Problems solved by technology

Nevertheless, the aluminum foil used for pharmaceutical packaging still inevitably has the hidden danger of microbial contamination.
In order to further reduce the probability of microbial growth on the surface of the aluminum foil, the purification degree of the production and packaging workshop needs to be further improved, which requires higher costs and maintenance costs

Embodiment Construction

[0015] The present invention will be described in further detail below, so that those skilled in the art can implement it with reference to the description.

[0016] A kind of antibacterial self-cleaning PTP aluminum foil provided by the present invention is implemented through the following specific methods:

[0017] 1) Choose a broad-spectrum, strong and durable antibacterial agent, which is required to withstand the high temperature of coating processing at 200°C.

[0018] Silver-based antibacterial agents are superficially outstanding in terms of antibacterial ability, heat resistance and durability, but the bacterial remains killed by silver-based antibacterial agents can release pyrogenic and toxic components, which can cause diseases such as typhoid fever and cholera. Nano-TiO 2 , ZnO as a photocatalytic antibacterial agent can quickly and effectively decompose the organic matter that constitutes the bacteria, coupled with the synergistic effect of other active oxidizi...

Abstract

The invention provides an antibacterial self-cleaning PTP (Poly Terephthalic acid) aluminum foil. The antibacterial self-cleaning PTP aluminum foil is in a double-layered structure and comprises a base body layer and a nano antibacterial coating, wherein the base body layer is in a sheet layer structure and is composed of hard or soft aluminum foil of 20-30 microns; the nano antibacterial coating is coated on the base body layer and is composed of hot melt glue and a nano antibacterial agent; the nano antibacterial coating contains the nano antibacterial agent with the concentration of 5000PPM (Parts Per Million)-30000PPM, wherein the base body layer and the nano antibacterial coating are compounded to prepare the antibacterial self-cleaning PTP aluminum foil; when the prepared antibacterial self-cleaning PTP aluminum foil is used for packaging medicines, the base body layer is located on the outer side and the nano antibacterial coating is located on the inner side and is directly contacted with the medicines. The invention further discloses a preparation method of the antibacterial self-cleaning PTP aluminum foil; the prepared PTP aluminum foil can effectively prevent secondary pollution on the aluminum foil, caused by production and machining as well as packaging; the prepared PTP aluminum foil also has a certain sterilization function on microorganisms carried on the medicines.

Description

technical field [0001] The invention relates to a medicine packaging material, in particular to a functional PTP aluminum foil and a preparation method thereof. Background technique [0002] my country has strict microbial control standards for pharmaceutical packaging. Among them, YBB10012012 aluminum foil for pharmaceutical packaging stipulates that the microbial limit is as follows: the opening area for the sample to be tested is 20cm 2 Press the sterilized metal template on the inner layer, slightly moisten the sterile cotton swab with sodium chloride injection, wipe it five times within the area of ​​the plate hole, change a cotton swab and wipe it five times again, each position Wipe a total of ten times with two cotton swabs, and wipe a total of five locations 100cm 2 . Cut (or burn) each cotton swab immediately after wiping it, and put it into an Erlenmeyer flask (or large test tube) filled with 30ml of sodium chloride injection. After wiping all the cotton swabs ...
