Heat-sealable BOPP
Heat Sealable BOPP Film is a co extruded functional biaxially oriented polypropylene film with one side heat seal layer. It retains high transparency, good moisture barrier and excellent printability of standard BOPP, while realizing direct heat sealing performance. Suitable for gravure, flexo printing, dry lamination and high speed vertical & horizontal packaging machines. Widely used for pillow packaging, flow wrap, composite inner layer packaging for food, confectionery and daily chemical products.
