A Brief Introduction
Due to the ever increasing usage of non degradable plastics in day to day life, and due to the environmental/pollution hazards faced due to its non degradable characteristics, this research was undertaken to make polyethylene totally biodegradable. Enhancing polyethylene products to undergo a change in its chemical structure under environmental conditions. The loss of properties of polyethylene while contacting with soils and water may vary as measured by standard list appropriate to plastic and the application in a period. Our biodegradable product enables polyethylene (HDPE and LLDPE) to biodegrade in atmospheric conditions in soil and compost thereby releasing CO2.
Applications : Accessories for flower arrangements, bags, boxes, horticultural films (mulch Films), nets, packaging, packaging films, packaging material for mailing, planters, planting pots, sacks, shopping bags, straws, strings, tableware, trays, wrap film.
Myths of Packaging
Packaging is an unnecessary & harmful extravagance.
The fact is that our modern lifestyle demands packaging material for nearly everything we buy to protect and preserve the goods. Packaging prepares goods for transport, distribution, storage, sale, and use. This is to be done in the most cost-effective way. Thanks to packaging it is possible for products to be available anytime, anywhere, which gives the consumer a great freedom of choice. Good packaging reduces waste. Without packaging a great proportion of our foodstuffs would have a shorter shelf life and would not reach the consumer in a fit condition. Famine in less-developed countries may not be due to shortage of food but of adequate packaging of existing resources (food waste in Western Europe is 2-3% while it is 30-50% in developing countries).
Demands on packaging
The demands on packaging are high. It should be:
- good for you the consumer .
- good for the product by protecting it
- good for the environment when manufactured and disposed.
Packaging is not a recent phenomenon. Even in ancient times, packaging was being made from a wide range of materials such as clay, wood, glass and metal. Over-packaging does exist, however, and should be dealt with when there is no justification for it.
Packaging is not something I need to bother about.
As consumers we can have a strong impact on the packaging industry. Our choices when purchasing goods demonstrate what we like, which works as a guidance to the packaging industry. If better informed we can improve our choices.
We do not need so many different types of packaging.
We may well need most of them. Packaging is a complex endeavor, where an extremely wide range of needs is to be addressed. The first consideration is the nature of the product, which is to be protected/preserved, and product types vary hugely. Among other considerations are raw material (cost and availability), available machinery, strength of the packaging material during transport, tampering, attractiveness to consumers, and environmental and legal issues.
Test product – Evergreen Bio-technology
Evergreen Bio-technology product for a completely new, plasticizer-free thermoplastic material. Evergreen Bio-technology is extremely suitable for blown film extrusion, sheet film extrusion and injection molding of completely biodegradable products. The complete biodegradability and other functional properties enable the converter to advance in production areas, which could not be reached with traditional thermoplastic materials. 2. Properties
