The development trend of composite tube sheet

The development trend of composite tube sheet of aluminum foil composite hose is usually made of white polyethylene plate thinner, acid copolymer, aluminum foil, polyethylene, etc. Traditional aluminum foil is very thick, and usually the inclination of the aluminum foil for 40 or 30. As technology advances, the aluminum foil is more and more thin, the board and the proportion of more and more small, from 29 in 1980. 12 to 44% now. 21%. Now the thin aluminum foil only 12, this makes the barrier layer is more close to the contents. More and more paste transparency and gel ointment was welcomed by consumers. When these products installed on the transparent composite hoses, its attractive colors and good quality to let a person love, transparent hose packaging will surely have played an important role in the icing on the cake. However, when using a transparent pipe, tube contents can easily be ultraviolet radiation degradation. But now there are a lot of uv products, can effectively solve the embarrassing phenomenon. Attaches great importance to the environmental protection use, recyclable economy, reduce the loss of the raw materials is the most practical manufacturing environmental hose, the most reasonable way. When the hose in the aluminum foil blocking layer thickness from 40 tide down to 12, can save a lot of resources; When the aluminum foil blocking layer completely eliminate, replaced by EVOH, can be completely recycled products. Cosmetics, medicine and food, the first thing to consider is the health performance, the second is the barrier properties, printing adaptability and chemical resistance. Of course, we must also consider the use of efficiency and convenience. - basic, streamlined, simple These words are used to describe the cosmetics packaging, especially the hose, is only a few years ago. With rapid change, the trend has turned to another direction.
