With the rapid development of the packaging industry and technological innovation, the market has appeared edible packaging materials, this kind of material can not only be eaten together with food, but also can block the air, play a very good antibacterial, mildew effect, extend the shelf life of products to ensure product quality and safety.
More importantly, edible packaging materials can achieve the role of degradation, in line with the concept of low-carbon environmental protection, to a certain extent, to reduce environmental pollution problems, with broad market prospects.
These edible food packaging materials, you know?
Soybean Residue edible wrapping paper (sugar film) Bean dregs wrapping paper is mainly made of waste residue as the main raw material, characterized by the use of hot water bubbles will dissolve without tearing the packaging. According to the relevant personnel, the production method is to add fatty acid and plant protease into the bean curd residue, filter out after enzymatic treatment of this residue, and then washed and dried by warm water into dry fiber, and then add Dextrin, oligosaccharides, poly propylene glycol and other adhesives made.
In the food industry, this kind of edible paper has been used, such as candy, biscuits, powdered food and drinks in the wrapping paper.
Konjac Edible Packaging Composite Film The packaging composite film has a certain selection of osmotic effect, can be good to prevent water evaporation, effectively reduce the respiration of fruits and vegetables, reduce the loss of nutrients, and has the effect of inhibiting bacteria and mold.
This packaging composite film can be used to package fruit, such as Litchi, Longan, mangosteen, etc., basically can inhibit Peel browning and dehydration, maintain the original quality of products, extended storage period and shelf shelf life.
Insect film or protein coated wrapping paper It is understood that insect film or protein coated wrapping paper is non-toxic and easy to handle, can withstand a certain amount of water and temperature disturbance.
It is understood that the wrapping paper or the container is to dissolve the shellac or protein, and then through the special processing technology, the process of the film, or coated process coated in cardboard or paper containers made of wrapping paper or packaging containers. In addition, the paper is water-resistant and breathable, because the permeability rate is higher than other materials, its surface strength and inter-layer strength, antibacterial properties, but also can absorb ammonia and so on.
At present, protein coated wrapping paper has been used in the vacuum packaging of lees stains, can be used in conjunction with other materials, as a multi-moisture semi-finished food wrapping paper, give full play to its mold, water absorption and resistance of the advantages.
Heat-sealed wrapping paper This kind of food wrapping paper has the characteristics of heat sealing, permeability, oil resistance, good water resistance, safety, harmless and so on. According to the relevant personnel, in order to achieve heat sealing, the wrapping paper in the heat sealing resin paper coated or bonded with polyethylene, and to achieve permeability is not required to do two times to obtain its utility, such as the permeability of packaging paper packaged food, microwave heating, can not produce steam in the package will affect the taste of food flavor.
At present, this kind of wrapping paper is mainly used in food, tea bags, health care products, desiccant and other packaging, and use it to package fast food, such as hamburgers.
Water absorbing function Wrapping paper This kind of wrapping paper product obvious characteristic is the water absorption ability is strong, it can maintain this material self-weight 10 times times the water absorption, and safe, harmless. Absorbent paper and non-textile water absorption capacity and water retention has a very obvious difference, water absorbent paper occupies a clear advantage. This is mainly non-woven fabrics can only be in the raw material between the pores of the fiber to maintain moisture, and the paper not only has the above ability, and its fiber itself can absorb water, to absorb water function paper after absorbing water, it becomes very soft.
As a result of these characteristics, absorbent paper can be used as the absorption of ham, sausage and other condensation of the film (film), absorbing fresh food dripping film (sheet) and the film Packaging of sanitary materials.
Corn Protein Packaging Film According to the relevant personnel, corn protein Packaging film is mainly used in fast food boxes and other oily food packaging and coating.
The membrane is a paper and corn protein synthesis of packaging materials, can not be oil vapor permeability, put into the oil pan boiling will not change the nature. In general, sustainable packaging and green packaging has become a hot topic in China's food packaging industry. As a ' green packaging ' representative, edible packaging materials in the food packaging efficiency at the same time, will not be the traditional wrapping paper as pollution to the environment, to a large extent, to reduce the environmental bearing pressure, and some of the discarded products for processing into edible packaging materials, realize the ' treasure-waste ', improve the utilization of discarded resources,
