With the development of the material industry, many types of packaging products have also been produced in the packaging production industry in combination with different material properties. In order to simplify the production description, people often use specific signs in the use of raw materials.

 

PETE
Mineral water bottles and carbonated beverage bottles are made of this material. This material is only suitable for warm drinks or frozen drinks. It is easily deformed when it is filled with high-temperature liquid or heated, and it will produce substances that are harmful to the human body. Scientists have found that after 10 months of use, this plastic product may release carcinogens, which are toxic to the human body. Therefore, drink bottles should be discarded when they are used up. Do not use them as water glasses or storage containers. .

 

HDPE (High Density Polyethylene)
Most of the plastic containers for cleaning supplies, bath products and plastic bags that were previously used for free are made of this material and can withstand high temperatures of 110°C. Plastic containers with this logo can be reused after careful cleaning, but these containers are usually not easy to clean and can easily become a hotbed of bacteria, do not recycle.

 

PVC (polyvinyl chloride)
The harmful substances easily produced by plastic products of this material mainly come from two aspects, one is the single molecule vinyl chloride that has not been completely polymerized in the production process, and the other is the harmful substances in the plasticizer. These two substances are easily precipitated when they encounter high temperatures and fats, and toxic substances easily cause cancer after entering the human body with food.

LDPE (low density polyethylene)
Plastic wrap, plastic film, etc. are all such materials. The heat resistance is not strong. Generally, qualified plastic wrap will show hot melting when the temperature exceeds 110°C, leaving some plastic preparations that the human body cannot decompose. And when the food is wrapped with plastic wrap, the fat in the food can easily dissolve the harmful substances in the plastic wrap.

 

PP (polypropylene)
Microwave meal boxes are made of this material, which can withstand a high temperature of 130° and poor transparency. This is a plastic box that can be placed in a microwave oven and can be reused after careful cleaning. It is important to note that some microwave lunch boxes have a box body made of No. 05, but the lid is made of No. 06 PS (Polyethylene). PS has good transparency, but it is not resistant to high temperatures, so it cannot be put together with the box body. Microwave oven.

 

PS (Polyethylene)
This is a material used for making bowls and foaming fast food boxes. This kind of basin is heat and cold resistant, but it cannot be placed in a microwave oven to avoid the release of harmful chemicals due to excessive temperature, so avoid packaging with fast food boxes Hot food.

 

OTHER (other categories)
It is mostly used for making bottles, kettles, space cups, etc. If your kettle is marked as 07, do not heat it or use it in direct sunlight. In addition, do not use the dishwasher or dishwasher to clean the kettle. When using it, wash it with baking soda and warm water, and dry it naturally at room temperature. If the container has any injuries or breakage, it is recommended to stop using it, because the surface of plastic products has tiny pits, which is easy to hide bacteria.
