Description

technical field

[0001] The invention relates to the technical field of packaging materials, more specifically, it relates to a fully biodegradable high-barrier sheet used for coffee capsule cups and a preparation method thereof. Background technique

[0002] The English name of the coffee capsule is coffee capsule, which is similar to the medicinal capsule. It is filled with coffee powder in the cup of the coffee capsule. Because the texture of the cup of the coffee capsule is relatively hard, it can maintain the prototype well under high temperature, so it can The high-pressure steam is injected into the capsule, so that the coffee is completely separated under the action of pressure, with coffee crema, full-bodied espresso. Existing coffee capsules are generally made of a plastic cup body and an aluminum foil cover film. In order to ensure that the coffee capsule can still maintain the prototype at high temperature, the cup body of the existing coffee capsule is usually ma...
