In addition, the insertion of the PS symbol indicates that it is made of polystyrene and such a container is in contact with hot and greasy foods due to the release of styrene carcinogenic monomer; therefore, these containers should not be used for food and hot drinks And fatty acids, and are used only for soft drinks and cold-fat foods. These containers are available in three types of polystyrene foam (EPS), expanded polystyrene (HIPS) and ordinary polystyrene containers (GPPS).

Setting up a single-use container production line with an injection molding machine also provides great versatility regarding the type of plastic chosen. This enables the production of food containers with custom finishes, shapes, fasteners, colors, printing and custom branding. Common plastics or polymers used in the production of food containers include polypropylene, styrene and polyethylene. These have flexible properties, resistance to heat, chemicals and wear and tear, plus excellent hygienic integrity.

During several years of professional experience in marketing and business development consulting, one of our honors was to work with Pars Plastic Khuzestan Company because of the constant emphasis of managers on maintaining quality and not using recycled materials due to consumer health. The supplier gave us a lot of hope that even in these difficult economic conditions, it is possible to find quality and affordable products in the Iranian market. We see a bright future for Pars Plastic, and this is the beginning of a strong presence in international markets.

Generally, all disposable containers are divided in two categories: semi-forming (PS) and thermo-forming (PP). They differ in consuming materials, production stages and price. In all disposable container production machines the raw material melt and then are formed into sheets and get different shapes via pressing and shaping processes. In semi-forming machines, all above-mentioned stages are integrated and the consuming material is polystyrene (PS). These machines generally produce fragile containers. However, these machines produce majority of disposable containers, including bowls, cups, dishes and mushroom container. The reason is the low price of semi-forming machines compared to forming-machines. Since the containers are fragile and harmful, especially in dealing with hot, these machines are not recommended for producing disposable glasses.
