INTRODUCTIONINTRODUCTION

INTRODUCTION

Plastic containers are replacing conventional metal containers and glass containers

because of their comparatively better properties and ease of handling and

transportation. Small size plastic containers are used for packing of drugs,

pharmaceuticals, insecticides, food items etc. The plastic blow moulded containers are

made from HDPE, HMHDPE, LDPE, PP etc. Blow moulded plastic containers are finding

great demand in modern era. With latest trends in Blow Moulding technology and

advanced machinery and National and International standards moulds and dyes,

many types of packaging containers are manufactured with accurate tolerance and

fine quality. These products includes Pet bottles, Dropper bottles, Upper Handle

bottles, Open top drums, wide mouth drums, Narrow mouth drums, Barrels, Jerry

Cans & Carboys, Square Jars, Round Jars, Rib Jars, Thin walled food packaging

containers etc. They are of different types and designs that are manufactured to cater

the need of packaging.

6

Page 7: 38214028 Project Report Plastic Moulded Jerry Cans

With high quality raw materials procurement, blow moulded articles and containers

are manufactured with superior quality associated with convenient shapes and sizes,

Strong and Sturdy construction, Compact designs, Compatibility, Safe to use etc. As

there is very good demand for plastic containers of various sizes and shapes, I am

planning to set up this unit with assurance of that this is a profit oriented trade.

Though there are lot of products can be manufactured by blow moulding technology,

Initially, I am planning to manufacture only Jerry Cans of 1 Lt, 2 Lt, 2 ½ Lt, 5 Lt, 10

Lit and 20 Liters filling capacity. I would like to maintain the following in order to

fulfill the needs of our clients and consumers and I hope I can capture good market.

Strong and Sturdy: The products are made out of special grade High

Molecular - High Density Polyethylene (HMHDPE) or High Density Polyethylene

(HDPE) with excellent strength to withstand all transit hazards in any

conditions.

Standard Designs: it includes wide range of latest & standard designs in

packaging products to provide the client or end user with latest innovative

designs and products with ease in handling to provide with complete bulK

packing solutions.

Compatibility : The material used in production i.e. High Molecular High

Density Polyethylene is of food grade (certified) and compatible with food

chemicals, petroleum products, hazardous chemicals, Resins etc.

Safety : The products goes through with multiple tests to pass all of them

and use certified virgin raw material only to give you the complete packing

solution.

Packaging Standards: The products are also confirms national and

international packaging standards and are listed with IIP (Indian Institute Of

Packaging) to provide you UN Certification and other testing requirements.

Price: Believing in right & fair price policy, in which we are ready to share

information to make the customer or end user comfortable about on their

purchasing decisions.

BASIS & PRESUMPTIONS

The Production is considered on single shift basis and the working days in a

month are 25 and that of per annum is 300.

The Installed Capacity of the unit is 200 Kg per shift. It is decided to

manufacture 3.5 tons (140 Kg per Day) of raw material i.e HDPE Granules is

processed to manufacture Jerry Cans of different shapes and sizes. The time

period for achieving full/ envisaged capacity utilization is three years.

Though the unit is run with Blow moulding technology, many types of plastic

articles and household items can be manufactured. But, Initially, Jerry Cans

of 1, 2, 2 ½, 5, 10, 20 Liter Capacity would be manufactured in the proposed

unit.

8

Page 9: 38214028 Project Report Plastic Moulded Jerry Cans

Out of total production, 20 % of 20 Liter, 15 % of 10 liter, 15 % of 5 Liter, 20

% of 2 ½ Liter, 20 % of 2 Liter, 10 % of 1 Liter capacity Jerry cans are

manufactured.

The weight of 20 Liter Jerry Can is 1000 Grams and that of 10 liter Jerry Can is

500 Grams, 5 Liter Jerry Can is 200 Grams, 2 ½ Liter Jerry Can is 110 Grams,

2 Liter Jerry Can is 90 Grams and 1 Liter capacity Jerry can is 50 Grams.

Wastage in the Raw materials and process losses has been considered at a

rate of 2 %.

