The difference and use of various types of plastic bottles
Material Name: PET (polyethylene terephthalate) Product use: pure water, mineral water, carbonated beverage bottles. Use characteristics: can not be filled with hot water. Heat resistant to 70 ° C. Can only be used once. Hazard Analysis: Containing high temperature liquid or heating the bottle body will deform and melt out harmful substances. After 10 months of continuous use, carcinogens may be released and are toxic to humans. Must be discarded after use, not used as a water cup, or as a storage container for liquids such as acidic solutions or greases.
Material Name: HDPE (High Density Polyethylene) Product Use: Containers for cleaning products, bath products and supermarket bags. Use characteristics: heat resistance to 110 ° C. Non-food substances can be reused. Hazard analysis: When indicating the food, the plastic bag should not be in direct contact with the food to prevent microbial contamination. The cleaning products and bath products can be cleaned and reused. If the residual liquid is not completely removed, it will become bacteria. The hotbed, it is recommended not to recycle it multiple times.
Material Name: PVC (polyvinyl chloride) product use: and less for food packaging. Use characteristics: prohibit high temperature and grease when packaging food. Do not use it by heat. Hazard analysis: Reasons for toxic and hazardous substances: 1. Single-molecular-weight vinyl chloride that is not fully polymerized during production; 2. Hazardous in plasticizers. When the above substances are exposed to high temperature and oil, they are easily precipitated. If they are injected into the human body, they may cause cancer. It is recommended not to be used for food.
Material name: LDPE (low density polyethylene) Product use: plastic wrap, plastic film use characteristics: heat resistance is not strong, hot melt phenomenon occurs at 110 °C. Hazard Analysis: A plastic preparation that cannot be broken down by the body due to hot melt. Wrap the food with plastic wrap, and the oil in the food can easily dissolve the harmful substances in the film material. Therefore, before the food is placed in the microwave oven, the plastic wrap that wraps the food must be removed before heat treatment.
Material Name: PP (Polypropylene) Product Use: Microwave lunch box, juice drink bottle, mouth cup Use characteristics: resistant to 130 ° C high temperature, poor transparency, can be reused. Hazard Analysis: It is the only plastic container that can be placed in a microwave oven to hold food. It can be reused after cleaning. Special reminder: some microwave oven lunch boxes are made of 05PP, but the cover is made of 06PS which is not resistant to high temperature. It can never be put into the microwave oven to warm food together with the box.
Material Name: PS (Polystyrene) Product Use: Bowled instant noodles box, foamed snack box Use characteristics: heat and cold, but can not be placed in the microwave to heat food. Hazard analysis: If the temperature is too high, it will release chemicals, and it can not contain strong acid (such as orange juice) and strong alkaline substances, because it will decompose polystyrene which is not good for human body. Therefore, try to avoid using hot food boxes to pack hot food.
Material Name: PC (Polycarbonate) and other products Uses: Bottles, cups, barrels, drinking buckets Features: Reusable, but avoid damage or aging container hazard analysis: due to the small amount of bisphenol A in the production PC When the product is not completely converted to the plastic structure of the PC, it may be released into the food or drink. The residual bisphenol A is accelerated and released as the temperature increases. Therefore, hot water cannot be used. If the container is damaged, it must be stopped to prevent bacterial contamination.
