The Influence of mPE and POE on the Performance of PE Film
Polyethylene film is widely used in the field of composite packaging due to its simple processing technology and good heat sealing performance.LDPE and LLDPE blends are commonly used in production to prepare PE films with different properties.This paper investigates the effects of different amounts of mPE and POE on the properties of PE films.It was found that mPE has little effect on the sealing temperature of PE film,but POE can quickly reduce the sealing temperature;mPE can significantly improve the heat sealing strength and viscosity of PE film,while POE can reduce the heat sealing strength and viscosity of the film;mPE can improve the heat sealing strength of PE film with inclusions,while POE has a negative impact on this and its usage should be limited.Meanwhile,the addition of mPE and POE can effectively improve the transmittance and haze of PE films,while in terms of mechanical properties,mPE can improve while POE can reduce.When the mPE addition amount is 25%and the POE addition amount is 10%,the comprehensive heat sealing performance,optical performance,and mechanical performance of the PE film is optimal.
