The feeder of bubble cover packing machine Filling the molded plastic grooves can be filled with a variety of forms of feeder, and can be filled into a row of grooves at the same time. Through strict mechanical control, the gap of the single grain feeding in the plastic groove, but also a certain speed of uniform spread type feeding, at the same time to a number of rows of grooves in the feed. Only a single drug can fall into the grooves or holes of the rotating baffle limited by scraping plate or fixed baffle between the hopper and the rotating plate. The rotating speed of the rotating partition should match the movement speed of the foam plastic film, that is, to ensure that each row of grooves on the film falls into a single drug. If there are several rows of concave bubbles on the plastic film, sufficient length or number of rotating partitions should be set accordingly. For the horizontal axial partition on the left side, sometimes no soft leather board, but for the width of the

The advantages of aluminum materials Compared with other packaging materials, aluminum material has the following advantages 1, aluminum is non-toxic and tasteless, in line with the health standards of packaged food. 2, aluminum surface gloss is high, easy to color, good printing effect. 3, The opening performance of the easy open cover made of aluminum is better than that of the tin plate. 4, the mechanical properties of aluminum can remain unchanged at low temperature, especially suitable for frozen food packaging. 5, waste can be recycled, can save energy consumption and prevent waste caused by public hazards, to meet the requirements of environmental protection. 6,Aluminum has excellent reflection and conduction properties of light and heat, which can improve the effect of heating sterilization and low temperature processing of food cans. 7, the composite film made of aluminum foil is completely impermeable and impermeable to light, which can effectively protect the food in

Bubble cover machine forming method Molding is an important process of the whole packaging process, bubble cover molding methods can be divided into the following four. (1) blister forming (negative pressure forming). Vacuuming was used to suction the heated and softened film into the alveolar fossa of the forming pancreas into a certain geometric shape, so as to complete the formation of the alveolar fossa. Blister molding generally adopts roller mold, forming bubble cover size is small, simple shape, bubble cover stretching is not uniform, the top is thin. Blow molding (positive pressure molding). Compressed air is used to blow the heated and softened film into the bubble cover socket of the molding mold to form the bubble cover with the required geometric shape. The forming bubble cover wall thickness is relatively uniform, the shape is quite broad, can be formed with large size bubble cover. Blow molding is mostly used for plate molds. Punch auxiliary blow molding. With

The development of packaging materials The development of packaging industry is an important symbol of cultural development and scientific and technological progress. Since the 1950s, the rise of composite materials has triggered a revolution in the field of packaging, and the continuous development of composite technology. At present, a variety of new composite materials have emerged, which has a certain impact on the application of aluminum foil. Such as: 1) due to the aluminum foil packing food cannot be directly for microwave processing, a high separation are the latest in a microwave food packaging materials, namely on the base material such as plastic plating a thin layer of silicon oxide, make the material has high barrier property, high microwave permeability and transparency, suitable for high-temperature cooking, microwave processing, such as food packaging, packaging, can also be used for beverage and cooking oil However, the production cost of this material is very hi

PVC hard sheet for cold stamping Cold stamping molding hard sheet surface support strength layer, aluminum foil barrier layer, inner surface heat sealing layer between the three layers of adhesive bonding method, they organically combined. To become a composite material as a whole, to ensure that the cold stamping hard plate house strong impact forming force is not business layer, not fracture, the selection and use of adhesives is quite key, general requirements after bonding aluminum box and surface type strength holding layer and heat sealing layer bonding strength is more than 8N/15mm, In the process of formulation design, the ratio of soft and hard segments of molecular pin segments in nitrogen-coated adhesive should be controlled. In order to meet the requirements of cold stamping molding, the general adhesive is difficult to meet the above requirements, so the adhesive used for cold stamping hard piece is generally a special adhesive specially prepared. Cold injection pressure

Forms and characteristics of drug packaging The packaging form of common medicines Film direct packaging packaging bag the most commonly used packing form of granules. Generally choose high density polyethylene, polypropylene, polyvinyl chloride. The outer layer of the compound drug bag is high melting point thermoplastic material or non-plastic material such as paper, aluminum foil, nylon, polyester and stretched polypropylene. The inner layer is unstretched polypropylene, polyethylene and other low melting point thermoplastic materials. Blister packaging is a new type of compound packaging for tablets, capsules and parts, commonly known as "blister" or aluminum-plastic packaging. Hollow packaging adopts injection blow molding or extrusion blow molding method in a certain shape of the mold made of bottles, tubes, cans, barrels, boxes and other packaging forms, mainly used for tablets, capsules, ointments, liquid pharmaceutical packaging. Press-molded packaging Strip packaging Spec

The operation process of blister packaging machine The PVC sheet on the drum passes through the guide roller, and the PVC sheet is evenly unrolled by the rotation of the roller forming mold. The semi-arc heater heats the forming mold to the softening degree. The bubble hole of the forming mold rotates to the appropriate position and the vacuum system of the machine is understood, and the SOFTENED PVC sheet is formed instantly. The molded PVC sheet passes through the hopper or the feeding machine, and the tablet is filled into the bubble shell. Active roller in the continuous rotation of a thermal device only similar to the molding groove on the surface, drag the active roller as have some pills to PVC foam nest to move forward, the surface with a checkered hot pressing on the active roller, roller pressure using the temperature and pressure will cover material (aluminum foil) and PVC sealing, sealing PVC blister sheet after the use of a series of guide roller, Intermittent movement

Transparent blister pack Packaging design needs to follow one of the principles is to fully display the goods, mainly in two ways, one is to use vivid color photos on the package to truly reproduce the goods; The second is to directly display the commodity itself, that is, to use transparent packaging, skylight packaging and other forms of packaging. Transparent packaging is very attractive because of its transparent characteristics, which provides consumers with the advantage of clearly seeing the content, completely in line with people's shopping habit of "seeing is believing", so it is favored by consumers. The scope of transparent packaging is very wide. In addition to bottles and bags, it is generally considered that the single-sided transparent packaging of cardboard base blister packaging, partial transparent packaging of window packaging, single-sided transparent packaging of body packaging and double-sided transparent packaging of clamshell blister packaging all belong to th

The use of blister packaging Blister packaging The original blister packaging is 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, coupled with the increasing demand for dose packaging, small pill packaging, bubble packaging appeared in the 1950s and has been widely used. Later, through the in-depth study and continuous improvement of blister packaging materials, technology and machinery, it has made great progress in packaging quality, speed and economy. Now in addition to drug tablets, capsules and suppositories and other packaging, food and daily necessities and other products are also widely used in packaging. 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
