Technology is introduced:
Project Description: Changchun Yinghua Institute uses the Polyethylene and starch as main raw materials to prepare low-cost blown film. The film has good mechanical properties such as stretching, tear resistance and puncture resistance. It is non-toxic and tasteless, transparent, heat sealable, water resistant and gas barrier. It is suitable for various purposes such as food packaging and pharmaceutical packaging.
Technical Indicators: tensile strength > 15MPa, elongation at break > 200%, tear strength > 60KN / m2 puncture strength > 0.5J, film thickness 10-100μm, light transmittance > 80%.
