Blister packaging for material control For blister packaging aluminum foil is the main material to cover the opening, is also a good barrier packaging material, pinhole in penetration is a fatal defect. During the packaging, transportation and storage process, extrusion, collision is inevitable, so the size of the pinhole or the range of aluminum material or increase, which may cause the material to have obvious fracture marks, which may lead to deterioration in the properties of aluminum material it speeds up the infiltration of gas and water vapor, affecting the stability of the aluminum material. In general, there are two methods to accurately assess changes in pinhole conditions and changes in covering materials. 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 refle

Material requirements for pharmaceutical blister packaging The packaging of drugs must meet the requirements of dampproof, mildew proof, ice proof, heat proof and light proof. Metal aluminum non-toxic tasteless, has excellent shading, resistant to moisture, cut off gas and the security properties of odour, theoretically perfect foil can completely prevent gas, light, packaging can be the most effective protection by drugs, asked to use opaque packaging materials, almost all of the materials, aluminum foil are used as the barrier layer, therefore, the aluminum foil in pharmaceutical packaging is widely used, is usually a direct contact with the drug use the main packaging materials. As far as the present situation is concerned, the quality of aluminum applied drugs in China still lags behind that of imported products, which is mainly reflected in the following aspects: the quantity of aluminum pinholes cannot meet the demand of drugs. The number of needles on the aluminum foil is

The development of Blister packaging PVC Pharmaceutical packaging PVC board made from PVC resin, add a few auxiliary technology through extrusion processing method in the production of qualified drugs, as an independent aluminum-plastic packaging substrate, each piece of tablets and capsules independence, become the smallest unit of medical packaging, make drugs safe, accurate, because the processing method is simple, small investment, easy processing, reduce pharma pharmaceutical production costs, improve production efficiency. Because vinylidene chloride polymer density, uniform structure, in high humidity environment will not leak, excellent water resistance, resistance to oil and solvent performance is poor, especially for oxygen in the air, water vapor and carbon dioxide has a high performance barrier. In addition, impact resistance, tensile strength, seal durability and other indicators can meet the special requirements of pharmaceutical packaging printing, the future devel

Blister packaging material printing ink Drug used for blow-cover packaging ink can be divided into two categories: one is the distribution of gliadin polyamide ink printing materials with good adhesion, gloss, wear resistance, good solvent, mainly used in plastic printing, its thermal stability can also meet the needs of aluminum printing, is the majority of medical aluminum foil printing materials. The problem with this type of ink is that ink stripping occurs when large area surface of aluminum foil is printed. Secondly, it is a kind of vinyl chloride, vinyl acetate copolymer resin and acrylic resin as the main components of special aluminum foil ink. This is a newly developed rotary gravure printing ink with bright color, high concentration, special adhesion to aluminum foil, good transparency, good reproducibility of aluminum foil metal luster, etc. But because it is a gravure printing ink, the solvent is volatile. PTP aluminum foil used in medical printing tends to produce d

Blister packaging material development Drug packaging is an important aspect of drug processing and quality assurance. Because of the increasing requirements on the safety, quality and shelf life of drugs, the pharmaceutical industry has increasingly higher requirements on packaging. Modern drug packaging should not only meet the needs of consumers to ensure the quality, freshness and safety of drugs, but also play an important role in preventing corruption, drug poisoning and raising awareness in the context of the emergence of new packaging concepts. At present, the demand for blister packaging materials in China's medical industry has the following trends: the exclusivity of anti-counterfeiting packaging; The anti-counterfeiting of various packaging materials is more conducive to promoting the production of customized packaging products; Anti-bubble packaging must be clear, clear, simple and feasible for the patient. The overall quality of medical aluminum foil in China is

Blister packaging aluminum foil holes Blister packaging is one of the most widely used and fastest developing flexible packaging materials in the pharmaceutical industry. It is the main packaging form of solid drug formula in China. It has excellent air tightness, excellent moisture resistance, good oil resistance, drug resistance, solvent resistance, excellent oxygen resistance, water vapor and carbon dioxide gas in the air, which can meet the special requirements of blister packaging medicine. Use aluminum foil as the printing medium, its surface must be clean, bright, high quality. Aluminum foil coating can be used strictly to ensure that the aluminum foil substrate is closely related to the composite coating of the blister cover. Aluminum foil is non-toxic and tasteless, with good electrical conductivity and opaque light, very resistant to humidity, endurance and gas odor protection material, can more effectively protect the packaging of drugs, packaging is a metal film can not

The main application of blister packaging Blister packing machine is suitable for mechanical packing of solid preparations. It has very obvious advantages, such as drug stability and reliability, easy to achieve small batch and batch packaging, advanced technology, safety and health, easy to transport and use, long storage time, good adaptability, beautiful appearance, but also with identification, anti-counterfeiting and other characteristics. Blister packaging currently accounts for approximately 30% of the world pharmaceutical packaging market and continues to grow strongly. In the future, ba-cap packaging will become the main form of packaging tablets, capsules, pills, bulk, powder, particles and other drugs. Packaging should be solid preparations as the main object, packaging should contain preparations and isolation from the outside world, while preventing the active ingredients volatilization, leakage and leakage. Volatile pharmaceutical ingredients are dissolved in the pa

Application of blister packaging materials The coating adhesion of coating layer thickness has a great impact on the process of printing, coating adhesion rigid PVC plastic adhesive layer is too thin, due to the lack of materials, the thermal pressure on THE PVC board will reduce the viscosity; Adhesive coating thickness is too large, not only increased the cost, but also increased the drying time, so should be kept in the appropriate thickness. Adhesive coating thickness is affected by adhesive concentration, coating tension, coating speed and anilox roller line number. With the adjustment of shape, depth, the number of lines per inch and the pressure of the two-roller contact line, the higher the adhesive concentration, the lower the film tension, the faster the film speed and the greater the film thickness. Therefore, the thickness of adhesive layer is usually adjusted by the concentration of adhesive and the tension of coater. For different varieties of aluminum foil, adhesive t

Ink printing of blister packaging materials When high viscosity ink needs to be diluted with a large amount of diluent, add diluent agitation, so that the diluent evenly distributed in the entire ink. Measure between 20 and 30 with a viscometer. Room temperature and humidity will affect the concentration of ink, it is recommended to use ink concentration detector to determine the amount of added solvent, and according to the temperature and humidity changes, regularly determine the concentration of ink. When using intaglio printing to print aluminum foil products, the ink concentration is too low, which will lead to the color of the printed text pattern is not bright, and there will be paste phenomenon in the printing. Ink concentration is very high, so the pattern will produce cracking phenomenon, not only waste ink, and easy to cause the printing surface irregular, not beautiful. In addition, according to the speed of aluminum foil coater and gravure roller ink hole depth, choose
