Advantages and disadvantages of blister packaging Blister packaging is one of the most widely used and fastest developing flexible packaging materials in pharmaceutical industry, and also the main packaging form of solid drug dosage form in China. It has strong gas sealing, excellent moisture resistance, good oil resistance, drug resistance and solvent resistance, excellent resistance to oxygen, water vapor, carbon dioxide gas in the air, can meet the special requirements of drug bubble packaging. The use of aluminum foil as the substrate, the surface should be clean and shiny, good printing suitability, can be firmly coated with heat sealing coating, to ensure that the melt of the heat sealing coating, the substrate and bubble cover can be closely combined. Aluminum foil is non-toxic, tasteless, has excellent electrical conductivity and shading, has high moisture resistance, gas resistance and taste protection, can most effectively protect the packaged drugs, is a kind of packaging

Types and functions of packaging There are many kinds and varieties of articles, and the circulation conditions are also very different. Therefore, there are many kinds of packaging techniques, which are commonly used as follows (1) Moisture-proof packing Moisture-proof packaging is to use materials with a certain ability to isolate water vapor to seal the goods, isolate the impact of external humidity on the product, or add desiccant in the packaging container, in order to absorb the residual moisture in the package and the moisture permeated by the outside. (2) waterproof packaging Waterproof packaging is a kind of protective measures taken to prevent the deterioration and damage of contents caused by water intrusion into the packaging container. (3) rust proof packaging Anti-rust packaging is to prevent the corrosion of metal items in the packaging and take certain protective measures of packaging. (4) Mildew proof packaging Mildew proof packaging is a kind of protective me

Blister packaging machine feeding filling Elastic yellow hose is stainless steel filament winding dense hose, commonly used ten to make the capsule aluminum bubble cover packaging, the inner diameter of the tube is slightly larger than the outer diameter of the capsule, can ensure that the tube only storage single row of capsules. Attention should be paid to ensure that the hose does not bend, so as to ensure the smooth flow of the cavity in the tube. Usually, with the help of the vibration of the whole machine, the hose shakes itself, so that the cavity can be stored in the lower exit. There are many forms of spring mechanism, can use ratchet, intermittent toggle spring opening and closing, and ensure that each lift once, only release a capsule, can also use the gap reciprocating motion opening and closing spring, release a capsule at a time. In the mechanism setting, there is usually a row of hoses with an intermittent mechanism to ensure linkage. Inspection using artificial or pho

The role of bubble cover packaging machine Blister packaging The original blister packaging was mainly used for drug packaging. At that time, in order to overcome the disadvantages of inconvenient use of glass bottles, plastic bottles and other bottled drugs, large investment in packaging production line, and the need for dose packaging, small pill packaging is increasing, so in the 1950s, bubble packaging appeared and has been widely used. Later, through in-depth research and continuous improvement of blister packaging materials, technology and machinery, great progress has been made in packaging quality, speed and economy. Nowadays, in addition to drug tablets, colloidal and suppository packaging, it is also widely used in the packaging of food and daily necessities. If the use of automatic packaging machine, but also improve production efficiency, reduce costs. A blister package for a drug, which can protect the product from moisture, dust, pollution, theft and damage, prolong the

Requirements for blister packaging materials Blister packaging is to directly contact with the drug, some of the drug storage for a long time, the quality of medical packaging is directly related to the quality of the drug, related to human health and safety. Therefore, the requirements for pharmaceutical packaging are as follows (1) Packaging materials should be non-corrosive, and have insect, moth, microbial inhibition and other properties to protect product safety. (2) Packaging materials should have good barrier performance. Packaging materials should be able to prevent moisture, steam, gas, light, aroma, odor, heat, etc. (3) Packaging materials should be suitable for processing, facilitate the mechanization and automation of packaging operations, in order to adapt to large-scale industrial production should be suitable for printing, convenient printing packaging logo. (4) Packaging materials should have certain strength, toughness and elasticity, which can effectively protect

