Abstract
The invention discloses a kind of preparation methods of fresh flower packaging film, include the following steps: step 1, by 5-10 parts of cornstarch in parts by weight, 20-30 parts of PE, 5-8 parts of hydroxypropyl methyl cellulose and polyethylene wax 1-3 parts, which are added in mixing and blending machine, to be uniformly mixed, and mixture one is obtained；Step 2, mixture one is transferred in reaction kettle, 1-3 parts of citric acid in parts by weight is added, 0.5-1 parts of gluconate, 0.5-1 parts and polylactic acid 1-3 parts of chitosan, is warming up to 50-60 DEG C under vacuum conditions, stirs 50-80 minutes, obtain mixture two；Step 3,1-2 parts of antioxidant in parts by weight are added in mixture two, are uniformly mixed, and in plastic film blowing machine blown film, obtain fresh flower film for packaging.The present invention has excellent mechanical property, and gas permeability is high, is conducive to extend the vitality of fresh flower.
Description
Technical field
The present invention relates to field of plant growing technology, more particularly, to a kind of preparation method of fresh flower packaging film.
Background technique
With the continuous improvement of people's living standards, fresh flower becomes the frequent consumer goods of people's daily life.Fresh flower purchase
It is beautiful to increase afterwards, usually fresh flower is packed.The existing packaging film mechanical performance for fresh flower packaging is general, while simultaneously
Preservation is not played to fresh flower, such as ventilative, antibacterial energy performance, it is therefore desirable to a kind of dedicated membrane material of fresh flower packaging is developed,
Play preferably protection and fresh flower preservation.
Summary of the invention
In order to achieve the above object, the present invention provides a kind of preparation method of fresh flower packaging film, include the following steps:
Step 1, by 5-10 parts of cornstarch in parts by weight, 20-30 parts of PE, 5-8 parts of hydroxypropyl methyl cellulose and
1-3 parts of polyethylene wax are added in mixing and blending machine and are uniformly mixed, and obtain mixture one；
Step 2, mixture one is transferred in reaction kettle, 1-3 parts of citric acid in parts by weight, gluconate is added
0.5-1 parts, 0.5-1 parts and polylactic acid 1-3 parts of chitosan, it is warming up to 50-60 DEG C under vacuum conditions, stirs 50-80 minutes, obtains
To mixture two；Step 3,1-2 parts of antioxidant in parts by weight are added in mixture two, are uniformly mixed, and blown in plastics
Film machine blown film, obtains fresh flower film for packaging.
The beneficial effects of the present invention are: the packaging film toughness is big, there is sterilization effect, while greatly enhancing gas permeability,
Further improve properties of product.
Specific embodiment
The preferred embodiments of the present invention will be described in detail combined with specific embodiments below so that advantages of the present invention and
Feature can be easier to be readily appreciated by one skilled in the art, to make apparent specific boundary to protection scope of the present invention
It is fixed.
A kind of preparation method of fresh flower packaging film, includes the following steps:
