Frequently Asked Questions about Packaging Bags

In today's society, Internet users have many misunderstandings about the safety and environmental protection of plastic packaging bags. Here, Zhitu plastic packaging bag manufacturer will help you solve your doubts step by step.

1. With “plastic restrictions” and “plastic bans” in place, why are we still using a lot of plastic bags?

"Plastic restriction" refers to the state's control over the production and use of plastic shopping bags with a thickness of less than 0.025 mm. Plastic shopping bags refer to plastic bags with two handles but no handles, such as clothing bone bags, clothing zipper bags, flat bags, etc. There is no control. "Plastic ban" is an administrative regulation in some provinces banning all plastic bags or banning all plastic shopping bags.

"Plastic restriction" does not apply to all plastic packaging bags. So far, plastic is still a material that has a wide range of applications in daily life, has good performance, is convenient, energy-saving and environmentally friendly, and plastic products will only be used more and more widely.

As for the reasons for the "plastic restriction", Document No. 72 of the General Office of the National Academy of Sciences made it very clear and objective: "While plastic shopping bags provide convenience to consumers, they have also caused excessive use and inadequate recycling and processing. Serious energy waste and environmental pollution. In particular, ultra-thin plastic packaging bags are easily damaged and are mostly discarded at will, becoming the main source of 'white pollution'." In fact, talent is the main cause of white pollution.

2. A large amount of plasticizer is added to plastic packaging bags. Use as little plastic as possible?

This is a serious misunderstanding. Among commonly used plastic packaging, only PVC clothing plastic bags need to add plasticizer, and most plastic packaging raw materials do not contain it.

3. Are plasticizers toxic? Can it cause cancer?

Answer: There are many types of plasticizers, which cannot be generalized. Some are toxic, some are harmless, some are carcinogenic, and some are not. Those that are toxic and carcinogenic have very different degrees of harm to humans.

From a toxicological point of view, whether a foreign compound can cause toxicity or carcinogenicity to humans generally requires at least three conditions to be met at the same time, and one of them is indispensable. First, it must have a sufficient dose. Insufficient dosage will not be established; second, it must be foreign. What form the compound is in and the physical and chemical properties of this form. Many substances are harmful in one form and harmless in another form. The third is the way in which foreign compounds come into contact with people, whether they are in contact with the skin, inhaled, or eaten into the stomach. , and absorption status, etc.

Therefore, if someone says that a certain foreign compound is toxic or carcinogenic on some occasion, and he can also tell the relevant situation of the above three conditions, then maybe what he said is possible, and we can go deeper and ask for advice until we agree. If the three conditions are unclear, don’t believe it for the time being but clarify them first.

Because scientific toxicology is supported by toxicology experiments, not speculation. As for carcinogenicity, which is more complicated than toxicity assessment, it requires rigorously designed population epidemiological surveys to determine. Only long-term and lifelong tests on animals can be recognized as conclusive evidence. These investigations and tests are not easy to conduct, so mutagenicity tests can be conducted first to make preliminary speculations about their carcinogenicity. If mutagenicity tests are not even done, how can we say that a certain plastic under certain conditions is carcinogenic?

For all plastic products used as food packaging and containers, the raw materials and additives they use must be tested to meet the hygienic indicators of relevant national standards. Plastic products that are in close contact with food must be tested to comply with national or industry standards after they are produced in the factory. Standard health indicators. At the same time, factories that produce them must rectify the factory's hardware facilities and software conditions according to the industry's production licensing details, conduct product sampling inspections, pass the review by the quality inspection department, and obtain a food production license before they can stamp QS on food plastic products. logo. Moreover, these companies and products must often undergo supervision and inspection by quality inspection departments. Plastic clothing and plastic bag products with QS logo from regular manufacturers can be used with confidence.
