Several major characteristics of PVC heat shrinkable film

Several major features of PVC heat shrinkable film Release time: 2017-03-14 At present, some domestic manufacturers have begun to develop, and the advantages of PVC heat shrinkable film are mainly manifested in the following aspects: (1) Excellent transparency: using high-grade olefin raw materials , Low haze, high transparency. In this way, the light transmittance in the morning is high and the scattering rate is low, so that the temperature rises rapidly in the morning. (2) Super continuous anti-fogging and dripping ability: Adopting anti-fogging dripping agent coating and drying treatment can inhibit the generation of fog, and the anti-fogging dripping period can be synchronized with the service life of the agricultural film. (3) Strengthen the thermal insulation performance: the film uses high-tech special organic thermal insulation agent to make most of the infrared radiation radiated from the shed is reflected back. Effectively control the heat loss. It ensures the growth temperature of crops at night and shortens the maturity period. It can effectively prevent freezing damage to crops caused by sudden temperature drops at night. (4) Long service life: The use of high-tech antioxidants and light stabilizers greatly extends the service life of the agricultural film, and can reach more than 3 years in normal use. (5) Super tensile strength: The raw material has super tensile strength and tear resistance. (6) Anti-static, non-sticky: Adopt nanotechnology, four-layer structure. Surface anti-static treatment. No precipitation, not easy to absorb dust, and achieve the effect of long-term maintenance of high light transmission. (7) Reduce pests and diseases, suitable for pollution-free vegetable production: Po film enables sufficient light in the shed, rapid temperature rise, early air release, reduced relative humidity, and pests Just light. Ultraviolet rays penetrate more and have good bactericidal performance, which can reduce the frequency of medication by more than 30%. It is very suitable for green vegetable cultivation. (8) Increasing production and income, and early market: Good light transmission performance, strong photosynthesis, high temperature, high yield naturally. It can be increased by 10-25%. The crops grow fast, generally 5-10 days in advance. (9) The crop has bright color, good taste and high quality: the ultraviolet light transmittance of ordinary film is very low, and the moderate ultraviolet light of PO film is transmitted, making the shed similar to the field planting environment. The planted crops have bright color, uniform color, good taste and superior quality. http://, PVC heat shrinkable film Previous: Main function of PVC heat shrinkable film
