Problems solved by technology

[0003] However, there are still many defects in the existing paper cups; for example, the anti-seepage performance of the coating layer of the inner layer of the paper cup is not very reliable, especially when boiling water or hot drinks are in full bloom, water leakage is easy to occur. Appears softening phenomenon, difficult to use

Abstract

The invention relates to the technical field of paper cups, in particular to a novel anti-seepage paper cup. The novel anti-seepage paper cup comprises a paper cup body, wherein the paper cup body comprises a first waterproof layer, a first heat insulation layer, a first reinforcing layer, a fan-shaped paper sheet, a second reinforcing layer, a second heat insulation layer, a second waterproof layer and a printing layer, wherein the first reinforcing layer and the second reinforcing layer are formed by a high molecular layer formed by bonding two layers of high molecular materials and fabric layers evenly arranged in the high molecular layer; each fabric layer is formed by weaving warp yarns and weft yarns; the warp yarns are cotton fibers; the weft yarns are blended by polylactic acid fiber yarns and the cotton fibers; the high molecular layer is a thermoplastic polyurethane resin film; and a 2-3 mm lamination reverse fold is reserved at the side surface bonding position of the fan-shaped paper sheet. The paper cup has the advantages of guaranteeing sanitation, and being excellent in water seepage prevention performance, good in heat insulation performance and high in strength.

Description

technical field [0001] The invention relates to the technical field of paper cups, in particular to a novel anti-seepage paper cup. Background technique [0002] With the rapid development of social economy, a large number of various paper products have entered people's living space; among them, the application of paper cups is quite common. [0003] However, there are still many defects in the existing paper cups; for example: the anti-seepage performance of the coating film layer of the inner layer of the paper cup is not very reliable, especially when boiling water or hot drinks are in full bloom, water leakage is easy to occur, and at the same time, the paper cup is prone to leakage after water seepage. Softening occurs, making it difficult to use. [0004] For this reason, propose a kind of novel anti-seepage paper cup. Contents of the invention [0005] The purpose of the present invention is to provide a new anti-seepage paper cup, which has the characteristics of...
