Protection from foreign particles entry; the products are protected from entry of oxygen, dust, bacterial, viruses, water, chemicals and other harmful agents that may destroy or degrade the working parts.
Agglomeration: through packaging, small objects are grouped together to form one package. Packaging eases the process of transport, warehousing and distribution. Products like liquids, powders, air and chemicals are easily handled when packaged.
There are many types of packaging materials that are commonly used. These materials differ from product to product and are also affected by the mode of transportation, costs, warehousing, customer's demands and many other factors. In the recent past, great concerns have been put forward by the environmentalist regarding the pollution by packaging materials. Most packaging materials are discarded once the product reaches the customer. This has significant effects on the dumping and pollution especially if the packaging material is made of plastic or glass or any other non degradable material. This has resulted to the introduction of recyclable packaging materials, materials reuse and use of biodegradable plastics. Consequently, symbols of quality, recycling symbol, the green dot symbol have all be introduced on the packaging materials. ...
Consequently, symbols of quality, recycling symbol, the green dot symbol have all be introduced on the packaging materials. This papers studies packaging materials for lighting applications, their effects to the environments and also studies which of the materials are recyclable and environmentally friendly as well as the current techniques used to improve packaging to prevent dumping and accumulation of these materials in landfills.
Types of lighting application
There are many types of lighting applications these include;
Compact fluorescent lights (CFL)
