Packaging barrelVarious plastic products are everywhere in the market, especially food packaging barrels. Consumers know very little about their materials and uses. According to relevant standards, the bottom of the packaging barrel should be marked with a triangular plastic recycling symbol. Although this marking method is not a mandatory requirement, medium and large enterprises usually mark it to facilitate the recycling of plastic products. Therefore, when consumers choose packaging barrels to hold food, they must identify the markings on the bottom.

First,Packaging barrelthe bottom is printed with a triangle made up of three arrows, with a number in the middle ranging from 1 to 7. The triangle indicates that the plastic material is "recyclable," which does not mean it can be reused. Each number from 1 to 7 represents a type of material. If a product is made of several different materials, the marking indicates its primary material. Consumers can use this mark to distinguish the materials, applications, and usage environments of the plastic products they use. Details are as follows:

"1" refers to PET (polyethylene terephthalate). Both mineral water packaging barrels and carbonated beverage packaging barrels are made from this material. They can withstand temperatures of 70°C. When filled with high-temperature liquids or heated, they can easily deform, and harmful substances can dissolve out. Scientists have found that after 10 months of use, this plastic product can release carcinogens that are toxic to the human body.

"2" refers to HDPE (high-density polyethylene), which is commonly used to produce white medicine bottles, cleaning products, and shower products. Currently, most plastic bags used in supermarkets are made from this material, which can withstand high temperatures of 110°C. It has been pointed out that food plastic bags can be used to hold food.Packaging barrelAfter careful cleaning, those containing cleaning products and shower products can be reused, but these packaging barrels are usually difficult to clean, leaving behind the original cleaning products, becoming a breeding ground for bacteria, so do not recycle them.

"3" refers to PVC (polyvinyl chloride), which is commonly used to produce raincoats, building materials, plastic films, plastic boxes, and other products. The toxic and harmful substances that plastic products made from this material can easily produce come from two aspects: one is unpolymerized monomer vinyl chloride that is not fully polymerized during production, and the other is harmful substances in plasticizers. These two substances can easily precipitate when exposed to high temperatures and oil. When toxic substances enter the human body with food, they may lead to cancer. Currently, packaging barrels made from this material are rarely used for food packaging. If you use this food packaging, do not let it be heated.

"4" refers to LDPE (low-density polyethylene), and both plastic films and plastic wraps are made from this material, which has poor heat resistance. Generally speaking, qualified PE plastic films will melt at temperatures exceeding 110°C, leaving behind some plastic products that the human body cannot decompose. Wrapping food with plastic wrap and heating it.
