Tensile strength and elongation of the plastic film

 

A flexible plastic film, can be extended to shrink, and a certain tensile capacity. According to tests measured as shown in Table 13:

  Tensile strength and elongation of the plastic film

 

Plastic film tensile strength is not easy to break, elongation makes plasticity strengthened. Good film tensile strength of up to 250kg / cm², an elongation of 300%. Compared with glass, light weight, unbreakable, easy to shape with a simple, lightweight material that can support a great convenience for mulching. Therefore, it can cover a large area. However, due to oxidation, temperature changes, such as ultraviolet radiation, increases the use of time, gradually aging.
