Production methods

Jalema shapes your product idea, from concept to reality.

Jalema employs specialists in the field of plastic and cardboard processing In our factories in the Netherlands, we manufacture a variety of products especially for our customers. Increasingly, we use sustainable raw materials that are suitable for the end product’s application.

Jalema has had its own injection molding plant since 2010. In 2013, Jalema opened a new state-of-the-art, modernly equipped plant with as many as 20 injection molding machines capable of processing virtually all types of plastics (with the exception of PVC). We are increasingly working with sustainable alternatives to fossil raw materials. The machines have a capacity ranging from 60 to 550 tonnes with a volume of up to 1,800 cm3 (1,900 grams of PS). We produce in both small and large runs. A super machine park that Jalema is proud of.

Cardboard and plastic film processing

Cardboard has always been an important raw material for Jalema. Over more than 75 years, Jalema has processed around a hundred million (maybe even a billion) metres of cardboard with its machines, in various grammages and qualities. We have therefore been able to gain a great deal of experience in processing cardboard products. Besides producing folders, our machinery offers numerous possibilities for processing solid board into all kinds of shapes. Punching, gluing, folding, creasing, etc., all techniques used in the cardboard processing industry. Read more about these techniques and competencies below.

We are also experienced in processing plastic film material (especially recyclable polypropylene from 0.3 -1.5 mm). We make all kinds of customised shapes from this, in diverse models and sizes.

Sustainable raw materials

Jalema, creating sustainable business.

We are constantly looking for the latest materials for both our injection molding and cardboard activities with which we will produce in an environmentally responsible manner. These include bio-based and/or biodegradable raw materials, such as agricultural residues and nettle fibres. Currently already process “plastics” without plastic! In other words, an injection moldable material made from 100% agricultural waste that contains no plastic and thus leaves no microplastics in the environment. Do you have a specific material in mind? That’s possible. Together, we will look for the best options for developing your product. That’s possible. Together we look at the best opportunities to develop your product.

Our techniques and competencies

In our spacious factory, we have a wealth of production options. Various techniques can be used to process your product entirely according to your wishes. We distinguish between processing sheets of cardboard and recyclable plastic into end products and injection moulding. Here are some of our techniques and competencies.

Injection molding (machines)

At Jalema, both mechanical- vol electric injection molding machines are used. Due to their low energy consumption, our all-electric injection molding machines contribute significantly to the goals Jalema has set itself regarding sustainabilty. Most injection molding machines at Jalema are equipped with a robot and a long conveyor belt or box carousel. All in order to do the most efficient production with a high degree of automation.

All injection molding machines at Jalema are linked to an automatic raw material supply system which is fully routed (possibly through the drying units) through the floor to the different machine. Through this underfloor space, water and Electricity are also supplied, leaving plenty of room on the production floor for the injection molding machines and further processing of the products.

One example is our sealing machines. Jalema has extensive experience in handling products with high visual demands. Most of these products are automatically sealed right at the belt to prevent damage during transport and delivery.


Cardboard and plastic sheets are available in various sizes. To process them into a finished product, they need to be cut to size. At Jalema, we can process flat sheets up to a maximum size of 1,060 x 740 mm. The sheets can then be used to process into end products.


By punching cardboard or plastic, the sheet is given the desired form and thus prepared for further processing of the product. With our machines, we process sheets with a minimum size of 400 x 330 mm to a maximum size of 1060 x 740 mm and a thickness of minimum 0.1 mm to maximum 1.5 mm. Within these formats and thicknesses, almost all forms can be punched from a plastic or cardboard sheet.

Embossing (Pressing in relief)

Both cardboard and plastic can be embossed. This involves introducing a relief into the punch form, thereby pressing a kind of relief image/stamp into the sheet of paper or plastic. A relief stamp can be built into almost any punch.


At Jalema, there are a variety of options for printing cardboard or plastic. This way, the product can easily be personalised, both in mono and full colour.

Folding, creasing and gluing

Jalema’s machine park also includes folding machines. This way, punched sheets of cardboard can be folded and glued by machine.

In the production of various products, crease lines are used. Pre-applied crease lines make folding the material easier. Crease lines are applied inline, by means of crease lines in a die-cut (for plastic and cardboard sheets) or in a creasing cylinder or travelling creasing head (for cardboard sheets).


Special welding machines can be used to weld transparent bags onto PP sheets; this is done by means of heat. This welding can be applied up to A4 size.
