Household Aluminum Foil and PTP Blister Foil

1. Household Aluminum Foil and PTP Blister Foil Abstract: Aluminum foil is widely used in our daily life and professional fields such as medicine packaging due to its good barrier properties. What are its magic uses? Lets have a look. Magic Uses of Household Aluminum Foil Which side of aluminium foil to use The household aluminum foil usually has two sides: shiny and dull surface. The dull surface is actually rough and easier to absorb heat and the shiny surface is smoother. In terms of scientific point, the shiny food should be used to wrap the food and the dull side should be up. However, there is little difference in the practical effect of daily cooking. Magic uses of household aluminium foil Since household aluminium foil is widely used in our daily life, what are its magic uses? Lets’ have a look together. Barbecue When baking food in a small household oven, because the distance between the electric heating tube and the food is very close, it is easy to burn the surface, but the inside of the food is not cooked enough. One piece of household foil can solve this problem easily.  Fold the aluminum foil paper according to the size of the baking pan.  Form the shape of a cave cross the whole baking pan. At this time, put it into the oven. Because the space inside the

2. aluminum foil is heated to form a thermal cycle, and the food can be evenly heated. Peeling fruits and vegetables The fruits and vegetables with irregular shapes and thin skin are not easy to peel, such as potatoes, burdock, ginger and lotus root. It is more convenient to scrape off the skin with a small ball of aluminum foil than a planer. Cold storage Roots and stems such as onions or carrots that have been cut but not used up are usually wrapped in plastic wrap when they are put in the refrigerator to prevent the moisture in the ingredients from losing too quickly and to avoid the refrigerator from being contaminated with peculiar smells. It is better to use aluminum foil paper for wrapping.

3. Fridge cleaning There will inevitably be some soups in the fridge, but the shelves often become dirty as a result, and it is very troublesome to clean up. It is recommended to select a layer dedicated to this kind of food, and spread household aluminum foil on this layer, which can be used for anti-fouling and can be easily replaced. Grilled net cleaning The grilling net inside will definitely be covered with greasy dirt after a long time of use. Wiping it with aluminum foil paper can remove most of the dirt. What Are Defects of Aluminium Blister Foil The pharmaceutical blister packaging consists of PTP aluminum foil, medicinal polyvinyl chloride (PVC), printing materials, protective agents, and adhesives. Its production process is to put the medicine in the pit of a plastic hard sheet formed by blister, and then press and seal the plastic hard sheet with a piece of aluminum blister foil that has been printed and coated with a protective agent and adhesive. During the rolling process , the quality of the rolling oil, the condition of the rolling roll surface, the process operation technology and the production environment and other factors all will affect the aluminum foil quality.

4. Aluminum foil, especially thin aluminum foil, inevitably has various defects, and pinholes are the most important one. The size and number of pinholes in aluminum foil have a decisive influence on its final performance such as moisture resistance, gas barrier properties and light-shielding properties. If the breaking strength of pharma foil is poor, it will often break in the printing and coating. If it is broken in the drying tunnel of the printing machine, it will take a long period to deal with the problem due to the high temperature of the drying tunnel. The standard thickness of pharma foil is 0.02±0.002 mm. Thickness measurement should be measured by microcalor or LG-l optical thickness meter with an accuracy of 0.5-1.Oum. The width of the aluminum foil should be measured with a steel ruler with an graduation of 0.5 mm, and the length should be measured with a counter. If the surface of the pharma foil has serious quality defects such as oil stains or indentations, it will not only affect the clarity and integrity of the printing and text, but also it will fade when it is painted in gold. It also will affect the coating quality of the protective agent and adhesion, thus

How to Control Pinholes of Pharmaceutical Foil Pharmaceutical blister packaging is widely used in the pharmaceutical industry due to its beautiful appearance, good barrier properties and portability. It is currently the most important packaging for solid dosage forms such as pharmaceutical tablets and capsules. Pharmaceutical foil(usually called PTP aluminum foil) is one of the two major constituent materials of this packaging method, and its pinhole degree will directly affect the protection of the final packaging to the contents. Because if the PTP aluminum foil pinhole is just in the blister, it means that the medicine is in direct contact with the outside air, and the protective function of the medicine packaging will be completely lost, which will bring great risks to the manufacturers and users of the medicine.

6. There are two reasons for the pinholes of blister foil: 1. The pinholes in the production process of aluminum foil jumbo roll; 2. The pinholes in the production process of PTP aluminum foil. Since the pinholes in the PTP aluminum foil production process are relatively easy to control and avoid, we should mainly focus on the pinholes generated in the production process of the raw material aluminum foil for PTP aluminum foil. The pinhole control of pharmaceutical aluminium foil is a systematic project, which involves the three links of aluminum foil blank production, raw aluminum foil rolling, and PTP aluminum foil production. Effective quality control must be carried out on these three links to minimize the production of pinholes. Haomei Aluminum keeps strict control of the whole aluminum foil manufacturing process. We will have a preliminary judge when we find he pinholes in the sample protection even if it is within the allowable range. Once it is judged to be caused by the aluminum blank problem, the relevant batch of aluminum foil will be sampled more to better evaluate the overall pinhole condition. We also pay attention to the cleanness of the production equipment and ensure that no hard debris particles adhere to the equipment rollers.
