Ordinary plastic bags and aluminium zipper pouches are our commonly used packaging products, whose uses, costs, and environmental performance are different. Heat seal aluminum foil bag for food is made of aluminum and other high barrier materials by dry lamination according to the unique properties of aluminum. It is extremely thin that formed by calendering high purity aluminum for many times, which is an excellent heat conductor and light shield. The purity of aluminum foil for packaging is more than 99.5%. Vacuum aluminum coating is a kind of thin film which accumulates the vapor of aluminum on various substrates in high vacuum, while the thickness of aluminum coating is 350-400A. What are the respective advantages of aluminium retort pouches? Today we will make a comparison for you, so that you can have more emphasis in your future choice.




Different Applications


Plastic bags are more convenient to use and have a wider range, which are used in almost all walks of life. However, the white plastic pollution is very serious in China and the white plastic used in food and daily necessities packaging often has a certain toxic effect, so the role of aluminum pouches for food has been highlighted. It is easy to find that its advantage is the effective protection for food, which is also very reliable in terms of quality.



Cost Difference


The higher cost of heat sealing aluminum foil leads to the wide application of plastic packaging. However, after measuring the cost performance of the two, aluminum foil products often appear in the packaging of food, medicine, and other types of products. Because aluminum foil pouches are safe and reliable, which can realize vacuum compression, so its wide application comes from various advantages.



Comparison of Environmental Performance


Products with environmental protection effect can often bring very reliable support and protection, so we can't absolutely say that plastic itself is more toxic. The production cost of completely safe and non-toxic plastics is relatively high, so you must consider this aspect in the selection of plastic products. In terms of environmental protection and cost performance, aluminum foil insulation bags seem to bring more protection, so you can choose according to the needs of users.
