Haydale Has Food Packaging All Zipped Up

 

Haydale, (AIM: HAYD), the global advanced materials group, has started to
supply South Korean plastics developer NeoEnpla Co., Ltd with functionalised
graphene nano-platelets (GNPs) for use in food packaging.

 

Functionalised using Haydale's patented HDPlas® technology, the GNP-enhanced
thermoplastic has been used to manufacture an initial sample range of food
storage zipper bags and biodegradable plastic bags.

 

Keeping Food Fresher for Longer

 

The graphene zipper bags have shown an increase in tensile strength of 31%
compared to non-graphene LLDPE (linear low-density polyethylene) zipper
bags¹.

 

LLDPE and LDPE (low density polyethylene) are widely used in food packaging
and are ideal for food storage due to their high resistance to moisture,
tearing and chemicals. The increased mechanical strength of the graphene
zipper bags allows light weighting of the plastic, reducing the film thickness
from 90µm to 60µm per bag.

 

Food packaging primarily acts as a barrier to moisture and gases (including
contaminants) that ordinarily lead to a reduction in the shelf-life of food.

 

The new graphene-enhanced food storage bags keep the food fresher for longer
thanks to the anti-bacterial, UV and barrier properties of functionalised
graphene, resulting in less food waste. The graphene-composites polymer bags
demonstrated their own oxygen blocking effect keeping food such as bread, cake
and rice containing carbohydrates fresher for longer compared to non-graphene
bags.

 

Plastic packaging is necessary to maintain the shelf life of fresh food items,
reducing food waste by spoilage before use. By ensuring barrier performance is
delivered in products that can be recycled or composted, there is the
potential for a more sustainable approach to the challenges often faced by
producing recyclable materials.

 

Improving Sustainability of Plastics

 

With the increasing demand to reduce single use plastics and increase
recycling rates, getting the performance characteristics demanded by the
industry is a challenge. To address this, both recyclable LLDPE and LDPE were
evaluated in addition to PBAT (Polybutylene Adipate Terephthalate), a
biodegradable polymer that is already seeing increasing demand for its
biodegradable properties.

 

The new biodegradable bags contain a blend of PLA (Polylactic Acid) and PBAT,
and enhanced with GNPs, offer increased strength without affecting the
compostability of the films.

 

Haydale believes to be at the forefront of graphene and other nanomaterials
being used in food packaging through the HiBarFilm2 project, which aims to
develop the next generation of high barrier films for food packaging using
plasma functionalisation.

 

The project, which started earlier this year, aims to redesign multilayer
films into 100% recyclable and compostable mono-material solutions for the
food industry. The funded project focusses on using HDPlas® functionalised
barrier additives including graphene, to maximise barrier performance and
improve dispersion of the additives within the chosen matrix. Key project
deliverables are intended to reduce the environmental impact of packaging
plastics and offer more sustainable barrier solutions to combat food waste.
