The wonderful thing about zip lock bags is that they can be used more then one time, which makes those that have purchased them feel like they are getting their money’s worth as well being an environmentally friendly product. Any item that can be reused numerous times is considered environmentally friendly, particularly when the plastic that makes up the item, such as the thermoplastics that are the usual materials for plastics bags, are able to be melted down and remanufactured too. The part of the zip lock bag that allows it to be used more then once is the closing mechanism.
Among the materials used to create plastic bags in their many forms is polyethylene, one of the major plastic bag substances. Polyethylene bags have many positive characteristics that are very similar to the other major poly bag substance, polypropylene. The
A Sonotube is a brand of rounded construction column made with a cardboard core. The inside of the core is a type of concrete masonry form that is easy to cut and has a variety of uses. The Sonotube is one of the most popular forms of concrete masonry tubing because it is versatile and has many advantages that make it easy to use. The use of Sonotubes have a variety of advantages to the construction process, including:
Paper tubes are a part of everyday life. If you have ever purchased wrapping paper, tape, fabric on a roll, toilet paper, or paper towels, then you have seen paper tubes in your own home. If you look a little deeper, you will probably find other areas where cardboard tubes are also used in your home or office on a daily basis.
There an array of industrial processes today that produce a lot of hazardous waste. From nuclear power plants to leftover drug chemicals created from the medical and pharmaceutical industries, proper hazardous waste disposal is essential to avoiding potential catastrophes. A number of chemicals can even be found in the average American household, such as battery acid, that can lead to disaster if not properly handled. Luckily, there is a system in place to deal with harmful waste.
Fiber drums first appeared on the market in the first half of the 20th century. The drums were an innovative packaging solution to provide for a lighter container. Today, the packaging/container market is filled with fiber drum manufacturers. Occasionally referred to as cardboard drums, fiber drums are commonly made from fiberboard. They have a fully removable lid that is made out of either fiber, plastic or steel. This lid allows full access to the drum and whatever is contained inside.
Vacuum forming is a simpler process than injection molding, involving less equipment for the production of parts and requiring less tooling. Vacuum forming companies offer services that are economical yet still give customers the desired design flexibility for a wide range of plastic products because of low-cost tooling modifications. If you are looking for a cost-effective process for creating three-dimensional plastic products with sharp, precise details plus the option for trim and other visually appealing decoration, vacuum forming might just be the ticket. Known as a thermoforming process because it utilizes heat to make the plastic sheet or film pliable enough to form over and around a mold, vacuum forming serves industries such as food, cosmetics, medical, electronics, consumer products, toys, athletic equipment, appliance, automotive, office supplies, etc. The packaging industry deserves a separate mention because it relies heavily on vacuum formed items such as blister packs, inserts, trays and clamshells, all of which act to hold products in place as part of overall packaging protection, plus offer aesthetic appeal.
This paper attempts to identify some of the specifics of the process used to obtain approval for use of plastic pallets as equivalent to wood pallets for use in warehouse storage. This paper is written to look at the issue in general and is not intended to cover all storage situations. Your specific situation should be evaluated by a fire protection specialist. Most plastic pallets are molded out of polyolefin materials such as high density polyethylene or polypropylene. These materials are more flammable than the wood used to make pallets. Over the years the industry has argued with the fire protection establishment that plastic pallets, while they burn hotter than wood, are much more difficult to ignite. Fire protection people counter with the fact that most warehouse fires are arson and if an arsonist wants to start a fire they will do what ever they need to do to get a fire started.
Plastic bags, also called ‘poly bags,’ are one of those modern conveniences we take for granted. But 60 years ago, no one ever considered the question, ‘Paper or plastic?’ Back then, people also managed to get by without Ziploc® bags or dry cleaner bags. This was because the technology for creating polyethylene film didn’t emerge until the 1940s during World War II. And the methods to create plastic bags from polyethylene film weren’t developed until the 1950s. The most common way to produce poly bags is by blown film extrusion, also called the ‘tubular film process.’ In a moment, you’ll see how it got this name. Plastic bags are made from polyethylene. During processing, the polyethylene might be treated with any number of additives, such as…
