Embodiment 1
[0025] A biodegradable barrier pharmaceutical packaging bottle, which is prepared from the following raw materials in parts by weight: poly-β-hydroxybutyrate 150, barium stearate 30, talc powder 10, zeolite powder 10, corn starch 15. Methylcellulose 20, polylactic acid 30, glycerin 20, ethylene glycol 10, Gly-Thr-Gly-Gly short peptide 8 and polyglycolic acid 6.
[0026] The preparation method of above-mentioned packing bottle, comprises the steps:
[0027] First put the raw materials into the reaction tank in turn, and stir while adding the raw materials. After stirring evenly, enter the twin-screw extruder with a length-to-diameter ratio of 40:1 to extrude into a molten state. The temperature is controlled at 200 degrees Celsius, and then the injection machine is used to inject The molten body is quickly injected into the mold, and the mold is closed and cooled to shape; after the mold is opened, the finished product enters the auxiliary mold, and the side is cut and edged by...

Embodiment 3
[0035] The performance test parameters of the packaging bottle prepared by the present invention are shown in the following table 1, with the 20um thickness prepared in Example 1, the bottom diameter is an example of the packaging bottle of 8cm:
[0036] Table 1
[0037] performance parameters value Exterior Uniform color, no impurities Tensile strength (Mpa) greater than 100 Oxygen throughput (cm3 / m2.24h.0.1Mpa) less than 0.01 Compressive strength (kg / cm2) more than 1kg Intradermal irritation test none Water vapor transmission rate (g / m2.24h) less than 0.01 Biodegradation rate (the amount of carbon dioxide released after composting for 90 days, ISO14885 standard) 98% Hemolysis test Hemolysis rate is less than 1% Allergic reaction Less than I degree
[0038] Conclusion: Through the performance test, it can be found that the degradable performance of the packaging bottle prepare...
