Plastic is the most common synthetic material that's used for manufacturing consumer goods. Affordable and easy to mass produce, plastic is the number one choice for making just about any simple product. Containers are usually made from this durable and reliable material. First of all, the chemical composition of plastic consists of tight matrices that prevent any fluids and other substances from passing through. Therefore, plastic is very effective at keeping out water and other flowing liquids.
For tight seal applications, it's important to prevent any moisture from entering an enclosed container. Food should be kept well in containers that have proper lids with a strong seal. Sometimes, it's desirable to maintain a certain amount of moisture inside a container. Therefore, plastic is effective at keeping in a moist environment in an enclosing of any size. This versatile material is also effective at containing odors, especially of food and chemicals. Homeowners often use plastic containers to store perishable items in refrigerators. Otherwise, food on an open plate may easily spoil in a matter of hours even when inside a fridge.
For scientific applications, plastic is used to hold sensitive samples of organisms and other specimens that are preserved. For example, petri dishes are made of high quality plastic that maintains optimum conditions inside the enclosing. It is important for scientific plastic containers to be fully transparent. After all, scientists need to directly observe the processes that go on inside petri dishes. Cylindrical shapes are very common for petri dishes that are stored in lab settings. Rectangular shaped plastic containers are used for various biological studies such as observing the growth of plants in a controlled setting.
Professional quality plastic cases are also used by museums and educational facilities that display artifacts and living things. For example, small amphibians and reptiles may be contained in medium size plastic enclosing that's climate controlled with heat lamps. Extra thick plastic walls insulate any sounds that might disturb sensitive lizards and snakes. Pioneer Plastics is an example of a wholesale clear plastic boxes business. Consumers and professional organizations can get their hands on affordable high quality plastic boxes and containers that are used for an array of applications.
Some plastic boxes may have locks that are installed for security purposes. For example, an expensive artifact may be secured at museums and schools that display precious stones and other historic items that are very expensive.
