Packaging production technologies


Extrusion blow molding is most often used for the production of packaging dedicated to personal care products, cleaning products and food. The materials used are: HDPE, LDPE, PP and PCR raw materials. The extrusion blow molding process begins with melting the raw material and extruding it into a sleeve of melted raw material. The next step involves the raw material sleeve being closed in a water-cooled form. Subsequently, the air is blown into the sleeve of the raw material closed in the mold in such a way that the plastic takes the desired shape.


Thanks to blow molding, we can:

  • obtain different shapes of bottles or containers and their necks,
  • thanks to two or three layers, obtain an additional barrier or use PCR content,
  • produce bottles with a handle.

Multilayer blowing

The most demanding industries need high-quality barrier packaging. In this case, multi-layer packaging is ideal. As the name suggests, they consist of several melted layers. As a result, they do not deform so easily and effectively separate the inner layer of the bottle wall from its contents, as well as from the external environment. Currently, multi-layer COEX blow molding is most often used in the production of bottles from post-consumer recycled content, i.e. PCR.

View-Stripe Blow molding

The blow molding process with View Stripe enables the production of bottles and containers with a translucent vertical line. Thanks to this, the user has control over the amount of the product used and the remaining contents of the package.

View Stripe blow molding is most often used in the production of packaging for the automotive (oils and lubricants) or horticultural (plant protection and care products) sector. This type of packaging also works well for products that need to be diluted with water in the right proportions.

Injection molding

Injection molding is the most popular process enabling us to produce a variety of packaging and closures. It involves introducing the heated and melted plastic into the mold cavity by applying high pressure, and then cooling it. As a result, the mass hardens and obtains the appropriate shape. This technique ensures very precise and dimensionally accurate production of parts of any shape. This technology is recommended for high-volume production.


The advantages of injection molding are:

  • Production speed – cycle times for parts produced by injection technology are relatively short, which translates into high production efficiency.
  • All excess raw material can be ground and reused.
  • Achieving any shape and size for a molded package or closure.
  • During one cycle, it is possible to manufacture multiple elements simultaneously.


Thanks to this technology, we are able to economically produce high-volume batches of products by increasing the number of cavities in the injection mold.

Bi-component injection

Bi-component injection, or two-component injection, allows you to combine in one injection process:

  • the same type of material in two different colors,
  • two different types of raw material, e.g. PP and TPE,

which enables the production of closures, caps and other injection elements in two different colors or with different combinations of raw materials.


This technology allows for the combination of raw materials with different properties or materials of different colors in one form – in one production process. Thanks to this, we obtain greater functionality of products and the ability to freely design different versions of the same element.

PET Production

Injection Stretch Blow Molding (ISBM)

Injection Stretch Blow Molding (ISBM) technology is most commonly used in the production of lightweight and thin bottles or containers. A few examples of these are:

  • transparent and colored bottles for beverages,
  • packaging for cosmetic products, e.g., shower gels and shampoos,
  • bottles intended for cleaning agents, e.g., universal cleaning fluids or glass / window cleaning liquids.

This process combines two well-known formulas – injection and blow molding. The most commonly used materials are PET and R-PET.


In the first step, the package is injection molded as a preform. This enables the neck / thread of the bottle to be carefully finished so that it is rigid, and the cap or other closure can fit it perfectly.
During the second step, that is blow molding, the shape of the package is formed. You can complete this process in one step. It involves injection molding into preforms that define the shape of the neck.
Then the preforms are heated to a temperature that allows them to be blown properly. As a result of blowing the preform, we obtain a finished bottle or container.
In single-step molding, both processes are performed on one machine.
