Abstract

The invention discloses a producing method for medicinal polyethylene bottles. Medium density polyethylene 3505 occupies 60%, high density polyethylene 7000F occupies 20%, and high density polyethylene 5000S occupies 20%. The producing method comprises the following producing steps: firstly designing an appearance and a volume of the polyethylene (PE) bottle according to a requirement of a user; manufacturing a mould and installing the mould into a hollow bottle blowing machine; putting a PE raw material into a feeding hopper, heating and plastifying the PE raw material through a gun barrel, forming in the mould and demoulding after cooling; removing leftover materials and checking a product. The medicinal polyethylene bottles disclosed by the invention have the advantages of good sealing performance, excellent dropping resistance and compressive resistance and the like.

Description

technical field [0001] The invention relates to the field of hygienic production, in particular to a production method of a medicinal polyethylene bottle. Background technique [0002] In the past 10 years, my country's pharmaceutical plastic containers have developed rapidly. To a considerable extent, this development is the product of the combination of GMP transformation and the entry of high-quality pharmaceutical plastic containers into our country. On the one hand, it proves the inevitability of the development of pharmaceutical plastic containers, and on the other hand, it also exposes the problems in the development of pharmaceutical plastic containers. The permeability and moisture resistance are not strong, resulting in oxidative discoloration and deterioration of the contents. Contents of the invention [0003] In order to overcome the above-mentioned shortcomings of the prior art, the object of the present invention is to provide a method for producing a phar...
