Blades for HDPE, LDPE, LLDPE, PP, PE, and PA in Lung Meng extrusion machines 

Lung Meng also known as Dragon Plastic Machinery is a Taiwanese plastic converting machinery manufacturer founded in 1976.  The company prides themselves for their All In Line System, which allows blown film extruders, printers, and bag making machines to work together. Lung Meng carries a wide product range from an inch wide laboratory extruder up to six meter wide, multi-layer, 3x150 mm diameter blown film co-extruder. In addition Lung Meng has zipper profile extruder and variety of water cooling die face cutting recycling equipment. For printing Lung Meng provides a range from simple single color flexographic printing machine up to high speed, high quality, 8 color central impression printing machine.

Our general advice is that no matter how much you invest in production machines it all comes down to the blade slitting the film. If the blade cannot perform on your type of material it does not matter how advance extrusion machine you have. Lung Meng does have a very broad range of  machines for most materials. Below is an overview  of machine types, machines, materials, thicknesses, and recommended blades.
