Do you know what a degradable film is?
Degradable film not only has the function and characteristics of traditional plastics, but also can be reused in the natural environment through microbial action in soil and water or ultraviolet radiation in sunlight after reaching the service life. Finally, it can be reunited into the ecological environment and returned to nature in the way of restoration. Domestic research and development of varieties have covered photodegradation, photobiodegradation, photooxidation biodegradation, high starch content biodegradation, high calcium carbonate filled photooxidation degradation, total biodegradation and so on. The most commonly used are edible and water-soluble films.
Edible packaging film, such as Chitosan Edible Packaging film, corn protein packaging film, modified cellulose edible packaging film and composite edible packaging film, can be used in the inner packaging of various foods, such as candy wrapped, sticky pastry pads, or made into intestinal coats, fruit coats and capsules. It caters to the fast and convenient trend of modern consumption and has a large market in the food industry.
In recent years, the world has made a great pause in the study of edible film, and the application of edible film is becoming more and more common. However, there are still some shortcomings of edible film in terms of processability, mechanical strength and maintenance function, which are worse than plastic film and higher cost.
Water-soluble film is a kind of film that can dissolve in water at room temperature. As a novel green packaging material, it is widely used in the packaging of various products in Europe, America, Japan and other countries, such as pesticides, fertilizers, pigments, dyes, detergents, water disposal agents, mineral additives, detergents, concrete additives, photographic chemical reagents and horticultural care chemical reagents. Water-soluble film has attracted worldwide attention due to its environmental protection characteristics such as thorough degradation, safe and convenient use, among which the most soluble water-soluble film is polyethylene oxide film.
Anhui Kangduoheng Bio-environmental Protection Technology Co., Ltd. consumes biodegradable materials, all-biodegradable materials, degradable plastic bags, degradable residue bags, disposable degradable knife and fork spoons, degradable film, rapid degradation in the soil and natural environment, non-toxic, non-polluting, non-peculiar smell, degradation will not damage the soil structure, truly achieve "from nature, but also from nature", is plastic. A good substitute for paper and material packaging.
