For every product, no matter what type or kind it is, packaging is an integral part although it's wise to use a minimal amount of packaging to cut down on costs and waste. When it comes to this particular need, the materials available for use include cardboard, plastic, paper and even some of the metal-type materials. Follow on for the basics on packaging and its common types.
While you hear people say that they purchase soup or chili in a tin can, canned goods are not actually packaged in cans produced using tin. For many decades, tinplate steel was used to produce the cans that hold our vegetables, soups, sauces and other canned items. Aluminum has been the most common source used to make canned goods since the late 1950s.
Aluminum has many advantages over tinplate steel as it is cheaper and easier to make yet it still resists corrosion. It is the most abundant type of metal found on the planet. Aluminum can be recycled again and again, in fact about two-thirds of all the aluminum that has been produced is still be used and reused today. Sadly, only about 50% of our aluminum makes it to a recycling center.
Different types of plastic are one of the most common materials used for packaging. Even items packaged in cardboard boxes and containers typically are just holding vessels for the sealed waxy plastic bags inside, such as the bags which hold cereal or crackers. There are actually seven basic types of plastic and each is identified with a special resin code, which is a number surrounded by a triangle of arrows.
As several different types of plastic materials are used in packaging, you should be introduced to the one responsible for holding liquid products like water and soda - which is polyethylene terephthalate. When it comes to the production of plastic bottles, plastic bags, milk jugs and all sorts of food storage, high-density polyethylene is being used. Its counterpart, the low-density polyethylene is used for the manufacturing of plastic bags along with wraps or even the rings which hold your cans of sodas.
Thermoforming is the process by which these plastics are transformed into different products. Via vacuum forming or injection molding a large thin sheet of plastic goes through heat of a specific temperature and then they are forced into molds. This then goes through cooling and any excess plastic being trimmed away but only to be recycled for new thermoformed products. After removing it from the mold, you now have your finished product.
