Medium Co-extrusion Blow Molding Machine – Double Station

Medium Co Extrusion - Continuous Type Blow Molding Machine
Chen Way Machinery is well-known for its 20L three-layer blow molding machines. Three-layer co extrusion blow molding machines are the most popular choice for the edible oil export countries, and their productions range from 5L to 30L jerry can.

The composition for three-layer products is usually as follows:

• The outer layer is composed of 15%-20% virgin material and masterbatches
• The inner layer is composed of 15%-20% virgin material.
• The middle layer is a combination of 60%-70% cost-effective regrind material and CaCO3 (no more than 30%) which reduces material cost by 10-12%.

By contrast, only around 5%-7% CaCO3 can be added to single-layer jerry cans, which has no evident improvement over material savings.
