We manufacture agricultural mulch films using new multi-layer co-extrusion technology in Sri Lanka. This enables us to process raw materials that guarantee the highest level of mechanical strength and flexibility, and compatibility with all mechanical testing standards.
The black plastic film does not allow sunlight to pass through onto the soil. Thus, photosynthesis does not take place in soil in absence of sunlight below the black film. Hence, it arrests weed growth completely. The black plastic mulch is helpful in conserving moisture and controlling weed growth. However, it may increase the soil temperature. This means that plants can be set out earlier than on bare soil, and may result in earlier maturing fruit.
Clear or Transparent Mulches
The transparent film will allow sunlight to pass through and the weeds will grow. The transparent film is quite successful as soil solarization film for disinfecting the soil in order to reduce soil borne diseases and some weeds. This application is quite successful in nursery raising by solarizing the beds before sowing seeds for nursery raising, which gives near 100% seed germination & disease free nursery.
White plastic may be of less interest to us cool-weather. The benefits of white plastic in keeping weeds at bay, retaining soil moisture, and keeping the soil cool around the roots of crops such as peas, broccoli, cabbage, and cauliflower.
