Plastic container descriptions help us make sense of a world that seems to always be changing. The term “plastic container” refers to a number of different items. Container descriptions help us categorize and sort items. This categorization can be as easy as individual usage, generic usage, etc. In other words, the use of this term would depend on which context the item is going to be used.
Basic Description: Plastic is a thermo-transparent, multilayer, thick-urethane material made from polyethylene terephthalate (PET) and other plastics. Plastic containers are generally made of high-density polyethylene, low-density polyethylene, or polypropylene fibers. Plastics are generally defined as thermoplastics, thermosetting plastics, or thermo-adhesive plastics thung nhua to dung nuoc.
Application: Plastics are used in a wide variety of different applications. Container manufacturers, chemical manufactures, cosmetic manufacturers, food packaging, pharmaceuticals, etc. manufacture plastics for specific purposes. Containers may be required to hold chemicals, liquids, or other products that have the potential for causing harm if not kept in the right temperature, cleanliness, or otherwise. High-throughput screening and other physical properties are used to improve product safety. Containers may also be required to contain flammable gases or highly flammable liquids, in which case, plastic container manufacturers must meet fire safety standards to comply with law.
Phthalates: Phthalates are man-made chemicals that have a wide range of applications. Phthalates are often found in plastic food containers and plastic wrapping. The Environmental Protection Agency (EPA) estimates that nearly two million pounds of phthalates are released into the environment from plastic bottles alone. Some phthalates are emitted when plastic is melted, while some phthalates are released when plastic is processed.
While exposure to phthalates poses little risk to adults, they can cause long-term health effects to children. Children who consume plastic foods and beverages may be at increased risk of developing asthma and other respiratory conditions. Other respiratory problems include bladder and lung cancer. Plastic containers with phthalates have been shown to increase the risk of certain types of cancer in adults and infants. While the majority of chemicals used in plastics pose no immediate threats, their long-term consumption can lead to serious health consequences.
Disposable Food Containers: Food packaging has come a long way since the early days of glass and plastic. Today, plastic containers account for more than 75% of the materials used to package foods. Some plastic packaging goes into making packaging peanuts and other nuts, as well as plastic that go into making non-food packaging. One of the most common uses of plastics in food packaging is polyethylene terephthalate (PET), which is used to create food containers that resist odors and are leach-resistant. Other commonly used plastic materials in food packaging are PVCu and PVCs, also known as polypropylene.
