Hm Ld Blown Film Plant

Blown films, also commonly known as tubular films, are created by extruding plastic through a tubular-shaped die and then stretched and blown with air to create a very thin-walled film. Polyethylenes such as LDPE, LLDPE and HDPE polymers are common resins that are used to create blown films.Blown films extrusion is one of many polymer manufacturing processes. This method is used to produce commodity and specialized polymer films that are typically used in packaging such as shrink, stretch, barrier films (used to protect deli meat), frozen food packaging, and shopping bags.
