Recently, the news that plastic products cause harm to the human body has been upright. After the melamine tableware, the safety of plastic products has risen again. US researchers found that certain types of phthalates contained in plastic products may inhibit the hormones in male fetuses, leading to the feminization of boys. And more and more science shows that some chemical substances in plastic bags have chronic toxicity. Long-term exposure will not only harm people today, but also affect future generations. This undoubtedly has been widely used in modern life since its inception. Plastic products that are popular among people and benefit humanity have been jeopardized.
Plastics is a polymer material made of a macromolecular polymer resin as a basic ingredient, and then added with various additives to improve its performance. Plastic products in the manufacturing process to add stabilizers, plasticizers, colorants and other additives exceeding the standard when there is a certain degree of toxicity. Food packaging commonly used plastics PE (polyethylene), PP (polypropylene) and PET (polyester), because the use of additives in the processing process is less, the resin itself is relatively stable, their safety is very high. In fact, safe and reliable plastic products are basically harmless to the human body. Experts also remind consumers to purchase meal plastic products. If there is no QS mark, they cannot be purchased. These products without quality assurance are likely to bring health problems to consumers. The following is just a summary of the means to identify the safety of plastic products together with Xiaobian!
Safety identification of plastic bags and food packaging bags
When purchasing plastic bags and plastic packaging, the safety of food plastic products can be identified by means of sight, smell, questioning, and cutting. Look, first pay attention to the name of the product, in order to identify its use and scope of use, can not be used indiscriminately, so as not to cause accidents; followed by the presence of QS mark on the label of goods, which is the national standard of food contact plastic products certification, observation At the time of the product, passable products will never exhibit poor light transmittance or problems such as spots, aerosols, or bubbles. Smell, if there is a strong plastic taste, it proves that the container is not suitable for food preservation, it may also be failing or inferior products, plastic products for foodstuffs that pass quality should not have any odor. Q. If the main role is to load food, special attention should be paid to the sales staff to understand whether the use of plastic products can be used for food preservation. Finally cut it and carefully touch the plastic container. If a burr occurs at the plastic opening, it is a failing product.
Some individual processing households reduce costs for the sake of coveting interests. The used oil drums, jugs and even infusion pipes, pesticide cans, etc. are all treated as raw materials for plastic food bags, and tons of harmful recycled plastic food bags are continuously flowing into various places. The market brings health risks to consumers. Experts believe that due to the fact that many recycled plastic food bags have already entered the market, and illegal production and sales in some areas still exist, people should be reminded to strengthen their identification. There are three reference methods: First, put plastic bags into water. If they sink into water, it is Recycled materials do, if floating on the water, is the new material to do; Second, the plastic bag made of recycled material has an unpleasant odor, the new material to do the plastic bag smell is weak or no odor; Third, renewable materials do The toughness of plastic bags is poor, and the toughness of plastic bags made from new materials is relatively good.
In daily life, it is common for every family to use plastic bags, plastic containers, and other foods that are packed in plastic containers. As we all know, plastics used to package and hold food should be non-toxic. But sometimes people do not pay attention to this issue and readily pick up a plastic bag and use it to hold food. They do not know that doing so is harmful to the body. Because these plastic bags are added with the plasticizer dibutyl phthalate and dioctyl phthalate during the manufacturing process, they are toxic, and the added stabilizer, lead stearate, is also toxic. In addition, lead and salt are easily precipitated, and once they enter the human body, they will have a collection function. For a long time, they cause poisoning. Therefore, special food bags and boxes must be used for packaging and serving foods in plastic products. They must not be used indiscriminately.
Safety Identification of Plastic Fast Food Boxes and Packaging Films
In order to make people try to avoid the use of substandard products, experts gave tips for identifying inferior products: fast food boxes: In general, qualified products have good finish and brightness, and they have a certain degree of strength when squeezed. It smells no smell.
The poor quality Lunch Box, soft to the touch, has no elasticity, and tears when it breaks lightly, smelling a pungent smell. In addition to the above methods of identification, submerged experiments can also be used to verify the pros and cons of fast food boxes: Inferior products generally include cheaper minerals such as calcium carbonate, talcum powder, with a higher specific gravity than water, and the snack box is broken into water. Stirring, sinking is unqualified, while the proportion of qualified fast food boxes will be on the surface.
