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.
Widely used for packing:
gift,stationeries,jewelry,accessory,cosmetic,bread,garments and so
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
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.
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)
