Address : 1101, 1102, "G" Wing, 11th Floor, Lotus Corporate Park, Off. Western Express Highway, Goregaon (East), Mumbai 400063, Maharashtra, India

3. Preamble to the Description :
The following specification particularly describes the invention and the manner in which it is to be performed.

BACKGROUND OF THE INVENTION:

Horticulture produce is perishable by nature and vulnerable to spoilage due to fungal and bacterial infection. It is also susceptible to damages during post-harvest handling and distribution due to their soft tissues and perishable nature. This leads to significant losses representing financial losses for the farmers, packers, and distributors. For Farmer to get fair and just remunerative price in agriculture value chains, his produce must have lustre and sheen, that is possible if we can decelerate senescence of his produce, thereby increasing marketability.

The currently available methods include ultrafine fibre based products, or old generation platform of active ingredients, use carbon dioxide releasers and oxygen absorbers, Oxygen scavenging, use of external patch to deliver active ingredients, etc.

201811017847 relates to Shelf-life extension film for fresh produce including vegetables, fruits and flowers comprising a plastic film integrally provided with at least one chemical additive and polymer. The film is having thickness of 10-500 microns. The film may be provided with colours/print/holes to reduce moisture accumulation in the bags of film. The film can be formed into sheets, bags, covers or wraps. The storage in the special bags increased the shelf life of Tomatoes, Bananas, Mangoes and rose flowers by 150 to 300% but uses old generation platform of zeolite, permanganates, sodium metabisulfite, carbon dioxide releasers and oxygen absorbers. It does not use latest generation encapsulation technology. This patent mentions Permanganates and Sodium Metabisulfite. Permanganates which have been superseded by newer technology chemicals such those belonging to Cyclopropene family. Sodium Metabisulfite releases Sulphur Dioxide gas, which is also a bleaching agent, and can react with colour of the horticulture produce, which is not acceptable at the market end.

WO2015106342A1 relates to Compositions and methods to encapsulate and control release of volatile organic compounds for increasing shelf-life of perishable products. It provides methods for the encapsulation of volatile organic compounds by formation of stable emulsions of the volatile organic compound that are mixed with encapsulating polymer solutions and then formed into ultrafine fibers. The ultrafine fibers containing the encapsulated volatile organic compounds can be formed into a variety of formats for use to preserve perishable products. This kind of product may not be capable of absorbing ethylene generated by high ethylene producing fruits like banana, extending their shelf life to 60-90 days. Also, 1-MCP is mentioned in this patent, which is very expensive to manufacture or purchase, and largely not feasible on a commercial scale.

2431/MUM/2013 relates to a fiber suitable for packaging. The fiber of the present disclosure comprises a photocatalyst bonded to it by means of a first functional group generated by a surface modifying agent and optionally, a second functional group generated by a silicon containing linker. The chemical bonding between the fiber and the photocatalyst imparts durability and wash ability to the fiber. A packaging material prepared using the fiber of the present disclosure can effectively be used for the storage of plant produce. But the ethylene absorption capacity which is mentioned in the patent may be low for high ethylene generating fruits like mango, banana.

384/MUM/2009 relates to an ethylene adsorbent packaging or barrier material and method of making the same. The packaging or barrier comprises a textile substrate impregnated with a solution of zeolite, cross-linker and binder. The method of making the ethylene adsorbent packaging or barrier material comprises impregnating a textile substrate with a solution of zeolite powder with crosslinker and binder in a solvent at a PH of 5.0 to 7.0 adjusted with an organic acid followed by removing the excess solution from the substrate and drying and curing the substrate at 50-250°C. If desired the substrate is formed to the desired shape. The packaging can be used for packing ethylene susceptible and perishable articles. This kind of product may not be capable of absorbing ethylene generated by high ethylene producing fruits like banana, extending their shelf life to 60-90 days.

