Is the food packaging material safe? Is it a food-grade packaging bag? According to whether the food packaged inside is a heat-sensitive or photosensitive material, whether the packaging bag is heat-resistant and light-resistant, etc., these problems are very concerned by consumers. Is it safe to explore food packaging materials with these papers?

1. Can food packaging ensure food safety?

Food packaging has two functions. First, to ensure food safety, food packaging can not only ensure food is not contaminated by the outside world; second, to improve product quality, good packaging can also extend the shelf life of food. In terms of food safety, packaging materials can be recognized from two aspects, one is the safety of packaged food. A good material can guarantee that it will not be polluted by outside air and environmental pollution factors; in addition, the shelf life of the food can be extended by good packaging.

2, most of the gifts are overpacked

In order to pursue the high-end and gorgeous effect of food gift boxes, some manufacturers are not focusing on food quality, but aiming at food packaging materials. The truth of the matter is that the inconspicuous transparent packaging comes from qualified plastic raw materials, and the gold and silver packaging is made of recycled plastic and gold and silver powder. These recycled plastic sources are complicated, and some even come from medical waste, pesticide bottles, etc. It is easy to contain a lot of toxic substances and heavy metals. In contrast, good quality plastics cost more than 10,000 yuan per ton, while recycled plastics sell for only four or five thousand yuan per ton, and how big the profits can be imagined.

3, the packaging is too beautiful may contain "poison"

In addition to paying attention to the safety of the food itself, consumers should not be underestimated in the packaging of food. For example, children's food packaging comes with some cards and plastic toys, which are directly in contact with food. The food contains moisture and oil. In contact with food packaging, harmful heavy metals, aromatic amines, benzene, etc. are poisoned by dissolution and osmosis. The precipitation of matter and adhesion to food causes people to eat food contaminated with toxic substances and endanger their health.
