Embodiment 1

[0014] A production method of a medicinal plastic bag, wherein: raw materials and their percentages are as follows: polyethylene 5000S 50%;

[0015] Low density polyethylene 2426H 25%;

[0016] Metallocene linear polyethylene 3505HH 25%.

[0017] The production method steps are as follows:

[0018] 1) Feed polyethylene 5000S, low-density polyethylene 2426H and metallocene linear polyethylene 3505HH into the mixer according to the above ratio, and mix them uniformly at a temperature of 180°C to form a blank; then put the blank into a plastic granulator , plasticized and cut out particles at a temperature of 180°C;

[0019] 2) Throw the particles into the hopper of the film blowing machine, heat up to 180°C and extrude the film;

[0020] 3) Put the film into a sealing and cutting machine to seal and cut into medical plastic bags.

Embodiment 2

[0022] A production method of a medicinal plastic bag, wherein: raw materials and their percentages are as follows: polyethylene 5000S 50%;

[0023] Low density polyethylene 2426H 25%;

[0024] Metallocene linear polyethylene 3505HH 25%.

[0025] The production method steps are as follows:

[0026] 1) Feed polyethylene 5000S, low-density polyethylene 2426H and metallocene linear polyethylene 3505HH into the mixer according to the above ratio, and mix them uniformly at a temperature of 200°C to form a blank; then put the blank into a plastic granulator , plasticized and cut out particles at a temperature of 300°C;

[0027] 2) Throw the particles into the hopper of the film blowing machine, heat up to 230°C and extrude the film;

[0028] 3) Put the film into a sealing and cutting machine to seal and cut into medical plastic bags.

Embodiment 3

[0030] A production method of a medicinal plastic bag, wherein: raw materials and their percentages are as follows: polyethylene 5000S 50%;

[0031] Low density polyethylene 2426H 25%;

[0032] Metallocene linear polyethylene 3505HH 25%.

[0033] The production method steps are as follows:

[0034] 1) Feed polyethylene 5000S, low-density polyethylene 2426H and metallocene linear polyethylene 3505HH into the mixer according to the above ratio, and mix them uniformly at a temperature of 1900°C to form a blank; then put the blank into a plastic granulator , plasticized and cut out particles at a temperature of 250°C;

[0035] 2) Throw the particles into the hopper of the film blowing machine, heat up to 200°C and extrude the film;

[0036] 3) Put the film into a sealing and cutting machine to seal and cut into medical plastic bags.

[0037] According to the following table 1 of the medical plastic bag detection result that above-mentioned embodiment one to three produces:

Abstract

The invention discloses a production method of a medicinal plastic bag. Polyethylene 5000S, PE2426H and PE3505 are fed into a blender mixer to be mixed in proportion of 50%, 25% and 25% and then fed into a grain pulling machine for high-temperature plasticizing, particles are cut out, the particles are fed into a hopper of a film blowing machine, heated extrusion is performed to fabricate a film, and the film is sealed and cut into the bag in the length direction. The medicinal plastic bag has the advantages of being high in transparency, resistant to water, good in steam permeability, capable of performing efficient sterilization and blocking germs and the like.

Description

technical field [0001] The invention relates to the field of hygienic packaging, in particular to a production method of a medicinal plastic bag. Background technique [0002] Due to its excellent low temperature resistance, good chemical stability and electrical insulation properties, pharmaceutical bags are widely used in the transfer and temporary storage of raw drug powders, food powders, and chemical powders. In the pharmaceutical industry, direct contact with pharmaceuticals High-quality packaging materials and containers are an integral part of drug quality, accompanying the entire process of drug production, distribution and use, and play an important role in ensuring drug safety. As the safety and quality standards of drugs produced by modern pharmaceutical factories are getting higher and higher, the original formula of outer packaging materials for dialysis and infusion can no longer meet the requirements of users. Contents of the invention [0003] In order to...
