Embodiment

[0078] The following examples are given to describe the present invention in detail, but the present invention is not limited to these examples.

[0079] In this example, as shown in Table 1, a 25 μm thick transparent OPP film is used for the main body of the bag, and the transparent OPP film is provided with holes of 1,786,000 / m on the entire surface of the film 2 , The average pore diameter is 100-130μm, and the average pore area ratio is 1.4%. The air-permeable micro-pores are composed of circular holes. The light-scattering member is provided on the entire surface of the film by ventilating holes with a pore diameter of 1 mm at a pitch of 8 mm. It is composed of a milky white and translucent high-density polyethylene (HDPE) film with a thickness of 20 μm and added with 1 to 3% white coloring agent.

[0080] According to the manufacturing method of one embodiment, a desired fruit protection bag is obtained.

Abstract

The invention provides a fruit protection bag which can be covered on fruits such as grapes, pears, apples and the like to protect the fruits from being damaged by birds or sunburn. The fruit protection bag comprises a bag main body made from a transparent or semitransparent thermoplastic resin film and a light scattering part made from thermoplastic resin, wherein at least two side edges of the bag main body except for an opening part are melted and covered; the whole surface is provided with a plurality of venting pores; and the light scattering part is folded on either side or two sides of the back surface of the bag main body and is melted and covered on two side edges close to the opening part in a stripping mode. The fruit protection bag further comprises a tightening installation part, and the tightening installation part consists of one of a raised tightening rope, a tightening installation piece or a tightening metal wire, wherein the tightening rope is melted and covered close to the opening part of the bag main body, is used for tightening the bag main body on a support branch part, is provided with a clamp bulge and is made from thermoplastic resin; the tightening installation sheet is made from the thermoplastic resin; and the tightening metal wire is covered by the thermoplastic resin. The light scattering part is formed by mixing the thermoplastic resin with one of white colorant, pearl colored colorant or metallic powder or printing or coating on a film.

Description

technical field [0001] The present invention relates to a bag for fruit protection, in which a light scattering member is welded in a detachable manner on the bag main body, the fruit protection bag is covered on fruits such as grapes, pears, apples, etc., and then the light scattering member is partly removed from the bag main body. It can be opened or removed by peeling off the ground, so as to protect the fruit according to the growth degree of the fruit. Background technique [0002] Conventionally, paper bags have been used to cover fruits to protect them from diseases, insects, birds, and the like. However, since the paper bag is waterproofed by coating it with paraffin wax or olefin resin, etc. so that it will not be damaged even if it is wet with water, the bag loses air permeability and is blocked from contact with the outside air. This is not only the cause of the growth of mold and miscellaneous bacteria, but also because the bag is not exposed to direct sunlight...
