51mm Keurig Coffee Capsule Filling Coffee Empty K Cup with 2.0 Foil Lid Cut and Welded Filter

Filtered K-Cup supplies are made of food-grade polypropylene (PP) combined with a non-woven material.
The cup and filter are fused together, likely using heat sealing methods, creating a unit with an EVOH
(ethylene vinyl alcohol copolymer) film as a barrier layer.

EVOH is known for its excellent gas barrier properties, particularly in blocking oxygen and other gases.
This feature is highly beneficial in preserving the freshness and quality of coffee by preventing oxidation,
which can affect its taste over time.

The smooth surface of these cups and their superior heat sealing performance help maintain the freshness of the coffee by keeping it sealed and protected from external elements.
This design is compatible with various Keurig coffee brewers, ensuring no damage occurs even under high pressure and temperature conditions during brewing.

Additionally, the specific groove design likely helps prevent water leakage during the brewing process, ensuring a smooth and mess-free experience.

Overall, these features highlight how these K-Cup supplies aim to maintain the quality, freshness, and safety of the brewed coffee while being compatible with Keurig machines for convenient use.
