Selection Of Coffee Bags And Differences In The Freshness Of Coffee

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

Do you drink coffee every day? Do you know where the coffee you drink comes from?

Standing coffee bags are common in the market, and this kind of coffee bag is characterized by being cheaper than other kinds.

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

The bottom corner also allows the bag to stand, giving more room for coffee beans to show. If you add more design, you can make a bag of coffee beans more attractive.

The bean roaster can easily fill the coffee beans into this bag because the opening of the coffee bag is large, which makes the packaging operation more efficient and smooth.

The appearance of this coffee bag is very beautiful. The square bottom design makes the coffee bag stand more stable and its presentation more prominent. According to different materials, it can have a deeper and modern design sense. If the design of the chain clip bag is used, the appearance and functionality (repeatable sealing) coexist at the same time.

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

In addition, this kind of coffee bag will be more ideal if it is equipped with a ventilation valve. The coffee can exhaust and age in a normal time course, which is also the main function of the air valve. In addition, the clip chain allows users to use a small amount of coffee beans and then reseal the coffee bag to keep it fresh.

The disadvantage of this coffee bag is that the manufacturing process is complex, so its price is usually high.

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

These coffee bags can be printed at various angles, making them easy to brand, and they are also cheaper than other coffee bags. On the other hand, they don't have zippers. Usually, they are sealed with sealing rods, sealing strips, or rubber bands. Although the coffee bag can be sealed with tools, the preservation effect is not as good as the chain bag, so the coffee beans usually do not stay fresh for a long time.

This bag can come in many sizes, but it is usually used to fill a single cup of coffee beans. This bag is usually used if the bean roaster wants to provide samples to customers.

Although these bags are relatively small, they can be printed on the whole face to enhance the opportunity for branding. However, this coffee bag needs to be supported by other items to keep standing, which will be limited in the display.

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, ensure the process and the time it takes.

Coffee bags without air valves usually swell or even burst. The exhaust valve allows the carbon dioxide released by the roasted coffee to be discharged from the coffee bag. This is a one-way valve: it only discharges carbon dioxide but does not let oxygen in. However, please remember that the coffee bag needs to be completely sealed to be effective, so pay attention to sealing quality.

Do you brew coffee at home? Do you use pre-roasted coffee or freshly roasted coffee beans?

Most coffee packages are made of aluminum foil, paper, polyethylene, and other thin layers. Since coffee is very sensitive to external factors such as oxygen, moisture, and ultraviolet light, the packaging must have an isolation layer, usually 3 or 2 layers. However, with the increasing pressure from the public, it is necessary for manufacturers to provide more environmentally friendly design materials.

The shelf life is about 10-12 months. Of course, it is also food grade packaging. They are also printable, resistant to oil and ultraviolet rays, and have materials that block the loss of aroma.

Many factors need to be considered 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 most suitable packaging for you.
