Plastics packaging for the food and beverage industries: A case study in changing attitudes 08 August Matthew Hancock History of packaging Traditionally the food and beverage packaging industry was dominated by glass. Many properties of glass make it an ideal packaging material: Glass can be shaped and coloured, and it is reusable and recyclable.
A potential opportunity to expand into a different segment, potentially to fast food, requires a quick roll- out of new Pronto concept to establish it as a powerful brand (pg.1). However, quick expansion plans would require adopting franchising or syndication models of ownership (pg.1). Case Study: Molded Plastics Plant Saves Over $K. Case Study.

By comparison, plastic packaging such as polyethylene terephthalate PET can have variable permeability to light and vapors, and its reuse and recyclability are currently not comparable with glass.
For example the typical shelf life of beer in glass containers is significantly longer than that of beer in PET bottles. However, the concerns of both consumers and producers of food and beverages extend beyond the material's ability to maintain product freshness.
In the modern globalized marketplace, cost and affordability play an ever-more-significant role. Since its introduction as a viable packaging material, plastics such as PET have continued to grow in popularity.
PET packaging is generally much lighter than glass, reducing the cost and CO2 footprint of product transportation and improving affordability.
The costs of raw materials and production processes for PET packaging manufacture are also lower than glass, on a per unit basis, giving it a further cost advantage. PET can also be combined with other plastics in packaging materials to endow it with different properties.
In some instances, these blended plastics lower the overall packaging weight. Figures 1 and 2, which use data from Packaging World magazine, illustrate the influence exerted by plastic and PET packaging, specifically in the North American beverage market. The main niche retained by glass packaging over PET is the alcoholic beverage sector.
Glass offers lower permeability to O2 and CO2 than plastic, which means alcohol can be stored longer in glass. In the soft drinks sector, this is less of an issue. With the obvious cost advantage, PET has become the dominant packaging material in that sector. Despite the apparent advantages of plastic packaging materials over traditional glass materials, there is a growing awareness of the environmental impact of using plastics.
With this in mind, will the demand for plastic packaging in the future be affected by environmental concerns? Studies often fail to capture the effect of the full life cycle of a product on the environment - especially what happens to packaging at the end of its life cycle.
Even when recycling meets ISO standards, studies of the environmental impacts of materials vary. These life cycle assessments often fail to account for the real life, practical issues of waste disposal and recycling - such as waste collection infrastructure and waste sorting - which leave much of the world's plastic waste in landfill or in oceans.
One source of plastic waste that finds its way into the wider environment originates from the PET packaging industry. In total global demand for PET was Glass, on the other hand, can be infinitely recycled back into glass packaging without any loss of quality.
Therefore, glass recycling has a much more direct impact on demand for new packaging material. Thanks in part to the greater suitability of glass packaging for recycling, in many regions the infrastructure surrounding glass bottle collection and cullet use is much more developed compared than that of plastic collection.
Reuse Opportunities A further issue is that PET is not, at least in the public's perception, infinitely re-useable - although a debate still exists over the impact of reusing plastic bottles multiple times.
There are currently numerous examples, particularly in developing regions where glass bottles are cleaned and reused, that show a reduced demand for new packaging material. The company offers a program in which reusable glass bottles can be returned to the shop in which they were purchased and sent back to the plant for re-use.
A similar initiative is being carried out by Diageo in India, which is the country's largest spirits producer.
SinceDiageo has been collaborating with its glass suppliers to use returnable glass bottles across a number of its most popular brands. The adoption of these initiatives on a wider scale will further demonstrate the environmental advantage of glass as a packaging material compared to plastic.
Public Perception of Plastics for Packaging A recent study by Plymouth University found that a third of the fish and shellfish consumed by humans contained plastic.
With growing awareness of these and similar impacts of the use of plastic packaging and the mismanagement of waste plastic packaging, public perceptions towards packaging are beginning to change.
With it, consumer trends are also shifting. Other studies suggest a consumer preference for glass over plastic as packaging material. It appears as though this overwhelming shift in public perception is beginning to have an impact on the behavior of businesses and legislators.
In the UK, all major supermarkets have agreed to eradicate all unnecessary single-use plastics bywhile the UK government has proposed its own plan to eliminate all avoidable plastic waste by In India, Prime Minister Modi has pledged to abolish all single-use plastics by Case Reports in Plastic Surgery and Hand Surgery Ranked by PubMed Central, this open access journal serves as a forum for case reports in plastic surgery, hand surgery and related research.

Without plastics, modern medicine simply would not exist as we know it. Plastic is a vital part of almost everything that happens today in hospitals, operating rooms, and doctor’s offices.