Thermite blister packaging advantages Compared with the traditional blister packaging of "aluminum-plastic plate + aluminum-plastic sealing bag", the packaging of "aluminum-plastic plate + tropical blister aluminum" has more outstanding advantages. 1. Barrier performance The water vapor transmittance, oxygen transmittance and pinhole (that is, the small hole on the surface of bubble cover that can transmit light) were tested for traditional and tropical aluminum bubble cover packaging. Tests show that tropical aluminum blister packaging can completely isolate water vapor, oxygen and light until the contents are removed, while traditional blister packaging is difficult to achieve. 2. The reliability Due to the pinhole problem of aluminum foil itself, the aluminum foil at the hot sealing position is easy to be broken, which is the inherent characteristic of aluminum foil composite film. If the traditional blister package of aluminum plastic sealing bag on the flashlight, and then in

Blister drug packaging safety One of the major concerns of drug packaging is how to reduce accidents caused by children's exposure to or misuse of drugs. Statistics show that 30% of child deaths in many countries are due to accidental drug use. Some governments have even legislated to regulate all blister packaging of drugs because the packaging of such drugs is similar to that of many confectionery products. It is understood that China's drug packaging materials are still inconvenient to access, ingredients are not stable and lack of children's packaging and other problems. Recently, the State Food and Drug Administration revised the management method of drug packaging materials and improved the safety standard of drug packaging materials. The new standards are formulated uniformly by the state. It will replace the past national, industry and enterprise three-level standards, in the product material, modeling and stability, and other aspects, put forward higher requirements. The dru

Blister packaging machine character printing Word using the utility model for steel box and steel words in print have been heated to a certain temperature, the recycling cylinder movement driven shock ribbon steel word, steel words printed characters to be printed on, so increased the ribbon printing ink to be printed the caking ability of things, at the same time with color ink can be used more bright-coloured color, color to distinguish be printed material, Even if the background color of the printed object is light or reflective. Furthermore, the placement of an overrunning clutch helps the ribbon not to be reprinted. Overrunning clutch itself nature is its inner shaft between the outer axis is unidirectional rotation, reply when the cylinder movement (impact with ribbon in the opposite direction), driving steel type box back movement, set on the thimble contradicting the shifter lever, outside the shifter lever and the clutch shaft is fixed edge, so it drive shaft rotation, w

Blister packaging machine work characteristics Plate type blister packaging machine operation process and way of working: molding plastic is heated to softening at plate type preheating to remove plastic state, by step remove traction to the plate type forming remove, reduce air will soften hard blow molding of plastic (or stamping molding) into a blister, disassembly will be filling packaging filling into the blister, then transfer to a plate type sealing disassembly, Under the appropriate temperature and pressure, the plastic sheet of the cage cover is sealed with aluminum foil, and finally sent to typing, stamping and punching for disassembly. The batch number is punched out, the broken line is pressed out, and the plate is punched into the specified size. Namely; Molded plastic sheet unwinding → pre-holding → blow molding → material filling → sealing aluminum foil with cage cover → marking batch number → pressure breaking line → stepping → punching cutting → waste collection. In r

Packing machine connection table problem Blister packaging machine plate is docking PVC station, at the same time, there are two cylinder control PVC release and stop protection, when forming step traction, clamping cylinder release, when forming traction to reach the end of the traction, clamping cylinder clamping PVC, prevent PVC continue to move forward; The other cylinder of the plate platform is opened when the equipment is turned on and closed when it is shut down to prevent THE PVC from being burned by long-term sticking on the heating plate; The third function is to adjust the position of PVC, when PVC on both sides of the waste edge asymmetry can be adjusted to control the center position of PVC table block. Prone to two problems for splicing machine station, a problem, after each sheet PVC in forming step to run or fine, appear this kind of problem because of docking PVC edge is not neat, or butt paste transparent tape is not smooth, or is a splicing of retaining clip too t
