What is PP Films ？
PROPERTIES Polypropylene or PP is a low cost thermoplastic of high clarity, high gloss and good tensile strength. It has a higher melting point than PE, which makes it suitable for applications that require sterilization at high temperatures. It also has less haze and higher gloss. Generally, the heat-sealing properties of PP are not as good as those of LDPE. LDPE also has better tear strength and low temperature impact resistance. PP can be metallized which results in improved gas barrier properties for demanding applications where long product shelf life is important. PP films are well suited for a broad range of industrial, consumer, and automotive applications. PP is fully recyclable and can be easily reprocessed into many other products for many different applications. However, unl... -
what is PVC compound ?
PVC compounds are based on the combination of the PVC polymer RESIN and additives that give the formulation necessary for the end-usage (Pipes or Rigid Profiles or Flexible Profiles or Sheets). The compound is formed by intimately mixing together the ingredients, which is subsequently converted into the “gelled” article under the influence of heat and shear force. Depending on the type of PVC and additives, the compound prior to gelation can be a free-flowing powder (known as a dry blend) or a liquid in the form of a paste or solution. PVC compounds when formulated, using plasticizers, into flexible materials, usually called PVC-P. PVC Compounds when formulated without plasticizer for rigid applications are designated PVC-U. PVC Compounding can be summed up as follows: The rigid PVC dr... -
Difference Between BOPP, OPP and PP Bags.
The food industry majorly uses BOPP plastic packaging. BOPP bags are easy to print, coat and laminate which makes them suitable for packing products like fresh produces, confectionaries and snacks. Alongwith BOPP, OPP, and PP bags are also used for packaging. Polypropylene is a common polymer among the three used for manufacturing the bags. OPP stands for Oriented Polypropylene, BOPP stands for Biaxially Oriented Polypropylene and PP stands for Polypropylene. All three differ in their style of fabrication. Polypropylene also known as polypropene is a thermoplastic semi-crystalline polymer. It is tough, strong and has high impact resistance. Standup pouches, spout pouches and ziplock pouches are made from polypropylene. It is very difficult to differentiate between OPP, BOPP and PP plas... -
Application Research of Concentrating Light (PLA) in LED Lighting System.
Scientists from Germany and the Netherlands are researching new environmentally friendly PLA materials. The aim is to develop sustainable materials for optical applications such as automotive headlights, lenses, reflective plastics or light guides. For now, these products are generally made of polycarbonate or PMMA. Scientists want to find a bio-based plastic to make car headlights. It turns out that polylactic acid is a suitable candidate material. Through this method, scientists have solved several problems faced by traditional plastics: first, turning their attention to renewable resources can effectively alleviate the pressure caused by crude oil on the plastics industry; second, it can reduce carbon dioxide emissions; third, this Involves consideration of the entire material life c... -

Application status and trend of polylactic acid (PLA) in automobiles.
At present, the main consumption field of polylactic acid is packaging materials, accounting for more than 65% of the total consumption; followed by applications such as catering utensils, fibers/non-woven fabrics, and 3D printing materials. Europe and North America are the largest markets for PLA, while Asia Pacific will be one of the fastest growing markets in the world as demand for PLA continues to grow in countries such as China, Japan, South Korea, India and Thailand. From the perspective of application mode, due to its good mechanical and physical properties, polylactic acid is suitable for extrusion molding, injection molding, extrusion blow molding, spinning, foaming and other major plastic processing processes, and can be made into films and sheets. , fiber, wire, powder and o... -
INEOS Announces Expansion of Olefin Capacity to Produce HDPE.
Recently, INEOS O&P Europe announced that it will invest 30 million euros (about 220 million yuan) to transform its Lillo plant in the port of Antwerp so that its existing capacity can produce unimodal or bimodal grades of high-density polyethylene (HDPE) to Meet the strong demand for high-end applications in the market. INEOS will leverage its know-how to strengthen its leading position as a supplier to the high-density pressure piping market, and this investment will also enable INEOS to meet the growing demand in applications critical to the new energy economy, such as: transportation Networks of pressurized pipelines for hydrogen; long-distance underground cable pipeline networks for wind farms and other forms of renewable energy transportation; electrification infrastructure; a... -
Global PVC demand and prices both fall .
Since 2021, global demand for polyvinyl chloride (PVC) has seen a sharp rise not seen since the 2008 global financial crisis. But by mid-2022, PVC demand is cooling rapidly and prices are falling because of rising interest rates and the highest inflation in decades. In 2020, demand for PVC resin, which is used to make pipes, door and window profiles, vinyl siding and other products, fell sharply in the early months of the global COVID-19 outbreak as construction activity slowed. S&P Global Commodity Insights data shows that in the six weeks to the end of April 2020, the price of PVC exported from the United States plunged by 39%, while the price of PVC in Asia and Turkey also fell by 25% to 31%. PVC prices and demand rebounded quickly by mid-2020, with strong growth momentum through... -
The Shiseido sunscreen outer packaging bag is the first to use PBS biodegradable film.
SHISEIDO is a brand of Shiseido that is sold in 88 countries and regions around the world. This time, Shiseido used biodegradable film for the first time in the packaging bag of its sunscreen stick “Clear Suncare Stick”. Mitsubishi Chemical’s BioPBS™ is used for the inner surface (sealant) and zipper part of the outer bag, and FUTAMURA Chemical’s AZ-1 is used for the outer surface. These materials are all derived from plants and can be decomposed into water and carbon dioxide under the action of natural microorganisms, which are expected to provide ideas for solving the problem of waste plastics, which is increasingly attracting global attention. In addition to its eco-friendly features, BioPBS™ was adopted because of its high sealing performance, processability ... -
Comparison of LLDPE and LDPE .
Linear low density polyethylene, structurally different from general low density polyethylene, because there are no long chain branches. The linearity of LLDPE depends on the different production and processing processes of LLDPE and LDPE. LLDPE is usually formed by the copolymerization of ethylene and higher alpha olefins such as butene, hexene or octene at lower temperature and pressure. The LLDPE polymer produced by the copolymerization process has a narrower molecular weight distribution than general LDPE, and at the same time has a linear structure that makes it have different rheological properties. melt flow properties The melt flow characteristics of LLDPE are adapted to the requirements of the new process, especially the film extrusion process, which can produce high quality LL... -
Jinan Refinery has successfully developed a special material for geotextile polypropylene .
Recently, Jinan Refining and Chemical Company successfully developed YU18D, a special material for geotextile polypropylene (PP), which is used as the raw material for the world’s first 6-meter ultra-wide PP filament geotextile production line, which can replace similar imported products. It is understood that the ultra-wide PP filament geotextile is resistant to acid and alkali corrosion, and has high tear strength and tensile strength. The construction technology and the reduction of construction costs are mainly used in key areas of national economy and people’s livelihood such as water conservancy and hydropower, aerospace, sponge city and so on.
