The global insulated packaging market is influenced by demographic trends, such as growing urbanization, population growth, an increase in international trading activities, and industrialization. The various types of insulated packaging products include boxes, containers, bags, pouches, and wraps.

Compressors are mechanical devices that compress air or gas in a sealed unit and deliver it at the desired pressure levels. Compressors are categorized as air compressors and gas compressors. An air compressor is a device that compresses and pressurizes air and thereby, converts its potential energy into kinetic energy. A gas compressor is a device that reduces the volume of gas to increase its pressure following the principle of Boyle's law. An air compressor is a distinct type of gas compressor. Compressors are used in several applications across the oil and gas, petrochemicals and chemicals, power generation, desalination, water and wastewater treatment, mining and cement, and fertilizers industries. The major types of compressors considered in this report are centrifugal compressors and positive displacement compressors.

There is a continuous demand from food manufacturers to extend the shelf life of food products without compromising their chemical and physical properties or adding any unnatural ingredients. The popularity of preservation through modified atmosphere packaging is rapidly growing worldwide. It is an efficient and natural preservation method that complements alternative preservation methods.

Liquid packaging board has a high barrier coating to contain the liquid. It also resists the air and flavor from the paperboard to mix into the contained liquid. Manufacturing companies make continuous innovations for creating economic and environmentfriendly packaging. Several layers are used to form a liquid packaging board. Plastic-coated carton board provides a light barrier and firmness. It is fabricated from three-layer technique, in which chemo-thermo-mechanical pulp (CTMP) is used in the central coating. Depending on the requirements several materials are used for coating.

我国休闲食品市场规模近五年复合增长率达10.51%，但与欧美日韩等国家相比仍存在较大差距。从消费品类上看，坚果等高端产品量价齐升，饼干等传统低价产品增速明显下降，休闲食品领域消费升级现象明显。从零售渠道上看，受益于丰富的产品品类、方便的购物体验与较高的品牌识别度，连锁经营模式与电商模式的市场份额正逐步扩大，线上线下融合成为趋势。我们认为打造明星产品、增强供应链管理能力、注重消费者体验是休闲食品零售行业取得成功的三大关键因素。

There has been an increase in environmental hazards because of the improper disposal of packaging waste. Burning packaging waste generates carbon dioxide, which is one of the most concentrated greenhouse gas. Improper dumping of waste in landfills has also led to the emission of harmful greenhouse gasses such as methane that are more harmful to the environment than carbon dioxide. Adoption of recyclable or eco-friendly packaging is one of the methods to combat greenhouse gas emissions.>

Food manufacturers are always looking for ways to improve product safety and extend the shelf life of products through the use of better packaging materials, such as vacuum packaging, without altering the physical or chemical properties of foodstuffs, or adding any preservatives. Vacuum packaging is growing in popularity worldwide. It can also complement alternative preservation methods. In such packaging, food is enclosed in a package from which oxygen is removed prior to sealing. This helps in increasing the shelf life and maintaining the quality of food.
