Presa Procezo De Medicina PTP Aluminia Pakado

One of the functions of aluminia folio is to be used as a packaging material for medicines. Because of the excellent material properties of aluminum foil, this kind of packaging can retain medicinal properties and shelf life excellently. Not only that, but people will also print on the surface of the packaging aluminum foil, attaching information about medicines and pharmaceutical factories. And what about the printing process of medicinal aluminum foil?

Different manufacturers may have some different implementation standards for the printing of medicinal foil, but the general process is similar, mainly the following processes: aluminum foil unwinding→gravure printing→drying→protective coating→drying→coating and bonding Layer→drying→aluminum foil winding. In the entire production process, the higher requirements for production technology are the surface quality of the gravure printing text pattern and the heat seal strength to be achieved by the adhesive layer, the adhesion of the protective layer, and the speed and tension control of the coating machinery. It is necessary to strictly control the process operation. These are crucial to the final effect of packaging printing. Tial, in the “Aluminum Foil for Pharmaceutical Packaging” normo, there are clear requirements for the surface quality of the printed text of the medical aluminum foil, and the performance of the protective layer and the adhesive layer also have physical and chemical indicators, so as to protect the medical PTP aluminum foil with better barrier properties, Hygienic safety, heat sealability, and good physical and mechanical properties.

If you want to get better aluminum foil prints, it is not enough to complete these processes alone. Because of the special properties of raw materials, these points should also be paid attention to in the production process.

1. Control The Characteristics Of Aluminum Foil And Printing Ink

The raw material used in the production of PTP aluminum foil is industrial pure aluminum foil. Generally, the thickness is 0.02mm, the tensile strength is 98kPa, the bursting strength is 90kPa, the surface is clean, flat, without wrinkles, indentation damage, and no fluorescent material. The surface wetting tension is not less than 32. The requirement for the pinhole degree of medicinal aluminum foil is that the pinholes with a diameter of 0.1—0.3mm should not be more than 1/m2. Inter ili, every detail needs to be controlled to prevent oxygen, water vapor, and light from entering due to leaks in the production process, which will reduce or deteriorate the efficacy of the medicine. Inter ili, the requirements for pinhole degrees are very strict. . Krome, if the thickness of the raw material aluminum foil exceeds the required deviation (10%), it will also have a greater impact on the adhesion layer and the protective layer.

2. Add The Solvent To The Ink Properly

When the ink with high viscosity needs to be diluted with a large amount of diluent, in order to prevent the problem of adhesion and solidification, the diluent should be added while stirring to make the diluent evenly distributed in the entire ink, and according to the changes in temperature and humidity, at regular intervals Measure the ink concentration at the appropriate time and make adjustments in time. When printing aluminum foil products by gravure printing, the ink concentration is too low, which will cause the color of the printed text and patterns to be not bright, and the texture of the screen will produce a paste; if the ink concentration is too high, the image will be cracked, which not only wastes ink but also easily Cause the printing surface to be uneven.

The quality of medicines is related to the safety of human life. When all products are produced, quality should be put in the first place to provide people with the most healthy and high-quality services. For more than ten years, Huawei Aluminio has been adhering to this business philosophy, and more and more are welcomed and trusted by all parts of the world. We will always maintain this original intention.
