It is estimated that 3.4 billion tonnes of plastic packaging were created between 1950 and 2017. [1] Most plastic packaging is disposed of within a relatively short time. Discarded packaging accounts for 46% (158 million tonnes) of total annual plastic waste generation. Most plastic packaging waste is estimated to come from household waste.
The British used a plastic explosive during World War II as a demolition charge. The specific explosive, Composition C, was 88.3% RDX and 11.7% non-oily, non-explosive plasticizer. [8] The material was plastic between 0 and 40 °C (32–104 °F), but was brittle at colder temperatures and gummy at higher temperatures.
Plastic milk containers are plastic containers for storing, shipping and dispensing milk. Plastic bottles , sometimes called jugs , have largely replaced glass bottles for home consumption. Glass milk bottles have traditionally been reusable while light-weight plastic bottles are designed for single trips and plastic recycling .
HDPE is known for its high strength-to-density ratio. [4] The density of HDPE ranges from 930 to 970 kg/m 3. [5] Although the density of HDPE is only marginally higher than that of low-density polyethylene, HDPE has little branching, giving it stronger intermolecular forces and tensile strength (38 MPa versus 21 MPa) than LDPE.

An overview of ranges of mass. To help compare different orders of magnitude, the following lists describe various mass levels between 10 −67 kg and 10 52 kg. The least massive thing listed here is a graviton, and the most massive thing is the observable universe.
One cup of low-fat milk has 8 grams of protein and 100 calories, while Greek yogurt provides 15 grams of protein in a small 5.3-ounce container. As for cottage cheese, half a cup has about 12 ...
A water bottle. Worldwide, 480 billions of plastic drinking bottles were sold in 2017 (and fewer than half were recycled). [1] A plastic bottle of antifreeze Large plastic bottles of water. A plastic bottle is a bottle constructed from high-density or low density plastic. Plastic bottles are typically used to store liquids such as water, soft ...
