Recently, many customers have asked me: "What exactly is your coffee powder packaging machine capable of? Customers in the south always complain about caking in coffee cans during the rainy season. Can this problem be solved?" This question hits the nail on the head! Today, I will talk to you about our unique moisture-proof skills.
When it comes to coffee powder getting damp, our factory's R&D department has put a lot of effort. Two years ago, I went to Hainan to participate in an industry exhibition and saw with my own eyes that "coffee cakes" formed in the sample cans of local distributors. At that time, I was very excited. After we came back, we set up a special task force to test 18 kinds of packaging materials on the market one by one, and finally developed a double-layer humidity barrier technology. Guess what? Now the samples packaged by our coffee powder packaging machine are placed in a simulated environment with a humidity of 85% for 30 days, and you can still smell the mellow aroma of freshly ground coffee when you open the can.
The core of this moisture-proof packaging solution is our specially made composite film material. Don't underestimate this film, there are three layers of secrets hidden inside: the outer layer is scratch-resistant food-grade PET, the middle is sandwiched with moisture-proof aluminum foil, and the innermost layer is protected by a heat-sealable PE film. This set of "iron triangle" combination punches, let alone water vapor, even the oxygen permeability is 60% lower than that of ordinary packaging. Just last week, the production line of the coffee farm in Yunnan was upgraded. The technical director used a thermal imager to detect the sealing temperature on site and praised the temperature control accuracy of our machine.
Speaking of the signature skills of the coffee powder packaging machine, the intelligent nitrogen filling system has to be mentioned. You may not know that coffee powder is most afraid of not only moisture, but also oxidation and deterioration. Our engineers installed a dynamic gas replacement device on the equipment, which automatically replaced nitrogen three times during the packaging process, and the residual oxygen content can be controlled below 1%. Last month, a comparative test by a Qingdao customer showed that the flavor retention period of drip coffee packaged with our equipment was extended by a full four months compared with conventional packaging.
Customers often ask: "Will moisture-proof packaging affect the efficiency of packaging?" We have been prepared for this. The new generation of coffee powder packaging machines adopts a modular design, which can quickly switch from 200 grams of family packaging to 5 kilograms of catering special packaging. Look at the Internet celebrity coffee brand in Zhejiang, which makes small bags for retail packaging during the day and switches to large packaging for B-end customers at night, without stopping the production line. What we are most proud of is the intelligent exhaust valve that can "breathe". It can not only discharge excess gas in the package, but also block external moisture in one direction. This patented design is unique to our factory.
Recently, the factory has received several overseas orders, and customers in the Middle East specifically asked for a customized moisture-proof coffee powder packaging line. To know the tricks of this trade, the key is to have strong equipment. Our coffee powder packaging machines have tackled many tough problems over the years, from low-pressure environments on the plateau to high-humidity climates on the islands. Wherever the equipment goes, the moisture-proof solution follows. Next time you encounter the trouble of coffee powder clumping, feel free to call us, our factory engineers are waiting with solutions!
