In our daily life, plastic packaging bags play a very important role and have many styles. The quality of plastic packaging bags currently circulating on the market is also uneven. When we go shopping, what aspects should we pay attention to? Let's follow the editor to learn about the selection items together?
Introduction to Quality Matters of Plastic Packaging Bags: Packaging bags have strict regulations, especially for food packaging bags. When selecting, it is necessary to select plastic packaging bags produced by legitimate manufacturers with qualified marks. Check the plastic bags in front of the light to see if they are clean. Qualified ones are all clean, and defective ones will show dirt. As long as the single-sided thickness meets the specifications, the thicker the better.
Sound discrimination is determined through "hands". Good plastic packaging bags have flexibility, a sense of lubrication when touched, and a waxy appearance. Poor quality plastic packaging bags have a sticky feeling; After "listening to the sound", grab one end of the plastic bag with your hand and shake it vigorously. It is announced that the quality is better for those with a loud sound, but if the sound is dull, there may be quality issues.
Chemical reaction discrimination is determined by "fire" burning. Plastic packaging bags with good quality are flammable, with the top of the flame being yellow and some parts being cyan. When burned, they drip like candle tears and have a smell of paraffin; Plastic packaging bags with poor quality are not flammable and will extinguish immediately after leaving the fire. The top of the flame is yellow, and the bottom is green. They can soften and wire, and announce the pungent smell of hydrochloric acid.
