Food safety is a concept that covers a wide range, including the safety of the food itself (such as raw materials and auxiliary materials, additives, etc.), the safety of the food production field (such as the sanitary conditions in the production and processing fields), the health of the operators, and the health and safety of the supporting production equipment, etc.), The safety of the circulation field (such as the storage and transportation of food) and the safety of food packaging materials are some important factors. If the packaging material is not safe, it is difficult to say that the food is safe.

从包装材料的性的角度来看，包装材料的卫生不能达到标准。材料中有害物质的迁移将影响食品并导致食品不。随着转换技术的发展，新的包装技术也给食品带来了挑战，因此食品包装材料的性也应得到认可。具体来说，塑料包装材料的卫生和有几个基本要求：

From the perspective of the safety of packaging materials, the hygiene of packaging materials cannot meet the standard. The migration of harmful substances in materials will affect food and lead to food insecurity. With the development of conversion technology, new packaging technology has also brought challenges to food safety, so the safety of food packaging materials should also be recognized. Specifically, there are several basic requirements for the health and safety of plastic packaging materials:

1.塑料用基础树脂

1. Basic resin for plastics

食品包装中使用的塑料基质树脂是一种高分子材料。如果是纯塑料聚合物材料，它将不会被人体吸收并产生毒性作用。但是，如果在塑料中发现一些有毒有害的“杂质”，则单体或低分子量将保留在塑料中，并且其相对分子量相对较小，或多或少有毒。这些小分子单体在使用时会迁移到食物中，沉积在体内并在一定程度上积累，这会对人体造成不良影响，即毒性作用。通常，如果单体不纯并且对人体有害的催化剂超过标准，则树脂将转化为“有毒有害物质”，这可能导致塑料包装材料的良好健康和性丧失。因此，在GB 4806系列标准和各国有关法律法规中，规定了每种材料中单体的大残留量，生产企业的使用符合GB 4806.6-2016《食品标准塑料》的要求。用于食品接触的树脂”，以塑料包装原料的风险。

The plastic matrix resin used in food packaging is a kind of polymer material. If it is a pure plastic polymer material, it will not be absorbed by the human body and produce toxic effects. However, if some toxic and harmful "impurities" are found in the plastic, the monomer or low molecular weight will remain in the plastic, and its relative molecular weight is relatively small, more or less toxic. These small molecular monomers will migrate to food when used, deposit in the body and accumulate to a certain extent, which will cause adverse effects on human body, namely toxic effects. Generally, if the monomer is impure and the catalyst harmful to human body exceeds the standard, the resin will be converted into "toxic and harmful substances", which may lead to the loss of good health and safety of plastic packaging materials. Therefore, in the GB 4806 series of national standards and relevant national laws and regulations, the large residual amount of monomer in each material is specified, and the use of the production enterprise conforms to the requirements of GB 4806.6-2016 National Food Safety Standard Plastics. Resin used for food contact "to eliminate the risk of plastic packaging materials.

2.塑料添加剂（添加剂）

2. Plastic additives (additives)

通常，我们使用的塑料包装材料通常包含基于聚合物树脂的复合材料。除聚合物树脂外，还有许多添加剂，也称为添加剂。如果添加剂是有毒有害物质，并且其含量超过塑料产品卫生标准的允许值，则该塑料是不适合与食品接触的“有毒有害”塑料产品。

Generally, the plastic packaging materials we use usually include composite materials based on polymer resin. In addition to polymer resin, there are many additives, also known as additives. If the additive is a toxic and harmful substance and its content exceeds the allowable value of the hygienic standard for plastic products, the plastic is not suitable for contact with food as a "toxic and harmful" plastic product.

有增塑剂，抗氧化剂，稳定剂，润滑剂，抗静电剂等。这些添加剂可能迁移到食品中并可能影响食品。

There are plasticizers, antioxidants, stabilizers, lubricants, antistatic agents, etc. These additives may migrate into food and may affect food safety.

如：增塑剂：一般也称为增塑剂。增塑剂是一种工业上广泛使用的高分子材料添加剂。在塑料加工中添加此类材料可以改变塑料加工过程中的柔韧性并增强其流动性，并且使其加工更加容易。增塑剂产品有100多种，但常用的化合物是邻苯二甲酸酯（或邻苯二甲酸酯，也称为取代酯）。但是，这些增塑剂被认为是有毒的，不适合用于食品包装材料。用于食品的塑料包装材料可以替代低毒性的增塑剂。

For example, plasticizer: also known as plasticizer. Plasticizer is a polymer material additive widely used in industry. Adding such materials in plastic processing can change the flexibility and enhance the fluidity of plastic processing, and make it easier to process. There are more than 100 kinds of plasticizer products, but the common compound is phthalate (or phthalate, also known as substituted ester). However, these plasticizers are considered toxic and are not suitable for food packaging materials. Plastic packaging materials used for food can replace plasticizers with low toxicity.
