Although there are a number of chemicals that are used to modify the COF the two main ones used in Polyethylene and Polypropylene are Erucamide (which is considered a slow bloom) and Oleamide(which is a fast bloom). The materials are sometimes called primary amides. Slip is a very efficient molecule it has been added to a plastic film in very low concentrations typically 500 to 1500 parts per million (PPM).The slip additive can be let down at the levels of 1 to 3% by weight in blending while extruding the plastic film. Slip molecules are very low in molecular weight as compared to the polymer in which they are used. These molecules are somewhat incompatible because of their nature. This means the material is bi-polar and has one end that has a positive charge and the other has a neutral charge. This incompatibility causes the molecule to migrate referred to as bloom through the polymer to the surface of the plastic film.

This is partly because plastic can be contaminated with other materials and the cost of processing this can outweigh the cost of producing more plastic so compared to other materials like glass and paper, there are fewer places to recycle plastic. However, plastic is lightweight and highly versatile and one way round this is to re-use plastic within the home.

Unless you are very familiar with this type of equipment, you could be setting yourself up for a serious injury. If the repairs aren't completed correctly, you also can cause additional damage, which could end up costing much more than you originally thought. It's best to choose the right company and leave this job to the professionals.Welcome to the world of plastic fantastic!

Not everything is in the hands of politicians and men of power. Me and you, we could be considered ordinary citizens but the "ordinary citizens" have their tools, weapons and voices. Together we can make a difference.

What happens here is that the weight sits on the bottom and the plastic worm floats about a foot and a half above, kind of like waving in the breeze, so to speak. The "lift & fall" retrieve is still the preferred. Try a few different retrieves to see what works for you.

Solutions are constantly being sought and although more and more supermarket chains and retailers are now issuing biodegradable plastic bags, this in itself can be a problem as many people might think that it is ok to just throw them away as they will eventually break down, which is not always the case. Some of these biodegradable bags rely on sunlight to break them down so if they are thrown away as part of household rubbish and end up in a landfill site, they will not degrade because there is no light.
