Abstract

The invention discloses a preparation method for a fruit and vegetable modified atmosphere packaging film. The film consists of the following components in parts by weight: 100 parts of polyethylene resin, 20-24 parts of poly-4-methyl-1-amylene, 30-34 parts of polyvinyl acetate, 4-6 parts of zinc stearate, 3-5 parts of calcium stearate, 5-7 parts of heavy calcium carbonate, 4-6 parts of diatomite powder, 3-5 parts of activated carbon powder, 6-8 parts of isopropyl dimethacrylate, 1.5-2.5 parts of 3,5-di-tert-butyl-4-hydroxy phenylpropionic octadecyl ester and 2-4 parts of liquid paraffin. The preparation method comprises the following steps: sufficiently blending the materials for 25-45 minutes by using a high-speed mixer at the rotating speed of 270-300 r/m; then carrying out film blowing on the blended materials by using a film blowing machine to prepare a fruit and vegetable antibacterial fresh-keeping packaging material, wherein the film blowing temperature is 190-200 DEG C, and the rotating speed is 16-20 r/m.

Description

A kind of preparation method of fruit and vegetable air-conditioning packaging film
Technical field
The present invention relates to field of packaging material, relate in particular to a kind of preparation method of fruit and vegetable air-conditioning packaging film.
Background technology
Fruits and vegetables spontaneous controlled-atmosphere preservation is to adopt the film packaging with certain air permeability to adopt rear fruits and vegetables, relies on the metabolism of fruits and vegetables self, reduces the oxygen concentration in packing bag, and maintains bag interior certain gas concentration lwevel and humidity, thereby prolong storage period.The preservative film generally using is at present polyethylene and polyvinyl chloride film, and they have positive effect to the controlled atmosphere of most fruits and vegetables.But the physiological property difference of every kind of postharvest fruit and vegetable.For respiratory intensity high or the fruits and vegetables that easily produce carbonic acid gas injury, as banana, date, pears, Fuji apple, pimento etc., preservative film used should have higher ventilation property, to reduce gas concentration lwevel or increase bag internal oxygen gas concentration in bag, to the relatively high fruits and vegetables of metabolic speed, as banana, tomato etc., film used should have good ethene transmitance or have the absorption decomposition function of ethene.But the polyethylene and the polyvinyl chloride preservative film that generally use at present all do not reach these requirements, and the method for generally taking to place ethylene absorbent for the higher fruits and vegetables of acetate releasing quantity in common freshness protection package, has increased operation, labor force and cost.
Summary of the invention
The object of the invention is to propose a kind of preparation method of fruit and vegetable air-conditioning packaging film, the method, by the adjustment to film composition, overcomes the defect of prior art, increases the ventilation property of film, reduce the content of the ethene in atmosphere surrounding in bag, extend the fresh keeping time of fruits and vegetables.
For reaching this object, the present invention by the following technical solutions:
A preparation method for fruit and vegetable air-conditioning packaging film, this film is made up of following component in weight part: 100 parts of polyvinyl resins, poly(4-methyl-1-pentene) 20-24 part, Vinyl Acetate Copolymer 30-34 part, Zinic stearas 4-6 part, calcium stearate 3-5 part, water-ground limestone part 5-7 part, diatomite in powder 4-6 part, activity charcoal powder 3-5 part, sec.-propyl dimethacrylate 6-8 part, 3,5-di-t-butyl-4-hydroxy phenylpropionic acid octadecyl ester 1.5-2.5 part, whiteruss 2-4 part; Described preparation method is: use high-speed mixer that above-mentioned material is fully mixed, mixing time 25-45 minute, rotating speed 270-300 rev/min; Use inflation film manufacturing machine to carry out blown film to the material after mixing and make fruits and vegetables antibacterial fresh-keeping packaging material, blown film temperature 190-200 ℃, rotating speed is 16-20 rev/min.
Beneficial effect of the present invention is:
The present invention adds the higher poly(4-methyl-1-pentene) of appropriate ventilation property and regulates controlled atmosphere performance in matrix resin polyethylene, adds appropriate water-ground limestone to improve mechanical property and the permeability of film, guarantees high carbon dioxide and the OTR oxygen transmission rate of packaging film.The diatomite that interpolation absorption property is good and gac are as absorption additive, and two kinds of raw material sources are extensive, and cost is low, and advantages of good adsorption effect realizes the reduction of ethylene content in atmosphere surrounding in bag.Comprehensively improve the controlled atmosphere of packaging film with this, extend the object of preserving fruit and vegetable utilizing time.
