since the plastic packaging bag was born, it has been deeply loved by people for its light weight, low cost, high strength and other characteristics. people are used to using plastic bags to pack things. there are many kinds of plastic packaging bags on the market, but there are countless kinds from the color. what kind of good? do we really choose plastic bags? although we can use plastic bags almost every day, we often go into the wrong area in choosing plastic bags.

( 1 ) the thicker the plastic packaging bag, the stronger it will be. we often see all kinds of plastic bags in our life, so a strong bag would be good. in fact, this is not the case. plastic bags have strict standards, especially plastic bags used for food packaging. they must be made by regular manufacturers and have qualified products approved by relevant departments, so that the quality of these plastic bags can be guaranteed.

plastic bags for food must be marked with the words " for food". you can see whether the plastic is clean or not by looking at the light. qualified plastic bags are very clean and free of impurities, while inferior plastic bags will see dirty spots and impurities. the thickness of one side of the plastic bag must be above 0.025 mm. if it cannot reach this thickness, the state prohibits its production and use.

( 2 ) plastic packaging is colorful, how beautiful is the choice of color packaging. although there are many kinds of colors in plastic packaging bags, we must be careful when choosing them. if plastic packaging is used for food items, we must choose simple colors only from the color point of view, so that at least there are fewer additives. many dark-colored plastic bags are often made of recycled waste materials. these plastic bags cannot directly contact food.

( 3 ) reuse of plastic packaging bags. many families have the habit of storing waste plastic bags. in fact, it is ok to keep them neat and use waste plastic bags, but do not use waste plastic bags to contact food and skin, which will cause chronic damage to our health.
