Trash bags

Film (packaging, trash bags, household wrap, drapes, tablecloths), 59% extrusion coating, 17% injection molding (squeeze bottles, toys, kitchen utilityware), 6% wire and cable, 4% adhesives and sealants, 4% miscellaneous, 10%... 

Fibrillation can be achieved mechanically by drawing and pulling thin sheets of polymer. This is compounded if twisting is also involved. A rough idea of this process can be demonstrated by cutting several ribbons of film from a trash bag. Take one and pull. It will elongate and eventually form a somewhat thick filament-like material. Do the same to another strip but also twist it. 

LDPE has branching and is less crystalline, more flexible, and not as strong as HOPE. The greater amount of amorphous character makes it more porous than HOPE, but it offers a good inert barrier to moisture. It is a major material for films from which trash bags and bread bags are made. 

LDPEs are flexible and include numerous plastic items such as plastic wraps (cellophane), grocery and trash bags, and diaper lining. 

This explosives volatile nature can be overcome to some extent by enclosing the mixed explosive composition in something impervious to gasoline. Large trash bags would serve this purpose. The explosive would need to be used quickly, however, as this measure would not be enough to ensure the explosives loss of sensitizer to evaporation. Better explosive composition can be had, but this one would work and is powerful ... 

This explosive can be just poured into the bore hole if water is not present. It will work in a wet environment, but the longer the exposure to moisture, the less performance can be expected. The best application in a wet bore hole is to place the slurry in a poly ethylene tube or a trash bag to protect the explosive from the adverse affects of the water. 

For flexible film applications such as carrier and trash bags PLA has the potential to replace LDPE and HDPE bags when a compostable solution is desired. Furthermore, the high water vapour transmission rate of PLA is beneficial for fresh food applications where it is important that the water vapour escapes quickly from the packaging. PLA also reduces fogging on the lid of the packaging. 

The Heritage Bag Company is a privately owned business which manufactures a range of plastic bags. Products include polyethylene trash bags, healthcare waste disposal bags and bags for food. 

Polyethylene is, by a wide margin, the largest volume synthetic polymer made by mankind. As of this writing, about 77 million metric tons are produced annually and the growth rate is expected to continue at about 5% per year into the foreseeable future. Within the three minutes or so it takes to read this preface, over 400 tons of polyethylene will have been manufactured. It is produced in various forms on 6 continents and its applications are ubiquitous in daily life, from the trash bag you placed on the curb this morning to Uncle Fred s artificial hip.

Recycling of unwanted polymers is the best solution, and six types of plastics in common use are frequently stamped with identifying codes assigned by the Society of the Plastics Industry (Table 31.2). After sorting by type, the items to be recycled are shredded into small chips, washed, dried, and melted for reuse. Soft-drink bottles, for instance, are made from recycled poly(ethylene terephthalate), trash bags are made from recycled low-density polyethylene, and garden furniture is made from recycled polypropylene and mixed plastics.
