FIELD OF THE INVENTION
The present invention relates to a package for packaging of reactive material and more specifically related to a package for long shelf life of product and offering convenience to consumer.
BACKGROUND OF THE INVENTION
For many years, products such as moth, insect repellant and room fresheners have been individually packaged in conventional form, fill, and seal in a paper or cardboard packaging material. The said products are highly reactive and react with packaging material as well as printing inks which during storage adversely affect the quality of product as well as package.
The reactive materials include para dichlorobenzene (PDCB) used in household as air freshener, moth and insect repellant etc. The para dichlorobenzene is very aggressive and reactive material and requires a lot of precaution for handling it. The packaging of PDCB also requires a lot of precaution and use of compatible material for packing. However the cost of such packaging is high as well as the material used in packaging get deteriorated during the use.
Therefore there is a need for a package and packaging material which can offer convenience and extend the shelf life of the package and at the same time being economical viable so that the cost of product is ultimately minimized.
SUMMARY OF THE INVENTION
The present invention is directed to a product package more specifically to a flexible package that will protect and package from ambient environment and maintain the quality of product.
In accordance with an embodiment of the invention there is provided a package comprising a body initially closed by resealable flap at one end in the region intended to be opened for use, the body comprising at one main face formed one section of film whose longitudinal edges are bonded to each

other along a longitudinal seal lying along the height of the body substantially the lateral part of the main face, at least one of the section extending outside the body beyond the longitudinal seal in order to form a flap characterized in that it further comprises a resealable part and a hanging portion.
According to another embodiment of the invention there is horizontal seal at least on two sections in the body. The first seal is preferable at the bottom, second near the top portion and third at the top edge of the package. The said sealing on prescribed position make the two compartment, large one for product storage and small top portion for hanging etc.
According to another embodiment of the invention the top portion seal is lying in between the bottom portion of the next package. The horizontal seal between two adjacent packages also provided with tear dotted line for easy detachment of the package for use.
According to an embodiment of the invention there is provided a package which is attached to another package longitudinally and makes a string of package to enable a retailer to store or hang the product to enhance display.
In accordance with another embodiment of the invention there is provided a flexible packaging film of at least one BOPP film and at least one opaque white pearlised BOPP film, which is reversed printed using the polyamide based ink by conventional printing technology.
According to an embodiment of the invention there is provided a polyamide based ink for printing of packaging material which is resistant to alkali, soap, hardeners and chemicals.
According to another embodiment of the invention there is provided use of a polyamide based ink for printing of packaging material offers long shelf life to the package.
According to another embodiment of the invention there is provided a package having a definite size of holes on the face of package to facilitate the evaporation of PDCB from the holes after opening.
According to another embodiment of the invention there is provided a process for packaging of PDCB blocks in heat sealable metalized polyester (HSMET PET).

According to another embodiment of the invention there is provided a package which is suitable for packaging of aggressive and reactive material like PDCB and the like.
According to another embodiment of the invention there is provided a package which is economical due to the low cost of manufacturing and extend the shelf life of the product.

DETAILED DESCRIPTION OF THE INVENTION
Referring to the figure in general and to fig 1 through 4 in particular, one embodiment of the invention is directed to product package. The package, shown generally as 100 comprises a flexible product wrapper 110. Again, it should be understood that while a product package is specifically described herein, other product package that can be commercialized are within the scope of the present invention.
The product wrapper 110 is formed from a generally rectangular singular sheet 109 of flexible film having opposite end 111 that define the length of package and opposite sides. The sheet 109 includes a main portion 108 and a marginal area 107 which forms the seals after the package is formed. The package formed therefrom includes a front wall 114 and a rear wall 115 opposite side edge 119 and a width. To seal the product inside the package wrapper 110, a lower transverse seal 116a and upper

transverse seal 116b extends across the width of the package. A Longitudinal seal 117 extends lengthwise between the opposed ends to enclose the film. A resealable area 118 is left out after permanent sealing of longitudinal and transverse seal.
In the first embodiment shown in fig 1 through 4 the continuous sheet 109 of flexible film is formed from pearlised BOPP, oriented polypropylene, cellophane, polyester or the like film material. As will be appreciated, the continuous sheet forming the wrapper 110 to cut from a large roll during the actual assembly line packaging process. Such packaging assembly equipments is available from any number of packaging machine manufacturers. The resealable area 118 containing a gum having self adhesive properties and which can be seal and reseal and can be used for many times.
The permanent sealing can be done on transverse 116a and 116b as well as longitudinal seal 117 by any suitable sealing method e.g. ultrasonic sealing.
In an embodiment shown in fig 2 the sheet is closed on both the ends 116a and 116b and 117, and another sealing at 201. The sealing on prescribed position forms two compartments, first is a product holding section 111a and second, the hanging and information part 111b. The section 111b bearing at least two cut 124 such that they can be superimposed during the folding of 111 from the middle part to make one cut finally. The said cut can be used to hold the package or used for hanging of the package. In a similar way the product holding section also contains a number of cuts of various shapes 125 which will make the product holding section 111a ventilated.
Fig. 3 is displaying a front side of package containing the product 301 in product section 111a having superimposed ventilated openings of various shape 125 and hanging section 111b in which the superimposed hanging section 124.
Figure 4 is reflecting a rear side of package containing product 301. The resealable part 118 is in closed position. Any end user can withdraw the product from the package from the resealable side by opening it and again insert the new product from the said side for further use and seal the resealable part 118.
The flexible packaging film disclosed is of at least one BOPP film or selected from pearlised BOPP, oriented polypropylene, cellophane, polyester or the like film material which is reversed printed using

the a formulated polyamide based ink by conventional printing technology. Said ink for printing is polyamide based ink for printing of packaging material which is resistant to alkali, soap, hardeners and chemicals which can offer long shelf life to the package.
The product may be selected from para dicholoro benzene, other reactive compound, air freshener; moth repellant etc. the said products blocks of various sizes is packaged in heat sealable metalized polyester (HSMET PET).
The package as disclosed herein is suitable for packaging of aggressive and reactive material like PDCB and the like. The package is also very economical due to the low cost of manufacturing.
It should be recognize that the preferred embodiment described above is exemplary only. Certain modifications and improvements will occur to those skilled in the art upon a reading of foregoing description. It should be understood that all such modifications and improvements have been deleted herein for the sake of conciseness and readability but are properly within the scope of the following claims.
