Different Packaging Options For Your Food Product

By Lenna Stockwell


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.

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.

These plastics are transformed into products through a process known as thermoforming. Large, thin sheets of plastic are heated to a specific temperature and then forced into molds either using injection molding or vacuum forming. Once the plastic has cooled, the excess plastic is trimmed away and recycled to make new thermoformed products. The finished product is then removed from the mold.
