PET / PP strapping Production line(Heavy model)
|PET/PP||Φ75||9-19||2||PP100 / PET150|
PET packing strip, also known as PET plastic belt, is a world widely used new type package material substitute for steel belt. With years development on it and decrease on cost, it is now widely used in steel industry, chemical fiber industry, Aluminum industry, paper industry, Brick ceramics, Screw industry, tobacco industry, electric industry, textile industry and wood industry. It is most widely used steel belt substitute with high strength.
PET or PP straps can be produced with the same technology. It takes a few minutes to change line set-up from one to the other. Heavy duty equipment can be used for four, six and eight straps production.
