of the side gusset bag is relatively small, using manual filling of coffee beans will greatly slow down the packaging process.

4. Sealing

Coffee beans, especially coffee powder, will lose their original flavor soon after opening the package, so we must seal the packaging bag immediately after each use to prevent further loss of coffee aroma. At this time, the high-quality zippers we add to the coffee bags play an important role. The high-quality zippers used by Lide Packaging can still maintain the same sealing properties after being opened and closed multiple times. Together with the high barrier properties we use for the coffee packaging bags, The material can greatly increase the shelf life of roasters’ coffee products. However, due to technical problems, zippers still cannot be used well on side gusset bags. We will use sealing tin strips instead of zippers. As long as they are used correctly, sealing tin strips can provide the same sealing as zippers.

5.Style

Every company’s products need to differentiate themselves from their competitors, and packaging is one of the easiest ways to do this and the most intuitive way to build a brand. Therefore, we need to establish our own style for our packaging. It is best if all the company’s products use the same design style. This can increase the customer’s impression, and then the customer will first think of us every time they make a purchase in the future. brand.

The above 5 points are some of our experiences, but a successful product requires far more than the above 5 points. We need to adapt to the actual situation because the market is constantly changing and everyone’s needs are not fixed.
