A degradable film refers to a degradable film.

Degradable film

It has the functions and characteristics of traditional plastics, and after reaching the service life, it can be split and degraded in the natural environment through the action of microorganisms in soil and water or through the action of ultraviolet rays in sunlight, and finally re-enter the ecological environment in the form of reduction. Return to nature. Domestically developed varieties have covered photodegradation, photobiodegradation, photooxidation biodegradation, high starch content biodegradation, high calcium carbonate filled photooxidation, and full biodegradation. The most commonly used are edible films and water soluble films.


Edible film

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 for inner packaging of various foods, such as wrapped candy , padding of sticky cakes, or making casings, fruit coats and capsules. It caters to the trend of fast and convenient modern consumption and has a large market in the food industry.


In recent years, countries around the world have made great progress in the research of edible film, and the application of edible film is more and more extensive. However, the edible film still has the processing property, mechanical strength and protective function compared with plastic film. Inadequacies such as poor cost and high cost.


Water soluble film

Water-soluble film refers to a film that can be dissolved in water at normal temperature. As a novel green packaging material, it is widely used in the packaging of various products in Europe, America, Japan, etc., such as pesticides, fertilizers, pigments, dyes, and cleaning. Agents, water treatment agents, mineral additives, detergents, concrete additives, chemical reagents for photography, and chemical reagents for horticultural care. The water-soluble film has been widely recognized by the developed countries in the world due to its environmental degradation characteristics such as thorough degradation, safe use and convenience. The most soluble water-soluble film is a polyethylene oxide film.


Water-soluble PVA film is a new type of green packaging material developed in recent years. It has the dual characteristics of water solubility and biodegradation. It can be completely degraded into carbon dioxide and water. It has wide application and excellent market prospect in the flexible packaging industry.
