Changzhou Plastic Bags How to identify the quality?
Changzhou Plastic Bag Manufacturers: When it comes to plastic bags, we are all familiar with them. We encounter them frequently in both our daily lives and work. Among the many types of plastic bags, they are widely used primarily due to their excellent sealing properties, good freshness preservation when packaging various products, high transparency, and enhanced aesthetics. Therefore, their application is currently quite extensive in my life and work. They can be made into various types, but different types of packaging bags look very different. Many people don't know how to distinguish the quality of plastic bags. So, what are some good identification methods?
Actually, you can identify them through smell, sight, and touch, which can help you find better quality packaging bags. Smell is obtained through the sense of smell. Some plastic bags have a pungent odor, and generally, it's not recommended to choose them; some are even toxic and harmful to the body with long-term use. Visual inspection involves observing the plastic bag's color to see if it's pure, checking the thickness, and observing whether the color is uniform. This can help identify the quality of the packaging bag. In terms of feel, you can touch the packaging bag; generally, it should be smooth and soft. Those that are very thin and light are generally not recommended.
Changzhou Plastic Bag Manufacturers: If you are still trying to buy plastic bags, try the above methods. Through personal experience and feeling, you can effectively identify the quality of plastic bags.
Changzhou Plastic Bag Manufacturers: Precautions for Choosing Plastic Bags
As a type of plastic packaging bag, special attention should be paid during selection. Industry experts believe that plastic food packaging bags can be used in a concentrated manner, but colored plastic bags should not be used to hold food. It is introduced that plastics include polyethylene, polypropylene, polyester, polystyrene, etc. Currently used in food packaging, they are qualified with hygienic functions and are safe food packaging. However, customers cannot distinguish between food and non-food plastic bags, so some unqualified plastic bags are used for food packaging, seriously harming people's health.
Changzhou plastic bag experts specially remind that when packaging cooked food, snacks, and other direct food items, plastic bags should not be used because the dyes used in plastic bags have strong permeability and volatility. When they encounter oil or heat, they simply seep out. Even if they are organic dyes, they will contain aromatic hydrocarbons, which have a certain impact on health. In addition, many colored plastic bags are made from recycled plastics. Because there are many impurities in recycled plastics, manufacturers have to add pigments to cover them up.
Changzhou Plastic Bag Manufacturers: However, some plastic bags made from recycled plastics are also white. Experts also point out that there is currently no particularly useful method to distinguish between plastic food bags. But one thing is certain: plastic bags produced by irregular manufacturers and sold at street stalls should not be used for food packaging. In addition, plastic bags with a peculiar smell should not be used to hold food.
The above is a detailed explanation of "How to identify the quality of Changzhou plastic bags?" Have you all understood? I hope the above explanation can help everyone. Thank you all for watching, and see you next time.
