Blister packaging material characteristics PTP plastic board is the most commonly used PVC board. Although PVC has a lot of advantages, such as good quality, low price, but in the moisture-proof, mildew-proof, water-proof, anti-oxidation and other aspects are not very good. In addition, the production or use of PVC has a long-term impact on both the environment and biology. In the preparation of PVC plastics, the main problem is the polymerization of vinyl chloride monomer, such as vinyl chloride monomer additive, plasticizer, stabilizer and so on. PVC incineration process products such as dioxins hydrochloride. Hydrochloric acid produced after PVC decomposition has a certain impact on the environment, and its monomer, plasticizer and stabilizer are harmful to human body. At present, foreign developed countries began to ban and restrict the use of PVC bubble packaging, the need for new packaging plastic bubble must be synonym, oxygen and water, good performance to ensure the effective

Development of blister packaging In addition to all kinds of bottle packaging, blister packaging can be considered as the most commonly used packaging. Blister packaging has many advantages, it can provide patients with a single dose of drug packaging, convenient and economical. In addition, aluminum-plastic blister packaging protects the performance of the drug, which is fast in production, low in cost, small in storage space, light in weight, convenient in transportation, safe and reliable. Because blister packaging has instructions printed on the surface, incorrect distribution of several tablets can be avoided. Therefore, blister packaging will become the main way of tablet and capsule packaging. The following is a brief introduction to the characteristics of pharmaceutical blister packaging and the problems that should be paid attention to in the printing coating. Blister packaging is the most commonly used ideal packaging method in drug packaging. By aluminum foil, formi

Control of blister packaging materials Aluminum foil is the main material to cover the opening, is also a good barrier packaging material, pinhole is a fatal flaw in penetration. May occur during the process of packing, transporting and storing filler extrusion, extrusion is inevitable, so the increase of the diameter of the aluminum foil pinhole or range, which may lead to obvious crease, this can lead to a breakthrough in the aluminum material properties, it accelerated the gases and water vapor permeability, influence on the performance of the stability of aluminium material cut off. In general, there are two methods for accurately assessing changes in pinhole conditions and covering material barriers. First of all, it is suitable for the kneading behavior that may occur during the circulation of packaging materials through the kneading test device. Secondly, the strength of coating material before and after friction is tested, and the change of data directly reflects the chan

Blister packaging for the application of milk tablets Milk slice is a product made of milk powder, vegetable cream, whey powder and sucrose after extrusion. At present, the vast majority of milk tablets are packaged as flat blister packs, which play an important role in storage and transportation. The packaging of blister plastic, also known as aluminum-plastic packaging (pressure packaging), is made by blanking and cutting the contents of the blister under certain pressure, temperature and time to form a vacuum (breathing) blister plastic or aluminum blister plastic shape, seal and substrate. Most of the covering materials are aluminum foil roll electrolytic aluminum. It is the most widely used metal material in packaging, non-toxic and tasteless, with excellent moistureproof, moistureproof, preservation, light resistance, so that the contents get more effective protection. After single-sided printing, the aluminum foil is coated with a protective layer, and the unprinted alumin

Blister packaging for other test items Blister packaging to ensure the sealing and independence of each bubble shell, it should ensure the good heat sealing, otherwise, when the drug from one of the bubble shell taken out, the remaining bubble shell is easy to leak and break, leading to water loss, drug deterioration and even diffusion. Therefore, the detection of thermal fitness is an important index of blister packaging quality. Test method: Select appropriate parameters for heat sealing according to the specific reference standard, and use this tool to heat seal the composite PVC and PVDC composite hard sheet and aluminum foil, and cut the specimen to a width of 15mm. Take the middle three pieces and peel them off with a tension machine at 180° (specific implementation of the treatment standard for detection). What needs to be done for the peel is the thermal strength. The base of blister packaging is usually made of medical aluminum foil. Medical aluminum foil vacuum is

Blister packaging testing PTP aluminum foil and hard PVC foil or PVC/PVDC composite materials used for blister packaging are in direct contact with drugs, requiring special attention to material analysis, and there are many national standards. Tensile strength: Test objective: During the use of solid medicinal low density polyethylene film bag, in addition to some external forces, the necessary mechanical properties are determined through the test to ensure that its mechanical properties meet the standards. Test method: Tensile strength method refers to the tensile property index determined according to the test verification results. Generally, the longitudinal and transverse average tensile strength is not less than 10Mpa. The elongation at break method refers to the determination of the tensile properties of thin films with a thickness of less than 0.05mm and an average elongation of no less than 130% according to the test verification results. For thin films greater than

Blister packaging and blister packaging Although blister packaging and blister packaging belong to the same type of packaging, they have their own advantages and disadvantages due to slightly different packaging methods. Users can choose according to the actual situation: Common features of blister packaging and blister packaging: Generally speaking, the packing is transparent and almost all the goods can be seen. Through the substrate design, the packaging can be hung on display in shopping malls and retail stores. The shape of the substrate and fine printing can enhance the advertising effect of the product. Goods with complex shapes can also be packed. Can be packaged in groups. Generally speaking, the cost of packing is higher than that of other packing methods. Different features of blister packaging and blister packaging: 1. Packaging operation: Fit packaging is suitable for a variety of varieties and a small amount of production, no mold is needed. Blister packaging is

Blister packaging status quo Aluminum foil has been around since the early 20th century. Since the 1990s, aluminum foil production has entered a critical stage, not only the introduction of modern equipment, but also the production management and technical research level is increasingly modernized and international. In the first half of the 20th century, market competition and product homogenization accelerated the rapid development of packaging. The development of aluminum foil packaging and the development of the whole industry. At first, aluminum foil packaging was mainly used to package medicine. All PVC paper and 0.02 mm thick tin foil are used for blister packaging. In western medicine, blister packaging has become the main means of packaging. Traditional plastics, oxides, capsules and spheres use a paper bag and are converted between a plastic bag that USES a simple plastic bottle and a glass bottle. The report says photonics is the country's most important external means of
