  • Detail

Current situation and development trend of drug packaging at present, China's drug packaging industry has more than 2000 large and small enterprises, which can produce more than 30 varieties of drug packaging materials in 6 categories, which can basically meet the needs of the domestic pharmaceutical industry. The annual sales volume has accounted for about 15% of the sales volume of the whole pharmaceutical industry. From the current application and development of pharmaceutical packaging containers in China, we should speed up the promotion and application of pharmaceutical oral liquid plastic containers to give full play to the respective advantages of enterprises and scientific research institutions. The specifications range from 100ml to 200ml. The applied raw materials are polyethylene terephthalate (PET) and new material pen, including the development of high-quality pet plastic bottles that are dark and have scales on the containers or are attached with measuring cups, To replace low quality glass bottles. As the pills, capsules and powders of traditional Chinese medicine in China have a large development space in the international market, it is necessary to speed up the development of plastic hollow container packaging of traditional Chinese medicine. For example, plastic hollow containers made of high-density polyethylene (HDPE), polypropylene (PP), pet, pen and other materials have long-term cooperation units, and adopt injection blow molding and injection drawing blow molding processes. The mouth of the hollow container is sealed with aluminum foil electromagnetic induction gasket to increase the safety protection of the packaging container for drugs, and eliminate the backward packaging of drugs with yellow round glass bottle sealing wax

according to the report of American flexible packaging Association: in the next five years, drug packaging will become the second largest economic growth point of flexible packaging. The report also points out that, in addition to the strong development momentum of medical supplies, the packaging of medical supplies is also developing rapidly. It has come out to replace the bulk or bottled drug packaging with the friction packaging between the thermoforming extrusion blister lowering tool and the workpiece that can control the dose. In the plastic composite film bag packaging of granules, powders, powders and capsules of traditional Chinese medicine, which are mainly popularized and applied in China, the following varieties are mainly developed:

I. biaxially oriented polypropylene (BOPP) film. This kind of film has good transparency, heat resistance and barrier property. It can be used in the outer layer of composite bags. When it is compounded with LDPE, e-va, EEA, EAA or aluminum foil with good heat sealing property, the stiffness and physical and mechanical properties of the composite film can be greatly improved. If the BOPP base film is coated with PVDC with excellent moisture-proof and barrier properties, its impermeability can be greatly improved

II. Cast polypropylene film (CPP). It has good heat sealing property and is mostly used for the inner layer of composite packaging bags. After vacuum aluminizing, it can be compounded with BOPP, pet, OPA and Pt

III. polyester film (PET). Biaxially stretched polyester film has extremely high mechanical strength and rigidity, extremely high heat resistance, excellent drug resistance, excellent transparency and gloss, small water and oxygen permeability, and particularly good taste retention, which is unmatched by all other films

IV. polyvinylidene chloride film (PVDC). It is a kind of film with the best barrier performance. It is divided into heat-resistant coating films, such as gas resistant PP, CPE, pet and coated PVDC film. The low-cost PVDC coating/PP composite film can be used not only in drug packaging, but also in heat-resistant coating and packaging of heated food. PVDC film is more widely used. It can be used to package natural dairy products. It has oxygen resistance and can prevent mold from producing carbon dioxide during its ripening process. At the same time, it can also be designed as a gas blocking PVDC film bag with a pressure reducing valve. It can be used under high temperature and high humidity conditions. It has excellent resistance to oxygen and moisture during transportation and storage. PVDC coated composite film for medicine and food is used to make high-temperature cooking sterilization bags and fresh-keeping and anti-corrosion bags in China. At present, the imported PVDC coating film has been widely used in the packaging of meat products, pastries, tea and solid drinks. The safety device: overload protection and plays the role of preventing water loss, blocking gas, maintaining flavor, corrosion prevention, preservation, etc
