ADHESIVES |
|
An adhesive is a compound that adheres or bonds two items together. Adhesives may come from either natural or synthetic sources. Some modern adhesives are extremely strong, and are becoming increasingly important in modern construction and industry.

PACKAGING and LABELLING |
|
Packaging is the enclosing of a physical object, typically a product that will be offered for sale. Labelling refers to any written or graphic communications on the packaging or on a separate label.
The purpose of packaging and labels
Packaging and labeling have five objectives:
Physical protection of the object - The objects enclosed in the package can be protected from damage caused by physical force, rain, heat, sunlight, cold, pressure, airborne contamination, and automated handling devices.
Agglomeration - Small objects are typically grouped together in one package for reasons of efficiency. For example, a single box of 1000 pencils requires less physical handling than 1000 single pencils. Alternatively, bulk commodities (such as salt) can be divided into packages that are a more suitable size for individual households.
Information transmission - Information on how to use, transport, or dispose of the product is often contained on the package or label. An example is pharmaceutical products, where some types of information are required by governments.
Marketing - The packaging and labels can be used by marketers to encourage potential buyers to purchase the product. Package design has been an important and constantly evolving phenomenon for dozens of years.
Reducing theft - Some packages are made larger than they need to be so as to make theft more difficult. An example is software packages that typically contain only a single disc even though they are large enough to contain dozens of discs.

PLASTICS |
|
Plastic covers a range of synthetic or semisynthetic polymerization products. They are composed of organic condensation or addition polymers and may contain other substances to improve performance or economics. There are few natural polymers generally considered to be "plastics". Plastics can be formed into objects or films or fibers. Their name is derived from the fact that many are malleable, having the property of plasticity. Plastics are designed with immense variation in properties such as heat tolerance, hardness, resiliency and many others. Combined with this adaptability, the general uniformity of composition and light weight of plastics ensures their use in almost all industrial segments.
