Ultrathin breathable insulated edible fungus cultivation bag and preparation method thereof

Abstract

The invention relates to the technical field of edible fungus bag cultivation and discloses an ultrathin breathable insulated edible fungus cultivation bag and a preparation method thereof. The ultrathin breathable insulated edible fungus cultivation bag comprises 70 to 80% of high-density polyethylene (HDPE), 5 to 10% of breathable masterbatch, 0.1 to 0.5% of SiO2 and the balance linear low density polyethylene (LLDPE). The ultrathin breathable insulated edible fungus cultivation bag has the thickness of 10 to 22 micrometers. The preparation method comprises the following steps of preparing raw materials according to ratios, mixing, carrying out film blowing by a film blowing machine, and carrying out ultrathin breathable insulated edible fungus cultivation bag preparation. The ultrathinbreathable insulated edible fungus cultivation bag has the advantages that 1, gas exchange needed by mycelium respiration is guaranteed and a mycelium developmental capacity is improved; 2, competitor production can be controlled effectively; 3, heat-absorption and insulation effects are improved effectively; 4, compared with the common fungus cultivation bag having thickness of 35 micrometers and weight of above 3.5 grams, the ultrathin breathable insulated edible fungus cultivation bag has thickness reduced by 13 micrometers, needs raw material quantity saved by above 1.2 grams, retains theoriginal use strength and has better use effects; and 5, a use amount of plastic used for fungus cultivation bag preparation is saved by above ten thousand tons each year and thus the ultrathin breathable insulated edible fungus cultivation bag accords with the national environmental protection policy of energy saving and emission reduction.

Description

technical field [0001] The invention relates to the technical field of edible mushroom bag cultivation, in particular to an edible fungus cultivation bag. Background technique [0002] Traditional edible fungus cultivation bags are made of ordinary polyethylene or polypropylene plastics. During use, bottom bursting, bag swelling, air leakage, non-adhesive material, poor fungus growth, and miscellaneous bacteria infection often occur during use. And so on. The reason is that ordinary fungus bags are not high in strength, tear resistance, and impact resistance can not meet the needs of loading; as we all know, the thinner the fungus bag, the better the material, the better the effect of the material, the higher the quality and output of fungus; In the fungal stage, because the ordinary fungus bag does not have the function of ventilation, the oxygen required for the growth of mycelium can only be infiltrated by the sealed cotton ball or sponge cover, resulting in slow growth...

[0002] Traditional edible fungus cultivation bags are made of ordinary polyethylene or polypropylene plastics. During use, bottom bursting, bag swelling, air leakage, non-adhesive material, poor fungus growth, and miscellaneous bacteria infection often occur during use. and other phenomena

The reason is that ordinary fungus bags are not high in strength, tear resistance, and impact resistance can not meet the needs of loading; as we all know, the thinner the fungus bag, the better the material, the better the effect of the material, the higher the quality and output of fungus; In the fungal stage, because the ordinary fungus bag does not have the function of ventilation, the oxygen required for the growth of mycelium can only be infiltrated by the sealed cotton ball or sponge cover, resulting in slow growth of mycelium and not strong, miscellaneous bacteria are easy to corrode; Ordinary bacteria bags cannot effectively shield ultraviolet rays and absorb heat, resulting in mycelium death or low temperature mycelium dormancy, resulting in a decrease in the rate of ear production
