Materials <br> Plastic bottles are mainly made of materials such as polyethylene or polypropylene and added with various organic solvents. Most beverage bottles are plastic products. Polyethylene and polypropylene are non-toxic and odorless. It is safe for the human body to fill beverages. However, once polyethylene is dissolved by high temperature or acid, it will slowly dissolve and release organic solvents, which will cause harm to the human body.
Reports have pointed out that long-term consumption of foods contaminated with polyethylene molecules can cause dizziness, headaches, nausea, loss of appetite, memory loss, and even anemia. Therefore, using plastic bottles of vinegar, there are no harm to human health. Therefore, glassware should be used in the home instead of plastic products to contain seasonings. Special attention should be paid when using plastic products. Do not touch vinegar, detergent, etc., avoid direct sunlight, high temperature, etc. to avoid chemical reactions. In addition, when purchasing plastic tableware, you should choose plastic products with PE (polyethylene) or PP (polypropylene) marks, decorative patterns, colorless, odorless, smooth surface.
There are many ways to manufacture polyethylene, the most common of which is the polymerization of ethylene at high temperatures of 200-300°C and pressures of 1,000-2,000 atmospheres. In polyethylene, it is not doped with other substances. The polyethylene thus obtained has a low density and a soft texture, and has a high stability to sunlight, air, moisture, and chemical reagents. Therefore, it is not necessary to add stabilizers and plasticizers, and most of the stabilizers and plasticizers are Poisonous or highly toxic.
Features Plastic bottles easy to carry, not afraid of falling, convenient production, good recovery.
Vigilance at the bottom of the plastic bottle <br><br><br><br><br><br> PET at the bottom of the bottle: mineral water bottle, carbonated beverage bottle, etc. ★ Beverage bottle should be recycled and used hot water <br> Use: heat-resistant to 70°C, only suitable for warm drinks or frozen Drink, install high-temperature liquid, or heat it is easy to deform, there are substances harmful to human body melted. Moreover, scientists have discovered that after 10 months of use, plastic No. 1 may release the carcinogen DEHP, which is toxic to the testis.
Therefore, drink bottles, etc., should be discarded after they are used up. Do not use them as drinking glasses, or use them as storage containers to carry other items, so as not to cause health problems.
"2nd" HDPE: cleaning products, bath products ★ not recommended for thorough cleaning
Use: Can be reused after careful cleaning, but these containers are usually not well cleaned, leaving the original cleaning products, become a hotbed of bacteria, you better not to recycle.
“No. 3†PVC: It is rarely used in food packaging. ★ It is better not to buy it. Use: This kind of material is easy to produce harmful substances at high temperature, even during the manufacturing process, it will be released. Toxic substances will enter the human body with food. After that, it may cause breast cancer, newborn birth defects and other diseases. At present, the container for this material is already relatively small for packaging foods. Never use it if it is in use.
"4th" LDPE: cling film, plastic film, etc. ★ cling film does not wrap into the microwave oven on the surface of the food <br> Use: heat resistance is not strong, usually, qualified PE cling film will appear when the temperature exceeds 110 °C The hot melt phenomenon will leave some plastic preparations that cannot be decomposed by the human body. In addition, food wrapped in cling film heats the fat in the food and dissolves the harmful substances in the cling film. Therefore, when the food is in the microwave, it is necessary to remove the wrapped plastic wrap.
"5th" PP: microwave lunch box ★ When the microwave oven, remove the lid <br> Use: The only plastic box that can be placed in the microwave oven, can be reused after careful cleaning. Need special attention, some microwave lunch boxes, boxes are indeed made of No. 5 PP, but the lid is made of No. 1 PE, because the PE can not withstand high temperatures, it can not be put together with the box into the microwave oven. To be on the safe side, remove the lid before placing the container in the microwave oven.

★ Do not use a microwave to cook bowls of instant noodles <br><br><br><br><br><br><br><br><br><br><br> Do not use microwaves to cook bowls of instant noodles . And can not be used to take a strong acid (such as orange juice), a strong alkaline substance, because it will break down the body of polystyrene is not good, easy to cause cancer. Therefore, you should try to avoid packing hot foods with fast food boxes.
