described as having a density of about 0.900 g/cm to about 0.935 g/cm . Durand teaches the
terpolymer is useful for the production of films with high mechanical strength. 38
h. The Kohyama patent
Kohyama describes copolymers of an ethylene and “one or more” C to C alpha olefins. No 39

examples of terpolymers have been provided. Kohyama teaches the polymers can be used to form various
articles including films and have good impact strength, transparency, tear strength heat resistance and low
temperature heat sealability. 40
i. The Tominari patent
Tominari describes linear copolymers of ethylene and preferably “at least one” C to C alpha- 4 12
olefin. Tominari teaches that the polymers are suitable for the formation of various articles including films41
and have excellent mechanical and optical properties, blocking resistance, heat resistance, and low
temperature heat sealability. 42
j. The Sugahara patent
Sugahara describes the production of copolymers of ethylene, C to C alpha olefin and, C to C3 4 6 12
alpha olefin. The ethylene polymers are said to be suitable for the production of films with good43
mechanical properties, impact resistance and transparency. 44
