block bottom bag machine / Square Bottom Paper Bag Making Machine

Uses: It is suitable for blowing the plastic film as high density polyethylene(HDPE),low density polye


block bottom bag machine: It is used for blowing variours plastic film of low density polyethylene(LDPE), high density polyene(HDPE) and linear low density


Blow-moldingmachine (Film) In film blowing, the plastic is first extruded from a tubular die and moves upward to a film tower with a collapsing frame, guide rolls, and pull rolls driven by a motor. Air is compressed through the center of the die and infl


Forblown film extrusion mainly amorphous to semi-crystalline polymers are used which are extremely well suited for the slow cooling and bubble forming process. The thermal forming and sizing of the melt results in different film elongation and strength v block bottom bag machine
