Plastic Film Recycling Lines
Turn film scrap back into usable pellets: edge trim, start-up waste and rejected rolls go through the granulating line and return to the blown film process. E-SHION builds the SJ100–SJ150 range from 150 to 500 kg/h.
Definition
What is a plastic film recycling line?
A film recycling line collects in-plant scrap, cuts and feeds it into a granulating extruder, then cools and cuts the melt into uniform pellets. The pellets are blended back into new film production — the simplest closed loop for a bag or film plant.

Process
From scrap back to film
01
Collect & pre-cut
Edge trim and waste film are collected and reduced to a feedable size.
02
Feed & extrude
The SJ granulator melts the material through a filtered extruder screw.
03
Cool & pelletize
The melt is cooled into strands or die-cut pellets with consistent size.
04
Reuse in film
Pellets are blended back into the film line — blend ratios are confirmed with our engineers for your film recipe.

Applications
Who uses film recycling lines
01
Blown film plants
Recycling edge trim and start-up waste back into the film line.
02
Bag factories
Turning rejected rolls and bag offcuts into reusable pellets.
03
Printing & converting
Recycling printed and laminated film scrap (washing may be required).
04
Recycled-content producers
Producing pellets for garbage bags and general packaging film.

How to choose
How to choose a recycling line
01
Measure your scrap volume
Daily edge trim and waste volume decides the machine size — from 150 kg/h up to 500 kg/h.
02
Define pellet quality
Film-reuse pellets need cleaner feed and stable extrusion; confirm whether washing is required.
03
Plan the loop
Position the granulator near the film line and decide the blend ratio with our engineers.

Frequently asked
questions
Can recycled pellets be used for blown film again?
Yes — recycled pellets are commonly blended back into film for bags and general packaging. The blend ratio depends on your film recipe and final product; confirm it with our engineers.
What output do the SJ granulators provide?
From 150–200 kg/h on the SJ100 up to 450–500 kg/h on the SJ150.
Do I need a washing line?
Clean in-plant edge trim can be granulated directly. Heavily contaminated or printed film may need washing before pelletizing.
What is the power requirement?
Main motor from 30 kW (SJ100) to 90 kW (SJ150); check your site power with our engineers.
What are recycled pellets commonly used for?
Garbage bags and general packaging film are typical end products for recycled PE pellets.
