M·VERA® A5002

Plastics for soil degradable mulch films

The plastic compound was developed specifically for the production of mulch films and can be processed on conventional blown film lines – farmers can also use their existing laying and planting machinery.

M·VERA® A5002 is certified by DIN CERTCO as Biodegradable in Soil in accordance with EN 17033:2018-03, based on the criteria set out below. Mulch films made from the bioplastic M·VERA® A5002 offer a time-saving and practical solution for agriculture: after harvest, they can be left in the field and ploughed under – without the need for laborious collection, costly disposal or soil erosion.

Furthermore, M·VERA® A5002 is suitable for applications with direct food contact in accordance with EU Regulation 10/2011 and the FDA (Food and Drug Administration, USA).

Very good tear resistance, good punchability, high elongation at break and low density ensure the film's outstanding specific properties. M·VERA^®A5002 has an opaque appearance and can be easily coloured with the specially developed AF-Eco ® black masterbatch. These properties make M·VERA® A5002 a good choice for the production of films for agricultural use.

Criteria for certification by DIN CERTCO in accordance with

Biodegradable in Soil (according to EN 17033:2018-03)

The test for certain limit values of heavy metals must first be successfully completed
The test is carried out on the ground compound at approx. 23 °C
- Biodegradation: Min. 90 % within 24 months; measurement of CO₂
Ecotoxicity test: Growth test with two plant species
Nitrification test and earthworm test

Microorganisms in the soil completely decompose the ploughed-in mulch film – leaving only CO₂, water and biomass behind.

How does biodegradation work?

Naturally occurring soil microorganisms, such as bacteria and fungi, settle on the mulch film after ploughing and use it as a food source. During this metabolic process, the film is completely broken down biologically, resulting only in CO₂, water and biomass as end products. This helps maintain soil quality and prevents the formation of harmful microplastics. M·VERA® A5002 has no toxic effects on the soil or environment, as confirmed by the ecotoxicity test carried out as part of the certification process. The actual speed of biological degradation under real field conditions depends on several factors, such as the thickness of the mulch film, water availability, soil composition, availability of nutrients and oxygen, as well as other climatic and agricultural parameters.
