Description
Technical Field
The invention relates to the field of degradable film gloves, in particular to a degradable film glove and a production process thereof.
Background
The degradable film has the functions and the characteristics of the traditional plastic, and can be split and degraded in natural environment by the action of microorganisms in soil and water or the action of ultraviolet rays in sunlight after the service life is reached, and finally, the degradable film reenters the ecological environment in a reduced form and returns to the nature. The varieties developed at home have been proposed to cover photodegradation, photo-biodegradation, photo-oxidative biodegradation, high starch content type biodegradation, high calcium carbonate filled photo-oxidative degradation, full biodegradation, etc. Among the most commonly used are edible films and water-soluble films. Edible packaging films such as chitosan edible packaging film, corn protein packaging film, modified cellulose edible packaging film, composite edible packaging film and the like can be used for inner packaging of various foods, such as wrapping candies, liners of sticky cakes, or making into casings, fruit coats, capsules and the like. It caters to the trend of rapid and convenient modern consumption, and has a large market in the food industry. The water-soluble film is a film that is soluble in water at normal temperature and is widely used for packaging various products, such as agricultural chemicals, chemical fertilizers, pigments, dyes, cleaners, water treatment agents, mineral additives, detergents, concrete additives, photographic chemicals, and gardening chemicals. The water-soluble film has been widely paid attention to because of its environmental protection characteristics such as thorough degradation, safe and convenient use, etc.
However, disposable gloves are an indispensable consumable in production and living today, and are in great demand each year. The environmental problems caused are not neglected, and in order to solve the problem, the degradable glove is generated. The traditional degradable glove, for example, the technical scheme disclosed in the patent with the application number of CN201410001883.8 and the invention name of disposable biodegradable glove and the preparation method thereof, has lower structural strength, poorer tensile resistance and easy breakage and damage.
Disclosure of Invention
Based on the above, it is necessary to provide a process for producing a degradable film glove, which aims at the technical problems of low structural strength, poor stretching resistance and easy breakage and damage of the traditional degradable glove.
A process for producing a degradable film glove, the process comprising the steps of:
