Bioplastics in injection molding
New paths to greater sustainability
Bioplastics provide the opportunity to merge injection molding with sustainable raw materials. With years of experience in bioplastics, ENGEL offers comprehensive support to ensure efficient, safe, and sustainable processing. Leverage ENGEL's solutions and expertise to get started today.
 "Types of bioplastics for injection molding | ENGEL")
Bio-PE, Bio-PA, WPC
Materials are biobased if they are made entirely or partially from renewable biological resources. Biological resources include corn, potatoes, sugar cane starch and cellulose. The injection-molded component does not degrade naturally in the environment.
PLA, PHA, PHB
These are bioplastics that are both biobased and biodegradable. Chemical processes enable the biodegradation of bioplastics. Microorganisms present in the environment convert the bioplastic into natural substances such as water or compost. The injection-molded component degrades naturally in the environment.
PE, PET, PP
Fossil-based plastics are regular plastics made from crude oil and natural gas that do not break down. They are not bioplastics. The injection-molded component does not degrade naturally in the environment.
PBAT, PCL
Alternative plastics that are biodegradable but produced from fossil sources such as crude oil or natural gas are classified as bioplastics. The injection-molded component degrades naturally in the environment.

Do you want to learn about the benefits of using bioplastics in injection molding and how to work with them? Our experts will be happy to provide you with comprehensive know-how.
Bioplastics can be processed by all ENGEL injection molding machines. This means that you can use your own ENGEL machines to produce injection-molded components from alternative plastics. You remain flexible and avoid additional investments.
Corrosion-resistant plasticizing components are essential for processing corrosive biomaterials. They ensure the longevity and safety of the system. It is also important to comply with the process parameters specified by the material supplier, especially when it comes to the processing temperature. To make high-quality shear-sensitive alternative plastics, a specialized screw shape helps reduce shear. The result: precise processing of sensitive materials.
Our digital solution, iQ weight control, precisely regulates the injection volume based on the pressure curve in the mold. This ensures optimum part quality during injection molding, even if the viscosity of the bioplastic fluctuates.
Thin-wall packaging made from alternative plastics can be produced using sandwich injection molding. One example is coffee capsules with a biodegradable PVOH (polyvinyl alcohol) barrier. Multi-layer packaging offers perfect barriers against oxygen, moisture and humidity, thus optimally preserving the freshness of the product.

The polylactide (PLA) for the ballpoint pens is produced from renewable, fast-growing sugar cane. For every kilogram of PLA produced, around one kilogram of CO2 is released. This is only around a quarter of what is produced for the same amount of conventional plastic.
Safe and sophisticated toys can be made from alternative plastics.
Bio-based TPE protects your smartphone from breakage.
Ecological ballpoint pens or fiber pens with a lower CO2 footprint.
Alternative plastics, such as bio-PA, which are scratch-resistant, impact-resistant and abrasion-resistant, can fulfill various requirements for technical plastic parts.
Coffee capsules are preferably made from bio-based and biodegradable raw materials such as PLA.
Reusable cutlery with wood fiber content is an ideal approved alternative to cutlery made of pure plastic.
