Aluminum Foil Roll for Pharma Powder Packaging
The effect of pinholes on medical aluminum foil: Medical aluminum foil metal aluminum has a highly dense metal crystal structure. A perfect medicinal aluminum foil can completely block any gas, water vapor and light.
But in fact, because the rolling process used in the production of medicinal aluminum foil, the quality of the rolling oil, the condition of the rolling roll surface, the process operation technology, and the production site environment are all affected by many factors, the medicinal aluminum foil, especially Thin aluminum foil will inevitably have various defects, and pinholes are the main ones. The size and quantity of pinholes is one of the important indicators to measure the quality of medical aluminum foil products.
It is precisely because of the existence of pinholes that the permeability of oxygen and water vapor to the medicinal aluminum foil is not zero. The size and number of pinholes of medical aluminum foil have a decisive influence on the moisture resistance, gas barrier properties and light-shielding properties of aluminum foil and its composite materials. Our company has extremely high standards for this.
It has a gorgeous metallic luster, high-resistance, heat-sealing and air-tightness, and has a good barrier and moisture-proof effect on air, water vapor, light and other gases. Excellent mechanical properties, heat resistance, low temperature resistance, corrosion resistance, suitable for high-speed automatic packaging machines in various climatic environments. The product is mainly used for blister packaging of medicines, tablets, capsules, suppositories, pills, snacks, and candies.
Aluminum Foil Roll A Grade Quslity Double zero aluminum foil is relatively thin and is mainly used in the packaging industry, such as food packaging, cigarette packaging, etc.
