Q: How do you dry the thin plastic films before pelletizing?

We use a specialized 'Squeezing Dryer'. Unlike centrifugal dryers which are for hard plastics, the squeezer uses high screw pressure to physically squeeze water out of the film flakes and heat them up via friction, reducing moisture to under 3%.

Q: Does the light film cause feeding issues in the extruder?

Standard extruders struggle with light film. Our solution includes a Compactor (Agglomerator) integrated with the extruder, or using the 'Squeezed Popcorn' from the Squeezing Dryer. This increases the bulk density of the material.

Q: Can this line process both woven bags and agriculture films?

Yes. The line is designed with a versatile crushing and washing system. However, agricultural films usually contain more sand, so we may adjust the screen mesh size and increase water flow in the pre-washer.

Boxin delivered a high-capacity 2000kg/h turnkey solution to Cambodia for processing post-consumer agricultural films and woven bags into high-quality PP/PE granules.

Challenge: Processing Soft Plastics

The client needs to recycle huge volumes of waste LDPE films and PP woven bags. These "soft plastics" present unique challenges compared to rigid bottles:

Moisture Retention: Thin films trap water easily, making them hard to dry efficiently for the extruder.
Feeding Difficulty: Fluffy, light plastic flakes often bridge or clog standard extruder hoppers, causing unstable output.
High Contamination: Agricultural films often contain significant soil and sand residues.

The Solution: Squeezing Technology

To handle the 2000kg/h throughput, Boxin integrated a Film Squeezing Dryer (Compactor) into the line. This key machine mechanically dewaters and semi-plasticizes the material.

Process Detail: From Waste to Pellets

The complete line includes crushing, friction washing, and floating separation tanks to remove dirt. The cleaned flakes are then processed by the Squeezing Dryer, which converts fluffy flakes into dense "popcorn" granules. These dense granules are then easily fed into the pelletizing extruder, ensuring a stable, high-output production of uniform recycled pellets.

FAQ: Film Recycling Insights

Q1: How do you dry the thin plastic films before pelletizing?

A: We use a specialized "Squeezing Dryer". Unlike centrifugal dryers which are for hard plastics, the squeezer uses high screw pressure to physically squeeze water out of the film flakes and heat them up via friction, reducing moisture to under 3% for stable extrusion.

Q2: Can this line process both woven bags and agriculture films?

A: Yes. The line is designed with a versatile crushing and washing system. However, agricultural films usually contain more sand, so we may adjust the screen mesh size and increase water flow in the pre-washer to handle the higher contamination load.

Q3: Does the light film cause feeding issues in the extruder?

A: Standard extruders struggle with light film. Our solution includes a Compactor (Agglomerator) integrated with the extruder, or using the "Squeezed Popcorn" from the Squeezing Dryer. This increases the bulk density of the material, ensuring the screw grips it effectively for high output.

Q4: What is the expected lifespan of the crusher blades?

A: Processing films with sand (like mulch film) is abrasive. We use SKD-11 or D2 high-alloy steel blades. For this Cambodia project, the blades are sharpened every 40-60 hours of operation to maintain cutting efficiency and throughput.
