• 美国伸展和收缩薄膜市场报告（2015-2019年）
  Stretch and shrink films are used for packaging and protecting goods from damage and spoilage. As these highly engineered polythene films have special chemical properties, they differ from one another in terms of their flexibility and stretchability. Stretch films are thin elastic polythene films that are used to wrap around pallet loads, while shrink films are thin films that are used to wrap around a single product or commodity and require heat for packaging.
• 全球吸附剂市场报告（2015-2019年）
  Adsorbents are materials that have the ability to adsorb fluids and dissolved solids onto their surface. Adsorbents work by creating a layer of adsorbate onto the surface through adhesion. They are used for various industrial applications, including process industries, water purification, and air separation. Adsorbents are of various types and can be broadly classified into zeolite, activated carbon, silica gel, alumina, clay, and metal oxide and others. Adsorbents are increasingly being used to reduce contamination in both air and water during various industrial processes.
• 全球拉伸和收缩膜市场报告（2015-2019年）
  Stretch and shrink films are highly engineered polythene films used for packaging goods. These films have special chemical properties, which make them differ in their flexibility and stretch ability. Stretch films are stretchable, elastic thin polythene films used to wrap around pallet loads. Shrink films are thin films that are wrapped around a single product or commodity and require the application of heat for packing. These films help to prevent the spoilage of goods from air and moisture, thus enhancing the quality of packaged products.
• 全球RO膜市场报告（2015-2019年）
  RO is a technology that uses a semipermeable membrane to remove dissolved salts or organic molecules. The water is pushed using a high-pressure pump through the membrane and allows the passage of water molecules but prevents dissolved salts and bacteria from passing through. The pump capacity required for the process depends on the salt concentration of the feed water. The semipermeable membrane used for the process is mainly made of two materials: cellulose acetate and an aromatic polyamide. In addition, the RO membranes fall into two categories – Asymmetric membranes and thin film composite membranes. While asymmetric membranes contain one polymer, the thin film composite membranes contain two or more polymer layers.
• 全球成人纸尿裤市场报告（2015-2019年）
  Adult diapers are necessary for people suffering from conditions such as urinary or fecal incontinence, mobility impairment, or dementia. The convenience and comfort offered by adult diapers has increased their acceptance among people. The disposable diaper technology has been evolving since the 1970s, and adult diapers are a comparatively recent innovation. The production of adult diapers is a multi-step process in which the absorbent pad is vacuumformed and attached with elastic fibers.
• 全球食品工业膜市场报告（2015-2019年）
  A membrane is a type of selective barrier that is used to separate or concentrate the feed stream as it passes through the membrane, which selectively allows some constituents to pass as others are retained on the surface of the membrane. The constituents that are allowed to pass are known as permeates and those that are retained are known as concentrates or retentates. Different types of membrane are used in the Food industry depending on their pore size. The types of technology implemented for membranes include ultrafiltration, microfiltration, reverse osmosis, and nanofiltration. Other membrane technologies such as membrane contractors, electro dialysis, and pervaporation are also used but their market share is low.
