INTRODUCTION
Polyphone Automatic sealing and cutting machine is a machine that is used simuanously to seal and cut polyphone into different sizes depending on the required dimension. Polyphone is a type of synthetic rubber widely used often as transference sheets for water proof packaging.
Traders in the market require polyphone bags in packaging commodities for their customer. The same material can be made in various shapes as long as packaging of goods is concerned. There is obvious need for diversification of the Nigeria economy. We can start by producing some simple machine so that scare of foreign exchange can be conserved for more need and essential goods.  
It will also enable Nigerians manufacture to expand their industries there by making price of products relatively cheaper compared with the imported ones and at fordable to majority of Nigerians.
Developed countries like Japan started by producing simple machine using the abundant local raw material for the manufacture of goods can also be exported in order to earn foreign exchange rather than exporting the raw material.
There is great need to improve on the technological advancement in the country since, she is blessed with abundant material and human resources which need to be tapped for useful purposed. In plastic industry the machine that are required to process than into usable products can still be manufactured locally. 
This is the more behind the production of this simple machine (Automatic polythene sealing and cutting machine) that will enable the already processed polythene products to be used in many useful ways. Such as parceling and packaging of goods foodstuffs and over in kitchen as a substitute for moi – moi foil.
This shows that the machine is one that is indispensable in the food processing and confectionery industries.
