High quality pharma foil supply from China

The high quality pharma foil 8011 8021 O H18 supplied by Haomei has thickness of 0.02-0.075 mm, its pinhole size is smaller than 1.0 mm. Improve the quality of aluminum foil and reduce the number and size of aluminum foil pinholes are the requirement of pharmaceutical aluminum foil manufacturers. Haomei has over 15 year experience on pharmaceutical packaging aluminum foil producing, so we have strict requirements on the pinhole number and size, we have test the pinhole of the finished medicinal aluminum foil.

Since the pinhole in the pharma aluminum foil is a softening defect, the drug is ineffective by the intrusion of oxygen, water vapor and light, so the request for pinhole is very strict. The surface of the pharmaceutical aluminum foil allows pinholes visible to the naked eye, however, the pinholes shall not be densely integrated, and the diameter of the pinhole of the medicinal aluminum foil shall not exceed 0.2 mm and shall not exceed 5/m2. The pinhole size of other industrial aluminum foils shall not exceed 0.5 mm. Because pinholes are an important indicator for the detection of aluminum foil, many technical materials have specified the amount of water vapor permeation and pinholes of aluminum foil.

As a professional pharmaceutical foil manufacturer in China, during the processing line, control the speed of the mill during the rolling of the finished aluminum foil to control the amount of oil on the surface and the brightness of the surface. During the slitting process, the tension and slitting speed are controlled to ensure that the edge of the pharma foil is neatly divided during the slitting process, and quality problems such as staggered layers, edge burrs, and ruffle edges cannot occur. If annealing is required, the annealing time and annealing temperature should be controlled on the annealing process to ensure the mechanical properties and surface degreasing.
