In December last year, China Packaging Federation formulated the “China Packaging Industry Development Plan (2016-2020)â€. The plan points out that by 2020, the localization rate of green and high-performance packaging materials will reach more than 35%; more than 60% of food and drug packaging production information can be inquired, the flow can be traced, the responsibility can be traced, and the expired can be recalled; some high-end Packaging products and related technologies have reached the international leading level. By then, the annual revenue of China's packaging industry is expected to reach 2.5 trillion yuan.
As one of the four major packaging materials, China's plastic packaging business (including plastic packaging boxes and containers and plastic packaging film) revenue in 2015 was about 274.9 billion yuan, accounting for more than 15% of the packaging business. Plastic packaging is also leaping in the direction of green, smart and efficient. Plastic is one of the four basic materials for packaging, and packaging is the largest area for plastics applications. In order to meet the demand for packaging, such as reduction, reliability, responsibility, and individuality, innovative materials and processes are constantly emerging.
Food and beverage packaging
According to UK market research firm Smithers Pira, the global soft plastic packaging market will grow at an average annual growth rate of 3.4%, with 70% demand coming from the food industry, reduction, lightweight, barrier technology, and biology. Degradability and sustainable development have become major trends.
In order to further strengthen food safety supervision, the National Health and Family Planning Commission and the Food and Drug Administration jointly issued the “General Safety Requirements for Food Contact Materials and Products in Food Safety†(GB4806.1). -2016), covering 53 relevant standard systems. Among them, the plastic resin for food contact, plastic materials and products, rubber materials and products, and a variety of organic substances that are potentially harmful to the human body have been clearly defined. The introduction of this regulatory system has attracted great attention from the industry and will play an important role in promoting the safety of food packaging materials, including plastics.
In addition to safety, innovation and personalized design are the focus of food and beverage companies, and innovative packaging has been launched to match product appeals and promote sales. For example, Nongfu Spring has launched a cylindrical square “tea π†innovative bottle type, which has been listed for one billion months and became one of the most successful large single items in 2016.
Daily packaging
The innovation of daily chemical product packaging lies mainly in functional packaging. In addition to the protective function, it is also required to gradually improve its safety and convenience. High oxygen barrier materials, moisture-proof materials, anti-counterfeiting and smart packaging are the main development directions. For example, the HD sunscreen bottle that won the 2016 DuPont Packaging Innovation Gold Award has three innovations: the fine mist nozzle, the easy-to-open “lock†and the wand technology that allows the nozzle to rotate freely, which is practical and beautiful.
Environmental protection, miniaturization of packaging or light weight have gradually become an important factor in daily packaging. In addition, packaging companies use more degradable and recycled materials, and recycle and recycle packaging waste.
Pentaerythritol is mainly used in the coatings industry, can be used to manufacture alkyd resin coating, can make the coating film hardness, luster and durability.It also USES up with anger paint, lacquer and printing ink of pine resin needed raw materials, coating and drying oil, smoldering sex and aviation lubricating oil and so on.
Also used in medicine, pesticide and so on production.Pentaerythritol molecules containing four hydroxymethyl equivalent, with high symmetry, so the production raw material is often used as multifunctional compound
By its nitrification can produce pentaerythritol tetranitrate (taian, PETN), is a kind of high explosives;Esterification available pentaerythritol three acrylate (PETA), used as a coating.
