Plastic shopping bags are the most commonly used plastic bags in people's daily life. However, most people only know that plastic shopping bags are not damaged when they are packed , but it is not clear whether these shopping plastic bags are all qualified products. So how do we know whether plastic shopping bags are qualified?

First, the thickness of plastic shopping bags . The state has stipulated that the thickness of plastic shopping bags in circulation on the market cannot be less than 0.025mm. Most custom plastic shopping bags on the market will also be marked with thickness. Generally speaking, the thickness of plastic shopping bags used in supermarkets basically exceeds national standards. In fact, in order to sell products whose thickness does not meet the standards, some businesses will also do tricks on the thickness scale. However, integrity is an important factor for shopping plastic bag manufacturers. For example, Shanghai Leyi Plastic Products Co., Ltd. adheres to integrity and wins customer trust.

Second, whether the plastic shopping bag ink is toxic. In the process of customizing plastic shopping bags, which ink is chosen during the printing process will also have a great impact on environmental protection. Toxic inks are prone to discoloration after contact with cooking oil. Therefore, before buying a plastic shopping bag with printed words, you can use edible oil to test whether the printing ink is environmentally friendly. Colored plastic bags cannot be used as food plastic bags. This vest bag contains aromatic hydrocarbons and has a carcinogenic effect.

Third, the bearing capacity of plastic shopping bags. At present, the state stipulates that custom-made plastic shopping bags must be labeled with their own bearing capacity, but in the sales market, there are still a large number of plastic bag products that are not marked with bearing capacity. The simplest test method is to use a plastic shopping bag with a certain weight of product, walk with the plastic shopping bag, and see how long the plastic shopping bag can last. This test is troublesome, so why should buyers pay attention to the load bearing capacity of plastic shopping bags? This is because a plastic shopping bag with a poor load bearing capacity often breaks during use, which will increase the number of customers using plastic shopping bags and cause waste.

Fourth, the burning experiment of plastic shopping bags. The raw materials of custom-made plastic shopping bags determine the quality of plastic shopping bags. Bags made of food-grade raw materials are the most environmentally friendly. Waste materials, as well as plastic shopping bags made from waste materials and pigments, are low in cost and have certain toxicity. Ignite the plastic shopping bag and wait for it to extinguish naturally. Observe whether black smoke, pungent odor is generated before and after burning, and whether black matter is left.

These four points are the most basic and most effective way to distinguish whether a plastic shopping bag is qualified. At present, the regular shopping plastic bag manufacturers are strictly produced and strictly inspected, just like Shanghai Leyi Plastic Shopping Bag Manufacturer. So don't worry too much about whether the shopping plastic bags you buy are qualified.
