Elmendorf tear strength

ASTM D1922, usually known as the Elmendorf tear strength (related to test originally devised for paper and board), is carried out in the machine (MD) and cross (CD) direction of the material. Measured as kN/m. Test D689-44 also applies for films. [Pg.201]

In tests of 20-mil films blown from comparable melt index pol)miers, Dow Primacor copolymers showed clearly superior Elmendorf tear strength over EVA, and up to ten times the tear strength of the ionomer. In cast films, Dow Primacor copolymers can even offer more balanced tear strength than comparable linear low material... [Pg.140]

Elmendorf tear strength values for these materials after orientation, however, are 6 and 5N/mm in MD and CD, respectively. For unoriented samples, the Elmendorf tear strengths in MD and CD are 4 and 8 N/mm, respectively [27]. The contribution of biaxial orientation in improving the mechanical properties of PLA films is therefore quite evident and this route represents an important tool for manufacturing biodegradable PLA films with good characteristics for several practical applications. [Pg.148]
