Disposable plastic tableware purchase suggestions

Disposable plastic tableware refers to utensils intended for dining or similar purposes which are processed by thermoplastic molding of resin or other thermoplastic materials. The products are inexpensive, are frequently used in daily life, can be seen everywhere, and the dosage is relatively large. The lives of the people are closely related, and the quality of their products will also affect human health and daily life.

According to the provisions of GB18006.1-2009 "General technical requirements for plastic disposable plastic tableware", the sanitary physicochemical indicators of disposable plastic tableware mainly detect evaporation residue, heavy metal, decolorization test and other items, and the physical properties mainly include temperature resistance and load-bearing performance. project. The quality and safety issues mainly focus on the use of recycled materials and non-food grade chemical raw materials, excessive addition of additives, resulting in heavy metals and evaporation residues exceeding the standard. Long-term use can cause adverse reactions in the human body, such as stones and other diseases, endangering human health. In addition, in order to save costs, the thickness of disposable tableware is reduced, resulting in unqualified load-bearing performance. It is difficult for consumers to hold it during use. If it is very hot, it is easy to burn.

At present, the common disposable plastic tableware in the market mainly includes: plastic lunch boxes, disposable straws, plastic knives, forks, spoons, crisper boxes, plastic cutting boards and plastic stir bars. According to the materials used in the production, there are mainly PET (polyethylene terephthalate) PE (polyethylene), PP (polypropylene), and PS (polystyrene). The four materials are non-toxic, odorless and tasteless. Generally, the bottom of the disposable plastic tableware will be printed with a recycling mark, and each number indicates the material of a plastic product.

The PET mark is such that the heat resistance of the material is poor, and the maximum use temperature does not exceed 70 ° C, and it is preferably used at normal temperature. Common mineral water bottles and carbonated beverage bottles are basically made of this material;

The PE logos are high density polyethylene and low density polyethylene, respectively. HDPE is often used as a packaging for cleaning and bathing products and is generally not used for food packaging. LDPE is relatively soft and has a waxy feel. It is lighter in weight than the same plastic, has certain transparency, has good heat resistance and cold resistance, and has good chemical stability. The common use is food wrap and fresh-keeping bag;

The logo of PP is that the general PP use temperature is -6 ° C ~ 120 ° C, so it is suitable for hot rice hot dishes, can be heated in a microwave oven, or even cooked in a steam cabinet, the temperature of the modified PP can be controlled at - From 18 ° C to +110 ° C, the lunch box made of this PP can be used in the refrigerator instead of being heated to 100 ° C.

The recycling mark of PS is hard and easy to tear. The PS starts to soften when the temperature reaches 75 °C, so it is not suitable for hot meals. However, the low temperature performance of PS is very good. It is a refrigerated food such as ice cream and rice balls. The best packaging material.

Disposable plastic tableware products are inexpensive and are used frequently in everyday life and are almost everywhere. The quality of its products is also uneven. Jiuzhi Plastics Network Xiaobian recommends that consumers pay attention to the following points when purchasing disposable plastic tableware products:

Look at the logo. When consumers purchase disposable plastic tableware products, they must see whether there are QS signs, production license numbers, manufacturers, production addresses and other information to improve product quality assurance.

Look at the packaging. When purchasing disposable plastic tableware products, consumers should choose the well-packaged products, pay attention to the date of manufacture and shelf life, and try to choose the products during the warranty period to prevent bacteria and mold.

Look at the appearance. To choose disposable plastic tableware with smooth surface and uniform color, try to choose colorless and transparent products without decorative patterns.

Smell the smell. You can smell the smell and smell, prevent the food from being odorous and affect food safety.

Look at the hardness. Whether the product is too soft to be pinched, try not to choose a product that is too soft to pinch.

Finally, Xiao Bian suggested not to reuse disposable plastic tableware, and do not put food in disposable tableware for a long time. In addition, the use of the process should pay attention to the logo on the product, no microwave heating logo, do not use microwave oven heating.
