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.

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.
