Three-layer co-extrusion blow molding machine produces 20L&30L HDPE jerry can


Plastic pollution is called "white pollution", and polyethylene is a plastic raw material that is difficult to degrade for thousands of years. The recycling of plastics is a very important direction in the research of renewable resources and utilization in recent years.

Our two-layer or three-layer co-extrusion blow molding machine can make recycled plastics used in the production of 20L&30L HDPE products. The products produced change from traditional single-layer to double-layer or multi-layer:


Double layer: new material on the outer layer and recycled material on the inner layer; the conventional ratio is 20%/80% or 30%/70%.

Three layers: outer layer new material, middle layer return material, inner layer new material; the conventional ratio is 20%/60%/20% or 30%/40%/30%.

Our double-layer hollow blow molding machine can meet the above requirements:

Double extrusion system or three sets of extrusion system: motor, reducer, screw, barrel, frequency converter, etc.;

The internal structure of the die head is made of double or triple layers;

Formwork system: 4 tie rods for direct push and clamping;

Computer system: B&R or Techmation


Our double/three-layer co-extrusion blow molding machine can manufacture the following double-layer or three-layer bottles for customers. Such bottles can achieve the following conditions:

1. Responding to the call of the world's recycled materials to reduce "white pollution"

2. In the long run, the recycled material layer reduces the cost of the bottle and increases the competitiveness of 20L&30L HDPE jerry can in the market.
