Special fruit bag for pomegranate and preparation method of fruit bag

Abstract

The invention relates to a special fruit bag for a pomegranate and a preparation method of the fruit bag. The special fruit bag is prepared from the following components in parts by weight: 70-80 parts of linear low-density polyethylene resin, 20-30 parts of low-density polyethylene resin, 5-8 parts of antibacterial masterbatch, 2-3 parts of pest control masterbatch, 15-20 parts of antifog masterbatch, 15-20 parts of calcium carbonate masterbatch, 1-2 parts of ultraviolet absorbent, 0.1-0.5 part of antiblocking agent, 1-2 parts of antistatic agent, 1 part of liquid paraffin and 1-2 parts of foaming agent. The preparation method comprises the steps of uniformly stirring and mixing all the components in parts by weight, then, pouring the mixture into a film blowing machine to prepare a film bag with the thickness of 0.02-0.03mm, and sleeving a paper bag outside the fruit bag. The fruit bag is of a double-layer structure that the paper bag is sleeved outside a polyethylene bag, so that the strength and toughness of the fruit bag are enhanced, and the defects that the surface of the paper bag is rough to scratch the surface of a fruit and the paper bag is easy to tear and difficult to bag are overcome; in addition, the polyethylene bag is modified, so that the air and moisture permeability as well as pest control, antibacterial and anti-fog performances of the fruit bag are enhanced.

Description

technical field [0001] The invention belongs to the field of fruit bags, and relates to a pomegranate fruit bag, in particular to a special fruit bag for pomegranate and a preparation method thereof. Background technique [0002] Pomegranate fruit bagging is an effective cultivation technique to improve fruit quality and reduce pesticide residues. Pomegranate fruit is prone to problems such as pests, sunburn, fruit cracking, rust spots, and hemp skin during the growth period. Bagging can significantly improve the smoothness of the fruit, making the fruit surface clean, bright in color, and full of water. At the same time, bagging can prolong the growth period of the fruit. Big, high nutrition, less pesticide residues. [0003] There are two types of existing pomegranate fruit bags, paper bags and plastic film bags. The surface of the paper bag is rough, and when it is placed on the pomegranate fruit, it rubs against the fruit, which reduces the smoothness of the fruit skin,...

[0003] There are two types of existing pomegranate fruit bags, paper bags and plastic film bags. The surface of the paper bag is rough, and when it is placed on the pomegranate fruit, it rubs against the fruit, which reduces the smoothness of the fruit skin, and the paper bag is troublesome and expensive; the traditional polyethylene film bag It does not have the anti-insect and anti-bacterial funct
