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).

It should be noted that conventional plastic injection machines are used to produce disposable forks & spoons & knives and thick disposable containers such as trays, dessert and ice cream containers and so forth. The only difference is the changeability of molds by which the containers can be produced in different models and cavities (number of products in each press) in accordance with customers’ order.

Polypropylene (PP) is the main consuming material of forming machines. These machines are composed of two parts: sheet making and pressing (containers production). Therefore, in addition to selling the final product of these machines, the produced sheets could be used in different industries. Since propylene is flexible and is not harmful to human body, disposable glasses are currently made by thermo-forming machines.

Polyethylene terephthalate (PET) bottles for the packaging of beverages with the main purpose of health, health, safety and commerce have increased the use of these bottles to avoid the purchase of products exposed to sunlight and do not Do not reuse these bottle types; In addition, they should not store sour items such as lemon juice, water juice and vinegar in this type of bottle for a long time, and refrain from freezing water inside these bottles.

The automatic vacuum forming machine is a new type of thermoforming unit that integrates and cuts. This fully automatic vacuum forming machine is used in the fully automatic PS foamed lunch box production line. The semi-automatic vacuum forming machine does not have the function of cutting. The automatic vacuum forming machine adopts the man-machine interface computer touch screen control system, which is easy to operate. It has the characteristics of large forming area, convenient cutting and fast forming speed. The equipment can be used to produce a wide variety of shaped sheets. The shape of the finished product can be achieved by changing the mold.
