Do not ignore the importance of coffee bags for coffee preservation. The packaging you choose will affect the freshness, preservation efficiency and shelf life of coffee beans.

Whether you are a baker, a shopkeeper or a consumer, it is important to know the right bag for you.

The author interviewed Corina Ye, director of MT Pak, which makes coffee bags, and Barbara Croce, director of Gold Box Roastery UK, and customers of MT Pak, who will tell you some common types of coffee bags on the market, as well as how bakers and consumers should choose.

Four kinds of common coffee bean bags

Although there are many kinds of coffee bean bags on the market, they can be divided into four types according to the purpose of use:

1. Standing bean bag

"standing beanbags are common on the market, and this kind of beanbag is cheaper than other kinds," Corina said.

These bags are made up of two panels and a bottom corner plate, showing a triangular shape. They are also often used in chain bags that can be repeatedly sealed, and even if the bags are opened, they can maintain the freshness of coffee for a longer time. The combination of low price and high quality makes standing bean bags a popular choice for small and medium-sized stores.

The bottom corner plate also allows the bag to stand, giving the coffee beans more room to display. If you add more design, you can make a bag of coffee beans more eye-catching.

"Bean bakers can easily fill this kind of bag with coffee beans, because the opening of the bag is large, which makes the packaging operation more efficient and smooth."

two。 Flat-bottomed bean bag

The appearance of this kind of beanbag is very beautiful, the design of the square bottom makes the beanbag stand more firmly, makes its presentation more prominent, and can have a deeper modern design feeling depending on the material. If the use of chain bag design, so that the appearance and functionality (repeatable seal) coexist at the same time.

In addition, because of its corner plate on the side, it can hold more coffee beans in smaller bags. In other words, this makes storage and transportation more efficient and more environmentally friendly.

In addition, this kind of bean bag with breathable valve will be more ideal, coffee can be exhaust and aging in a normal time, which is also the main function of the valve. In addition, the chain allows users to use a small amount of coffee beans, and then re-seal the bags to keep them fresh.

The disadvantage of this kind of beanbag is that the production process is complicated, so its price is usually higher.

3. Rimmed bean bag

This is a more traditional but still very popular beanbag. It is sturdy, durable and suitable for packing large amounts of coffee. If you choose to pack a lot of coffee, such as a five-pound package, this kind of bean bag is more suitable.

These bags have a flat bottom design, when the bag is filled with coffee beans, you can stand by yourself, even if the bag is empty, you can stand if the bottom is folded.

These bags can be printed from a variety of angles, making them easy to brand, and they are also cheaper than other bags. On the other hand, they are not zipped. Usually, they are sealed with a sealing stick, a sealing strip, or a rubber band. Although these bean bags can be sealed with tools, the fresh-keeping effect is not as good as chain bags, so coffee beans usually do not stay fresh for a long time.

4. Small bean bag

This bag can come in many sizes, but it is usually used to fill coffee beans in a single cup. If the bean baker wants to provide samples to customers, he usually uses this kind of bag.

Although these bags are relatively small, they can be printed on the whole side to improve the chances of branding. However, this kind of beanbag needs to be supported by other items to keep standing, so it will be more limited in display.

What are the characteristics of bean bags that should be considered?

When you consider packaging, there are several features to pay attention to:

Loading process

Bags with smaller openings take longer to open and fill than bags with wider openings. Whether you choose to fill the bag manually or use an automatic filling machine, make sure the process and the time it takes.

Exhaust valve

Bean bags without air valves usually expand or even burst. The exhaust valve allows carbon dioxide released from roasted coffee to be discharged from the bean bag. This is an one-way valve: only carbon dioxide is emitted without letting oxygen in. However, please remember that the bean bag needs to be completely sealed to be effective, so the quality of the seal should also be paid attention to.

Tear angle

Very simple design, so that users can open bean bags more quickly

To clip or tie a chain.

In order to keep the coffee fresh, the bag should be re-sealed after opening. The clip chain is a user-friendly design that creates a sealed space. You can also choose to tie the straps, although the straps cannot be sealed, but they are well insulated from oxygen and easy to use.

Manufacturer

When a problem occurs, it is also important to have a reliable manufacturer so that there is no way to ask for help, and the manufacturer can solve the problem.

Sustainability.

Most coffee packages are made of aluminum foil, paper, polyethylene and other thin layers. Because coffee is sensitive to external factors such as oxygen, moisture and ultraviolet rays, the packaging must have an isolation layer, usually three or two layers. However, with the continuous pressure from the public, manufacturers are bound to provide more environmentally friendly design materials.

For example, Corina says MT Pak uses corn starch to make industrial compost bags. The shelf life is about 10-12 months, of course, it is also a kind of food-grade packaging. They are also printable, resistant to oil and ultraviolet rays, and have a material that insulates the loss of aroma.

There are many factors to consider when choosing coffee packaging: cost, operation, durability, display, sustainability, air valve, repeatability, manufacturer, etc. But the most important thing is to understand your own needs and choose the packaging that best suits you.
