Matters and attention for buying plastic films

        The agricultural plastic film from the north part is usually thin and commonly used for sweet potato and peanuts growing. Since it is thin membrane, it is sticky mud easily. It will be aging fast after under bright sunshine. Therefore, when you are choosing it, you should pay attention to the content of the soil and the degree of aging. Generally, the soil account is 30% to 40%. After being dried and cleaned, it could be granulated; but the yield will be decreased with only 40% to 50%. And the quality is also not so good, which can only produce injection. This will be a big problem.

        Though the plastic film will also exposed under the sun and will aging, its aging degree is relatively low than the ground film for its thickness. It is over one meter than the ground. So at the time of purchase, the soil aging degree and soil content should be considered carefully. The common film can reproduce after being cleaned which will achieve 70% production. That’s why the plastic film is better than the ground film.
