ENHANCED TACTILE RESPONSIVE AND OPTICALLY TRANSLUCENT FILM FOR PACKAGING

摘要

A polymeric composition suitable for blown film applications comprising a) 80 to 99.5 percent by weight of a continuous polymeric phase comprising a polyolefin, and b) 0.5 to 20 percent by weight of polymeric particles having i) an average particle diameter of 0.85 to 20 μm; ii) a refractive index from 1.46 to 1.61; iii) an average particle hardness from 1.2367E+10 N/m2 to 8.4617E+10 N/m2; and iv) at least 60% polymerized acrylic monomer units, is disclosed. The polymeric composition can be used to form blown film characterized by having a thickness in the range of from 5 to 350 μm, a modulus of elasticity in the range of from 5 to 133 MPa, a melt strength in the range of from 4 to 40 cN, an elongation at break in the range of from 100 to 1000%, a 45 degree gloss in the range of from 7 to 136 and a softness measured by human panel handfeel-ranking methodology, measured by ISO 8587 Sensory analysis that is higher than a film which does not contain the polymeric composition.
