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.
