preparation example Construction

[0034] refer to figure 2 , the present invention proposes a method for preparing a highly air-permeable, moisturizing and antibacterial fruit and vegetable fresh-keeping carton, comprising the following steps:

[0035] S1. Peel and remove the slag from cattail grass, mix it with wood residue and bamboo residue, and then cook it with cooking liquid to obtain material a. The cooking temperature is 150-170° C. and the time is 2-4 hours; add calcite powder, orthorhombic to material a. Zeolite powder, mordenite powder, nano-silica and nano-titanium dioxide are stirred evenly, and then continue to cook to obtain material b. The cooking temperature is 120-130°C, and the cooking time is 4-6h; then the material b is prepared, made, dried, pressed Lighting, rolling, cutting, sorting, and packaging to obtain paper materials;

[0036] S2. Blending linear low-density polyethylene and polystyrene at 90-160°C to obtain material c, adding preservatives, anti-fogging agents, antibacterial ag...

Embodiment 1

[0039] The present invention proposes a highly breathable, moisturizing and antibacterial fresh-keeping carton for fruits and vegetables, comprising a paper layer 1, an adhesive layer 2 and a fresh-keeping film 3, the adhesive layer 2 is wrapped around the outer periphery of the paper layer 1, and the fresh-keeping film 3 is wrapped around the adhesive layer 2 perimeter.

Abstract

The invention discloses a fruit and vegetable fresh keeping carton with high ventilation, moisture preservation and bacteria resistance. The invention further discloses a preparation method of the fruit and vegetable fresh keeping carton with high ventilation, moisture preservation and bacteria resistance; after scirpoides holoschoenus is mixed with wood slag and bamboo slag for stewing, calcite powder, acadizcolite powder, mordenite powder, nanometer silicon dioxide and nanometer titanium dioxide are added and uniformly stirred for stewing, mixing, papermaking, drying, polishing, paper rolling, cropping, sorting and packing to obtain a paper material; linear low-density polyethylene, polystyrene, a preservative, an antifogging agent, an antibacterial agent, white carbon black, silica gel, Dagu stones, ceramic particles and polyolefin are mixed and homogenized, are heated, shorn, extruded and pelletized by a double-screw extruder, and are blown by a single-screw film blowing machine to obtain a material e; bonding layers are uniformly coated at the periphery of the paper material; and the material e is coated at one sides, far from the paper layer, of the bonding layers. The fruit and vegetable fresh keeping carton has high ventilation and high moisture preservation, and has the antibacterial effect.

Description

technical field [0001] The invention relates to the technical field of fruit and vegetable preservation, in particular to a highly air-permeable, moisturizing and antibacterial fruit and vegetable preservation carton and a preparation method thereof. Background technique [0002] Fruit and vegetable preservation is a practical technology for conditioning and picking fruits and vegetables based on the physiological activities of fruits and vegetables. Preservation means providing a suitable storage environment for fruits and vegetables, moderately maintaining the life activities of fruits and vegetables, delaying the aging process, maintaining the freshness, aroma and appearance of fruits and vegetables, so that fruits and vegetables are not weak in off-season and not rotten in peak season. The current storage and preservation methods mainly include low-temperature refrigeration, controlled atmosphere, irradiation, chemical sterilization and plastic wrap packaging. However, ...
