In digital printing on flexible plastic, the surface of flexible plastic materials is printed based on the data stored on a computer in digital form. Flexible plastic contributed around 14.78% to the global digital printing packaging market in 2016. A majority of the demand is from label printing and flexible film printing in different types of pouch packaging. Inkjet printing, xerography or electrography, and thermal transfer printing (TTP) are the commonly used digital printing types for flexible plastic. The market also consists of other types of digital printing technology such as ionography, direct thermal printing, tone-based printing, and magnetography.

A membrane acts as a selective barrier that separates and concentrates the feed stream, allowing the constituents to pass while impurities are retained on the membrane. The constituents that pass through the membrane are termed as permeates, and those that are retained are known as concentrates or retentates. The selection of membranes for specified applications depends on the pore size of the membrane. Ultrafiltration, microfiltration, reverse osmosis, and nanofiltration are some of the membrane filtration technologies. Other membrane technologies such as membrane contractors, electrodialysis, and pervaporation are also used; however, their market share is low.

Packaging sacks are standardized, flexible bulk bags used for industrial packaging of dry, lose, or granulated materials. They are used for protecting, storing, transporting, and handling of goods in large quantities from manufacturing centers to distribution centers, where they are packaged for customers. Packaging sacks are made using plastic, paper, or jute in different weights and strength parameters. The containers are suitable for numerous applications required in the construction, chemical, and food sectors. The market is characterized by innovative offerings and customizations aligned with specifications provided by the customers.

格局：全球整体稳定，中国变数最大；国内群雄割据，尚无执牛耳者。轮胎是 成熟期行业，当前已形成由品牌决定胜负，以三巨头+八大跨国集团为主、集中 发展的竞争格局；预计未来增速将长期保持在 2~5%。中国轮胎工业起步晚但 发展快，用 10 年时间把全球份额从 5%提升至 20%，是全市场最大变量，预计 未来 3 年需求复合增速在 15%左右；然而，大而不强、多而不合、结构性过剩、 无行业领袖等问题是国内轮胎产业再上台阶的最大桎梏。
