Medical packaging materials include those used to package pharmaceutical products or used to package medical devices to simulate packaging materials: packaging materials that can be taken, exposed to pharmaceuticals, or used as functional (such as moisture-proof, barrier, etc.) packaging. Due to the development of polymer materials, plastic packaging materials occupy more and more major positions in medical packaging materials.
Can take medicine packaging materials; such packaging materials are mainly capsules, microcapsules and accessories. Commonly used food starch, gelatin, ethyl cellulose, polyvinyl alcohol and the like. Traditional packaging materials: such as wax, glass, ceramics, paper (board), metal and so on. Plastic packaging materials: occupying more and more important positions in medical packaging materials. As plastic packaging materials, plastics have many excellent characteristics such as high strength, good barrier properties, light weight, easy to carry, transparent, etc., thus becoming the main material in modern medical packaging. , Whether it is pharmaceutical or medical equipment packaging. In the packaging of pharmaceuticals, in addition to various plastic bags (including blood transfusion bags, etc.), plastic bottles, etc., it should be emphasized that the blister pack of tablets is a new type of packaging developed through the use of plastics, which solves It takes a few tablets to take a few tablets and after access it often affects the problem of keeping other unused tablets. Synthetic paper made of plastic can be used to block bacteria penetration and provide conditions for the realization of sterile paper packaging.
1. Medical plastic bottle. It is made of plastics that meet the requirements of medical and sanitary requirements; the types of plastics in practical use are: polyethylene (PE), polypropylene (PP), polystyrene (PS), and polyester (PET). Polyethylene is classified into high-density (HDPE, 0.92-0.93 g/cm3), etc. Polyethylene is used not only for making bottles but also for making caps. Polypropylene has multiple grades and is a different copolymer modification product. Polystyrene has no melting point and is pure and brittle, so there are also many modified varieties, such as high impact polystyrene (HIPS).
PET is a material that has entered medical plastic bottles in recent years. It is characterized by its high transparency, ability to see whether or not the drugs are deteriorating, and is particularly excellent in barrier properties against moisture. This greatly facilitates the preservation of medicines; it is easy to color or add some additives to meet specific requirements. (UV resistance). To improve the oxygen barrier. For copolymerization modification; such as the addition of phthalic acid.
2. Films, composite films. Small bags are usually made for pharmaceutical packaging applications. Plasma bagging is the most typical example of pharmaceutical packaging of composite films. According to the pharmaceutical industry standard YY0236-1996 "Diaphragm for pharmaceutical packaging (General rule)", the film and composite film used for pharmaceutical packaging are: Breathable film has its important position in the application of bone-type drugs. One of the methods for producing a gas permeable film is to add a salt to the film forming material and wash out the salt after the film is formed.
3. Sheets and pills bubble wrap. It is a new technology and new phase of pharmaceutical packaging. The main materials used are aluminum foils, adhesives, and plastic sheets; and plastic sheets and mainly polyvinyl chloride (PVC) sheets and polyester (PET) sheets. Two kinds.
Polyvinyl chloride (PVC) sheets require a non-toxic formulation; PVC resin contains <1X10-6 oxyethylene (VC) content. Polyester (PET) sheet is a sheet used for pharmaceutical packaging after PVC sheet, and after some countries in Europe banned PVC from being used for one-time packaging, it has become the main sheet for pharmaceutical packaging. PET sheet is made of PET or aPET resin; dried → extruded → cast cast. Polyester (PET) sheet resins are used in addition to medical packaging.
4. Synthetic paper, non-woven synthetic paper, and non-woven fabrics (including spunbonded fabrics) can breathe; but medical packaging materials are usually made of mesh holes that cannot be traversed by bacteria; they have the function of blocking bacteria and are used to make surgical instruments. Packaging bags, pastes, pharmaceutical packaging, adhesive tapes, bandages, etc.
Synthetic paper used in medical packaging materials. Non-woven fabrics are more often manufactured by thermal bonding; this avoids the problems associated with the use of adhesives (such as skin allergies). The fiber materials used in the thermal bonding method mainly include main fibers such as polyethylene fibers, polypropylene fibers, and polyester fibers. Also need to add a certain proportion of the corresponding "low-melting fiber"; manufactured by thermal bonding. Source: National Plastics Processing Industry Information Center
