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(R) 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 bags(1).
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 90um to
60um 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(R) 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.
