Disposable plastic tablecloth, PEVA printed tablecloth, table cloth poisonous?
The general features of poisonous plastics are:The color is strong and strong because of the addition of large amounts of paint (organic or inorganic). But cheap paint is poisonous.The plastic is impure and may be recycled plastic or doped with other plastics. This plastic is not guaranteed to be safe from its source. Such as medical waste plastics and garbage collection.When the heat becomes soft, the hand feels sticky. The majority of PVC, the softer the plasticizer and the lower molecular weight polymer, the more generally unsafe.Plastic tablecloths do not touch food for long periods and do not touch food at high temperature. Plastic has no peculiar smell, aging plastic is replaced in time, so it is safe.
Engineering plastics are non-toxic, but they are not encountered in life. The cost is very high, often used as structural materials, such as mechanical parts and precision parts.The plasticizer problem in Taiwan was due to the addition of DEHP to the food. DEHP normal use is used in plastic processing. It is safe to use normally.
PVC process adds lead containing heat stabilizerPC has long been used in hot environments to release bisphenol A, and the European Union is suspected of causing precocious puberty.PE, PP, and PET additives use less additives, but they are not recommended for long-term use in thermal environments. (such as disposable plastic cups, mineral water bottles, barreled buckets).
Plastic is non-toxic, because plastics are large molecules, the body can not absorb. Only when the additives needed to be processed are poisonous or are not reacted at the time of synthesis, the small molecules are released in use, and the plastics show toxicity.
