Polyethylene
is a thermoplastic material composed of polymers of ethylene. It is
normally a translucent, tough, waxy solid unaffected by water and a
large range of chemicals. It is made from petroleum feedstock also known
as hydrocarbons. It is molded to suit a range of applications in the
form of sheets, films, rolls and bags.
Features
Polyethylene films for packaging have a very long life span. They are
tough, chemical and moisture resistant. They are also puncture resistant
so that heavy or sharp edged products do not damage them. They have good
clarity and are easy to work with. They are not affected by temperature
extremes and are UV stabilized. These films are available in clear,
black, and a variety of colors, and they may be made from renewable
resources such as starch, cellulose, or degradable polymers.
Ecological Safety
Polyethylene films are environmentally friendly and not harmful to
foodstuffs. No harmful substances are used during the manufacturing and
the preparation and there are no vapors, which are hazard to health or
drainage systems. These films are biodegradable polymer films, which
have a proprietary additive that allows oxidative degradation breaking
the long carbon chains down into smaller pieces. The oxidative
degradation is triggered by sunlight, heat, and mechanical stress. The
film becomes brittle and the molecular fragments are then further broken
down by microbial action to carbon dioxide, water, and natural
substances.
Installation
Polyethylene films are manufactured in widths of upto 50 feet to suit
an individual’s needs. They have convenient folds that make them
easy to transport and install. The various folds are detailed on the
back of each roll. The polyethylene rolls should not be opened before
installation. They should be installed taking care of each layer to be
placed.
Applications: Polyethylene Films and Packaging
They are found to be ideal for food packaging. They offer specially
good protection to the packaged goods. They can be used for a multitude
of applications and provide protection not only to foodstuffs and
medications but also for screws, bearings, furniture and construction
fittings, spare parts, etc.
They are also used for agricultural and technical applications.
Designed for use in overwraps, horizontal and vertical packaging
applications. Other applications include medical implants, bearings, box
liners, bulk storage, gamma sterilization, pharmaceutical storage,
transport trays, precision parts, gas water filters, machinery covers,
optical parts, and printing plate storage and protection. Various
packaging products made out of polyethylene films are like packaging
rolls, aluminum sheets, aluminum foils, packaging bags, packaging
pouches etc.
