Is the plastic box good or the glass good?

Answer:

Plastic PP material box, non-toxic, tasteless, low density, strength, stiffness, hardness and heat resistance are better than that of low pressure polyethylene, can be used at 100 degrees. With good electrical insulation and high density is not affected by humidity, 0.90-0.91, high heat resistance, toughness and corrosion resistance are very good. One of the most commonly used food and plastic products. Disadvantages: brittle at low temperature, no wear, easy aging.

Plastic PET material, milky white or light yellow, highly crystalline polymer, smooth and shiny surface. It has excellent physical and mechanical properties over a wide temperature range. Heat resistant to 70 degrees, only suitable for warm drinks or frozen drinks, high temperature liquid, or heating, it is easy to deformation. Such as mineral water bottles, so do not take mineral water bottles hot water.

Glass preservation boxIt has toughened glass preservation box and heat-resistant glass fresh-keeping boxAdvantages: material safety, high transparency, heat-resistant glass can withstand high temperature.Disadvantages: high temperature tempered glass will crack, heavy fragile products, should not carry, tightness is not good.

It is the most warm yogurt. So are the same, the two do not have harm to human body. But recommend plastic, not broken, and portable, hand-held frozen convenience, conversely, glass inconvenience you want. You did not find the fuse box is now the plastic of the majority of all sorts of reasons? My answer is in the plastic material easy and grease reaction. The plastic box and a glass box which is better? There is no conclusion.

The glass composition is silica, inert, no oxidation; plastic components are polyethylene, is not good for health. So try to choose the glass bottle. You are the same, the plastic box called do not know if you have not read the instructions carefully, it is not plastic, it is food grade plastic, if not particularly hot stuff hot, harmful substances inside will not cause harm to humans.
