This video provides you with a comprehensive analysis of the working principle, technical advantages and application scenarios of the double-layer IBC blow molding machine. Double-layer co-extrusion blow molding technology is the current mainstream process for IBC ton barrel production. Through the combination of new HDPE in the inner layer and anti-UV/recycled materials in the outer layer, it can significantly reduce production costs while ensuring food safety. Whether you are a practitioner in the chemical packaging industry, a factory investor, or an engineer interested in blow molding technology, this video will bring you practical value.

"IBC stands for Intermediate Bulk Container, a medium-sized bulk container widely used for liquid storage and transportation in industries such as chemicals, food, and pharmaceuticals. A double-walled IBC blow molding machine is a specialized piece of equipment used to produce the inner liner of 1000L to 2000L double-walled IBC containers."
"It uses high-molecular-weight, high-density polyethylene—HDPE—as the main raw material. Unlike single-walled equipment, the double-walled blow molding machine uses two extruders and a co-extrusion die to simultaneously extrude two different formulations of materials, forming a double-walled preform, which is then blow-blown into shape."
"Why double-LAYER?"
"The typical characteristics of double-walled IBC containers..." The structure is as follows: the inner layer uses 100% new food-grade HDPE, ensuring the surface in contact with the contents is pure, safe, and corrosion-resistant; the outer layer can use UV-resistant materials or recycled materials, providing outdoor durability and cost advantages.
"The advantages of this design are very obvious:"
First, improved outdoor durability—the UV-resistant outer layer prevents the container from aging and cracking under direct sunlight;
Second, reduced material costs—the outer layer can use processed recycled HDPE, significantly reducing material costs;
Third, extended product lifespan—the double-layer structure provides better long-term stability and mechanical strength.
"For this reason, double-walled IBC containers have become the mainstream choice in the European and Asian markets.
The IBCs produced by double-walled IBC blow molding machines have a wide range of applications:
Chemical Industry: Storage and transportation of various chemical solvents, lubricants, and additives
Food Industry: Packaging of liquid foods such as edible oils, juices, syrups, and dairy products
Pharmaceutical Industry: Storage and transportation of raw materials and intermediates that meet food-grade standards
Export Trade: Long-term outdoor storage and ocean shipping scenarios
