DESCRIPTION

Description of the industrial invention model entitled:

"Micro-perforated paper bag to protect the fruit from parasitic agents",

TEXT OF THE DESCRIPTION

Brief outline of the essence of the invention.

This is a parchment paper bag, equipped with special microperforations for ventilation, which once affixed to the fruit on the plant (eg peaches) during the entire period from swelling to ripening. it allows to perfectly protect them from parasitic agents without resorting to any type of chemical phytosanitary treatment, and to improve their qualitative characteristics, real description.

The bag is in parchment paper with a base weight of 35 g / m2 (or 30 g / m2, or 37 g / m2, or 40 g / m2) with a tensile strength of no less than 34N, certified DIN, EN, IS09002, transparency of not less than 82% in the light, glued with glue suitable for food use in compliance with the provisions of the EEC directives and the implementation decree n.155 of 26/05/97. and near the line of the bottom edge and in part of that of the two lateral edges, it has micro-perforations with a diameter of 1 mm each and ribs at a distance of 2 cm from each other. The external dimensions vary according to the size of the fruits and -are;

N. Width Height

1. 21cm 23cm

2. 20cm 22cm

3. 19cm 22cm

4. 18cm 22cm

All the fruits, especially those whose fruiting and ripening period corresponds to the period close to the summer season, are subjected to strong pressure from parasitic agents, such as fungi, insects. bacteria, mites, etc. These, in the absence of rational and energetic defense strategies for their containment, irreversibly damage the fruits making their marketing impossible.

Generally farmers' to defend the productions in progress, use toxic chemicals that they distribute through repeated phytosanitary treatments on the plants and therefore on the fruits for the entire production cycle. The repeated use of these products determines, at the time of collection, the presence on them of chemical residues which, even if lower than the minimum required by current regulations, contrast with the tendency of consumers to increasingly prefer products obtained using techniques with low environmental impact. respectful of human health and the environment. The protection of the fruits by "bagging" places a mechanical barrier to the most common animal and vegetable parasites (Fruit Fly, Cidia, Anarsia, Fumaggine, Monilia, etc., thus allowing producers to be able to defend the Tri act productions on plants perfectly , without using any type of chemical product throughout their growth and maturation cycle. the products marketed fi "Sùltano are thus totally free from any trace of chemical residues. Another purpose of the bag is to protect the fruits from excesses of environmental humidity , especially in late summer-early autumn productions, which cause the blackening and decay of the fruits (Fumaggine, Monilia spp., etc.) and to favor the expulsion of the humidity formed inside thanks to the microperforations of ventilation present on the bottom and part of the side edges.

Finally, the high transparency of the paper that makes up the bag, not less than 82%, creates a moderate greenhouse effect inside, causing the fruits to achieve a significantly more intense color, much appreciated by consumers.

This technique has already been in use for several years in the farms of some farmers, in particular in areas where the cultivation of late ripening peach orchards (ripening from the second decade of August to early November) and table grapes is underway, relatively to the which, the use of the bag, allows to defend the fruits from parasitic agents for their entire period of enlargement and ripening. The bags used, however, are made of various non-specific materials, without any micro-perforations, with transparency defects that do not allow a correct gaseous exchange with the outside, packaged with glues or materials not specific for food, with mediocre resistance to mechanical stress {wetting, weight of fruit, etc.). The result is that the production costs compared to the bag described are higher, both directly in terms of excessive manuality for its realization, and indirectly in terms of excessive loss of product in the ripening phase (waste deriving from high quantities of fruits affected by parasitic agents, defects in color and stains on the surface of the fruit). The proposed bag will therefore allow to continue to maintain and further spread this method of mechanical defense, being made with highly technological materials and techniques designed to purify the "bagging" method from defects up to now found, which have so far limited its diffusion.
