Bags and sacks are used for storage, packaging, transportation, and shipping applications. Plastic bags, made of thin, flexible, plastics film, are extremely popular in everyday usages of containing, protecting, and transporting foods, produce, powders, ice, chemicals, waste, components, electronic accessories, and almost all small objects.

Disposable plastic bags are often heat sealed together. Some plastic bags are bonded with adhesives or are stitched. Reusable plastic bags may have stronger bonding and thicker materials to provide strength for the wear and tear in use. Shrink-wrap is another form of plastic bag by applying heat to the wrapping plastic sheets to shrink around the object.
