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.
Put aluminum alongside tinplate steel and you'll find it with more advantages starting with it being less costly and can be made easier though it still resists corrosion. This is the metal that is the most abundant type on Earth. In addition, aluminum can be recycled an infinite amount of times to create new cans and products. In fact, about two-thirds of all aluminum ever produced is still being re-used today. This number would be higher if people would simply remember to place aluminum into their recycling bins.
Take a look around and surely you'll find plastic to be the most commonly used material for packaging. Even when you look inside those products you see with cardboard boxes you will find the foods are wrapped in waxy plastic bags, such as cereal, cookies and crackers. A resin code, typically identified by a number in a triangle, will tell you which type of plastic was used for your plastic packaging.
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.
