What Are Coffee Mylar Bags?

Coffee Mylar Bags are multilayered packaging for cost-effective shipments because of their lightweight and space friendly shape. Use of Coffee Mylar bags is increasing for preserving coffee due to their material and shape. These are high-barrier flexible pouches made of multiple-layer laminations. Mylar coffee bags are usually made up of three layers: 

  • The first layer is made of polyethylene films or kraft papers, best for customization and graphics.  

  • Then comes an aluminum or metallic foil that works as a barrier from moisture, air, and light.

  • The inner layer has a thin layer of Linear low density polyethylene, which is FDA authorized and harmless for coffee.

Mylar bags with watertight seal zippers prevent coffee from losing its flavor and allow it to be reused repeatedly.

A few natural elements, like moisture or light and oxygen are harmful to the coffee beans. Coffee Mylar bags are made of multiple layers that work as a barrier against these external factors. Poly films in outer layers do not let air and light come in. 

Metallic or aluminum foils in the middle block gas exchange between coffee and the external environment, which helps in retaining coffee aroma. Some Mylar bags for coffee beans contain a one-way valve, or we can say a degassing valve. When freshly roasted coffee beans emit carbon, the valves let gas release without absorbing oxygen. 

Why Are Brands Choosing Mylar Bags Over Jars?

Though jars are made of strong packaging material, they are not foldable and do not have airtight seals to keep the coffee fresh. On the other hand, Mylar bags are affordable and lightweight packaging that can be folded and take up less space.  

Moreover, Mylar bags can be customized very easily to increase brand recognition. The poly or kraft outer layer of coffee bags offers a big ground for designing. A well-designed custom coffee Mylar bag works as a mobile advertisement. 

If you add QR scanners or social handles, your customers can directly reach out to you. Custom coffee Mylar bags are the easiest and cheapest way to increase your sales. Mylar pouches are being used as coffee preserving packaging with a market value of $872.9 million in 2024 and expected to reach $1674. 5 million by 2035. These figures clearly show why brands are choosing coffee in Mylar bags for packaging over other options.
