2.5 Manufacturing Process PolyPet bottle and containers are manufactured using SBM. The company has two manufacturing methods they use to SBM which are Two-Stage process and One –stage method. So, for my project I was interested in Two- Stage process whereby the preform are injection moulded separately before being blown and this process is ideal for medium to large scale production of PET bottles. Figure 4: Flow Diagram of the sequence of Two-Stage SBM process 2.5.1 Manufacturing procedure 1. First, a preform is injection moulded, preform look like a miniature version of final product, comprised of the finished neck with threads and a small, thick walled lower section, which will be blown into final shape.
According to Scholastic News, “Only about fourteen percent of single-serving plastic water bottles are recycled.” This means that eighty-six percent of all single-serving plastic water bottles are in landfills or polluting our communities. If everybody at our school was to only use one reusable bottle, that would dramatically cut our bottles that end up in the trash. Since over one billion plastic bottles end up in our landfills every year, this means that each person uses about thirty five plastic water bottles every year. Our school has around seven hundred students, so all using reusable water bottles could make for over ten thousand water bottles not in our
PET Plastics – Polyethylene terephthalate (PET) are made for two primary processes for producing a PET package are - 1) Thermoforming. 2) Blow Molding. 1) Thermoforming- It ia process by which a sheet of PET plastic is heated and shaped using a mold into the desired shape. 2) Blow Molding – It is typically used to make containers with narrow mouths.

First, as Doria (2010) notes, twenty to twenty-five percent of the bottled water comes directly from tap water without any form of purification through distillation of any other treatment. This means that 25 to 40 percent of the bottled water is not any different from the tap water only that it has been exposed to or has a high concentration of the chemicals used to manufacture the packaging plastics. Due to the pathetically primitive regulation of the bottled water, the manufacturers are not keen to inform the consumers of the contaminants that are present in their water. According to Warburton (1993), consumers are likely to drink bottled water containing contaminants such as E.coli, asbestos, giardia, bromate and many other industrial chemicals and pathogens. Arnold & Larsen (2006) indicate that ten water brands in the US had thirty-eight
Water bottles, a major controversy in the world of recycling and on the other hand litter. Do you know what happens in our oceans and world when plastic is thrown out or littered? There are many dangerous and harmful effects when this happens. Water bottles are creating a pile of trash in the ocean and on land, and to top it all off we’re the ones who started and created this disaster. I think that plastic water bottles should be banned because it’s pricey and expensive to the economy and to the public, they are lethal to animals, and plastic water bottles are polluting our environment.
Plastic Wine/Beer Bottles Description of the Product One of the five ideas we have chosen to expand upon is plastic wine/beer bottles. These plastic bottles would be a substitute to the widely popular glass wine/beer bottles that are used today. Plastic bottles are cheaper to produce and are more durable than their glass counterparts. Plastic bottles would be ideal at large public events, such as sporting events as they do not break as easily nor in the same way as glass bottles. This would help to create a safer environment for people attending these events and would allow the organizers of these events to refrain from purchasing third party plastic drink cups.
Actually over half of bottled water is tap water that has been repackaged. Bottled water causes the air to be polluted yearly. Bottled water is not tested often. Also, when those bottles that the water is packaged in sits in heat the plastic releases chemicals into the water that can cause people to get sick. Therefore, tap water is the route to go.
INTRODUCTION Plastic water bottles are not always safe to be reused over and over again because the harmful chemicals in the bottle may absorb into the contents. According to The Green Guide( website and magazine devoted to greener living) which owned by the National Geographic Society, the safest plastics for repeated use in storing food is the one which made from high-density polyethylene (HDPE), low-density polyethylene (LDPE) and polypropylene (PP). So, our water bottles are made of polypropylene (PP) and as it considered to be safe for repeated use storing food items and cycling through the dishwasher. Not just safe to use, our water bottles were also improved with the addition of phosphorescent pigment in colouration of the plastics.
The problems is plastic waste, and more specifically, plastic water bottle waste. The majority of the plastic waste comes from efficient packing of water that people buy everyday. We can reduce harmful plastic water bottle pollution by using refillable bottles, as well as educate the public on the dangers of plastic waste. A major problem with the whole plastic bottled water epidemic is that people are tricked into thinking bottled water is safer than tap water when in reality that is not the case. There have been many studies done and it’s been concluded that it is typically the opposite of the everyday myth.
For every six plastic bottles bought, only one is recycled – five are thrown away to eventually end up in landfills, or the ocean (Ellsbury, 2013b). Plastic bottles take one hundred years to decompose. One of the most obvious impacts of plastic bottles is what happens after the water has been consumed (Ellsbury, 2012). In every second of the day, more than five thousand of people open plastic bottle of water. A robust and united community can be chipped in by a strong community green projects and programs.
