New biodegradable film developed by basque researchers
The research group BIOMAT from the UPV / EHU Polytechnic School of San Sebastian in Spain has developed an innovative film hundred percent biodegradable , compostable and heat sealable from agroindustrial byproducts .
As reported from the Universidad del País Vasco / EHU ( UPV / EHU ) study results were published in the Journal of Cleaner Production.
Also explained that vegetable proteins are abundant renewable raw materials , easily obtainable and potential agro-products properties for applications in the field of packaging for their ability to form films with good barrier properties in dry conditions.
Also, being biodegradable , offer significant advantages in terms of environmental and economic . Therefore, taking into account these characteristics , BIOMAT research group of the UPV / EHU has produced a groundbreaking film for food packaging that can replace conventional films based on non-renewable resources hundred percent biodegradable / compostable .
In this sense, underlined that this new biofilm improves the properties of the current commercial film , especially with regard to transparency and barrier properties to oxygen and ultraviolet light. Another outstanding properties of the biofilm is its excellent adhesion to different surfaces.
Biofilm developed by the BIOMAT group can be heat sealed to surfaces considered " difficult" for the packaging industry , as is the case of polyethylene terephthalate ( PET). The mechanical properties of manufactured biofilm are kept at low temperatures ( -20 ° C) , not transformed into a stiff and brittle film as with some conventional films .
The researcher of the BIOMAT Group at the UPV / EHU , Pedro Guerrero , has indicated that in recent years to reduce dependence on fossil fuel based plastics has become a target "fundamental " both legislatively and socially.
In this search for alternative materials that respect the environment, both in the manufacturing process and after their useful life , the research of this group have focused on the development of biodegradable and compostable materials through enhancement of industrial products and analysis of environmental burdens associated with a product's life cycle from raw material extraction to disposal of materials after use.
