Classification of degradable film introduced by degradable film blower manufacturer

Degradable film not only has the functions and characteristics of traditional plastics, but also can be degraded in the natural environment by microorganisms in soil and water or ultraviolet rays in sunlight after reaching its life span, or can be re-entered into the ecological environment in the form of reduction to return to nature. Domestic research and development of varieties have covered photodegradation, photobiodegradation, photooxidation biodegradation, high starch content biodegradation, high calcium carbonate filling photooxygen degradation, total biodegradation, and so on. Among them, edible and water-soluble membranes are commonly used.

Water-soluble film

Water-soluble film is a kind of film that can dissolve in water at normal temperature. As a new 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, cleaning agents, water treatment agents, mineral additives, detergents, concrete additives, chemical reagents for photography and chemical reagents for horticultural care. Water-soluble membranes have attracted wide attention in developed countries due to their thorough degradation, safe and convenient use, among which the water-soluble membranes with good solubility are polyethylene oxide membranes.

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 the internal packaging of a variety of foods, such as candy wrapped, padding for sticky pastries, or made into sausage 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, great progress has been made in the research of edible film in the world, and the application of edible film is more and more widely. However, at present, there are still some shortcomings of edible film in terms of processability, mechanical strength, protective function than plastic film, and high cost.
