Problems solved by technology

[0003] However, both paper tube wax-soaked packaging and spherical shell packaging have packaging defects such as light protection and poor sealing. Chinese medicine honeyed pills often harden, especially when honeyed pills contain volatile precious medicinal materials. There will be a problem of reduced efficacy
[0004] The existing aluminum-plastic blister packaging system is composed of outer layer nylon, middle layer aluminum foil, inner layer polyvinyl chloride (PVC) cold stamping composite sheet and medicinal aluminum foil. 6-9mm, the maximum value of the test does not exceed 12mm, due to the limitation of the cupping value of the blister, it can only be used for the packaging of capsules and tablets, and cannot meet the packaging requirements of various specifications of honeyed pills
[0005] For common specifications such as and For honeyed pill preparations, there is currently a lack of suitable packaging sheets

[0037] Embodiment 1: Preparation of the inner layer of the composite sheet of the present invention

Embodiment 1-1

[0038] Example 1-1: Preparation of PA co.PE co-extrusion composite film

[0039] raw material:

[0040] Polyamide (PA, produced by DSM in the Netherlands, using the brand name PA6-F136-E2);

[0041] Adhesive resin for co-extrusion of maleic anhydride grafted linear low density polyethylene (produced by Lyondell-Basell, using brand LLDPE 3060);

[0042] Linear low density polyethylene (LLDPE, produced by DuPont Dow, DOWLEX TM 2045G).

[0043] Preparation:

[0044] A three-layer co-extrusion film blowing unit is used. The unit is equipped with three extruders. The three raw materials are converted into weight ratios according to the design thickness of the finished film, and are automatically supplied to the silos of each extruder. Each extruder will be different The raw materials are heated and melt-extruded to the co-extrusion die head. The melt-extrusion temperature of PA6-F136-E2 is 250℃~280℃. LLDPE 3060 melt extrusion temperature is 230℃~260℃, DOWLEX TM The melt ...

Abstract

The invention provides a composite sheet for medicine packaging and a Chinese herbal honeyed pill wrappage prepared from the composite sheet. The composite sheet is suitable for cold stamping formingand comprises an outer layer, a middle layer and an inner layer, wherein the outer layer is a polyamide film, the middle layer is an aluminum foil, the inner layer is a heat sealing layer, and the inner layer is composed of a co-extruded composite film formed by the same or different resins. The composite sheet is large in breaking force, high in cupping test value, high in heat sealing strength,high in peel strength and excellent in barrier properties, and is particularly suitable for preparing Chinese herbal honeyed pill wrappages.

Description

technical field [0001] The invention relates to the technical field of medicine packaging sheets, in particular to provide a composite sheet suitable for cold stamping for packaging honeyed pills of traditional Chinese medicine. Background technique [0002] Traditional Chinese medicine honeyed pills are one of the main dosage forms of traditional Chinese medicine. There are generally two packaging methods: (1) paper tubes soaked in wax. After buckling, labeling, and finally sealing with wax; (2) spherical shell packaging, which is divided into two types: wax shell and plastic shell. The wax shell is made by placing unpacked large honey pills in centrifugal pouring It is packaged in a wax shell, and the plastic shell is divided into bare pills and large honeyed pills wrapped in paper and put into a hemispherical spherical shell, and then sealed with wax after buckling. [0003] However, both paper tube wax-soaked packaging and spherical shell packaging have packaging defect...
