Abstract

The present invention includes methods for storing polymeric laminate materials, containers made therefrom, and crops and the like.

Description

FIELD OF THE INVENTION [0001] The present invention relates to a polymer film for storing crops, a container made of the same, and a method for storing related crops. [0002]

The present invention relates to polymeric laminate materials, and more particularly to polymeric laminate materials exhibiting functional properties. The present invention also relates to barriers and cushion films that exhibit functional properties that have been proven to be beneficial in the management of adverse conditions associated with barriers and cushion films, particularly food stores, particularly but not limited to these. The present invention also relates to a cushion film wherein the chambers contain the active ingredient to be developed upon contact. The present invention relates to the lamination of cushion films for increased functional properties.

Polymeric laminates that exhibit functional properties have a wide range of applications in many industries ranging from health care to modified atmosphere packaging for structures and the like. For the purpose of the present invention, and more particularly, for food storage, the recent technical advances of flexible packaging and barrier films have led to improvements in water absorption, odor absorption, odor barrier, oxygen permeation and Water vapor transmission management, and the like.

Post-harvest work is not only a significant achievement in human and animal health, but also economic maintenance and overall food security of corporate agriculture and farmers. Poor handling, poor storage, insect attack, fungi, bacteria, fungi and / or other contaminants cause significant health risks when included in the intended food for human or animal consumption. Post-harvest losses from such raids, and more specifically, small farmers in Sub-Saharan Africa, significantly hinder income generation. According to FAO's Paper on Insect Damage, Post Harvest Compendium, "In Tanzania, in case of improper storage, Prostephanus truncatus (Rachel Grain, (Mallya, 1992), loss of up to 60% may occur after 9 months of storage (Keil, 1988), which can lead to a severe famine (Larger Grain Borer) Can lead to ". In Kenya's mountains, the total loss from corn pests is estimated at 57%, and insects are more important than disease (Grisley, 1997). In Zimbabwe, 92% of corn stored in corn was reported to be pest-damaged, and treatment with maltion reduced its degradation by only 10% (Matrio, et al., 1992). Raid rainbow bean raids can be as high as 90% in markets and village vaults (Alabeek, 1996). Extensive food is invaded by insects, and fungal and fungal attack is not limited to corn cobs and legumes. In addition to fungal diseases, pests cause 50% damage in cassava trees (Maninek, 1994). Losses of up to 70% after four months of storage in dried cassava root were reported to be due to P. truncatus (Hodges, et al., 1985).

Pests cause damage to stored products primarily by direct feeding. Some species eat endosperm, resulting in loss of weight and quality, while other species eat embryos, resulting in poor seed germination and reduced viability (Malek & Parveen, 1989; Santus, et al., 1990). In addition to the direct consumption of the product, the insect pests pollute their feeding media due to excretion, excretion, their own survival in carcasses and products, and become commercially undesirable. Damage by insect pests promotes infection by bacterial and fungal pathogens through their infestation (Cravedi & Quaroni, 1982; E. Kundayo, 1988; Dunkel, 1980). The presence of insects also increases the stored product temperature due to their feeding activity, causing hot spots (Appert, 1987; Mills, 1989). These "hot spots" can cause condensation and excessive moisture, which can lead to the growth of fungi or fungi. The activities of insects can have a tremendous impact on the spread of fungal pathogens through which spores pass and the increased surface area susceptible to fungal infections, resulting in increased production of mycotoxins (Dunkel, 1988).

Despite the physical damage of pests, raids due to poor storage after harvest have had a tremendous economic impact on the economies of several nations and ultimately on international food security, with farmers, communities and exports of corn, wheat and other foods . For example, P. truncatus sacrifices roughly $ 91 (US dollars) annually in the loss of corn intended for consumption or export in Tanzania (Bionet International & Global Invasion Species Program). Farmers in Sub-Saharan Africa often forcefully sell products that are too early to be stored, due to the damage caused by the damage caused by extended shelf life (Global, et al. 1996, Brice et al. 1996, Marsland &Amp; Golob, 1996, Donaldson, et al., 1996). Post harvest retention and inability to protect can lead to significant revenue declines as farmers do not have the flexibility to wait for higher prices as markets fluctuate. The combined difficulties of food storage and the economic burden of post-harvest losses on farms are not only limited by the lack of available resources to build insect and rodent containment units, lack of information related to pesticide / pesticide use, Due to the lack of purchasing capacity for materials that can mitigate climate conditions, it is damaging to farmers in developing countries.

On-farm storage Difficulties and post-harvest losses are mainly due to the lack of oxygen permeability and water vapor permeability of currently used storage vessels, causing temperature, humidity, respiration of stored contents, insect attack, Fumonisin, mycotoxin and aflatoxin due to fungus and fungal growth. Contaminated product contamination presents a serious health hazard when intended for human consumption or used as animal feed. Aflatoxins consumed by dairy cows change their bodies, but are still toxic and show an increase in milk (Christensen & Meronuck, 1986, Gwinner, et al., 1996). Aspergillus A. fumagatis results in a high level of abortion in cows fed the contaminated feed; It has also been reported to infect human lungs (Darwish, et al., 1991; Pandey & Prasad 1993; Abud, et al., 1995).

The use of plastic bags, bag storage, prefabricated iron halls and flexible plastic silos has shown an increase among farmers for short-term storage (Peterson & Simila, 1990; Compton, et al., 1993; Bartali , 1994). However, none of the current storage mechanisms have been used to control humidity, the barrier to effective permeation of oxygen, and more specifically, to control insects and / or rodents and / or humidity control and / Including contact release mechanisms for active ingredients that promote desirable effects such as, but not limited to, antimicrobial properties, antimicrobial properties, and the like. ≪ RTI ID = 0.0 >

Therefore, in order to obtain optimal storage conditions for prevention and reduction of post-harvest losses, there remains a need for improved polymeric materials for maintaining moisture levels and dry farm food storage on acceptable, FAO recommended stored products have.

There remains a need also for effective administration of pesticides or pesticides within a laminate structure such as that used in food containers.

Influence of external temperature and humidity on moisture penetration and subsequent moisture accumulation in the surface layer of grains adjacent to the innermost layer of the container and subsequent storage of the product atmosphere, which makes conditions for fungal, fungal and bacterial contamination, and aflatoxin, There are a number of additional problems associated with farm storage of dry food such as toxins and resultant toxins such as fumosin and the like (e.g., cereals and corn).

Separate storage units for packaged agricultural products are subject to both insect and rodent raids. Insect raids can worsen fungal growth and fungal growth due to respiration, excretion, and penetration of insects and the distribution of fungi, fungi, and bacterial spores, while migrating through stored products. It is therefore advantageous to provide a farm storage container that prevents or reduces attack and manages water permeation to inhibit fungal growth. In order to reduce fungal growth, the container allows the form of sealed storage with the use of the novel substrate described in detail herein as an element of complementary water vapor diffusion or sealing approach, so that the polymer layer retains moisture or functionality, To achieve a certain degree of oxygen permeability in such a way as to prevent moisture accumulation and its associated effects, such as hot spots, and areas that corrode food due to concentrated water, by achieving a difference in the external and internal temperatures and relative humidity of do.
