PLASTIC PACKAGING
Injection moulding.
Step by step.
In injection moulding, plastic granulate is heated until it melts. The liquid mass is then pressed into a precise mould under high pressure. Once the material cools, it hardens. The mould opens, the part falls out – done.
Sounds simple? It's not. To ensure that everything fits perfectly, temperature, pressure and cooling time must be perfectly coordinated. This is the only way to produce components that are not only stable but also dimensionally accurate and of consistent quality. And best of all, the entire process runs every second.
The big advantage: almost any shape and size can be produced – from classic cases to unusual special solutions. And all with very little material waste.
Individually crafted in the Black Forest
Injection moulding - made in Germany
High quality and affordable - at LESER, these two things go hand in hand. Our fully automated injection moulding takes place right here on our premises in the Black Forest. This saves on transport, time and costs - and often makes our products more affordable than imports from the Far East.
4 reasons why LESER plastic packaging stands out:
- Production in Germany: Everything is handled in-house - short lines of communication, direct contact, and full control.
- Consistent quality: Whether 100 or 100,000 units - every LESER package meets the same standards.
- A wide range of products: Coin capsules, coin cases, plastic boxes, cases - we manufacture whatever you need.
- Complete flexibility: design, colour, process - you’re in control, we deliver the result.
Just as you wish
Standard is a thing of the past. With our extensive range of tools, LESER offers you a wide selection of shapes, sizes, Series and colours - perfectly suited to jewellery, watches, coins, medals & decorations.
Do you want your packaging to be truly unique? No problem. For orders above a minimum quantity, we can produce it in your chosen colour. This transforms functional LESER packaging into a true brand ambassador - as distinctive as your brand itself.
Customer reference: Fink Orfebres
We have developed a bespoke packaging solution for our client Fink Orfebres, a renowned manufacturer of high-quality jewellery: a white plastic box made from 100% cornstarch, featuring an elegant logo print and an integrated QR code on the lid.
The clear design language and the elegant look of the box emphasise the premium character of the brand and at the same time create practical added value - the QR code combines the physical product with digital content.
Plastic packaging made from recycled plastic
Plastic can be recycled - at LESER, we make full use of this opportunity.
3 specific examples from our production:
- 100% recycled plastic - The 1700 FUTURA series is made from 100% recycled plastic. On request, we can also develop bespoke solutions made from rPET for your brand.
- Reducing scrap in injection moulding - Our injection moulding process is optimised to minimise scrap. Sprues and defective parts are shredded in-house and directly reused as material for new products (usually as subsequent batches in different colours).
- Material recycling within our own production facilities - we do not dispose of production waste, but instead return it to the next production stage as a raw material. This ensures that the plastic used remains within the material cycle for as long as possible.

Frequently asked
questions
Bio-based plastics are made entirely or partly from renewable raw materials - such as maize starch, sugar cane, wood fibres or vegetable oils. The main difference compared to conventional plastics lies in the raw material base: instead of fossil-based raw materials such as crude oil, renewable plant-based raw materials are used as the starting material.
Important clarification: ‘Bio-based’ and ‘biodegradable’ are two distinct properties that do not necessarily go hand in hand. A bio-based plastic is not necessarily biodegradable - and vice versa.
Our material in the 1560 EARTH series: The main raw material used in the plastic is derived 100% from maize starch (a renewable resource). Under the specific conditions of industrial composting facilities (controlled temperature and humidity over several weeks), the material breaks down completely. It is not suitable for household organic waste or home composting. Functionally, the material is in no way inferior to conventional packaging plastics – a concrete material option for brands wishing to incorporate alternative raw material sources into their packaging range.
