Carboys & Jerrycans manufactured by us have been
developed over a period of time after analysis of the drawbacks of drums
currently on the market and considering specific requirements arising
out of Indian market conditions. The drum developed therefore is a user
friendly package, with optimal handling qualities suitable both for
mechanised and manual operations. Details are as follows:
1) Nature of Material:
The material used in the manufacture of this product is prime virgin
High Molecular Weight/High Density Polyethylene (HMW/HDPE) granules.
The Carboys and Jerrycans are of Co-extruded Multi Layer (Double) Construction
Uncoloured virgin HMW/HDPE granules are used for the inner layer and
coloured or carbon black filled virgin HMW/HDPE granules are used for
the outer layer. The carbon black filled outer layer ensures protection
of packed material from UV radiation, while the uncoloured inner layer
ensures purity of sensitive materials.z
2) Method of Manufacture:
These containers are blow moulded on fully automatic co-extrusion blow
moulding machines with parison programming for wall thickness controls.
The products confirm to the Indian Standards specification IS-6312 and
the UN standards to obtain IMDG code for exports of hazardous products.
The specified tests include;
(1) Drop Test : Height 1.2 metres
(2) Stack Test: : Upto 2 metres.
(3) Closure Leakage Test. :
(4) Hydrostatic Test. : @ 1.1 kgs / cm2.
(5) Environmental Stress Crack Resistance (ESCR) Test. :
(6) Compatibility Test :
In addition another recommended test is the Transition test to test
the effect of Plastics with the packed product and its transition into
the same. The same test are also prescribed for UN certification to
obtain the IMDG code for packaging and transportation of hazardous materials.
Prior to despatch, the finished products are tested for Drop, Stack
and Closure Leakage tests.z
3) Cost of the Package:
The cost of the carboy is relatively high because of the high cost of
basic polymers. As the carboys are REUSABLE they can be used over and
over again thereby leading to a REDUCTION in packaging costs.z
4) Methods of filling, closing and opening:
These containers can be Hot filled on conventional manual filling lines,
as well as on automated equipment. A significant feature of our products
is incorporation of Tamper proof & Sealable sealing rings on the
closures, which have to be broken to gain access to the contents. These
can be personalised with users logos and code numbers to further ensure
tamper proofing. Few carboys and jerrycans are also designed with Pilfer
Proof Caps to prevent theft and misuse. Closures are leak proof and
tested at our works prior to despatch of finished products.
5) Nature of Transport system for which products
are suitable:
Carboys & Jerrycans are extremely light weight and can be stacked
after packing. They are designed for mechanised handling. Apart from
normal fork-lift operations, recessed handle in the dome or side handles
facilitates manual handling and lifting by cranes or pulley arrangements.
Stiffening ribs have been incorporated in the drum for ruggedness under
adverse conditions, which arise in transport. Care has to maintained
at the time of transportation of liquids and viscous material to ensure
that the drums are not punctured due to bad or mishandling of the same,
as it will result in loss due to leakage of packed materials.z
6) Significant features of the Package:
a. Protection: Niranjan's carboys & jerrycans are co-extruded
with an outer layer protecting against degradation by UV radiation,
and an inner layer ensuring purity of the packed material. HMW/HDPE
- which is the material of construction provides excellent impact resistance
and is inert and impervious to attract by most chemical agents. Further,
these drums are airtight and waterproof.
b. Visual Appeal: These containers have excellent visual appeal, can
be effectively screen printed, thereby promoting and enhancing products
and user identity.
c. Convenience: Niranjan’s carboys & jerrycans are stackable,
hence minimizing floor space requirements. They are easy to fill and
empty and can be handled both with mechanical and manual means. The
package size also allows optimal stuffing into standard shipping containers
for export purposes.
d. Originality: This package is original inasmuch as it its unique design
permits the use both of mechanised and of manual handling. We understand
this is also the first time a container of this size has been manufactured
in Co-extruded Double Layer construction.
e. Construction: Co-extruded blow moulded construction with a coloured
outer layer provides UV resistance or visual appeal as required and
an virgin uncoloured inner layer ensures purity of contents. z
7) Overall Packaging Economies:
HDPE packaging has been found to be extremely economical as the packaging
can be reused many times over and over again thereby leading to a considerable
reduction in packaging cost. When resold the products give an excellent
and high resale value.+
