[0015] The technical solutions in the embodiments of this utility model will be clearly and completely described below. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0016] Please see Figures 1 to 3 A tea packaging cup with good barrier properties includes a cup-shaped body 1, which is made of a composite material sheet with barrier properties, pressed and molded. The thickness of the composite material sheet is approximately 0.5-1.5 mm. The composite material sheet includes at least one EVOH layer 2, which is made of ethylene-vinyl alcohol copolymer. The EVOH layer 2 has good barrier properties against external moisture. PP plastic layers 3 are respectively disposed on both sides of the EVOH layer 2, which also have a certain barrier properties against external moisture and foreign objects. An adhesive layer 4 is disposed between the EVOH layer 2 and the PP plastic layer 3 to bond the EVOH layer 2 and the PP plastic layer 3 together. The PP plastic layer 3 is bonded to the EVOH layer using a blown film process.

[0017] Preferably, the adhesive layer 4 is a polymer adhesive attached between the EVOH layer 2 and the PP plastic layer 3, so that the EVOH layer 2 and the PP plastic layer 3 are tightly bonded together.

[0018] Preferred, such as Figure 3 As shown, the composite material sheet includes two EVOH layers 2, with a PP plastic layer 3 disposed between the two EVOH layers 2. An adhesive layer 4 is disposed between the PP plastic layer 3 and the adjacent EVOH layer 2. A PP plastic layer 3 is disposed on the outer side of each of the two EVOH layers 2, and an adhesive layer 4 is disposed between the outer PP plastic layer 3 and the EVOH layer 2. The multi-layered composite material sheet is pressed into the cup body using a molding die. PP plastic is environmentally friendly and healthy.

[0019] Preferably, a reinforcing layer 5 is provided on the outer side of the PP plastic layer 3 outside the EVOH layer 2. The reinforcing layer 5 is a homopolymer PP plastic layer, which is formed by pressing homopolymer PP plastic and has stronger strength than low-density PP plastic, thereby increasing the strength and hardness of the composite material sheet.

[0020] Preferably, a printing layer 6 is provided on the outer side of the reinforcing layer 5, on which corresponding patterns or text can be printed. The printing layer 6 is made of homopolymer PP plastic.

[0021] Preferably, an antibacterial layer 7 is provided at the innermost layer of the cup body 1. The antibacterial layer 7 is an antibacterial PP plastic layer, and macromolecular antibacterial groups are added to the antibacterial PP plastic layer. The macromolecular antibacterial groups have bactericidal function and can remove some harmful bacteria in the packaging. Generally, antibacterial masterbatch is crushed and added to the PP plastic film. The antibacterial masterbatch contains the antibacterial active substance polyhexamethylene guanidine hydrochloride, which can kill harmful bacteria such as Escherichia coli and Staphylococcus aureus, thus protecting the tea from bacterial contamination during storage.

[0022] When using this utility model of a tea packaging cup with good barrier properties, tea leaves are placed inside the packaging cup, and then the top of the cup is sealed with a top cover with good barrier properties. Because the EVOH layer in the composite material sheet has excellent barrier properties against external moisture, the double EVOH layer of the packaging cup 1 provides even better barrier properties against external moisture. Combined with the antibacterial properties of the antibacterial layer, the tea leaves can be stored well inside the packaging cup 1 without mold or other deterioration. The packaging cup made of this multi-layered composite material sheet is very suitable for packaging and storing tea leaves, and is also suitable for use in dedicated tea brewing devices.

[0023] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made using the content of this utility model specification, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
