The tensile properties of PLA films depend on the tensile rate, temperature and ratio. High strain rate, low temperature and high tensile ratio contribute to strain induced crystallization.

PLA has excellent optical properties and high modulus, but its elongation at break, tear strength and breaking strength are low.

PLA has the advantages of high hardness, high tensile strength and modulus. It has the same bending resistance, high gas barrier, good fat solubility and oil resistance.

Compared with PE, PLA has good printability and can be widely used as packaging materials and bags for various products in industry and agriculture.

The performance of PLA packaging is the same as that of film. It is processed from film into bag.
