Abstract

The invention relates to a packaging material used in drugs and a preparing method thereof. The packaging material is prepared from, by weight, 72-85 parts of polyvinylidine chloride, 18-26 parts of acrylic ester, 20-28 parts of natural rubber, 10-17 parts of polyethylene glycol, 8-13 parts of lignocellulose, 10-16 parts of nano calcium carbonate, 7-13 parts of vermiculite power, 12-17 parts of corn starch, 3-8 parts of acetyl citrate, 5-9 parts of antibacterial agent and 2-6 parts of cellulose acetate; the packaging material used in the drugs use polyvinylidine chloride as a main raw material, has a good effect of obstructing gases in air such as oxygen, vapour, carbon dioxide, has a good damp resistant property, and good transparency and good heat-resistant and cold-resistant properties; the adding of acrylic ester and natural rubber plays a role of plasticizing the internal parts; acetyl citrate is adopted as a plasticizer, thus the packaging material used in the drugs is green and environmentally friendly, and poisonless and tasteless; through the adoption of the antibacterial agent, the packaging material used in the drugs has a strong antimicrobial effect and an enduring bacteria-resistant effect, and thus expiration date of the drugs is prolonged.

Description

technical field [0001] The invention relates to the field of packaging materials, in particular to a packaging material for medicines and a preparation method thereof. Background technique [0002] Drugs are a special kind of commodity, which are easily decomposed and deteriorated due to the influence of light, humidity, microbial pollution and other surrounding environments during the circulation process. stability, delay drug deterioration, and ensure drug safety for the broad masses of the people. Therefore, the packaging of medicines is called the second life of medicines. Unsuitable materials can cause migration, adsorption, and adsorption of active pharmaceutical ingredients, leading to drug failure, and sometimes serious toxic side effects. [0003] With the strengthening of people's awareness of environmental protection, a consensus has been reached on green packaging. Most of the pharmaceutical packaging materials are not degradable and difficult to recycle after ...
