Embodiment Construction

[0017] like figure 1 , figure 2 As shown, a tea packaging bag with a multi-layer structure, the tea packaging bag is a layered structure, from the outside to the inside is OPP film 1, PET laser film 2, aluminum foil 3 and PE film 4, the tea packaging bag is composed of each layer Fitted. The inner side of the OPP film 1 is printed with an ink layer 5 .

[0018] PET means polyethylene terephthalate in Chinese. Polyethylene terephthalate is a milky white or light yellow highly crystalline polymer with a smooth and shiny surface. Good creep resistance, fatigue resistance, friction resistance and dimensional stability, low wear and high hardness, with the greatest toughness among thermoplastics; good electrical insulation performance, little affected by temperature. Non-toxic, weather resistance, good stability against chemicals, low water absorption.

[0019] Aluminum foil is a soft metal film, which not only has the advantages of moisture-proof, air-tight, light-shielding, ...

Abstract

The invention discloses a tea packaging bag with a multi-layer structure. The tea packaging bag has a layered structure, and comprises an oriented polypropylene (OPP) film, a polyester (PET) laser film, an aluminum foil and a polyurethane (PE) film from outside to inside; and various layers are attached to one another to form the tea packaging bag. The tea packaging bag has the advantages of the OPP, PET, the aluminum foil and the PE, has a better sealing effect, and ensures a better tea preserving effect and long storage time; and printed ink hardly infiltrates the packaging bag, so that tea is more safe and sanitary.
