Do you drink coffee often? Do you enjoy coffee? Have you ever noticed the packaging? Coffee packaging typically uses pure aluminum foil materials in multi-layer composite structures. Do you know why? Today, Shenzhen packaging bag manufacturers will analyze why pure aluminum materials are frequently used in coffee packaging bags.
First, let's understand the properties of pure aluminum. It offers advantages like lightweight construction, excellent sealing, and superior wrapping capabilities. Aluminum foil can be printed with various patterns, designs, text, or images on its surface, available in single colors or up to 12 different hues.
Second, let's consider coffee itself. As an aromatic product, coffee requires excellent sealing to preserve its flavor. Pure aluminum's sealing properties effectively protect coffee's original taste, preventing loss of aroma, moisture absorption, and exposure to light.
Third, aluminum foil is colorless, odorless, and non-toxic, making it safe for direct food contact. This makes it the ideal choice for packaging coffee powder and beans.
Depending on customer requirements, coffee foil bags come in various styles: three-side sealed, stand-up pouches, and center-sealed gusseted pouches. In recent years, octagonal-sealed bags have gained significant popularity among consumers. Octagonal-sealed coffee foil bags have become prevalent. To accommodate user preferences, side-sealed zippers are often added, creating octagonal-sealed zipper coffee foil bags. Depending on storage conditions, one-way vent valves may be incorporated, making one-way vent coffee foil bags the most widely used in coffee packaging.
This explains why pure aluminum materials are predominantly used for coffee packaging bags. However, to reduce costs, metalized materials may be employed depending on specific requirements.
