What are the Different Types of Materials Used for Packaging?

The basic purpose of the packaging is to hold the products safely without damage and to prevent breakage and leakage. In the cases of food packaging, the aim of appropriate packaging is to protect the food from germs, moisture, heat etc. The entire packaging can be categorised into two basic categories, namely retail containers or packaging and the shipping packages or containers. The retail packaging basically protects food as well as other products. The retail packaging also serves the purposes of advertisements for the growth of business and promote the brand.

There are different types of packaging depending upon the technical needs and market requirements.

Often, the paper is extensively used for packaging because it is less expensive and holds the shape perfectly, and you can decorate the paper easily. The paper that is commercially available is manufactured from cellulose fibre from the pulped wood. However, paper can be manufactured from other materials straw, cotton, hemp and sisal. The recyclable characteristics of paper make it eco-friendly and popular for packaging. The paper and board are normally measured by the weight or calliper. The material which is less than 250 grams in weight for per square meter or gsm is called a paper, and the material that is 250 gsm is called paperboard. The papers are also laminated to increase their strength.

The glass is another material extensively and popularly used for packaging. These glasses are made out of silica, calcium carbonate and sodium carbonate. In order to give colour, heat and shock resistance other ingredients are added during manufacturing the glasses. The packaging with glass is beneficial because the glass is gas and moisture resistant, and pressure-resistant up to some extent, and can be moulded to give different shapes. The glass is also inert, sterilisable and above all transparent so that the product is visible. Besides the paper and glass, there are other materials which are used for packaging such as metal especially tin or aluminium, plastics, LDPE or low-density polyethylene, polypropylene, polyethylene terephthalate, polyvinyl chloride etc.
