With the rapid development of the packaging industry and technological innovations, edible packaging materials have emerged on the market. These materials can not only be eaten together with food, but also block the air, which is very effective in antibacterial and anti-mildew. Extend the shelf life of the product to ensure the quality and safety of the product. More importantly, the edible packaging material can achieve the degradation effect, conform to the low-carbon environmental protection concept, and reduce the environmental pollution problem to a certain extent, and has broad market prospects.
These edible food packaging materials Do you know?
Bean dregs edible wrapper (sugar film)
The bean dregs wrapping paper is mainly made of discarded bean dregs as the main raw material. It is characterized by melting with hot water and melting without tearing. According to relevant personnel, the method is to add fatty acid and plant to the bean curd residue. The protease is filtered to remove the enzyme-treated soy cake liquid, which is then washed by warm water to form a dry fiber, and then added with a dextrin, oligosaccharide, polypropylene glycol or the like. In the food industry, 2. Edible paper has been used, such as candy, biscuits, powdered foods and beverage wrappers.
Konjac edible packaging composite film
The packaging composite membrane has a certain selective osmosis effect, can well prevent evaporation of water, effectively reduce the respiration of fruits and vegetables, reduce the loss of nutrients, and has the effect of inhibiting pathogens and molds. The packaging composite membrane can be used Packed fruits, such as lychee, longan, mangosteen, etc., can basically inhibit browning and water loss of the peel, maintain the original quality of the product, and extend the shelf life and shelf life.
Insect film or protein coated wrapping paper
It is understood that the insect film or protein coated wrapping paper is non-toxic and easy to handle, and can withstand certain moisture and temperature interference. It is understood that the wrapping paper or container is dissolved by shellac or protein, and then processed through special processing techniques. A film produced by a process, or a wrapper or packaging container made by coating on a cardboard or paper container.
In addition, the wrapper has good water resistance and good air permeability, because the penetration rate is higher than other materials, its surface strength and interlayer strength are high, it is antibacterial, and it can absorb ammonia gas. Currently, protein coated wrapping paper It has been applied to the vacuum packaging of distiller's grains and can be used together with other materials. As a packaging paper for multi-moisture semi-finished foods, it can give full play to its advantages of mildew resistance, water absorption and water resistance.
Heat sealable wrapping paper
The food packaging paper has the characteristics of heat sealability, permeability, oil resistance, water resistance, safety, and harmlessness. According to relevant personnel, in order to achieve heat sealability, the package paper should be heat sealed resin paper. The surface is coated with polyethylene or bonded with polyethylene, and the permeability is obtained without secondary processing. Foods like this kind of transparent wrapping paper can be heated by microwave, and the package will not be used. Produces steam and affects the taste of food. Currently, this type of wrapping paper is mainly used for food, tea, health care, desiccant packaging, etc., and it is used to package fast food, like hamburgers.
Water absorption function wrapping paper
The obvious characteristic of this kind of wrapping paper is that it has strong water absorption capacity. It can maintain the water absorption of the material by 10 times its own weight, and it is safe and harmless. There is a clear difference between the water absorption capacity and the water retention capacity of the water-absorbing functional paper and the non-woven fabric. Water-absorbent paper occupies a clear advantage. This is mainly because the nonwoven fabric can only retain moisture in the pores between the raw materials, and the paper not only has the above ability, but also the fiber itself can absorb water, and the water-absorbing function paper absorbs water. Because of these characteristics, the water-absorbing functional paper can be used as a film (sheet) for condensing ham, sausage and the like, a film (sheet) for absorbing fresh food dripping, and a film packaging for sanitary materials.
Corn protein packaging film
According to relevant personnel, corn protein packaging film is mainly used for packaging and coating of fast food boxes and other oily foods. The film is a kind of packaging material synthesized from paper and corn protein, which can not be wetted by grease, put it into The boiling of the oil pot will not change the nature.
In general, sustainable packaging and green packaging have become hot topics in China's food packaging industry. As a representative of 'green packaging', edible packaging materials play a role in food packaging, while not wrapping traditional packaging paper. This pollutes the environment, greatly reducing the environmental bearing pressure, and some discarded products are processed into edible packaging materials, which realizes 'turning waste into treasure', improving the utilization rate of waste resources, and future development. Unlimited potential.