US20070207981A1 relates to systems provided for preventing post-harvest fungal diseases of food systems, such as but not limited to fresh produce, such as but not limited to berries (e.g., blueberries). For example, various anti-fungal compounds can incorporated or encapsulated into cyclodextrins, such as but not limited to a, ß and/or ? cyclodextrins. The encapsulated anti-fungal materials can be used alone (e.g., brought into proximity to the produce) or incorporated into film and/or packaging materials that are used in the packing and/or storing of produce. By way of a non-limiting example, the anti-fungal compounds can include volatile compounds such as but not limited to acetaldehyde, hexanal and 2E-hexenal. The cyclodextrins provide controlled release of the volatiles over a period of at least several days such that they prevent or inhibit fungal growth, including but not limited to several species of the Colletotrichum, Altermaria, Botrytis, Penicillium and/or Aspergillus genera. But this is an Anti-fungal technology, with special focus on berries. It does not use ethylene absorbing technology.

It is an object of the present disclosure to provide a Novel Blown/Cast Polymeric Film, Extrusion Coated and Surface Coated/Laminated Kraft paper for packing and storage of Climacteric and Non-Climacteric horticulture produce.

It is an object of the present disclosure to provide a Novel Blown/Cast Polymeric Film, Extrusion Coated and Surface Coated/Laminated Kraft paper that delays microbial and chemical contamination thus increasing shelf life of the horticulture produce.

It is yet another object of the present disclosure to provide a process for making a Novel Blown/Cast Polymeric Film, Extrusion Coated and Surface Coated/Laminated Kraft paper for packing and storage of Climacteric and Non-Climacteric horticulture produce that retains its lustre and sheen by decelerating senescence of the produce.

It is still further object of the present disclosure to provide different ways in which the Novel Blown/Cast Polymeric Film, Extrusion Coated and Surface Coated/Laminated Kraft paper can be used for e.g. the polymeric film can be cut into desired bag sizes, or used in combination with surface coated/laminated Kraft paper to form inner layer of corrugated boxes and cartons for packing and storage of Climacteric and Non-Climacteric horticulture produce to witness decelerated senescence.

SUMMARY OF THE INVENTION:

The present invention relates to usage of novel volatile and thermally challenging chemicals mainly comprising of Zeolite family, Permanganate family, Ferrate family, Cyclopropene family, Vinylglycine family, Nitrogen compound based family, Chlorine compound based family, Ethanol family, Masoprocol family, Fluridone family, ABA family. These volatile compounds are absorbed on a carrier and further encapsulated with a shell to enable their further use in blown/cast polymeric film, extrusion coating and surface coating/lamination of Kraft paper making process to pack perishable horticulture produce.

The main purpose of packaging is to protect the horticulture produce from microbial and chemical contamination, oxygen, water vapour and light. The type of packaging used, therefore, has an important role in determining the shelf life of the produce.

Ethylene is a growth hormone that functions in the sprouting of plant seedlings, the growth of plants, and the growth of fruit. It helps to accelerate ripening in fruit, followed by aging and ultimately death. Ethylene production is a biochemical process, by-product of respiration that occurs in each living cell for the purpose of producing energy.

Ethylene emission differs according to type of plant as well, but high respiration-rate produce is not necessarily a strong ethylene emitter, and vice versa. For example, apples and kiwis do not respire at high rates but do produce large amounts of ethylene. Potatoes respire slowly and emit small amount of ethylene, but asparagus respires at a high rate and produces little ethylene.

As ethylene in the atmosphere surrounding produce increases, the produce's ripening rate increases. If the ethylene level of the surrounding environment is maintained low, ripening slows. The effect on the ripening rate depends primarily on the relative concentration compared to the actual ethylene emission of the produce, rather than on the absolute ethylene concentration.

When ethylene is removed from the fresh fruit or vegetable environment, the ripening and deterioration processes of horticulture produce is slowed, and so the storage life is extended.

The invention is therefore directed to the usage of novel and volatile thermally challenging chemicals that are absorbed on a carrier and further encapsulated with a shell to enable their further use in blown/cast polymeric film, extrusion coated, surface coating/lamination of Kraft paper making process. The polymeric film can be cut into desired bag sizes, with or without perforation, or used in combination with surface coated/laminated Kraft paper to form inner layer of corrugated boxes and cartons for packing and storage of Climacteric and Non-Climacteric horticulture produce to witness decelerated senescence, in turn maintain lustre for an inordinate duration thus relishing superior marketability.
