Problems solved by technology

However, after this kind of bagging is put on, it still needs to spray a large amount of pesticides, which is not only laborious and time-consuming, but also causes great pollution to the environment.

Embodiment 1

[0017] Example 1: The fruit bag is made of special paper with pesticides infiltrated in the paper fiber, wherein the special paper is dry paper, the paper fiber is long, the tensile strength is 4.71mN in the longitudinal direction, 1.88mN in the transverse direction, and the burst resistance 165Kpa, sizing degree 30g / m 2 , the sun protection time is more than half a year, and the water resistance is more than 200%; the pesticide sprayed in the special paper is: lime sulfur mixture.

[0018] Compared with imported paper samples, the tensile strength of imported dry paper is 2.63mN in the longitudinal direction and 1.57mN in the transverse direction, so the tensile strength of the fruit preservation bag obtained in this example is stronger, so the fruit preservation bag can prevent the sun for more than half a year Resistant to rain and torture, the long fibers are also relatively breathable.

[0019] The fruit-preserving bag of this embodiment is bagged after fruit thinning of...

Embodiment 2

[0020] Example 2: The fruit bag is made of special paper with pesticides infiltrated in the paper fibers, wherein the special paper is wet paper, the tensile strength is 1.85mN in the longitudinal direction and 0.60mN in the transverse direction, and the pesticides sprayed in the special paper Is: milk of lime and copper sulfate, and other indicators are the same as in Example 1.

[0021] Compared with imported paper samples, the tensile strength of imported wet paper is 1.28mN in the longitudinal direction and 0.71mN in the transverse direction, so the longitudinal tensile strength of the fruit storage bag obtained in this embodiment is stronger.

Embodiment 3

[0022] Embodiment 3: This embodiment is an example of a manufacturing method of a fruit storage bag.

[0023] The production method of the above-mentioned fruit preservation bag comprises the following steps: 1). Cooking, cleaning and bleaching the pulp, using tap water for cleaning, and the pH is neutral; 2). Cleaning and filtering the pulp into a paste, and cleaning it in a general washing pulp tank Filtration; 3). Sprinkle long-acting non-toxic or low-toxic antibacterial pesticides into the pasty pulp, soak the pulp, and stir evenly with a mixer until enough pesticides are absorbed in the pulp fibers. Antibacterial pesticides can be sulfur, sulfur suspension glue agent, sulfur suspending agent, copper sulfate, etc.; 4). Sizing the pulp obtained in the third step to the Internet, forming paper, and drying to make special paper, wherein the sizing degree is 30g / m 2 , the drying temperature range is controlled at 70°C-80°C; 5). Use the bag making machine to make the above spec...

Abstract

A fruit-protecting bag for protecting growth of fruits is made up from paper pulp through digestion, bleaching, filtering, mixing it with durable non-toxic or low-toxin antibacterial chemical, stirring, making paper, baking and making the fruit-protecting bags. Its advantages include no need of spraying agricultural chemical, and high light shielding, wind and rain resistance, hydrophobicity and air permeability.

Description

technical field [0001] The invention relates to a packaging bag for protecting fruit growth and a manufacturing method thereof. Background technique [0002] At present, pomelo, bananas, citrus and other skinned fruits are widely planted in the country. These fruits are usually sprayed with pesticides to solve the pests. This will inevitably cause the fruits to be polluted by pesticides, affected by the pests, and the appearance is also poor Ugly, restricting the export of products. At present, the West, Japan, Taiwan and other places adopt new technologies for fruit preservation. This new technology is to carry out bagging after the fruit trees are thinned, and spray pesticides on the bags to avoid the fruit from being polluted by pesticides, and can prevent the damage caused by diseases and insect pests. Damage to fruits by natural phenomena such as fruit invasion and sun exposure. However, after this type of bagging is put on, it still needs a large amount of spraying o...
