INTRODUCTION

2. Plastics are widely used because of theirlight weight nature,
durability, potential for diverse applications and low price.
i. Hygienic –inert and chemical resistance
ii. Light weight and non-breakability
iii. Excellent barrier properties - enhancing shelf-life,
iv. Superior impact resistance,
v.Sterilizable and resistance to bacterial and other microbialGrowth,
vi. Transparencyaswellas opacity.
WHY PLASTIC USE?

3. A.RECYCLABLEPLASTICS
(Thermoplastics):
PET,HDPE,PVC,LDPE,PP
,
PS,etc.
B.NON-RECYCLABLE
PLASTICS
(Thermoset&others):
Multilayer &Laminated
Plastics, PUF
, Bakelite,
Polycarbonate, Melamine,
Nylon etc.
