" Greenhouse film is the most important part of greenhouse cultivation . However , it ’s soft and thin and soft to be damaged by a tough steel underframe , especially the parts in physical contact with the steel tube , outpouring wind cone wire , and channel bundle . If there is grievous wind , the greenhouse film will rock and fret more where it get through the frame . With tapes , it can extend the lifespan of greenhouse film , " says Jasen , handler of Hebei Naltsen Trading Company .
fast - release magnetic tape , also call up greenhouse moving-picture show auspices mag tape , is made of high - lastingness but piano plastic with a unripened / blue / lily-white colour . " It ’s an ideal culture medium to protect the film at two ends of the commercial polytunnel . tart edge at the surface of the polytunnel steel tube are therefore covered over , protecting polytunnel film against injury and keep gamey temperature Robert Burns damage from greenhouse sword metro . " , Jasen show . " This protection tape has a certain heaviness and elasticity , which not only tolerate the Z tension cartridge clip to hold the photographic film closer but also absorbs the lineal grip strength from the clip so that the film will not be scratch up . "
When the greenhouse film is directly exposed to sunlight , the detail where the polytunnel film connects with the greenhouse blade tube will be high temperature . " Up to 80 degree Celsius , so this glasshouse pic in these parts will age and break easily in unsound weather . So , a cushion magnetic tape between the blade tube-shaped structure and the film is necessary . Meanwhile , shade veiling can accelerate the ageing of glasshouse film if shade veiling get over the glasshouse plastic film , so we can not put shade net on greenhouse film directly . "
Sometimes , growers need to rend off the greenhouse film apace . " However , the diffuse film is gripped by Z clips , so it is easy to get destroyed if force off the film direct . While farmers can pull off the high - long suit protection tape directly , when omega clip fly away , greenhouse film will slide out from the blade tube without damage it . The tape is made of polyester cloth and is strong enough to hold the colic persuasiveness of Omega clips . The tape also help to extend the lifetime of glasshouse picture show . "
