Glass is one of the most trusted and tested
packaging materials in terms of health, taste and the environment safety. It is
made from readily-available domestic materials, such as sand, soda ash,
limestone and cullet. It maintains the purity of food & beverages and
preserves a product’s taste or flavor. It is 100% recyclable and can be
recycled endlessly with no loss in quality or purity. Additionally, it consists
of a single material, which reduces consumption of raw materials, extend the
life of plant equipment such as furnaces and saves energy.
Glass has no crystalline structure. When it is
free from stresses, it is optically isotropic. Its optical properties relates
to degree of penetration of light and subsequent effect of transmission or
wavelength. Its spectral transmission is determined by reflection at the glass
surface and optical absorption.
According to study, “Global
Glass Packaging Market Research Report - Forecast to 2022” some of the major companies that are
working in the global glass packaging market are Owens-Illinois Inc., Ardagh
Group, Vidrala S.A., BA Vidro, Gerresheimer AG, Vetropack Holding Company,
Stolzle Glass Group, Verallia, Piramal Enterprises Limited, Wiegand-Glas GmbH,
ZIGNAGO VETRO S.P.A., VERESCENCE, Luigi Bormioli Corporation, Vetrobalsamo
S.p.A.
Glass is nonporous and impermeable, so there
are no interactions between glass packaging and products to affect the flavor
of food and beverages. It has an almost zero rate of chemical interactions
ensuring the products inside a glass bottle to have their strength, aroma, and
flavor.
The glass packaging market is mainly driven by
various factors such as increased consumption of beverages, especially
alcoholic beverages, and carbonated soft drinks. Some characteristics of glass
packaging are zero chemical leaching, malleability and the non-reactive nature.
Glass manufacturing involves several process,
which depend on the type of glass container, for mixing & melting, forming
processes, wide mouth press & blow, narrow neck press & blow, annealing
and surface treatments. Glass packaging keeps the products safe and healthy for
longer periods because glass is non-reactive with many consumable and
non-consumable products. Glass has a number of properties such as sterility,
chemical inertness, and malleability, and water-resistance, which make it more
appropriate for packaging a variety of perishable and non-perishable products.
On the basis of product, glass packaging
market is segmented into standard glass quality, premium glass quality and
super premium glass quality. On the basis of application, market is segmented
into beverage packaging, pharmaceutical packaging, food packaging and personal
care packaging. Beverage packaging is dominated the market during the forecast
period.
Some of the basic principles of glass’s
fracture analysis or diagnosis of the cause of breakage such as internal
pressure resistance, vertical load strength, resistance to impact and
resistance to scratches & abrasions. Internal pressures produce bending
stresses at the outer surface. Internal pressure resistance is important for
bottles for carbonated beverages, because the bottle is processed in boiling
water or in pressurized hot water. Vertical load strength is defined by the
shoulder design is important in minimizing breakage during high-speed filling
and sealing operations. There are two forms of resistance impact: moving a
container contacting a stationary object and moving object contacting
stationary bottles. The global glass packaging market is expected to progress at
3.2% CAGR during the forecast period. In 2017, the Asia-Pacific was the leader
of glass packaging market, with 34.3% share, followed by Europe and North
America with shares of 27.9% and 22.0%, respectively. This market is expected
to grow USD 61.2 billion by the end of 2021 at a CAGR of 4.3%
