In the world of biodegradable packaging, the material traceability It is a priority today more than ever.
A recent research conducted by theUniversity of Pisa has developed two innovative analytical methodologies for accurately quantify the polyethylene (PE) content inside the biodegradable bioplastics, such as those used for the production of compostable shopping bags.
New methods for identifying PE in bioplastics
The technologies developed – DSPy‑GC/MS (double‑shot pyrolysis‑GC/MS) And EGA‑MS (evolved gas analysis‑MS) – offer reliable performance and traceable results.
Here are the key points of the study:
- Regulatory contextEuropean regulations allow a maximum PE content of 1 % by weight in bioplastics. However, until now, there have been no official methods to verify this.
- Analytical techniques:
DSPy‑GC/MS: sensitive and precise, ideal for analyses compliant with stringent regulations.
EGA‑MS: faster, useful for routine checks.
- Reliability of results: both guarantee linearity, precision and detection limits lower than the 1%.
- Applicability: perfect for quality control laboratories and regulatory checks along the supply chain sustainable packaging.
Why this research is essential for the packaging industry
- Standardization of analyses: Precise tools for measuring PE improve transparency in the supply chain compostable bioplastics.
- Protection of the supply chain and the consumer: rigorous controls discourage the use of undeclared blends and guarantee the purchase of truly compliant products.
- Sustainable development: the integration of laboratory technologies allows a efficient recovery of plastic materials.
- Environmental transparency: the consumer has the right to safe and traceable materials in accordance with European standards.
The Teamplast approach: quality, control, and circularity
At Teamplast we believe in transparency and accurate technical information.
Even if we do not produce bioplastics, we are attentive to what happens in our sector and we want to ensure traceability and recyclability even for traditional plastic materials, such as LDPE and HDPE, which we deal with on a daily basis.
Our production standards include:
- Strict control of incoming raw materials
In case of non-compliance, we intervene promptly to guarantee the quality of the final product. - Traceability along the entire supply chain
We constantly monitor the quality and origin of LDPE/HDPE flows, to ensure post-use recyclability. - Technical training for customers
We support our partners with operational best practices for a conscious and compliant circular economy environmental standards. - Investment in innovation and analytical technologies
We are closely following instruments such as DSPy‑GC/MS and EGA‑MS, which represent the future of quality control for biodegradable packaging.
