Seal Through Contamination Performance of Metallocene Plastomers

摘要

Metallocene plastomers are well known for providing superior toughness and excellent heat sealing performance in many high performance flexible packagign films. In a great many form-fill-seal applications it is also required that sealant remain functional even when the film surface is contaminated with product. This paper presents further technical evidence of the excellent sealing perofmrance of plastomers, in particular of their performance when sealing through contaminants. Both laboratory sealing experiemnts and actual actual VFFS packaging data are described.
