Innovators in machine-made reusable bag
production through collaborations with researchers
from Kaunas University of Technology.


BAGFACTORY is involved in research & development of flexible ultrasound material thermal joining technology for automatic non-woven bag manufacturing process (PET-RPET GO)”.

In the production process, the company uses ultrasonic technologies for thermal edge joining. Technological production processes using ultrasonic technologies are constantly being improved – recently the production line has introduced an innovation developed by the company’s specialists, which has allowed optimizing the standard production process and achieving a production speed of 50 non-woven PP bags per minute.

Currently, BAGFACTORY, with the participation of researchers from the KTU Ultrasound Institute, is modeling the production process of non-woven PET material bags, and the production processes for non-woven R-PET material.

The results of the research show that that not only are there realistic preconditions for the new ultrasonic material thermal bonding technology for the automatic production process of non-woven PET / RPET material bags, but there are also identified problems and R&D activities to solve these problems. The submitted project is aimed at the automatic development of a flexible ultrasonic material thermal bonding technology for the automatic production process of non-woven PET / RPET bags. The R&D activities to solve scientific and technological problems will create a technological solution for the ultrasonic joining of non-woven PET / RPET material under the conditions of an automatic production process, which can be adapted to the production facilities of non-woven PP bags currently on the market; preconditions will also be created for the implementation of this method.


BAGFACTORY uses non-woven PP material to produce our environmentally friendly reusable bags.

Non-woven PP is a recyclable plastic material; it is breathable, reusable, washable, recyclable, strong, extremely lightweight, comfortable and soft. It is a perfect choice for companies who are looking to produce environmentally friendly eco bags as a replacement for single use plastic bags or paper bags.

Normally non-woven PP bags are made out of 100% virgin fibres.

BAGFACTORY by collaboration with the non-woven PP material producer and the researchers has been developing from 90% recycled non-woven PP material.

From January, 2021 we offer our customers from various business sectors to order bags with recycled content.

We are proud that we are able to play a role to achieve a better and greener earth through our works!
