Coffee Industry

In coffee packaging, plastic bags are often made from a composite of PE and aluminum foil. This combination effectively blocks oxygen and moisture, and is often equipped with a one-way valve to release gases generated during roasting, preventing the bag from bursting and preserving the fresh flavor of the beans.

Instant coffee is primarily packaged in individual PE bags. This type of packaging is lightweight and portable, shielding against external contaminants. It's ideal for single-serving coffee, making it convenient for consumers to grab and go at home, at work, or on the go, satisfying their instant brewing needs.

Some coffee powder packaging uses a PET/PE composite plastic bag. The transparency of the PET material allows consumers to visually inspect the condition of the coffee powder, while the PE layer ensures a basic seal, facilitating both coffee powder storage and product display.
