Density of PP #350*450MM Zip Lock Plastic Bag with Portable handle For Garment Package
The density of PP is between 0.895 and 0.92 g/cm³. Therefore, PP is the commodity plastic with the lowest density. With lower density, moldings parts with lower weight and more parts of a certain mass of plastic can be produced. Unlike polyethylene, crystalline and amorphous regions differ only slightly in their density. However, the density of polyethylene can significantly change with fillers. it included OPP, BOPP and CPP etc.
Plastic bag is an essential item in people's daily life, and it is often used to hold other articles. It's widely used because of its cheap, lightweight, large capacity, easy to storage.
Brief Introduction Of Bags With Different Materials:
Polyethylene (abbreviated PE) or polyethene (IUPAC name polyethene or poly(methylene)) is the most common plastic. The annual global production is around 80 million tonnes. Its primary use is in packaging (plastic bags, plastic films, geomembranes, containers including bottles, etc.). Many kinds of polyethylene are known, with most having the chemical formula (C2H4)n. the PE can be divided with HDPE, LDPE and LLDPE etc.
A polyolefin is any of a class of polymers produced from a simple olefin (also called an alkene with the general formula CnH2n) as a monomer. For example, polyethylene is the polyolefin produced by polymerizing the olefin ethylene. Polypropylene is another common polyolefin which is made from the olefin propylene.
Most polyolefin produced in the industrial scale are made via polymerization through the use of catalysts. One example is the use of Ziegler-Natta catalyst for the polymerization of ethylene to polyethylene.
Polyethylene terephthalate (sometimes written poly(ethylene terephthalate)), commonly abbreviated PET, PETE, or the obsolete PETP or PET-P, is the most common thermoplastic polymer resin of the polyester family and is used in fibers for clothing, containers for liquids and foods, thermoforming for manufacturing, and in combination with glass fiber for engineering resins.
Nylon is a generic designation for a family of synthetic polymers, more specifically aliphatic or semi-aromatic polyamides. They can be melt-processed into fibers, films or shapes. The first example of nylon (nylon 6,6) was produced on February 28, 1935, by Wallace Carothers at DuPont's research facility at the DuPont Experimental Station.Nylon polymers have found significant commercial applications in fibers (apparel, flooring and rubber reinforcement), in shapes (molded parts for cars, electrical equipment, etc.), and in films (mostly for food packaging)
