Abstract

The invention discloses a kind of preparation method of acceptable packaging material, comprise the following steps：(1) melting is heated after mixing medicine or food-grade polyvinylidene chloride (PVDC), ethylene propylene copolymer, thereafter carboxymethylcellulose calcium is added, gypsum is added after being well mixed to three, carry out high shear agitation, stir speed (S.S.) is reduced again, polyvinylpyrrolidone and dibutyl hydroxy toluene are added, uniform and natural cooling is again stirring for, pre-composition is obtained；(2) pre-composition that step (1) is obtained is coextruded with metallocene PE, is shaped to membranaceous；(3) film layer for obtaining step (2) is combined by tack coat with aluminium foil layer, that is, obtain the acceptable packaging material.Packaging material property obtained in of the invention is homogeneous, stabilization, and the wet, choke of resistance, oxidation proof propertiess are excellent, and medicine can be deposited under hygrothermal environment for a long time, while the good processability of packaging, is molded difficulty low.

Description

A kind of preparation method of acceptable packaging material
Technical field
The present invention relates to the technical field of acceptable packaging material, the technical field of more particularly to aluminum-plastic packaged material.
Background technology
Aluminium-plastic bubble plate packing is widely used in the packaging of medicine tablet, capsule, and this based packaging material leads in the prior art It is commonly present barrier property not good enough, particularly hinders that wet, gas barrier properties are not ideal, causes medicine to occur rotten showing in storage As.
The content of the invention
It is a kind of with the acceptable packaging material for efficiently hindering wet, choke, oxidation proof propertiess it is an object of the invention to propose Preparation method.
Technical scheme is as follows：
A kind of preparation method of acceptable packaging material, comprises the following steps：
(1) melting is heated after mixing medicine or food-grade polyvinylidene chloride (PVDC), ethylene-propylene copolymer, and Carboxymethylcellulose calcium is added under stirring, it is well mixed to three, gypsum is added in its backward fused mass, cut at a high speed Stirring is cut, then reduces stir speed (S.S.), to polyvinylpyrrolidone and dibutyl hydroxy toluene is added in mixture, be again stirring for Even and natural cooling, obtains pre-composition；
(2) pre-composition that step (1) is obtained is coextruded with metallocene PE, is shaped to membranaceous；
(3) film layer for obtaining step (2) is combined by tack coat with aluminium foil layer, that is, obtain the acceptable packaging material.
Preferably：The pre-composition in parts by mass, including 15~20 parts of polyvinylidene chloride, ethylene-propylene copolymer 3~5 parts of thing, 1~1.5 part of carboxymethylcellulose calcium, 0.8~1.2 part of polyvinylpyrrolidone, dibutyl hydroxy toluene 0.1~0.3 Part, 0.5~1 part of gypsum.
It is also preferred that：In parts by mass, the pre-composition in parts by mass, including gathers inclined two chloroethene to the pre-composition 15 parts of alkene, 3 parts of ethylene-propylene copolymer, 1.2 parts of carboxymethylcellulose calcium, 1.0 parts of polyvinylpyrrolidone, butylated hydroxy-a 0.2 part of benzene, 0.8 part of gypsum.
Obtained packaging material property of the invention is homogeneous, stabilization, can be used for the packaging of the formulations such as tablet, pill, capsule, hinders Wet, choke, oxidation proof propertiess are excellent, and medicine can be deposited under hygrothermal environment for a long time, while the good processability of packaging, shaping hardly possible Degree is low.
