Embodiment 1

[0030] A production process of collagen packaging film, comprising the following steps:

[0031] (1) Cow split skin, cut into cubes (size 2cm), acidified with citric acid, the pH of the acid solution is 1.0, the acidification temperature is 18°C, acidified for 48 hours, and cleaned to remove the fibrous interstitium.

[0032] (2) The acidified leather is rolled into thin slices by a defiberizer to obtain collagen fibers.

[0033] (3) Collagen fiber and plant polysaccharide are kneaded, and the auxiliary material is plant polysaccharide, and the collagen mass obtained by kneading is cooled to 8±2°C.

[0034] (4) Collagen passes through the head of the extruder, and the collagen fibers are cross-braided into two layers through the internal rotating sleeve. After detaching from the rotating sleeve, they run compoundly at the central axis, and air is introduced in the middle to maintain the stability of the caliber. To form a tubular film, the film blowing speed is 50m / min. The ...

Embodiment 2

[0037] A production process of collagen packaging film, comprising the following steps:

[0038] (1) Cow split skin, cut into cubes (size 2cm), acidified with hydrochloric acid, the pH of the acid solution is 3.0, the acidification temperature is 15°C, acidified for 24 hours, and cleaned to remove the fibrous interstitium.

[0039] (2) The acidified leather is rolled into thin slices by a defiberizer to obtain collagen fibers.

[0040] (3) Collagen fiber and cellulose are kneaded, and the auxiliary material is cellulose, and the collagen mass obtained by kneading is cooled to 5±1°C.

[0041] (4) Collagen passes through the head of the extruder, and the collagen fibers are cross-braided into two layers through the internal rotating sleeve. After detaching from the rotating sleeve, they run compoundly at the central axis, and air is introduced in the middle to maintain the stability of the caliber. To form a tubular film, the film blowing speed is 65m / min. The tubular film is ...

Embodiment 3

[0044] A production process of collagen packaging film, comprising the following steps:

[0045] (1) Cow split skin, cut into cubes (size 2cm), acidified with lactic acid, the pH of the acid solution is 2.0, the acidification temperature is 20°C, acidified for 72 hours, and cleaned to remove the fibrous interstitium.

[0046] (2) The acidified leather is rolled into thin slices by a defiberizer to obtain collagen fibers.

[0047] (3) Collagen fibers are kneaded with glycerin, and the auxiliary material is glycerin, and the collagen mass obtained by kneading is cooled to 3±1°C.

[0048] (4) Collagen passes through the head of the extruder, and the collagen fibers are cross-braided into two layers through the internal rotating sleeve. After detaching from the rotating sleeve, they run compoundly at the central axis, and air is introduced in the middle to maintain the stability of the caliber. To form a tubular film, the film blowing speed is 100m / min. The tubular film is dragg...

Abstract

The invention relates to the technical field of collagen film production, in particular to a production process and a sealing method of a collagen packaging film. The production process comprises the following steps of (1) dicing cow split leather, acidifying and cleaning; (2) rolling into sheets by a defibrator to obtain collagen fibers; (3) mixing and kneading the collagen fibers and auxiliary materials to obtain a collagen group, and cooling; (4) enabling the collagen to pass through a machine head of an extruder, wherein the collagen group is blown into a tubular film, then the tubular film is dragged by a roller to move forwards, sequentially passes through a drying area 1, a liquid spraying area, an air ring area and a drying area 2 and then is wound on the roller, and the tubular film is obtained; and (5) placing the roller, cutting the tubular film into a layered film along the direction of a folded edge, and winding the film on the roller. The packaging film prepared by the invention solves the problem of difficulty in sealing, and the application field of the collagen packaging film is expanded; and meanwhile, the invention also provides a sealing method of the collagen packaging film, which is simple and easy to operate.

Description

technical field [0001] The invention relates to the technical field of collagen film production, in particular to a production process and sealing method of a collagen packaging film. Background technique [0002] There are many literatures about preparing collagen packaging film or collagen casing. As a packaging material, collagen film is rarely seen in the market except for the large-scale production of collagen casing. The main reason is that the collagen film is not like the PE film, and the packaging is particularly difficult to seal, almost impossible to seal. At present, rolls of collagen film can occasionally be seen abroad, used to wrap meat products, and then fixed with wire mesh. Contents of the invention [0003] The technical problem to be solved by the present invention is: to overcome the deficiencies in the prior art, to provide a production process of collagen packaging film, the design of which is scientific and reasonable, the prepared packaging film...
