compositions and polyethylene (PE)-coated pouches in today’s market (Robertson, 2012, p.514). It is dependent on the type of materials that the packages can reduce the impact of the light-induced deterioration of milk quality and flavour. Also, the use of pigments, or colours, in printing and packaging process is proven to be effective in protecting milk from light-induced deterioration (Robertson, 2012, p.514). • Yogurt & Cream The most common plastic material in yogurt packaging is thermoformed High Impact

move. An object at rest stays in place unless a force is brought to it. 2nd law; force equals mass times acceleration (F=ma). 3rd law; every action has the same opposite reaction towards the first action. Generally increasing temperature lowers the density and viscosity, so it decreases the air resistance (Qoura.com). Handkerchiefs can be made out of any materials such as cotton, cotton-synthetic blend, synthetic

Groundwater contamination is nearly always the result of human activity. In areas where population density is high and human use of the land is intensive,groundwater is especiallyvulnerable. Where chemicals or wastes may be released to the environment, either intentionally or accidentally has the potential to pollute ground water. When groundwater becomes contaminated, it is difficult and expensive to cleanup. Ground water can be contaminated by human activities and also natural causes when the

of high density polyethylene (HDPE). The HDPE is used in making the plastic bag and shampoo containers since it has long virtuality and unbranched polymer chains which make it more dense as well as very crystalline hence stronger (Nicholson 1997). The HDPE is stiff, strong, tough as well as resistant to moisture. Plastic wraps Plastic wraps comprises of low density polyethylene(LDPE). The LDPE polymers have a crucial chain branching comprising extended side restraints hence being less density as

Therefore, it is important to adopt synthetic membrane with better anti-seepage performance. There are ten-odd types of synthetic membranes developed worldwide, including high-density polyethylene (HDPE), low-density polyethylene (LDPE), polyvinyl chloride (PVC), and chlorinated polyethylene (CPE). These synthetic membranes have an extremely low permeability with a seepage coefficient of ≤1 × 10-12 cm/s [4]. With its strong resistance to chemical corrosion, mature manufacturing

bottles, packaging, cups etc.), but they also are found in durables (e.g. tires, building materials, furniture, etc.) and disposable goods (e.g. medical devices). Diversity of plastics applications is related with their specific properties, low density, easy processing, good mechanical properties, good chemical resistance, excellent thermal and electrical insulating properties and low cost ( in comparison to other materials) [1]. Polyesters are a class of synthetic polymers built up from multiple

processing of thermoset category of plastics like high amount of flashes, mold material abrasion at relatively faster rate as compared to thermoplastics material,

plastic bags and other kinds of wraps destroy marine life. However, according to the U.S Environmental Protection Agency plastic bags and other wraps only account for about 1.6 percent of the municipal solid waste materials. In addition, high-density polyethylene (HDPE) bags, the most common kind of plastic bags, contributes to the waste for only about 0.3 percent. It'd be

used for labeling, packaging, textiles, and stationery. In 1957, the crystallization of polymer was discovered. Soon fabric was made from the polymer, and was in high demand. It can also be used for moldings of cars, film, tape, foam and carpet. Polypropylene can not be glued to any objects or itself, and so it is melded. After Polyethylene, Polypropylene is the highest produced synthetic plastic. Polypropylene also holds up well over time, which is one of the reasons that it is the second most produced

world consistently demonstrated that plastic materials make up 60-80% of marine debris. That little dolphin or penguin who accidently ingests that one plastic bag will die a slow death because they didn’t know better. One of the sites that have a density of 700 plastic debris is the North Sea in Europe. Currently, only Ireland has banned plastic bags and the United Kingdom put a 5-pound tax on plastic bags. All the other states surrounding has done anything about it yet. This is not okay because plastic
