Combi caps with PCTG and PCR-Pet screw caps Ø25mm 

Due to many years of experience and the requirements of our customers, we have decided to switch to a new material. The Tritan TX 1501HF belongs to the PCTG group and complies with FDA-guidelines. In order to process this material, the manufacturing of a new valve gate tool was necessary. Because we are always happy to take on new challenges and the construction and manufacturing of tools are our passion and speciality, it was able to achieve this goal in a record time of six weeks.

Caps out of PCR-material

We also react to the increasing demand for eco-friendly products from our customers and we constantly carry out new material tests.

We are aware that the market demand for recycling products is in a continuous process. We also want to make our contribution to sustainability.

The range of different PCR materials is extensive. Not all resins are suitable for the production of our caps.

The following materials we have already tested s. flyer

Do you already offer a PCR tube or would you like to start with one and do not have a suitable PCR cap? At RUBA you will not find only a wide selection of PCR-caps, but also a competent advice and service.

Flow lines of pearl colours by cosmetic caps

During the production of caps with pearl colours many factors have to be considered. One of them is the optic, which is an important point by high-cosmetic products. Is the aesthetic the first priority for our customer, then our standard quality QL_00 is no longer sufficient and an additional service will be offered.

Before ordering caps with pearl colours, we recommend to make a previous colour sampling.

If the customer already recognizes a visual defect on the sample, which he doesn't accept, than it is worth to talk with us about possible alternatives (material, dosage, cap, addition of additives, etc.) A short summary with the most important facts you'll find in our flyer.

We are there for you!
