Polythene is a widely used polyolefin. A thermoplastic material; it is known for being one of the best vapour barriers. This property is exploited by making use of polythene as a protective covering for products and for the outer cartons. Thicker sheets of polythene are also used in construction, laid over concrete to form a protective barrier against ingress of moisture. It is low in cost compared to other polymers.
Polythene sheets also find use as flooring, protection for countertops and window films. On larger scales, these sheets are used in shipbuilding in order to prevent toxic chemicals from contaminating sea water. Large sized sheets can line water tanks to prevent water from seeping inside and these sheets can be used in waste water treatment tanks to prevent toxic chemicals from contaminating the environment. While thin films of high-density polythene are used as vapour barriers for product packaging, heavier and larger packaging and wooden boxes can be lined with sheets of low density polythene or medium density polythene before being sealed to provide protection to machinery or other boxes packed inside a container or a crate. In one word, polythene is versatile.
The basic qualities of this versatile polymer can be enhanced with the use of additives during production. Additives endow the sheet with anti-static property, UV resistance, linear rich property and slip-coefficient enhanced for specific applications. Using the right type of polymer and with the right property does make a difference to its use.
It may not always be possible to source LDPE, MDPE or HDPE sheets from a single source or ask for specific enhancements because most dealers of packaging materials cater to only one segment. However, you can still find packaging specialists offering the widest range of sheets of polythene to suit virtually all types of users. Such a specialist may offer the plain sheets in LDPE/MDPE/HDPE types and additive enhanced sheets. He may also offer end products such as bags and printed packaging made out of this versatile polymer. Whether it is a small retailer looking for limited quantities of PE bags or a construction company looking for thicker gauge PE in larger quantities, one source can satisfy all of them and that is Focus Packaging.
