The food industry uses plastics for many different purposes. For example, reusable containers can be made of polypropylene, which is FDA approved for food contact. This plastic is also resistant to extreme temperatures, making it a great option for microwaves and dishwashers. It is also light and flexible, which is ideal for the hinges of condiment bottle caps.
However, the type of plastic used in a specific application can have an effect on food safety. For example, some are more chemically resistant than others, and some are better for direct contact with food. But the bottom line is that all plastics should be FDA approved food grade. Using a bad quality plastic can lead to a variety of problems. These can include food contamination and even long-term health hazards.
The best plastic for food storage and handling is HDPE food safe plastic. HDPE is also known as high density polyethylene, and it is extremely durable. Food containers made of this material can be recycled, and they are designed to last for years. They are also a popular choice for household food packaging, such as milk jugs. In addition, HDPE is FDA approved.
LDPE is another common plastic for household food packaging, and it is less rigid than HDPE. LDPE can be recycled, and it is also easier to re-use than HDPE. LDPE is also more flexible than HDPE, which makes it a good choice for hinges on condiment bottle caps.
While there are many plastics available, the FDA has very specific rules about which ones are suitable for food use. In particular, plastics that are FDA approved must be free of halogenated compounds and be able to resist moisture and oils. Additionally, they must be safe for human consumption, and be able to handle bodily fluids.
One of the most common types of kitchen products that are made from plastic are bento boxes. These Japanese inventions can be easily placed in the microwave, and they have a cooling gel to help preserve the food. Various materials can be used for these containers, such as polyethylene and ABS. Many are translucent, giving the user a semi-transparent view of the contents.
Other plastics can be made into interesting shapes. Some are highly resistant to chemicals, and some are more resistant to heat and stress. If you need a more durable and resilient material, you might consider polyurethane. Or you can opt for glass.
Although these are some of the more common plastics used in the kitchen, there are others, and knowing them can help you make a safer choice. You might also consider other, more eco-friendly materials such as bamboo, which can grow back in a matter of months. Bamboo can replace a number of kitchen products, and they are also easy to replenish.
There are a variety of other factors that can affect your decision, including the color of the packaging, the texture, and the weight. In general, though, bright, colorful plastics are better for food safety.
