Fusing hot sand and scrap plastic film and bags into structures and sculpture, cause, why not
Plastic film, which provides 39 percent of all plastic packaging, is a thin-gauge packaging used as a bag or wrap. Examples include plastic grocery sacks, trash bags, dry cleaning garment bags and plastic or stretch wrap. Plastic film is less than 10 mils thick, averaging 0.7 mils to 1.5 mils. A mil is 0.00l inch.
Most plastic trash bags are less than one mil thick.
Almost 40% of plastic produced is film
Recycling plastic film is difficult because the manufacturing process uses diverse resins and colors. Most bags, sacks and shrink wrap are made from low-density polyethylene (LDPE), linear LDPE or high-density polyethylene (HDPE). Polypropylene and polyvinyl chloride (PVC) also are used.
Additionally, many films blend or co-extrude two or more resins. Individual product characteristics may create remanufacturing problems. For instance, stretch wrap requires a "tackifier" so that it can cling, yet this quality is not desired in a bag.
Because plastic film does not degrade, degradable plastics are a proposed substitute. However, "degradable" bags will degrade slowly, if at all, in a modern landfill. As a result, a Florida requirement that plastic bags be degradable was repealed.
