Chemical Industry
Techne’s electric blow molding machines enable the production of plastic containers and jerrycans for various markets, including the chemical and agrochemical sectors.
Specific materials and applications.
Applications in the chemical sector include chemical and agrochemical products designed to ensure resistance, safety, and durability.
These products can be manufactured using plastic materials such as LDPE, HMWPE, HDPE, and PP, available in both monolayer and multilayer configurations up to COEX-6. Containers for the chemical industry can be produced using Techne’s extrusion blow molding machines from the E-LINE and TK-LINE series, the latter being suitable for the production of jerrycans up to 30 liters.
Examples of chemical packaging








Why choose Blow Molding for the chemical industry?
Product preservation
Multilayer COEX configurations with barrier layers ensure maximum protection of the contents.
Chemical and mechanical resistance
HDPE Containers provide maximum resistance to aggressive chemicals and withstand impacts and pressure during transportation and storage.
High production efficiency and low costs
Ideal for large volumes, reducing time and costs compared to other hollow container manufacturing processes.
Our Blow Molding machines
Co-extrusion for chemical products.
The nylon (polyamide) barrier in COEX-4 prevents chemical substances from migrating through polyethylene (PE), thereby avoiding environmental leakage. To ensure maximum effectiveness, the barrier layer must be in direct contact with the product, ensuring protection, chemical stability, and optimal preservation of the contents’ properties.
Parison Radial Adjustment, ultra-efficient jerrycans.
The P.R.A. (Parison Radial Adjustment) system, applicable to the TK-LINE series, reduces excess plastic material, accelerates production cycles through thinner walls, and decreases deformation caused by uneven cooling. The result is lighter, more resistant, and higher-performing jerrycans, increasing market competitiveness.

Frequently Asked Questions (FAQ)
Techne machines can extrude plastics suitable for the chemical industry such as LDPE, HMWPE, HDPE, and PP, ensuring high mechanical and chemical resistance. These materials are particularly suitable for industrial plastic containers, bottles, and jerrycans for aggressive contents such as chemicals and agrochemicals.
The most suitable Techne blow molding solutions are:
- E-LINE – ideal for efficient and customizable packaging production up to 5L for chemical and agrochemical products.
- TK-LINE – dedicated to the production of jerrycans up to 30 liters, widely used in the chemical sector.
Yes. Thanks to P.R.A., a radial parison adjustment system implementable on the TK-LINE series, which optimizes material distribution, enables thinner and more uniform walls, reduces deformation, and produces lighter, stronger, and higher-performing jerrycans.
Molds with shell cooling technology are designed to maximize cooling speed and improve container quality. They are among the most widely used solutions in high-productivity industrial applications, such as chemicals jerrycans, due to their ability to reduce cycle times, increase quality, and improve production consistency.
Yes. The combination of Fast Cooling technology and a cross-flow Heat Exchanger enables much faster cooling of compressed air, reducing cycle times. This system does not require special molds.
