A Plastic bag is a bag flexible packaging made of thin, flexible, blown poly film. Plastic bags are used for containing waste for packaging, disposal, and for storing and transporting foods, produce, powders, ice, chemicals, etc.
Many plastic bags are shaped like two identically-sized rectangular plastic sheets welded or folded together on 1, 2 or 3 sides, with one side open. This type of shape allows for simple, economic manufacturing and compact storage of the bags before use. Sizes vary from a few centimeters on a side, to several meters on a side, depending the need. Typical properties manufacturers look for when determine the bag material are impact strength, flexibility, low or high temperature properties, cristallinity, resistance to environmental stress cracking, lower melting points and wide processing ranges.
Bags are also made with carrying handles, hanging holes, tape attachments,
security features, paper and other laminations, heavy sacks, pouch and
standup pouch and other shapes. Some bags have provision for resealable
hermetic or non-hermetic closing; others are sealed, often by heating the
open edge, once filled, and can only be opened by destroying the packaging.The
thickness or gauge of the film is expressed in Mil - A unit of measurement
in thousandths of an inch, (i.e., .001 = one thousandth of an inch or 1.0
mil), generally used to designate the thickness of LDPE products; or Mic
- Short for micron, one thousandth of a millimeter, generally used to designate
the thickness of HDPE products.
The Space Bag was originally produced by New West Products, Inc. in
