Domestic green food packaging

At present, the development of domestic food packaging in a green and non-polluting direction is a major trend. The following describes several green packaging materials that are currently urgently needed by the food industry. We hope to provide domestic packaging manufacturers with new food packaging ideas.

Chitosan edible packaging film

1, Application: Candy, preserved fruit, fresh cake, moon cake preservation

2, production process

This packaging film uses shellfish extract chitosan as the main raw material, combining chitosan with lauric acid to produce a uniform edible film. The peeled fruit and fruit pieces are packaged with the packaging film, which has a good freshness preservation effect.

3, project evaluation

Chitosan is a processed product after shell crushing. Because it is natural and harmless to the environment, it has the effect of supplementing trace elements to the human body after eating. Is a new type of environmentally friendly food packaging.

4. Disadvantages: The source of raw materials is limited. It must be close to the coastal area where shellfish are abundant.

Corn protein packaging film

1. Application range: It is suitable for high fat and high permeability food packaging. The fast food industry, fried potato food, moon cake production and other food companies are widely used.

2, the production process

Corn protein packaging film is mainly used in the inner layer of fast food boxes and other foods with oil. The film is a packaging material for the synthesis of paper and corn protein. It is not penetrated by oils and fats. It is put into a pot and boiled without changing its properties.

3, project evaluation

Corn protein packaging film production of raw materials, suitable for large-scale production. At present, the packaging of fried foods (potato chips, puffed foods, flavored casseroles, dried meat, etc.) is directly packed in polyester plastic packaging. From the perspective of hygiene, the inner packaging film should be used, so the packaging material has broad prospects.

Soy protein edible packaging film

1, the scope of application:

All kinds of ready-to-eat foods can be used.

2, production process:

The soybean residue extracted from soybean meal is used for production. The source of raw materials is vast. In particular, the region rich in soybeans in the North is rich in raw materials. Since soybean residues from soybean meal are used, the price is extremely cheap. The packaging film can not only prevent oxygen from entering, but also maintain moisture, but also ensure the original taste.

3, project evaluation:

Edible packaging film is widely used in the food production industry, and most of the sweets and cakes can be used. Because the package has a preservation function and rich raw materials, it has an excellent industrial prospect.

Compound edible packaging film

1, the scope of application:

Ready-to-eat food packaging.

2, production process:

This kind of protein, fatty acid and starch composite edible packaging film combines different ratios of protein, fatty acid and starch to produce edible films with different physical properties.

3, project evaluation

Because the product can adjust the softness and hardness of the packaging film according to different foods, different types of inner packagings can be formed and there should be a huge market in the food industry.
