Is it safer to use PP cups and pet cups in disposable plastic cups?
04 Apr 2019
Disposable plastic cups are made of materials approved by the national security department. They are all environmentally safe materials. As for safety and insecurity, it is mainly determined whether the items contained in the user satisfy the nature of the two materials. The disposable plastic cup material used in the Miso disposable pet cup and PP cup has the following characteristics: Pet material features: 1. Has good mechanical properties, impact strength is 3 to 5 times that of other films, and good folding resistance. 2. Oil resistant, fat resistant, olefin resistant, dilute alkali, resistant to most solvents. 3. It has excellent high and low temperature resistance, can be used for a long time in the temperature range of 120 ℃, can withstand high temperature of 150 ℃ for short-term use, can withstand low temperature of -70 ℃, and has little effect on mechanical properties at high and low temperatures. 4. Low gas and water vapor permeability, excellent gas barrier, water, o...

Plastic containers such as plastic crispers and cups are used more and more widely in the home, especially in the summer. How to choose the right material to ensure safety? Wang Zhenhua senior engineer said that the bottom of the plastic product has a triangle with an arrow. The recycling mark, there is a number in the middle of the triangle, this is the code of the plastic material, according to this number to choose different materials of plastic appliances for different purposes. 1. stands for PET (polyester): common in mineral water bottles, carbonated beverage bottles This kind of beverage bottle can resist heat to 70℃, suitable for warm drinks or frozen foods. It is easy to deform when it is filled with high temperature liquid or heated, and harmful substances will melt out. After 10 months of use, PET may age and release harmful substances. Therefore, when the beverage bottle is used up, it should be discarded in time, and should not be used as a water cup or recycled for...
Plastic alloy blend
23 Mar 2019
Since a single plastic is difficult to meet complex use requirements, the plastics industry often mixes different plastics together to form a plastic alloy, which can not only exploit the advantages of different materials, but also save the cost of developing new materials. Main applications: Plastic alloys are widely used in a variety of structural materials. For example, the outer casing of the mobile phone is mostly PC-ABS alloy; some sewer pipes are made of two kinds of PE alloys, called bimodal polyethylene, in order to meet the performance and processing requirements. Note: Although combined with the advantages of a variety of plastics, but the material is still plastic, heat resistance is still the biggest drawback. However, most products in actual applications will not be exposed to high temperatures. As long as attention is paid to the application environment, plastic is definitely a good material for cheap use.

There are many types of ABS, which are widely used in various electrical enclosures, office supplies components, helmets, doors and windows, etc. In industry, ABS is often used for blending and modification of other plastics. Note: ABS is non-toxic, but it is mostly used for structural materials. Applications on daily ware packaging are rare. ABS has many advantages, but it still has the common characteristics of plastic: it is not heat resistant.

Another name for polyamide: nylon - everyone must be familiar. The polyamide family is very strong and has many varieties with excellent physicochemical properties. This is why PA is widely used in the electronics, electrical and automotive industries. In life, nylon rope and nylon socks are also common items. The spun PA fibers are called nylon and are used for fishing lines, fishing nets, ropes and conveyor belts. Commonly used in: nylon rope, nylon socks; fishing line, fishing nets, ropes and conveyor belts. Advantages: Nylon is non-toxic, has good heat resistance, especially heat resistance and is not easily deformed, so it can even be used for the manufacture of engine parts. Note: Nylon has poor ventilation and is easy to generate static electricity.

It is synthesized from bisphenol A and diphenyl carbonate, and is commonly used in the manufacture of kettles, cups, bottles and the like. In the process of making PC, the raw material bisphenol A should be completely made into plastic structural component, and should not be released in use, but the unqualified product can not be done, a small part of bisphenol A can not be completely converted into plastic, and it will be heated. It is released into food and is harmful to children and the fetus. (The 2011 PC bottle event is the result of this.) The most common water cup material at present, many department stores and car manufacturers use the water cup of this material as a gift. Commonly used in: life is often used in transparent cups, bottles, drinking buckets, CD substrates, lenses and lampshades. Advantages: good light transmission, good heat resistance and impact resistance, resistant to weak acid, weak alkali and neutral oil. Note: UV resistance and weather resistance are...
