In my country, there are strict laws and regulations on food-grade plastics. First, they must meet the FDA food safety certification of ABS plastics. At present, basically few ABS plastic pellet processors in China have passed this strict certification system, and most of them are It is a foreign manufacturer. ABS plastic food contact plastics. First of all, it should be emphasized that food-grade ABS plastic is not edible. It is called food-grade mainly because its materials can directly contact food and are non-toxic. However, plastics without food-grade labels cannot be used. If the food is in direct contact, it will affect the food safety.

Then the food-grade plastics we see daily are mainly made of PE plastics. LDPE plastics and HDPE plastics are both food-grade plastics. LDPE plastics are non-toxic materials with smooth surfaces and film-forming properties. Use food packaging plastic parts, food packaging film, cling film, pharmaceutical packaging, pharmaceutical packaging, etc.

HDPE plastic has many advantages such as high hardness, excellent chemical stability, and strong mechanical strength. It can be used as plastic containers such as food wrap, plastic bottles, and baby bottles. PET plastic is also food-grade plastic. At present, the plastic bottles used by manufacturers for water and beverages are mostly pet and hdpe plastic products, which can also be food packaging boxes, such as cake boxes and fruit boxes.

As a food-grade plastic, I believe everyone knows about PP plastic, because baby bottles are PP plastic products. PP plastic has excellent properties such as safety, non-toxicity, high temperature resistance, and flexibility. It can be used in plastic boxes, plastic tubes, and plastic bags. , Frozen food bags, etc. In the early stage, PS plastic is a commonly used disposable tableware product, which can be used in fast food boxes, instant noodle boxes, milk boxes and so on.

Therefore, it is not to say that abs plastics cannot be used in the food industry. The main reason is that the requirements for food-grade plastics are extremely strict, and production costs and processing control are difficult to master. Secondly, food-grade plastics have very high requirements for raw materials, that is, abs plastic particles. On the whole, the use of PE or HDPE materials is more in line with the needs of this specific industry.
