Plastic tableware can be divided into the following categories:
Commonly used as mineral water bottles, cola beverage bottles, juice bottles, etc. Because it can only be heat-resistant to 120°C, it is only suitable for cold drinks and warm drinks. If it is filled with high-temperature liquid or heated, it will deform.
2. High-density polyethylene (HDPE), suitable for food and medicine bottles, cleaning supplies and bath products, shopping bags, and trash cans.
3. Polyvinyl chloride (PVC), which is polymerized from vinyl chloride. High temperature and contact with grease polyvinyl chloride plastics easily release phthalates and incompletely polymerized toxic vinyl chloride monomers. The plastic wrap made of polyvinyl chloride has good transparency, is not easy to break, has strong adhesion and low price. According to its characteristics, it is only suitable for the refrigeration and preservation of vegetables and fruits. It is not suitable for meat, cakes and other foods containing more fat, and it is not suitable for microwave heating.
4. Low-density polyethylene (LDPE) plastic film and cling film have good water barrier properties, so paper-made milk boxes, beverage boxes and other packaging boxes use it as the inner film. Because the low-density polyethylene plastic wrap will melt when it exceeds 120℃, if the food is wrapped with the plastic wrap and heated, the oil in the food will melt some components in the plastic wrap. Remove the film, at least not allow the food to come into direct contact with the plastic wrap. Low-density polyethylene itself does not have degradation properties, and the current "plastic restriction order" mainly restricts it.
5. Polypropylene (PP), which is polymerized from propylene, has better transparency than polyethylene and is harder than polyethylene. Most of the boxes used in restaurants are made of it, and the plastic boxes made can be heated in microwave ovens.
