On the contrary As you might imagine, this color difference is not just for beauty. In fact, in some colors, certain applications have been taken into consideration and the characteristics of colors such as white and black have been used dynamically.
Disposable
Polymers that are used to produce disposable dishes do not have a special color by themselves and after cooling and drying, they mostly turn white or have a transparent appearance. This depends on the type of polymer used, for example, polyethylene terephthalate or PET, as one of the most widely used polymers for making disposable containers, will often be clear, while polystyrene foam is mostly opaque with a white spongy texture. The color is observed.
However, over time, both for creating diversity in products and for unique applications, it has been tried to consider special colors for these products, and as a result of this decision, today with four We are dealing with the main category of colored disposable products:
▪️transparent disposable containers
▪️white disposable containers
▪️black disposable containers
▪️colored disposable containers
Disposable
Transparent containers are made of polyethylene terephthalate (PET) or polystyrene (PS) and they are widely used in the production of containers and containers with different shapes and dimensions. Their use has been proven for cold drinks, desserts and salads, and they are used in fantasy designs to store and supply products such as cakes and sweets, fruits and vegetables, and all kinds of ice cream.
The focus on using these models is more than any other. The focus is on displaying the contents, and for this reason, their ability to provide attractive contents is more important than the technical characteristics of these models.
White
White opaque containers have been widely available for a long time and can be considered the most common color of disposable containers. A variety of hot and cold uses are considered for them in the manufacture of plates, glasses and spoons and forks, although it is generally accepted that these products release harmful monomers when exposed to heat, and therefore their use for hot food Not ideal.
White color is important for these models because it is the best choice for reflecting heat and not absorbing it. The smooth and hard models of these products are made of polypropylene (PP) and polyethylene (PE), while the foamy and flexible models are produced with polystyrene (PS). Polystyrene foam is becoming obsolete over time and is less visible.
Due to their ideal resistance to cold and impact, these containers are ideal for storing food in the refrigerator and freezer, and their prices are lower than all other models. So, it is safe to say that the white disposable container is the cheapest model available in the market.
Disposable Black
These models have become very popular especially in recent years and if you buy food from restaurants, you must have seen them in different designs and sizes. The polyethylene (PE) or polypropylene (PP) used in these models is covered with a thick layer of heat-resistant paint so that they can be used to keep the contents warm. This thick paint layer also helps Monomers do not enter the content directly from the polymer body, and as a result, we are faced with products that are much safer than the transparent and white samples.
The most important customers of black containers are restaurants, catering and public transport companies such as railways and airlines. Offices, factories and workshops that provide food for their workforce and value their health often go for these products. Meanwhile, these products have met with great success for serving food in trains and airplanes. So the black color is used here to maintain the temperature and prevent the contents from being contaminated.
Disposable container
Some examples of these products are available in fancy colors and semi-transparent. Seeing colors such as red, pink, blue, green and yellow among these products is not so strange, and many times depending on the application, you may encounter a change in the design.
The material of these products can be polypropylene (PP). , polyethylene (PE) and, of course, in some cases, paper, and they are mostly used for celebrations, parties, and picnics. Perhaps, their most important use can be considered as birthday parties, which makes the colorful and happy appearance of these products an attractive option for children and teenagers.
