Abstract: A peelable seal comprises a mixture of at least two immiscible polymers. The first polymer forms a continuous phase in the peelable seal, whereas the second polymer is dispersed in the continuous phase. For example, a peelable seal can also be made from a mixture of an ethylene polymer with a melt index in the range from about 0.1 to about 20 g/10 minutes and a propylene polymer with a melt flow rate in the range from about 0.01 to about 2 g/10 minutes. The two polymers define a shear viscosity differential: nullnullnull(null1nullnull2)/null1null, wherein null1 and null2 are the respective shear viscosity for the first and second polymers at a temperature of 230null C. and a shear rate of about 100 radian/second. Preferably, the shear viscosity differential is less than about 100%.

Abstract: A method for producing a nonwoven fabric comprises passing a fiber web through a pair of rollers to obtain a thermally bonded fabric with a high percentage of bond areas. The high percentage of bond areas is formed by an engraved pattern on at least one of the rollers. The engraved pattern has a high percentage of bond point areas and wide bond point angles. The nonwoven fabric has increased tensile strength, elongation, abrasion resistance, flexural rigidity, and/or softness.
