15. TOPAS® COC Improves Seal Characteristics
 Seal Strength is typically maintained or improved with low Tg COC
addition levels up to 15% in LDPE, LLDPE and plastomers.
 Hot Tack strength is increased up to 100% with the addition of 15% low Tg
COC in LDPE, LLDPE, and plastomers.
 Seal Initiation Temperature (SIT) can increase by 5 to 10oC with low Tg
COC levels of 15% depending on the base polyolefin.
 Blends using high Tg COC typically reduce sealability and can be utilized
to reduce seal bar sticking in non-seal film surfaces.

19. Summary
 As a polyolefin, TOPAS® COC has good compatibility with most polyolefins.
 Addition of relatively low levels of COC can dramatically increase the modulus of
polyolefins and the modulus enhancement is maintained up to the HDT of the
COC.
 COC addition can be used to improve the barrier of polyolefins or to “fine tune” a
target transmission.
 COC improves seal characteristics of many polyolefins.
 COC enhances thermoforming and reduces curl.
