Plastic is an important choice for packaging of various products. Its safety has been discussed by countless people, but there is still no conclusion. In fact, whether plastic is safe is relative. Only by choosing the right material and choosing the right usage can plastic become safe. 1. There are also differences in the packaging requirements of different materials, so it is necessary to choose the right material. The most important product when it comes to safety is food. Therefore, the packaging materials used for food must be food-grade. According to national regulations, PET (polyethylene terephthalate), HDPE, LDPE, PP, etc. are all food-grade plastics, but these materials have different properties and advantages. For example, the most common PET is not suitable for making water cups or storage containers, PP can be heated in microwave ovens, and so on. Therefore, when food manufacturers choose packaging materials, if they do not know enough about the characteristics of the materials, they must choose a large-scale and reliable production enterprise, and professionals can help determine the packaging materials, which can largely avoid the problems caused by improper material selection. safe question. 2. Use plastic products produced by regular manufacturers. In order to reduce costs and obtain huge profits, many manufacturers in the market use shoddy products. The plastic packaging produced does not inform customers of the scope of application, resulting in safety problems. Therefore, it is recommended to choose packaging bags
and plastic products produced by regular manufacturers, especially food with high liquid and oil content, because oil and high temperature will affect the performance of plastics. 3. Correct use of plastic products Each plastic product has usage standards, and consumers are advised to use it in the correct way. For example, plastic bottles are safe at room temperature, but they will become soft and deformed when heated, so it is not recommended to use such containers to store overheated food. Whether plastic is safe or not can be identified in the following ways. Visual sense: the surface of qualified plastic products is relatively smooth, the color is relatively clear and transparent, and the flexibility is good; the color of unqualified plastic products is relatively turbid. Olfactory senses: Qualified plastic products have no peculiar smell at room temperature; unqualified plastic products smell pungent or unpleasant. Tactile sensory: Qualified plastic products have a smooth touch and good flexibility; unqualified plastic products have a rough touch, poor flexibility, and may be accompanied by odor.
