According to the report of the Taiwanese media NTDTV, with the development of science and technology, the traditional agriculture 'turning toward the loess, backstreet' farming methods have changed in Taiwan. Many farmers use LED lighting instead of light to bring their crops into the interior for soilless cultivation.
The outer layer of double wall heat shrinkable casing is made of high quality polyolefin alloy and the inner layer is made of hot melt adhesive. After molding, the product is crosslinked and continuously expanded by electron accelerator irradiation.
The outer layer has the advantages of softness, low temperature shrinkage, insulation, anti-corrosion and wear resistance, while the inner layer has the advantages of low melting point, good adhesion, waterproof sealing and mechanical strain buffering.
Widely used in electronic equipment wiring waterproof, leakproof, multi-strand wire harness sealing waterproof (such as home appliance wiring harness, automotive wiring harness, etc.), wire and cable branch sealing waterproof, metal pipeline corrosion protection, wire and cable repair, water pump and submersible pump wiring waterproof and other occasions.
Double wall heat shrinkable casing is produced by double layer co-extrusion process of polyolefin halogen-free flame retardant material and hot melt adhesive.
The outer layer is polyolefin, which has the characteristics of insulation, halogen-free flame retardant and low temperature shrinkage. The inner layer of hot melt adhesive has the advantages of low melting point, good adhesion, waterproof sealing and mechanical strain buffer.

In the foam box, the seedlings of one plant planted their heads neatly. Above them is the LED lighting used to replace sunlight. This is a new type of soilless culture that is popular in Taiwan. In this environment, farmers can freely control temperature, humidity, nutrient content and water.
The picture is a plant from South Africa - ice, which has been successfully planted in LED lighting environment, priced at 400 US dollars per kilogram. After many trials, the farmers identified lighting settings suitable for the growth of different plants and cooperated with the restaurants to promote them.
Compared with traditional soil-cultivated vegetables, soilless cultivation of vegetables has higher prices, but consumer acceptance is quite good. "This type of vegetable is delicious and not too cumbersome to eat. It can be eaten," said one consumer.
Can this new cultivation method replace traditional land cultivation? Professor Zhang Lili of the Institute of Technological Innovation put forward different views. She said, “The nutrients we rely on in cultivating the ploughed vegetables are actually from the earth. There are many minerals and organic matter in the earth. It is actually difficult to synthesize them artificially.â€
