Embodiment Construction
[0011] The present invention is based on the study of ginger's demand characteristics on temperature, light and humidity, aiming at the present situation that there is no special mulch film for ginger, and is developed through scientific and reasonable formula by adding suitable color masterbatch. The main technical indicators of the product are: the light transmittance is 40%-85%, the green light ratio of the transmission spectrum is increased by 5%-15% compared with ordinary mulch, and the film thickness is 0.006-0.02mm.
[0012] The processing and process requirements are described in detail below in conjunction with the accompanying drawings.
[0013] First, prepare no-drip insulation masterbatch (2), the weight percentage of each component is: LLDPE powder 90%-96% (1), non-drip LA-2 1%-5% (4), heat preservation agent talcum powder 3% -6% (5). The above raw materials are fully mixed and evenly heated, kneaded, extruded, drawn, cooled and cut into pellets, which becomes th...
