Reports and Laboratory testing

In Unibag we take great care in performing laboratory testing for our products before their launch. In this way we guarantee the quality of our raw materials, the properties of our products, and their suitability for contributing to the cycle of the circular economy, whether by compost or recycling.
We work with renowned national and international laboratories.

Reports on plant-based reusable bags

IDIEM materials and Resistance Report

The following document contains information about tests performed according to record No. 1356898 issued by the Research Development and Innovation of Structures and Materials (IDIEM) on our plant-based corn starch reusable bags, testing the material identification of the sample and resistance under moving load, according to UEM-PP-002 “Procedure for bag testing”.
The results of the material base identification tests confirm that the submitted samples have polylactic acid (PLA) characteristics.
The results of the moving load resistance tests are successful at 20 kilos, performed in 100 test cycles.

Dictuc Materials Report

The following document contains information about tests performed according to record No. 1518413 issued by DICTUC Laboratory, on the non-woven textile type material composition of our Plant-Based Corn Starch Reusable Bags.
The results indicate the petrol-derived polymers were not observed and the polymer composition is completely based on Polylactic Acid (PLA).

Armony Composting Tests

The following document contains information related to the compostability certification of our Plant-Based Reusable Bags in the Armony Sustainable Composting plant, ratifying the successful degradation in under a 180 day period, being submitted to the composting conditions in organic waste stacks, under industrial conditions, according to the procedure manuals in ISO 9001:2015 OF THE COMPANY’S Quality certification.
This demonstrates that the bags’ manufacturing process is compatible with the composting processes carried out by Armony Sustainable.
