Quality-Relevant Testing of Our Paper Sacks

The quality and product safety of our paper sacks are our highest priority. That is why our products are tested regularly during ongoing production and as part of defined quality inspections. The basis for this is the respective customer specifications, internal quality standards, and applicable norms and requirements of the food industry.

Regular Quality Inspections

As part of our quality assurance, we inspect the following characteristics, among others:

  • Dimensions of the paper sack (width, length, bottom and valve dimensions)
  • Number and structure of paper and film layers
  • Adhesive bonds and seam strength
  • Print image and print quality
  • Valve execution and functionality
  • Material and product specifications
  • Cleanliness and hygiene-relevant requirements

Inspection Intervals

The frequency of inspections depends on the respective quality characteristic and the requirements of our customers. Inspections are carried out:

  • at the start of production (initial release),
  • at defined intervals during ongoing production,
  • during product or format changes,
  • and as part of the final inspection by quality assurance.

The inspection results are documented and evaluated to ensure consistently high product quality and process reliability.

Through continuous inspections and complete documentation, we ensure that our paper sacks meet the agreed specifications and are safe for their intended application.

Traceability and Documentation Process

Complete traceability and transparent documentation are essential components of our quality management. This ensures that all production steps can be traced and documented at any time.

Traceability Along the Entire Supply Chain

The traceability of our products is guaranteed in both directions. From the raw material used to the finished paper sack, all relevant production and material data can be traced. Likewise, tracing from the delivered product back to the raw materials used is possible at any time.

Through the unique identification of materials, production orders, and finished sacks, we create maximum transparency along the entire manufacturing process. This enables fast and reliable analysis when needed, as well as high process and product safety for our customers.

Digital Recording and Material Bookings

The recording of raw materials and materials is carried out scanner-supported directly in our inventory management system. This ensures that material movements are documented in real time and error-free assignment to the respective production orders is guaranteed.

Documentation of Quality Inspections

All quality-relevant inspections and their results are documented in our QA system. Electronic recording ensures structured, traceable, and always accessible documentation of the inspections carried out.

Audit-Proof Document Control

All work instructions, procedural instructions, and quality-relevant documents are managed in an audit-proof manner within our document control system. Through regulated approval and change processes, it is ensured at all times that only current and approved documents are used in the production process.

Transparency and Safety

The combination of complete traceability and digital data recording enables high safety and creates trust among customers and partners. This ensures that our paper sacks meet the agreed specifications and satisfy the highest requirements of the food industry.
