Packaging

From gift boxes to cake boxes, packaging is an essential part of the modern world. Packaging come in different materials. Aside from paper and cardboard, you will also see many packaging made of glass, metal, plastic, and wood. They also come in a great variety of shapes and sizes. Some are designed for shipping, some for warehouse storage, and others for holding hazardous materials.

Paper cartons and cardboard boxes are the most widely used materials for packaging. They are used to contain food, tobacco products, and detergents.  They are also used for numerous household appliances, television sets, toys, and other large items. The rectangular shapes of cartons are meant for convenient storage.

Many packaging, especially those containing food, are lined with thing plastic, metal-foil, or waxed-paper for better durability and protection. Some linings provide insulation to protect either the product from external temperature, or the customer from hot items. In some larger cartons the unfilled space around the product may be packed with light pieces of plastic to prevent damage to the contents during shipping and carrying.

The most recognizable metal package is the cylindrical tin can that opens at the top. These cans are used mostly for processed foods, beverages, paints and varnishes, some cosmetics, and a few tobacco products. Contrary to their name, tin cans are usually made of aluminum or steel. In the case of steel cans, a thin plating of tin may be used to protect the steel from reacting with certain chemicals. In some cases, a coat of lacquer or plastic is used instead. Most cans are round, but rectangular shapes are occasionally used for larger package to help save storage space requirement.
