Abstract

The invention discloses a fruit and vegetable air-conditioning freshness protection bag and a processing method thereof. The fruit and vegetable air-conditioning freshness protection bag is composed of, by weight, 100 parts of polyethylene material, 0.8-1.0 part of polyethylene glycol, 0.6-0.8 part of glycerol monostearate, 2-4 parts of silicon dioxide, 9-12 parts of styrene-butadiene-styrene, 12-15 parts of ethylene-vinyl acetate copolymer, 1.2-1.6 parts of calcium phosphate, 1.5-2.5 parts of zeolite, 0.4-0.6 part of paraffin and 0.5-2 parts of nano ZnO2. According to the fruit and vegetable air-conditioning freshness protection bag and the processing method thereof, high density polyethylene, low density polyethylene and linear low density polyethylene are combined according to a certain proportion to be used as a base material, and materials such as polyethylene glycol are used as auxiliary materials, so that the freshness protection bag has good breathability and air control capacity; high-CO2 and low-O2 dynamic equilibrium in the bag can be maintained; besides, water vapor and ripening acceleration gas can be absorbed, the phenomenon that fruits and vegetables are decayed due to the fact that the fruits and vegetables ripen quickly or are soaked by water drops is prevented, and the storage loss of the fruits and vegetables is reduced.

Description

A kind of gas-adjusting fresh-keeping bag for fruits and working method thereof
Technical field
The present invention relates to packing bag manufacture field, be specifically related to a kind of gas-adjusting fresh-keeping bag for fruits and working method thereof.
Background technology
Fruits and vegetables are the indispensable food of the mankind.Because fruits and vegetables belong to organism alive, still breathes, have metabolic activity after plucking, therefore it fresh-keepingly just seems particularly important.The kind of preserving fruit and vegetable utilizing is a lot, polyethylene blown film is as vegetable and fruit packaging thing, widely use all over the world, but current polyethylene preservative film is waterproof, airtight, and moisture easily condenses, ripening gas cannot discharge, fruits and vegetables fast-ripenin can be caused, even rot, shorten the storage time of fruits and vegetables.Invention describes a kind of gas-adjusting fresh-keeping bag for fruits and working method thereof, it is by being combined as base material according to a certain percentage by high-density, low density, linear low density polyethylene, using polyoxyethylene glycol etc. as subsidiary material, the freshness protection package obtained has good ventilation property and gas control ability, can maintain high CO in bag 2, low O 2running balance, and can absorb steam and ripening gas, what prevent from fruits and vegetables fast-ripenin or water droplet from soaking causing rots, and reduces the loss of fruits and vegetables storage.
Summary of the invention
For the deficiencies in the prior art, the object of the present invention is to provide a kind of gas-adjusting fresh-keeping bag for fruits and working method thereof.
The technical problem that the present invention solves can realize by the following technical solutions: a kind of gas-adjusting fresh-keeping bag for fruits, is made up of following raw material: polythene material 100 parts, polyoxyethylene glycol 0.8 ~ 1.0 part, Zerol 0.6 ~ 0.8 part, silicon-dioxide 2 ~ 4 parts, styrene-butadiene-styrene 9 ~ 12 parts, ethylene-vinyl acetate copolymer 12 ~ 15 parts, 1.2 ~ 1.6 parts, calcium phosphate, 1.5 ~ 2.5 parts, zeolite, 0.4 ~ 0.6 part, paraffin and nano-ZnO 20.5 ~ 2 part.
Preferably, the weight percent proportioning of described polythene material is: LLDPE: LDPE: HDPE=5: 5: 2.
A working method for gas-adjusting fresh-keeping bag for fruits, described processes step is:
(1) in proportion LLDPE, LDPE and HDPE are mixed, add the auxiliary materials such as polyoxyethylene glycol by allocation sheet, mix further through twin-roll mixing after preliminary mixing;
(2) raw material after mixing is repeatedly pulverized through pulverizer, then by 200 mesh sieves, filter out the particle that particle diameter is 0.015mm ~ 0.076mm;
(3) particle step (2) obtained drops in the tablets press of rotating speed 30r/min, after 120 DEG C, 145 DEG C, 150 DEG C and 160 DEG CGe district temperature, become particle;
(4) particle step (3) obtained drops in the plastics extruder of rotating speed 40r/min, after 150 DEG C, 160 DEG C, 170 DEG C and 165 DEG CGe district temperature, through extruding, blowing, cooling, draw with rolling out technique that to make thickness be 0.03mm finished film, then make gas-adjusting fresh-keeping bag for fruits by design specification.
Beneficial effect is: the present invention is a kind of gas-adjusting fresh-keeping bag for fruits and working method thereof, it is by being combined as base material according to a certain percentage by high-density, low density, linear low density polyethylene, using polyoxyethylene glycol etc. as subsidiary material, the freshness protection package obtained has good ventilation property and gas control ability, can maintain high CO in bag 2, low O 2running balance, and can absorb steam and ripening gas, what prevent from fruits and vegetables fast-ripenin or water droplet from soaking causing rots, and reduces the loss of fruits and vegetables storage.
Embodiment
The following detailed description of the preferred embodiment of the present invention.
The embodiment of a kind of gas-adjusting fresh-keeping bag for fruits of the present invention and working method thereof: a kind of gas-adjusting fresh-keeping bag for fruits, is made up of following raw material: polythene material 100 parts, polyoxyethylene glycol 0.8 ~ 1.0 part, Zerol 0.6 ~ 0.8 part, silicon-dioxide 2 ~ 4 parts, styrene-butadiene-styrene 9 ~ 12 parts, ethylene-vinyl acetate copolymer 12 ~ 15 parts, 1.2 ~ 1.6 parts, calcium phosphate, 1.5 ~ 2.5 parts, zeolite, 0.4 ~ 0.6 part, paraffin and nano-ZnO 20.5 ~ 2 parts.The weight percent proportioning of described polythene material is: LLDPE: LDPE: HDPE=5: 5: 2.A working method for gas-adjusting fresh-keeping bag for fruits, described processes step is: LLDPE, LDPE and HDPE mix by (1) in proportion, add the auxiliary materials such as polyoxyethylene glycol by allocation sheet, mixes further after preliminary mixing through twin-roll mixing; (2) raw material after mixing is repeatedly pulverized through pulverizer, then by 200 mesh sieves, filter out the particle that particle diameter is 0.015mm ~ 0.076mm; (3) particle step (2) obtained drops in the tablets press of rotating speed 30r/min, after 120 DEG C, 145 DEG C, 150 DEG C and 160 DEG CGe district temperature, become particle; (4) particle step (3) obtained drops in the plastics extruder of rotating speed 40r/min, after 150 DEG C, 160 DEG C, 170 DEG C and 165 DEG CGe district temperature, through extruding, blowing, cooling, draw with rolling out technique that to make thickness be 0.03mm finished film, then make gas-adjusting fresh-keeping bag for fruits by design specification.
