Problems solved by technology

Compared with the existing air-permeable and drainage holes processed on the film, the pore diameter and hole distance used in this patent are smaller. On the one hand, the processing equipment is expensive, which greatly increases the production cost
On the other hand, the processing is difficult and the operation is complicated. It is difficult to realize the microporous film with such a hole distance and pore size by mechanical punching, and it cannot be popularized and applied. The produced physiolog

Example Embodiment

[0024] Example 1

[0025]A fully-closed high-breathable waterproof membrane bag for fruits, a binding wire 1 or a binding tape is arranged on one side of the membrane bag, and the membrane bag 2 is made of LDPE polyolefin resin, LLDPE polyolefin resin, copolymerized PP polyolefin resin, carbonic acid Calcium or talcum powder, coupling agent, modifier and dispersant are the raw materials, which are processed by coupling, compatibilizing and dispersing, banburying, extruding and dicing, and then one-time production of polyolefin by a special plastic film bag making machine for fruit. A highly breathable cast film bag, the upper end 3 of the film bag is open, and the other ends 4 are closed. The finished product performance index of the said fruit fully enclosed highly breathable waterproof film bag is: melt flow rate≥1.3g / 10min; relative density: 1.35±0.15g / cm3; water content≤0.3%; air permeability of cast film: 1000g / 24h.m2; the tensile strength of the cast film (longitudinal...

Abstract

The present invention discloses one kind of closed permeating waterproof fruit film bag. The polyolefin film bag is prepared with LDPE polyolefin resin, LLDPE polyolefin resin or PP-polyolefin copolymer resin, calcium carbonate or talcum powder, coupler, modifier and dispersant as materials in a special plastic film bag making machine. It is provided with one tying rope in the mouth.

Description

technical field [0001] The invention relates to a protective film bag for fruit growth, in particular to a fully-enclosed highly air-permeable waterproof film bag for fruit made at one time by a special plastic film bag making machine for fruit. Background technique [0002] In the high-temperature and high-humidity areas in the south and north of my country, high-quality fruits, such as apples and golden pears, are cultivated. To make the surface smooth and free from fruit rust, the biggest problem is to solve the contradiction between "water and air". That is, the rainwater and pesticides outside the bag cannot enter the bag, and the physiological water and condensed water of the fruit in the bag must evenly leak out of the bag, otherwise the temperature and humidity inside the bag will be too high, which will affect the quality of the fruit. At present, the existing fruit bagging is divided into two kinds of materials: 1. paper material (fruit fruit paper), the fruit bagg...
