EASILY OPENABLE COMPOSITE FILM AND EASILY OPENABLE CONTAINER MADE OF POLYETHYLENE

摘要

PROBLEM TO BE SOLVED: To provide an easily openable composite film with good release appearance and heat resistance and with excellent opening properties and hermetic properties and an easily openable container made of polyethylene. SOLUTION: The easily openable composite film of the present invention is a composite film in which a seal layer (a layer A) and a base material layer (a layer B) are laminated and the layer A is a layer comprising 30-75 wt.% low density polyethylene a with a melt flow rate in a range of 2-20 g/10 min, 10-40 wt.% low density polyethylene b with a melt flow rate in a range of 50-300 g/10 min and the layer B is constituted of a layer comprising a polyethylene resin. In addition, the easily openable container made of polyethylene of the present invention consists of a lid material using the layer A face of such the easily openable composite film as this as a sealant layer and a container part made of polyethylene and the layer A face of the lid material and the layer A face of the lid material is constituted to be sealed.
