Popular types of agricultural mulch films
There are many different types of agricultural mulch films (PE films). But in general, they only differ in size and thickness. The rest of the agricultural PE films are almost the same. The different sizes are to serve different growing needs. For examples, depending on the type of plant, whether the bed (bed) is large or small.
