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%
