Wuhan Handern Edible Film
1. Except that the raw materials of cellophane and fiber plastic film come from natural raw materials, the others are all synthetic polymers. The edible film described in this section is not only made from natural materials, but also edible, that is, if food is packaged, the package can be eaten together with the package. www.handern.com Breathable membrane equipment
2 This feature is particularly important for food packaging and pharmaceutical packaging. At the same time, environmental protection requirements, packaging materials must not pollute the environment. The development of the so-called green packaging materials, people are more focused on the development and use of edible film edible film, has long been known to people, the earliest use of starch as a raw material to make starch film, China's earliest used for packaging.www.handern. com breathable membrane equipment
3 Starch film, commonly known as glutinous rice paper, has been widely used in the packaging of candy in production, and can be eaten together with candy. Starch film was first made from starch and made into a film, which is expensive and difficult to put into practical use. Later, it was studied to use starch and algae gum to make edible films for encapsulating drugs to take. Later, it was invented to add Konjac powder to starch to modify it, and gradually developed into industrial production through the matching of mechanical equipment. www.handern.com Breathable membrane equipment
4. From the 20th century to the 1980s, it was not limited to internal medicine capsules, but also used for snacks, buns, etc. It has become a packaging material with high commodity value and meeting hygienic requirements. But still limited to a small range of packaged products, the second industrially produced product of edible films is artificial casings. It is made using collagen as raw material. The raw material of protein collagen mainly comes from cowhide. The leather used in the leather industry is used. The utilization rate of dermis and raw leather is high, and its colloid content is high, which is relatively economical. Guangxi Wuzhou protein casing is a manufacturer of artificial collagen casing in my country. www.handern.com Breathable membrane equipment
5. By the 1990s, the demand for small packages, freshly cut vegetables and fruits increased. However, when these vegetables and fruits are cut, they will quickly deteriorate and even spoil. Therefore, the packaging film is required to prevent the packaged object from being exposed to the air, and to keep the food fresh and extend the shelf life. In addition, the call to prevent food packaging waste pollution, some of which are concentrated not only to keep foods a certain shelf life, but also fresh, hygienic, beautiful, degradable or edible, does not pollute the environment. New edible packaging films are actively researched at home and abroad. Most edible packaging films are still processed and modified by natural edible polymers. www.handern.com Breathable membrane equipment www.handern.com Breathable membrane equipment
