Somewhat oversimplifying it a DVD (or CD) is a sandwich of two outer layers of polycarbonate plastic with a microscopically thin layer of aluminum, tantalum, or a optically reflective low melting point plastic between the outer layers. Standard factory made read only disks use aluminum in this inner layer for durability, the writable disks use either tantalum or a plastic in this inner layer to permit writing with the LASER as well as reading (which is used depends on the method of writing used).
Pencil cases are often made from plastic because it is lightweight, durable, and more affordable compared to other materials. Plastic also provides a waterproof and easy-to-clean surface, which is helpful for protecting the contents of the pencil case.
Yes, the product is made of solvent-resistant plastic.
Yes, nunchucks can be made completely of plastic. However, plastic nunchucks may not be as durable or provide the same weight and feel as traditional wooden or metal nunchucks. It is important to consider functionality and safety when choosing the material for nunchucks.
Plastic pens are typically made of a combination of materials, including a plastic barrel, ink cartridge, and metal components such as the clip and tip. The plastic used in pens is often a type of polymer such as polyethylene or polystyrene, which provides durability and flexibility.
Glow sticks are generally made of a fairly tough but flexible translucent outer casing of plastic, and an inner capsule of thin glass. The pair of chemicals that are responsible for the chemiluminescence are held inside and are kept separated until the glow stick is deployed. One of the chemicals is inside the glass capsule, and the other is "around" it inside the plastic case. The idea is to get one of the chemicals needed to make the "glow" isolated inside the plastic case, and then allow the other chemical to be "around" the glass capsule and inside the plastic. That way when someone bends the plastic case or strikes it sharply on a hard surface, the glass capsule will break safely inside and release the chemical it held. The two chemicals then combine and the chemical reaction produces light.
A case made from plastic.
It's made out of plastic and metal case components, electronic components on a circuit board, motors to rotate the disc and move the laser and then of course the laser itself which reads the data from the discs.

When a person purchases a DVD it is usually over wrapped in plastic. Once you get through the plastic wrap some DVDs are also housed in a cardboard box to protect the plastic case.
It's a clear plastic case for DVD's or CD's.

It depends on the DVD. Average is 1-1 and a half hours.It should say either on the disc, or on the plastic case that contains the disc.
Generally speaking a DVD O-Sleeve is usually made of a hard flexable plastic like material and being a receptacle having four sides in which a DVD Case is contained within. The DVD case is able to be inserted and withdrawn from the O-Sleeve. Essentially it is a protective case that envelops the DVD case on four of the six sides with openings on opposite ends. Resulting in a six-sided case housed inside a four-sided case. Lenticular printing artwork or electronic components capable of producing sound effects can thus be incorperated into the O-Sleeve eliminating the necessity of having to retool a standard DVD case to comply with artwork/electronic component changes during production.
