HDPE
Widely used in drum and bottle production thanks to its high impact strength and chemical resistance.
- Detergent and chemical packaging
- Milk bottles
- Industrial drums
SECTORS · 02
Blow molding is used to produce hollow products, from water and soft-drink bottles to jerrycans, toys and automotive fuel tanks. Different polymer groups are preferred depending on product geometry and barrier needs.
POLYMERS USED
In blow molding, the product’s contents, barrier needs and strength requirements determine material selection.
Widely used in drum and bottle production thanks to its high impact strength and chemical resistance.
Preferred in beverage bottles thanks to its high clarity and barrier properties.
Stands out in blow molding applications that need high temperature resistance.
SELECTION CRITERIA
The right polymer should be selected according to content compatibility, wall-thickness control and final service conditions.
Gas and moisture permeability directly affect the shelf life of the product.
Resistance to impacts that may occur during transport and handling is important.
Uniform wall thickness in extrusion blow molding is critical for product strength.
Clarity is a priority criterion in applications where product visibility matters.
APPLICATION EXAMPLES
Blow molding is one of the core methods preferred for serial production of hollow and lightweight products.
When choosing a polymer for blow molding, we recommend considering the product contents, storage conditions and blow molding method (extrusion or injection blow molding) together. Contact our team for suitable products and sourcing options.
FREQUENTLY ASKED QUESTIONS
Because of its impact strength and cost efficiency, HDPE is one of the most preferred polymers in blow molding applications.
It is preferred for carbonated beverages thanks to its high clarity, light weight and gas barrier properties.
In extrusion blow molding a tube-shaped parison is formed first, while in injection blow molding a preform is produced first by injection; each is chosen for different geometry and volume needs.
Polymer type, grade properties, origin and market conditions are the main factors that affect price.
