Problems solved by technology

Oxygenation of edible oil will affect the taste and flavor, or even deteriorate. Therefore, the oxygen barrier property of the existing PET bottle is poorer than that of glass bottles, metal cans and other packaging forms for the freshness of edible oil.

Embodiment 1

[0045] Add components styrene-butadiene copolymer cyclization product and cobalt salt into the color masterbatch to obtain a mixture. Before injection molding, the mass of the color masterbatch accounts for 3% of the mixture, and the mixture is mixed by a screw rod, After compression and melting, it is uniformly mixed with PET slices, and the PET preform is obtained by injection molding at 270°C, and the PET preform is blown at a set temperature of 290°C to obtain the edible oil packaging bottle 01 with the function of oxygen absorption and freshness preservation.

Embodiment 2

[0047] Add components 1,3-di and vinyl-4,6 phthalic acid, ethylene glycol, and divalent cobalt ions into the masterbatch to obtain a mixture. Before injection molding, the mass of the masterbatch accounts for the proportion of the mixture After the mixture is mixed, compressed, and melted by a screw rod, it is evenly mixed with PET slices, and the PET preform is obtained by injection molding at 290°C, and the PET preform is blown at a set temperature of 270°C to obtain an oxygen-absorbing and fresh-keeping function. Edible Oil Packaging Bottle 02.

[0048] Use the above packaging bottle 01 and packaging bottle 02 to fill the edible oil with nitrogen. Such as image 3 As shown, the oxygen volume fraction in the residual gas at the top of the bottle gradually decreases with time, and finally tends to zero. It shows that the residual gas at the top of the bottle body is absorbed by the bottle body, and the oxygen in the outside world is blocked. And through the appearance obse...

Abstract

The invention provides a preparation method of an edible oil packaging bottle with oxygen uptake and fresh-keeping functions. The preparation method is characterized by comprising the following steps: providing color master batch; adding an oxygen absorbent or a raw material for preparing the oxygen absorbent into the color master batch to obtain a mixture; uniformly mixing, compressing and melting the mixture to obtain a molten mixture; adding PET (polyethylene terephthalate) into the molten mixture, uniformly mixing, and carrying out injection molding to obtain a PET bottle blank; and carrying out blow molding on the PET bottle blank at a reset temperature to obtain the edible oil packaging bottle with the oxygen uptake and fresh-keeping functions. The method is simple and convenient for large-scale industrial popularization. Compared with the existing PET bottle with the same thickness, the PET bottle prepared by the method has lower oxygen transmission rate, can effectively prolong the shelf life of the edible oil, can effectively maintain the flavor of the product, and ensures the quality of the edible oil and other products.

Description

technical field [0001] The invention relates to the technical field of packaging, in particular to a method for preparing an edible oil packaging bottle with the function of absorbing oxygen and keeping fresh and the packaging bottle. Background technique [0002] Traditionally, edible oil is packaged in large-capacity PET bottles or glass bottles. With the gradual increase in people's demand for light weight and portability, PET bottles have become the mainstream material for edible oil packaging due to their convenience and light weight. Because the edible oil will affect the taste and flavor after the oxidation reaction, and even deteriorate, the oxygen barrier property of the existing PET bottle is poorer than the packaging forms such as glass bottles and metal cans for the preservation effect of edible oil. Therefore, there is an urgent need to solve this type of problem. Contents of the invention [0003] In view of this, the present invention provides a method for ...
