Abstract

A high-barrier PVC medicinal package film and a production process thereof. The invention relates to the field of package materials. The package film includes, by mass, 100 parts of PVC resin powder, 1.0-2.5 parts of a stabilizer, 0.5-1.5 parts of an internal lubricant, 0.2-1.0 part of an external lubricant, 1.0-4.0 parts of a processing aid, 3.0-9.0 parts of MBS resin, and 0.1-3.0 parts of graphene. The PVC medicinal package film, compared with the prior art, has uniform thickness, high surface glossiness and high barrier property. The package film is reduced in water vapor permeation quantity from about 1-2 g / m<2>*24 h to 0.5-1 g / m<2>*24 h; and is reduced in oxygen permeation quantity from 14-18 g / m<2>*24 h * 0.1 MPa to within 3 g / m<2>*24 h * 0.1 MPa.

Description

technical field [0001] The invention relates to the field of pharmaceutical packaging materials, in particular to a high-barrier PVC pharmaceutical packaging film and a production process thereof. Background technique [0002] At present, the most commonly used PTP pharmaceutical packaging film packaging is made of PVC as the base material. PVC has low cost and excellent comprehensive performance. [0003] However, some drugs are very sensitive to humidity and oxygen in actual use, and the barrier properties of existing PVC can no longer meet the needs. Contents of the invention [0004] The object of the present invention is to provide a high-barrier PVC pharmaceutical packaging film and its production process, which has the advantages of simple process, strong corrosion resistance, light product quality and high barrier performance. [0005] The technical solution for achieving the above purpose is: a high-barrier PVC pharmaceutical packaging film, which is characterize...
