You’ve probably been in this scenario, you and some friends or family members chilling on a Sunday afternoon in front the TV watching that movie you were meant to watch for a while ago, whereas sharing a bag or two of your favorite potato chips.
The question that remains is what do you do with the new-emptied potato chips bags? Do you throw them into the garbage can? Or do you put them into a recycling bin?
The correct answer may depend on what kind of material your potato chips bags are made of. Most potato chips bags are made of Mylar, a fusion of plastic film with a sort of metallic ink. Mylar is not recyclable. It is important to note that just because it is shining it does not mean it is aluminum foil. To make the difference, crumple up the wrapper or packaging. If it springs back to its original shape, then it contains some plastic and cannot be recycled.
You may wonder why metallic chip bags are used to store potato chips rather than plastic packaging. It happens because the metal content of the film provides a superior barrier to oxygen over pure plastic; which allows the product to maintain quality longer. In their unsaturated oil content rancidity is an issue. It’s known as Modified Atmosphere Packaging, and it shows up in other places as well. In oxygen-sensitive foods (potato chips are a great example, as the oil content makes them susceptible to rancidity) the in-package atmosphere usually decreases the oxygen and increases the nitrogen content.
Shanghai Metal Corporation offers Laminated Aluminum Foil consists basically using adhesive, pressure to combine 6-9 micron aluminum foil with one or more other materials, such as paper and plastic films etc. Laminated aluminium foil film have great seal abilities, and good chemical and water resistance. Its advantages are excellent as they are opaque, with good oxygen barrier, well formed, and maintain fresh the content with long-term preservation.
