Polybag Factory Teach You How to Choose A Good Polybag
As the concept of low-carbon environmental protection becomes the main theme of society, many fields are practicing low-carbon environmental protection, and so is the packaging material field. Rigid plastic packaging (waterproof bag) is loved by consumers and packaging manufacturers. Keeping up with the low-carbon theme, we have worked hard on packaging plastic materials, and degraded packaging came into being. In order to treat the pollution caused by plastic wastes to the ecological environment, degradable plastics have emerged at the historic moment and become a hot spot of research and development worldwide.
The plastic bag is made of polyethylene, which is what we often call plastic. These materials are non-toxic and tasteless, and will not cause any damage to the human body. But some unscrupulous businessmen are greedy for small profits, using polyvinyl chloride as the material for making plastic bags. Prolonged exposure to this material can affect your health. Now, the polybag factory will tell you how to choose a good quality polybag:
How to choose a good quality polybag?
1. Judging by sound. Shake the polybag firmly with your hands. If the adhesive bag makes a crisp sound, it is of better quality. Conversely, if the sound is very dull, consumers should be cautious when using it.
2. Judging by appearance. After you buy the plastic bag, you can touch its surface with your hand. If it is smooth and delicate, it means that the quality is good.
3. Burning method. Good quality plastic bags are very flammable and emit a paraffin smell when burned. Poor quality plastic bags are not easy to burn, and also give off an unpleasant smell.
4. Prepare a pot of water, then put the plastic bag in the water, press it to the bottom of the pot with your hand, and release your hand after 1 minute. If the plastic bag can float on the water, it is non-toxic. If it sinks to the bottom, it is poisonous and cannot be used.
In addition to affecting physical health, poor quality polybags are also easily damaged during transportation, so everyone must be careful when choosing.
