Tegenwoordig, De aluminiumfolies worden in veel industrieën veel gebruikt. Zoals flexibele verpakkingen, keuken gebruik, thermische isolatie en ander gebruik. Tijdens deze industrieën, soms is kale folie niet voldoende om te gebruiken, we moeten de folie lamineren met ander materiaal zoals papier, PE, PVC enz. However do you know how the foil was produced? And there some aluminum foil use may more than you imagine.
Aluminum foil provides a complete barrier to light, oxygen, vocht en bacteriën. Om deze reden, foil is used extensively in food and pharmaceutical packaging. Aluminum foil is also used to make aseptic packaging. This type of packaging enables storage of perishable goods without refrigeration
The origin of aluminum foil can be traced by to the early 1900s. Life Savers—one of today’s most popular candies—were first packaged in foil in 1913. To this day, the treats are encased in the world-famous aluminum foil tube. The uses of foil have grown over the past 100 years to a nearly endless count. From Christmas tree ornaments to spacecraft insulation, TV dinners to medicine packets—aluminum foil has, in many ways, improved both our products and our lives.
How aluminum foil is made
Aluminum foil is produced by rolling aluminum slabs cast from molten aluminum in a rolling mill to the desired thickness. To maintain a constant thickness, a technician monitors the rolling mill sensors to ensure the pressure on the slab is correct. Sensors are able to tell the technician if the pressure is too great or not enough and then the technician can adjust the rollers to apply more or less pressure. It is then coiled and sent to the cold rolling mill. To avoid breakage because of the thinness, the foil is doubled in the cold rolling mill and the rolled to the desired thickness. Aluminiumfolie provides a complete barrier to light, oxygen, vocht en bacteriën. Om deze reden, foil is used extensively in food and pharmaceutical packaging. It is also used to make aseptic packaging that enables storage of perishable goods without refrigeration.
