Embodiment 1

[0040] The composition of the raw material formula is shown in Table 1.

[0041] The preparation process of the medical flame-retardant plastic packaging material described in this embodiment includes the following steps:

[0042] (1) Start the air-conditioning unit: make the film blowing area of ​​the production workshop reach Class C, and the bag making area and inner packaging area reach Class B;

[0043] (2) Disinfection of clean area: thorough disinfection according to GMP requirements;

[0044] (3) Air or nitrogen purification: After air or nitrogen is purified, it reaches Class C cleanliness standards;

[0045] (4) Mixing: Mix the formula raw materials evenly;

[0046] (5) Film blowing: control the barrel temperature to 175±3°C, the die temperature to 165±3°C, and the blow-up ratio to 2.0;

[0047] (6) Winding: Winding into film or cutting bags according to requirements, and the heat sealing temperature of cutting bags is 210±3℃.

Embodiment 2

[0049] The composition of the raw material formula is shown in Table 1.

[0050] The preparation process of the pharmaceutical flame-retardant plastic packaging material in this embodiment is the same as that in Example 1, except that in step (5), the temperature of the barrel is controlled to be 185±3°C, and the temperature of the die is 175±3°C. The inflation ratio is 3.0; the heat-sealing temperature in step (6) is 217±3°C.

Embodiment 3

[0052] The composition of the raw material formula is shown in Table 1.

Abstract

The invention relates to a medicinal flame-retardant plastic packaging material and a preparation process thereof, belonging to the technical field of medicinal packaging materials. The medicinal flame-retardant plastic packaging material has a three-layer structure, an inner layer consists of PE, PLA, PHBV and ECO, a middle layer consists of PE, PLA, PHBV and EVA, and the outer layer consists of PE, PLA, PHBV and ECO. According to the preparation process, components are mixed uniformly according to the formula amount, film blowing is implemented by adopting a three-layer film blowing machine, and finally, rolling is implemented to form a film or cutting is implemented to prepare a bag. The degradable components contained in the plastic packaging material can be degraded gradually under the conditions of light, water and microorganisms in a short time to form a large-area hole, so that the mechanical properties of materials can be lowered, and the degradation of the materials can be accelerated; the contained flame-retardant components play the role of synergistic flame retardance, so that the medicinal flame-retardant plastic packaging materials can be applied to medicine packaging, particularly the packaging of medicines which are directly contacted, and the medicinal flame-retardant plastic packaging material provides a good, excellent and safe selection for the production and packaging of medicines.

Description

Technical field [0001] The invention relates to a medical flame-retardant plastic packaging material and a preparation process thereof, and belongs to the technical field of medical packaging materials. Background technique [0002] Polyethylene (PE) plastic has the advantages of low density, high strength, corrosion resistance, non-toxicity, excellent dielectric properties, good chemical stability, corrosion resistance, low price, and easy molding and processing. It is widely used in chemical, Food, medicine and other industries. However, because the garbage produced by polyethylene plastic is not easily degraded, it will destroy the natural environment in the process of landfill and incineration, causing great harm to the environment, and also posing a serious threat to the survival of humans and various organisms. With the strengthening of human environmental protection awareness, various degradable plastics continue to appear. Degradable plastics can decompose by themselves ...
