As a coffee company, you take product excellence seriously. Besides growing, harvesting, and roasting processes, packaging contributes to your product’s quality. Preserving peak freshness calls for thoughtfully chosen packaging. Airtight, resealable, and flexible options ensure that your coffee remains in optimal condition.
It Has To Be Airtight
Oxygen is the number one enemy of coffee. Exposure of whole beans and grounds to the open air results in oxidization. During this process, oxygen steals electrons from other compounds. Coffee loses aroma, flavor, and freshness as a result. Heat worsens these effects: Aroma loss doubles for every 10-degree Celsius increase.
Air exposure also means moisture exposure. Once beans or grounds come in contact with humidity, flavor and aroma loss can worsen. With extreme air moisture, coffee may even become stale or moldy.
Custom coffee bags are an ideal means of protecting your product. With a wide range of sealing options, they can easily maintain quality and freshness. Whether after production, during shipment, in stores, or in your customers’ homes, your coffee keeps more of its original taste and smell. Digital printing creates high-impact designs that grab attention and convey your brand image.
Needs To Be Resealable
Airtightness is only one part of the coffee freshness equation. Resealability is also key. After all, customers want to enjoy its original condition after bringing it home. Resealable packages lock out the air and moisture that ruin your product’s quality.
Resealable closures come in a wide range of styles. Press-to-close zippers are among the most popular. Meanwhile, you can also choose child-resistant versions that resist tampering. Your business goals and needs should dictate which type of closure you choose.
You can pair resealable closures with almost any kind of flexible packaging material. Available choices include polyethylene polymers, post-consumer recycled materials, compostable films, and biaxially-oriented polypropylene. Using them with packs made from high-barrier films prevents moisture and air entry. Gusset bags and stand-up pouches are a couple of popular options. You can also choose printed mylar bags with zippered closures.
The Importance of Degassing Valves
Coffee beans give off carbon dioxide and volatile gasses after roasting. Even well after packaging, coffee can still emit these compounds. It can take several weeks for coffee to finish releasing all the gasses from the roasting process. Without any means to release these gasses, coffee packages can bulge or even burst. Fortunately, there’s a helpful solution to this problem: degassing valves.
Adding a degassing valve to your packaging allows gasses released by your coffee to escape. Because this valve is a one-way passage, carbon dioxide exits the bag without letting in air or water. The valve only opens when the pressure inside the package is higher than the outside. Once pressure releases, the valve closes again. Thanks to this innovation, whole beans, and grounds remain fresh, flavorful, and fragrant.
Proper Storage for Peak Perfection
Growing, harvesting, and roasting are critical parts of coffee production. The right packaging also contributes to freshness, flavor, and fragrance. High-barrier films, resealable closures, and degassing valves are vital to preserving product quality.
