Abstract
The polyethylene resin 100 portions, linear polyethylene resin 200 portions, ethylene-vinyl acetate resin 20 portions. 1076 antioxidant 0.5 portions, antifogging mother granules 5 portions, 20% antibacterial mother granules 4 portions, 30% calcium carbonate mother granules 5 portions and 10% TiO2 nano material mothe granules 1 portion are mixed and blow-moulded into the nivented freshness-keeping film. Said film possesses O2 and CO2 bidirectional regulation capability, when it is used for making small package and storage, it can autoamtically regulate gas, has good antifogging and wet permeability, its bag interior does not dew, and possesses strong adsorption action for O2, CO2, aqueous vapour and ethylene gas.
Description
The invention belongs to the agricultural products fresh-keeping film, particularly a kind of freshness-retaining film added with nano material and making method.
General its fresh keeping property of preservative film can't be accomplished perfection at present.Also do not dose at present the preservative film and the making method of nano material.
The purpose of this invention is to provide a kind of freshness-retaining film added with nano material and making method, overcome the shortcoming and defect that has general preservative film technology now.Make it use fresh-keeping effect to improve.
The object of the present invention is achieved like this:
A kind of freshness-retaining film added with nano material is characterized by: by weight, its composition is:
100 parts of polyvinyl resins
0～50 part of linear polyethylene resin
10～25 parts of ethylene-vinyl acetate resins
0.3～0.6 part in 1076 oxidation inhibitor
4～7 parts of 10% antifog master batches
3～4 parts of 20% antibacterial matrices
0～15 part of 30% lime carbonate master batch
10%TiO
2The nano material master batch claims batching for 0.5～1 part according to the above ratio, behind plastic pellet mixing machine mixing, and the film that adopts single screw rod extrusion blow molding machine to be blow molded into.
Freshness-retaining film added with nano material, by weight, optimum formula is:
100 parts of polyvinyl resins
20 parts of linear polyethylene resins
20 parts of ethylene-vinyl acetate resins
0.5 part in 1076 oxidation inhibitor
5 parts of 10% antifog master batches
4 parts of 20% antibacterial matrices
5 parts of 30% lime carbonate master batches
10%TiO
2The nano material master batch claims batching for 1 part according to the above ratio, behind plastic pellet mixing machine mixing, and the film that adopts the single screw rod extrusion blow molding machine of Φ 45～Φ 65mm to be blow molded into.The making method of freshness-retaining film added with nano material is:
Master batch is made, and adopts the mixing extruding pelletization unit of high speed twin screw exhaust to finish manufacture craft:
Two, film forming adopts the single screw rod extrusion blow molding machine of Φ 45～Φ 65mm to finish.Blow molding process:
Film product
Advantage of the present invention is:
(1) has O
2And CO
2The two-ways regulation ability is carried out small packages when storage, can utilize the spontaneous controlled-atmosphere principle, adjustments of gas index effectively, and the optimum regime that makes it to keep relative stability reaches the result and the purpose of storage in controlled atmosphere.
(2) antifog preferably and water vapour permeability are arranged, though temperature fluctuation was arranged in storage period, (bag in) be dewfall not substantially.
(3) to O
2, CO
2, water vapour, ethylene gas etc. have the stronger adsorption and the ability of seeing through.
(4) film performance and Stability Analysis of Structures can anti-oxidant and anti-aging.
(5) transparency, pull resistance, flexibility, opening are good.
Fresh-keeping effect:
Freshness-retaining film added with nano material is to the influence of fresh keeping time (room temperature 20 ℃ under deposit)
Fresh keeping time/sky film kind cauliflower green pepper garlic stems caraway peach does not have packing 1331 2LDPE 36 12 5 5LDPE/EVA 6 10 21 7 9LDPE/EVA calcium carbonate 8 13 25 9 12LDPE/EVA carbonic acid 9 15 32 10 14 calcium, nano material
Add of the influence of nano material preservative film to the fruits and vegetables rate of weight loss
Fruits and vegetables weight-loss ratio % film kind cauliflower green pepper garlic stems caraway peach does not have packing 13.2 18.4 15.6 15.1 13.6LDPE 8.1 6.6 8.8 8.0 3.8LDPE/EVA 6.2 5.2 8.2 7.3 2.0LDPE/EVA calcium carbonate 2.3 3.9 6.7 5.6 1.6LDPE/EVA carbonic acid 1.3 3.2 5.6 5.2 1.4 calcium, nano material
Presentation of results, adding nano material in the preservative film all has certain regulating effect to the respiratory intensity of ventilation property, water vapour permeability and the fruits and vegetables of film, if cooperate condition such as low temperature again, the fresh-keeping effect of fruits and vegetables will have bigger raising.
