Which Material Slitter Knife Is More Suitable For PP/PE Film Cutting?

Which material slitter knife is more suitable for PP/PE film cutting?

Which material slitter knife is more suitable for PP/PE film cutting? 9CrSi, D2, HSS or carbide? This problem is very important for many plastic film manufacturers.

PE film, that is, polyethylene film, refers to the film produced with PE particles. PE film has moisture resistance and low moisture permeability. Polyethylene film (PE) can produce low-density, medium-density, high-density polyethylene and cross-linked polyethylene and other products with different properties according to different manufacturing methods and control methods.

PP film, namely polypropylene film. PP film has the characteristics of moisture resistance, high mechanical strength, good dimensional stability, light weight, non-toxic, odorless, good printing performance, etc. Vacuum aluminum plating, capacitors, etc.

Generally, customers think that the better the material, the more suitable the blade with higher hardness. However, PE/PP films have different characteristics and properties, so the material and hardness of the suitable slitting knives are also different.

A customer reported that when he used a slitter blade to cut PE film, he encountered the phenomenon of sticking the knife edge. After the calculation and research of our engineers, it is recommended to change the blade material and increase the hardness to 64 HRC to help customers find the most suitable knife for them, which is cost-effective and super durable, and customers are very satisfied.

In short, the knife suitable for cutting the object is the best. Do you have the same question about which material slitter knife is more suitable for PP/PE film cutting? Contact us, we are always ready to help you.
