What does food grade safe plastic material have?

Food processing industry is one of the most widely used industries of plastic products, because food is the material closest to people's life and food is very rich in variety and range, so food-grade plastic products are widely used, mainly in the outer packaging of food. Yuhuan Qianhuan Plastic Industry Co., Ltd. Engaged in plastic packaging for many years, has rich practical production experience, has a deep understanding of food grade safe plastic material processing, the following is to explain how to distinguish food grade safe plastic material.

PET
1.PET plastic is often used to make plastic bottles, beverage bottles and other products. The plastic mineral water bottles and carbonated beverage bottles that people often buy are PET packaging products, which belong to food grade safe plastic material.
2. Safety risks: PET is only suitable for room temperature or cold drinks, not for overheated food. If the temperature is overheated, the bottle will release toxic substances that may lead to cancer. If the PET bottle is used for a long time, it will automatically release toxic substances, so the plastic beverage bottle is immediately discarded after use, do not use for a long time to hold other food, so as not to affect health.
PP
1 PP plastic is one of the most common plastic, can be made into any food plastic packaging, such as food plastic bags, food plastic boxes, food straw, food plastic parts, etc., safe and non-toxic and low temperature resistance, high temperature resistance, PP is the only can be put into the microwave heating plastic.
HDPE
1.HDPE plastic, commonly known as high-density polyethylene, has a high temperature, hardness, mechanical strength and good chemical resistance. It is a non-toxic and safe material, which is often used in the production of plastic containers for food, vest bags, supermarket shopping bags, convenience bags and clothing bags.
2, safety risks: PLASTIC containers made by HDPE are not easy to clean, so it is not recommended to recycle. It's best not to put it in the microwave,
LDPE
1.LDPE plastic is commonly known as low density polyethylene, and the products made of it have the characteristics of tasteless, odorless, non-toxic and dull appearance. Commonly used in food plastic parts, food packaging with composite film, food cling film, medicine, medicine plastic packaging and high-grade industrial products such as ziplocks.
2 safety risks: LDPE heat resistance is not strong, usually more than 110℃ will appear hot melt phenomenon. Such as: household food cling film do not wrap food heating, to prevent the oil in the food will be easy to dissolve the harmful substances in the cling film.
PS
1.PS is often used to make bowl loaded instant noodle boxes, fast food boxes, disposable food packaging boxes, etc., with good cold resistance.
2. Safety risks: PS can not be put into the microwave oven, so as not to release toxic substances over high temperature. Poor acid and alkali resistance, not suitable for bearing acid food, prevent decomposition.
PC
1.PC plastic can be used to make sports cups, kettles, bottles, etc., widely used in the production of plastic containers, is a safe material.
2. Safety hazards: residual BISphenol A (harmful substances) in PC, the higher the temperature, the more release, the faster the speed. Therefore, do not use PC water bottles to hold hot water, so as not to increase the release rate and concentration of double pan A (if any).
PVC
1.PVC: it is widely used in packing boxes, PVC transparent cylinder export packaging, tinplate PVC transparent handle cans, toy packaging and food packaging boxes.
2. Safety risks: this material is easy to dissolve and release at high temperature, and should not be baked at high temperature.
BOPP
1.BOPP: high transparency, strong tensile resistance, not easy to deform, mainly used for printing food packaging, tea bags, clothing packaging, product packaging.
CPP
CPP: divided into high temperature and low temperature, high transparency, strong tensile strength, not easy to deform, mainly used for printing food packaging, tea bags, clothing packaging, product packaging.
