Embodiment 1

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

[0041] The preparation process of the medicinal flame-retardant plastic packaging material described in the present embodiment, the steps are as follows:

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

[0043] (2) Disinfection in clean area: thoroughly disinfect according to GMP requirements;

[0044] (3) Air or nitrogen purification: after the air or nitrogen is purified, it reaches the C-level cleanliness standard;

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

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

[0047] (6) Winding: According to the requirements, it can be wound into film or cut into bags respectively. The heat sea...

Embodiment 2

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

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

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 medicinal flame-retardant plastic packaging material and a preparation process thereof, belonging to the technical field of medicinal packaging materials. Background technique [0002] Polyethylene (PE) plastic is widely used in chemical industry, Food, pharmaceutical and other industries. However, because the garbage produced by polyethylene plastic is not easy to be degraded, it will destroy the natural environment in the process of landfill and incineration, causing great harm to the environment, and at the same time, it also poses a serious threat to the survival of human beings and various organisms. With the strengthening of human awareness of environmental protection, various degradable plastics continue to appear. Under the action of the biological environment, degradable plastics can decompose by themselves, and are harmless to humans and the environment. They are environmentally friendly green packaging materials. ...
