What are the specifications and characteristics of agricultural plastic mulch film?

Agricultural plastic mulch film, also known as plasticulture film, is a type of thin plastic sheeting used in agriculture to cover the soil surface. Its main characteristics include: 1) High light transmission, allowing sunlight to penetrate and warm the soil; 2) Moisture retention, reducing water evaporation and conserving soil moisture; 3) Weed suppression, preventing weed growth; 4) Insect and disease control, reducing pests and diseases; 5) Soil warming, promoting earlier crop growth and maturation. The specifications vary, but common thicknesses range from 0.008 to 0.02 mm, widths from 0.5 to 2 meters, and lengths from 100 to 1000 meters. The film is usually made from polyethylene or polypropylene and can be either biodegradable or non-biodegradable. It is widely used in vegetable, fruit, and field crop production to improve yield, quality, and efficiency.
