WE PURSUE QUALITY

Certifications, Traceability and Customer Satisfaction

In order to constantly ensure the quality required by our customers (customer specifications) for our products and to guarantee traceability and overall process monitoring, Kartonfabrik Porstendorf GmbH uses state-of-the-art computerised process control systems as well as the usual laboratory tests. Thus, the different process parameters (such as moisture, grammage, flexural rigidity, degree of sizing) are controlled, monitored and optimised.

Standardised samples are taken from every customer order and the greyboard is also tested in the laboratory to fixed specifications (international standards) with a variety of testing devices in addition to the computerised monitoring. Only products meeting all required quality criteria are released for distribution.

ISO-Certification

Kartonfabrik Porstendorf GmbH was certified to DIN EN ISO 9001 (quality management standard) as greyboard manufacturer in 2006 and was one of the first companies to be certified to DIN EN ISO 9001:2008 at the beginning of 2009.

Customer focus is of the highest priority to us and we ensure a consistently high quality level of our products, in part by living the quality management system.

The 9001 standard specifies the requirements for a globally accepted quality management system (QM system), requiring an organisation to demonstrate its ability to supply products that comply with customers’ and regulatory requirements and its efforts to continually improve customer satisfaction. This standard provides the framework for a comprehensive, documented and implemented quality management system and the eight principles of quality management:

1. Customer focus
2. Leadership responsibility
3. Engagement of people involved
4. Process-oriented approach
5. System-oriented management approach
6. Continuous improvement
7. Factual approach to decision making
8. Mutually beneficial supplier relationships

Our company received the current DIN EN ISO 9001:2015 certification in January 2018.

Guaranteed Food Safety

Kartonfabrik Porstendorf GmbH’s products are regularly tested for their suitability for foodstuffs by an accredited external laboratory. The results guarantee the risk-free use of our greyboard for our national and international food industry customers.

Furthermore, during production, we only use auxiliary materials (inks, glues) that are proven to be suitable for contact with foodstuffs by our supplier with a certificate of compliance or laboratory reports.

The DIN EN ISO 22000:2005 standard stipulates requirements for a globally accepted management system for food safety. It supplements DIN EN ISO 9001:2015 with regards to the HACCP (Hazard Analysis and Critical Control Points) concept and related requirements, as per food production laws.

BRC/IoP Certification

In order to reflect the high percentage of international customers in the food industry, we have decided to extend our management system to include the BRC standard. Certification took place in September 2014. This is a binding standard for suppliers of packaging materials to the food sector. As suppliers of packaging materials for non-direct contact with foodstuffs we were certified as low hygiene risk according to the BRC standard.

Energy and Environmental Policies

A clean result – also for our environment

The natural world of Thuringia’s Saale valley has been our home for more than 100 years and is our biggest and most important supplier.
Awareness for a natural balance and environmentally-friendly production processes has increased, especially during recent years.
Cardboard production requires a high water and energy input.
That is why optimising our production processes with regards to energy efficiency, environmental sustainability and saving resources is a matter of course to us and is laid down as company policy.
As we are conscious of our responsibility towards our environment, the cardboard production process in Porstendorf is subject to an environmental management system and has been certified for its environmental sustainability since May 2009 as well as for its energy efficiency since May 2012.
