Plastic Film Pelletizing Machine: KCP80 PE Film Trial
Trial Run Case Study for a Barbadian Client (KCP80): How a Plastic Film Pelletizing Machine Turns PE Blown-Film and Bag Scrap into Reusable Pellets
I. Client Background: The Need for PE Film Recycling in Blown-Film and Bag-Making Operations
In blown-film extrusion and bag-making, scrap is not an exception—it is a by-product of normal running. Edge trim, start-up scrap, offcuts and rejected rolls come off the line on almost every shift, and turning that material back into usable pellets is where a plastic film pelletizing machine earns its keep.
This trial project involves a client based in Barbados that runs blown-film and bag-making lines. Its daily output generates a steady volume of LDPE (low-density polyethylene) and HDPE (high-density polyethylene) film scrap, most of it from packaging bag production. That material still carries real value, and a package film recycling line is built to recover it. Sending the scrap to landfill wastes polymer and adds disposal cost at the same time.
The client therefore wanted a recycling and pelletizing system that could turn its PE packaging film scrap into pellets suitable for its own production. The goal was to raise material utilization and lower conversion cost instead of simply disposing of the waste.
To meet those requirements, KiTech Machinery reviewed the client’s material mix and recycling objectives, then recommended the KCP80 PE film compactor pelletizing machine and arranged a practical trial run before shipment .
II. KiTech KCP80: A Compacting and Pelletizing Solution for Soft Plastic Waste
For this project, the client first reached KiTech through an intermediary in El Salvador. After analyzing material type, end application and recycling targets, KiTech proposed the KCP80 compacting and pelletizing system .
The KCP80 plastic film pelletizing machine is built for soft plastic waste. It takes in-house scrap from blown-film extrusion and bag-making, and it combines compaction with extrusion pelletizing in one sequence: the film is cut, densified, melted, plasticized and pelletized without a separate agglomeration step downstream.
Across the trial runs, KiTech tracked four things: how the system handled the packaging film, the quality of plasticizing, how well melt filtration performed, and the consistency of the finished pellets.
III. PE Film Trial Run: From Raw Material to Recycled Pellets
The trial used PE packaging film as the feedstock and followed the material from first feed through to finished pellets—the same sequence the client would watch on its own floor.
1. Compaction and Agglomeration: Conditioning the Film Feed
Inside the KCP80, the film is cut, mixed and friction-heated until it densifies into a heavier, more uniform mass. Bulk density is the real problem with film: loose scrap bridges in the feed throat and stalls the extruder, so conditioning it first keeps the line running without constant intervention.
Watching the process through the viewing window shows how the cutting, heating and conveying stages hand off to one another.
2. Melting, Plasticizing and Melt Filtration: Holding the Process Steady
The conditioned material enters the extruder, where screw geometry and barrel heating melt and homogenize it. The melt then passes through a screen changer before reaching the pelletizing head.
PE films are unforgiving here. LDPE and HDPE scrap behave differently in the melt, and thin film arrives carrying moisture, print and seal residues. Stable output therefore depends on tight temperature control, screw parameters matched to the material, and filtration that clears contamination without choking the melt. A two-stage vacuum degassing unit strips the remaining moisture and volatiles before the die, and on thin film that is what separates a plastic film pelletizing machine that runs from one that only starts.
3. Water-Ring Pelletizing: Uniform, Free-Flowing Recyclate
After filtration, the melt is forced through a die and cut at the die face into pellets that are thrown into a water ring for cooling and conveying. During the trial the unit ran continuously and produced uniform pellets without bubbles or tails.
For converters who intend to put the recyclate back into film blowing or bag making, KiTech goes a step further and tests the pellets for melting behavior and contamination level.
That hands-on check gives the client something a datasheet cannot: a direct read on how the compactor-pelletizer handles its own PE film, and a basis for deciding whether the output suits its production requirements.
IV. Value of the Trial Run: Unlocking Value from In-House PE Film Waste
For a film-blowing or bag-making operation, the point of installing recycling equipment is not compliance—it is getting more usable material out of the post-industrial scrap the plant already generates.
First, material utilization improves. Pelletizing PE film scrap closes an internal loop. A package film recycling line turns trim and rejected bags back into feedstock the plant can meter into production, instead of selling scrap cheap and buying resin back at full price.
Second, raw material cost comes down. Once recycled pellets meet the quality standard for a given product, the plant can set a let-down ratio and displace part of its virgin resin purchase. That substitution, not the scrap price, is where the money is.
Third, scrap handling gets simpler. A defined recycling routine replaces ad-hoc baling and storage, and runs can be scheduled around the plant’s own production rhythm rather than around a waste contractor.
Two caveats are worth stating plainly. Whether recyclate suits an existing product line depends on the material, the quality standard and the process window, so it has to be verified rather than assumed. And the value case rests on sorting discipline, process control and consistent quality testing—without those, recyclate quietly becomes a quality problem.
V. PE Film Recycling and Pelletizing Solutions for the Blown-Film and Bag-Making Industry
Turning production scrap back into pellets is a closed loop most film and bag plants can reach with the right equipment. Getting there means matching the machine to the material. Film type, contamination level, target output, end use of the pellets and site constraints all shape the specification. That is why specifying a plastic film pelletizing machine starts with the waste stream, not the price list.
KiTech Machinery builds plastic recycling and pelletizing equipment for exactly this kind of application. We size recommendations against each client’s material characteristics and output targets, and we run trials so performance is demonstrated on real feedstock rather than asserted in a brochure.
If your plant is wrestling with PE film scrap, low recyclate utilization or rising conversion cost, contact KiTech to discuss a film recycling line configured around your material and your production targets.