The final products are marketed with a brand name i.e TOUGH PLAST. For

this, multicolour stickers are pasted on the can. These stickers are from third

party. The cost of each sticker is sack is 50 paisa with roto gravure printing.

The salaries and wages for staff and labour have been taken into consideration

as per the Minimum Wages Act.

Economics have been worked out with out the subsidy (35% on Total Capital

Investment under PMEGP Scheme) component. With the subsidy its viability

will be much better.

The cost of plant and machinery, Raw materials, selling price of finished

products etc. are the prices collected at the time preparation of project report

and may vary depending upon location, manufacturers, market and other

various reasons.

Interest on term loan has been taken at the rate of 12% on an average. This

rate may vary depending upon the policy of the financial institutions/agencies

from time to time.

PROCESS OF MANUFACTURE

Blow moulding follows the same stages of manufacture as injection moulding. HDPE

(high density polyethylene) is ideal for this type of manufacturing technology. The

steps in the formation of any container (the die is changed for each product and

specific design) are…

1. The plastic is fed in granular form into a 'hopper' that stores it.

2. A large thread is turned by a motor which feeds the granules through a

heated section.

3. In this heated section the granules melt and become a liquid and the

liquid is fed into a mould.

4. Air is forced into the mould which forces the plastic to the sides, giving

the shape of the bottle.

5. The mould is then cooled and is removed.

LOCATION OF UNIT

I am planning to start the unit besides NH 5 Nearer to Narasannapeta town of

narasannapeta Mandal of our District. The proposed location is quiet besides the

Golden Quadrilateral National Highway (NH-5) and is very accessible to all modes of

transport facilities. As Narasannapeta is one of the trading points in the district, many

transport operators are running franchisees here. It allows us easy transportation of

Raw Material as well finished goods. Concerning with Government friendly decisions

towards entrepreneurship development, there are so many concessions and subsidies

are offered particularly to SSI sector. By starting this unit at this location, I can avail

subsidy of 35% on total project cost, under Prime Minister’s Employment Generation

Programme (PMEGP).

QUALITY CHECKING TESTS

1. DROP TEST

For testing purpose, each drum was filled with their capacity of water and closed by

Plastic Plug (Insert) and further with P.P. (auto seal) Plastic Cap.

Full Open Top Drum filled with their capacity of sand and closed with plastic lid

provided with rubber gasket and lid was reinforced by metallic lever type ring closer.

First time, drum is dropped diagonally on top.

Second time, drum is dropped flat on body wall.

Third time, drum is dropped on bottom.

Fourth time, drum is dropped diagonally on bottom corner.

2. STACK LOAD TEST

For testing purpose, filled drums were stacked one above the other (1+2 drums)

for a period of 24 hours and one lot for 30 days.

3. CLOSURE LEAKAGE TEST

For testing purpose, filled drum was kept upside down on the floor for one hour.

4. HYDRAULIC PRESSURE TEST

For testing purpose, hydraulic gauge pressure of 1.1 Kg./Cm2 was applied inside the

drum for a period of 5 minutes.

pressure

c) Parts sticking in

mould

a) Adjust knockout stroke for

longer movement

design if necessary

11 Excessive

shrinkage

12 Parts blow-out a) Blow-up ratio too

large

b) Mould separation

c) Pinch-off too sharp

d) Pinch-off too hot; no

weld

e) Parts blow too fast

a) Use large die

b) Increase clamp pressure

or decrease blow pressure

c) Provide wider land in

pinchoff

d) Cool Mould pinch off

e) Use low-pressure blow

followed by high-pressure

blow13 Parison tail

sticking to parts

a) Parison too long a) Shorten parison length or

increase pinch-off land area to

cool compressed tail.
