Ordinary food plastic packaging products are mainly made of synthetic resin as the main raw material, adding appropriate amount of plasticizer (I. e. plasticizer), stabilizer, antioxidant and other additives, and processed under certain plasticizing conditions. Henan food packaging commonly used polypropylene (PP), plastic polyethylene (PE), polyester (PET) and polyvinyl chloride (PVC) and so on. Among them, polyethylene (PE), polypropylene (PP) itself is non-toxic, the amount of plasticizer added in the processing process is very small or even basically not added, so polyethylene (PE), polypropylene (PP) is a health, safety better packaging materials.
Here to introduce different materials of food blister packaging products of their respective characteristics and application;
1, PC (polycarbonate) and other categories: used in the manufacture of bottles, space cups, etc. Try not to use it to hold boiled water. It is easy to release the toxic substance bisphenol A. Do not heat it when using it and do not expose it to the sun.
2, HDPE (high density polyethylene): high temperature resistance, but not easy to clean, easy to breed bacteria, do not recycle.
3, PET (polyethylene terephthalate): heat resistant to 70 degrees Celsius and easy to deform, there are harmful substances dissolved. Prolonged use may release the carcinogen DEHP. Can not be placed in the car in the sun, do not hold wine, oil and other substances.
4. LDPE (low density polyethylene): used for plastic film, plastic film, etc. High temperature will produce harmful substances, so do not put plastic wrap in the microwave oven.
PP (polypropylene): the only plastic box that can be put into the microwave oven, which can be reused after careful cleaning.
6. PVC (polyvinyl chloride): raincoats, building materials, plastic films, plastic boxes, etc., are rarely used for food packaging.. 0125X2=0.63 yuan
7. PS (Polystyrene): The material used to make bowl-packed foam noodle boxes and foam snack boxes cannot be heated in microwave ovens, and cannot be used to pack strong acidic (such as orange juice) and strong alkaline substances. Avoid hot food.
